How V8 Engines Work - A Simple Explanation


V8 engines operates under the same basic principles as any other gasoline four-stroke engine. First the piston pulls in air and fuel as it moves downward, then it compresses that air and fuel as the piston moves upward. A spark plug fires, igniting the air/fuel mixture and forcing the piston downward. Finally the piston pushes out the exhaust gases on its way back up, before for the cycle repeats itself.

In a V8 engine, this cycle is happening in 8 different cylinders, at different times. Instead of multiple cylinders firing at the same time, you want them to be spread out so that power delivery is smooth. For this Chevy V8, the firing or is 1, 8, 7, 2, 6, 5, 4, 3. With 8 cylinders, there is a cylinder firing for every 90 degrees of the crankshaft rotating, which means at any point in time, there are two cylinders on the power stroke.

With regards to the valvetrain, the intake air comes from the top of the engine, and into the sides of the cylinder head. The exhaust flows to the sides of the engine, exiting the exhaust valves from the cylinder head. In this LS3 model, there is a single intake valve and a single exhaust valve, though it’s also common to see engines with two intake valves and two exhaust valves. The larger valve is the intake valve, and the smaller valve is the exhaust valve.

The pushrod valvetrain gets its name from the metal pushrods which activate the rocker arms which open up the valves. The camshaft, located in the center of the V, has lobes on it which push the push rods up, opening the appropriate valves. For a full explanation of V8 engines, check out the video!

Building the Ultimate Work Truck | A Guide for Contractors and Equipment Suppliers



A good work truck shouldn’t just be reliable transportation—It needs to be a toolbox, a mobile office, a hauler, and more… Here’s a complete guide to building a work truck that works as hard as you do. Work Truck Job Requirements When it comes to the different work truck functions, here are some questions to get you started… Passengers. How many people will you have to fit? Some trucks offer a way to easily reconfigure the interior to accommodate more people or more cargo. Load. How much weight do you need to haul? If you regularly haul heavy equipment to job sites, you may want a truck with a high towing capacity. Tools. What kinds of tools do you need to keep handy in the truck? You’ll want a way to organize and secure them and may want to consider aftermarket accessories as well—But more about this later. Distance. How far do you travel each day? If you’re clocking in some heavy miles, a hybrid or all-electric work truck could save you some dough. Terrain. What kind of terrain will you travel on? You may not need an all-wheel-drive (AWD) if you’re just driving on regular pavement. Truck Size You want to be comfortable! One indication that the truck may not be the right size for you is your need to move the seat to maximum positions—For example, do you need to move all the way up and forward in order to see over the wheel? Or will you want to lower the seat and recline it in order to avoid hitting your head? Don’t judge a truck by a photo, alone—You’ll want to take a seat inside the real thing! Truck Hauling and Towing If you regularly move equipment and other heavy items, we recommend getting the highest rated towing capacity that you can afford. For some, sacrificing interior space for a longer truck bed will suit their hauling needs. It is not necessary to buy a work truck large enough to tow items that you rarely have to transport. In the event you have a super heavy load, you can always just lease a larger truck. Truck Wheels You’ll want the type of wheels that can handle the terrain you are most likely to encounter on a regular basis. Some like the look of oversized tires, but it can be harder to get into a truck that is high off the ground. You can be dazzled by expensive rims, but you’re going to work, not a truck show. These are opportunities to save money to buy more practical accessories. Truck Safety Airbags are standard these days, but some newer work trucks include some impressive safety features, including braking when a living being is detected in front of you or warning you if you start to drift into another lane. And backup cameras are getting more sophisticated with guides to help you back into spaces and warning signals when you’re getting too close to a wall. Tools
There are several ways to organize your tools. Here are just a few options: Decked offers a unique drawer system that doesn’t take away your bed space. Bedslide makes it easy to slide your tools and equipment out from your truck. Weather Guard has their line of Pack Rat pull out storage in various sizes. Ram offers the Rambox Cargo Management System on some models. It has locked storage that lines the bed of the truck.

2022 GMC HUMMER EV Edition 1’s Outstanding Performance Powered by Ultium


 Ultium 24-module battery system
  • Three-motor Ultium Drive system with GM-estimated, best-in-class 1,000 horsepower and combined axle torque of GM-estimated 11,500 lb-ft
  • Segment-exclusive available driving modes, including Watts to Freedom1, CrabWalk2 and available Extract Mode3
  • 800-volt 350-kilowatt DC fast charging capability4
  • First GMC EV with brand-first Regen on Demand5, Super Cruise6 available driver assistance feature for compatible roads

DETROIT – The 2022 GMC HUMMER EV Edition 1 will be the first vehicle in production with GM’s all-new Ultium battery architecture and will offer impressive on- and off-road features and a broad range of vehicle dynamics and performance features.

This new architecture provides the framework to integrate advanced technologies for optimal driving range and — in the case of the HUMMER EV — will enable performance and capabilities that would not be possible with a conventional vehicle architecture and propulsion system.

The 24-module Ultium battery pack and three-motor Ultium Drive system will provide this all-electric supertruck best-in-class power output.

“As the first of GM’s next-gen EVs, the HUMMER EV will fundamentally alter conventional off-road and truck paradigms,” said Ken Morris, GM vice president, Autonomous and Electric Vehicle Programs. “It will also debut new technology, including our all-new Ultium batteries, Ultium Drive units and the industry’s first wireless battery management system.”

Ultium cells

Ultium batteries are unique in the industry because of their large-format, pouch-style cells, which can be stacked vertically or horizontally inside the battery pack. In the Edition 1 HUMMER EV, two layers of vertical cell modules will be used to produce a combined 24-module pack offering a GM-estimated range of 350+ miles7.

In addition to power and range, the Ultium battery pack will contribute to the HUMMER EV’s driving dynamics and structure. The pack’s low mounting position in the chassis contributes to a low center of gravity, enhancing the vehicle’s overall feeling of control and stability. The compact construction of the Ultium battery pack also contributes to HUMMER EV’s ideal off-road proportions, including a short front overhang and short front breakover angle.

With GM’s state-of-the-art nickel, cobalt, manganese, aluminum (NCMA) chemistry, HUMMER EV’s Ultium batteries will have some of the highest nickel and lowest cobalt — a rare and costly material — content of any large-format pouch cell. The breakthroughs of the Ultium chemistry allow GM to use 70 percent less cobalt than GM’s previous generation of EVs.

HUMMER EV will also be the first vehicle in GM’s lineup to feature its wireless battery management system, which maintains balance within the truck’s battery cell groups for optimal performance and battery longevity.

Electrifying off-road

This is the first truck that we have ever designed around an EV propulsion system,” said Adam Kwiatkowski, GM executive chief engineer, Global Electric Propulsion. “Designing the truck and the propulsion system together enhances HUMMER EV’s unique performance capabilities, while also making this the stiffest truck GM has ever built.”

Edition 1’s three electric drive motors within Ultium Drive will yield a combined GM-estimated 1,000 horsepower, and when multiplied through the front and rear drive unit gear ratios, there will be more than a GM-estimated 11,500 lb-ft of torque available at the wheels.

The single-motor front drive unit will have a 13.3:1 fixed gear ratio and will offer an electronic lockable differential, capable of delivering up to 100 percent of the motor torque to one wheel, in case traction is lost on the opposite wheel. All four wheels can be fully synchronized for true e4WD propulsion.

Two rear motors contained in one Ultium Drive unit will independently power the rear wheels through a fixed gear ratio of 10.5:1, with the capability of varying torque output to each wheel to optimize traction in off-road driving and highway-driving conditions. Motor output can also be synchronized to simulate a locking differential.

The system’s pure electric propulsion holds peak torque much longer, through a wider speed range (up to 40 mph) than even diesel engines, which is optimal for off-roading, but also thrilling on-road. For straight-line performance, the Ultium batteries and Ultium Drive will offer enough power to enable the Watts to Freedom performance feature, launching the HUMMER EV from 0-60 mph in approximately 3 seconds (based on GM estimates).

DC fast charging

HUMMER EV will have the ability to take advantage of the industry’s fastest 350-kilowatt DC fast chargers4. This vehicle will offer a GM-estimated 350+ miles7of range based on preliminary testing, with a unique ability to switch its battery pack from its native 400-volts to 800-volts for charging. A disconnect unit and mechanization within the pack enables the battery to switch from “parallel” to “series,” allowing it to add nearly 100 miles of range in 10 minutes of charging8.

The charging system is also designed to support legacy 400-volt charging infrastructure, without the need for a converter box or other accessories, allowing HUMMER EV to use a variety of charging stations.

The HUMMER EV’s charging hardware will be complemented by in-vehicle and available smartphone apps that help customers find available charging locations and can even precondition the battery to get the most efficiency out of their upcoming charging session.

Energy Assist

The HUMMER EV’s in-vehicle Energy Assist, also part of the myGMC mobile app9, will monitor the vehicle’s energy use, and sets up a charging schedule, preheating the battery en route to the charging station for optimal charging and learning to drive more efficiently to maximize range and more. It is accessible through the infotainment system12 and designed with a simple, intuitive interface with easy-to-understand icons.

Regen on Demand5, one pedal drive10

HUMMER EV is the first GMC vehicle to offer variable Regen on Demand5, a driver-controlled regenerative braking feature, which converts the kinetic energy of the truck’s forward momentum into electricity stored in the vehicle’s battery packs for maximizing the driving range.

This standard feature is compatible with all of HUMMER EV’s available drive modes. Unlike other EV regenerative braking features, Regen on Demand allows the driver to decide when and to what extent the system should be used. With the pull of a steering wheel paddle, drivers can even slow the vehicle to a full stop without engaging the brake pedal. If the driver anticipates the need to decelerate the truck, he or she can engage Regen on Demand before lifting off the accelerator pedal, for a greater measure of control.

HUMMER EV also features one pedal driving10 through a driver-selectable Terrain Mode, which provides low-speed, one-pedal control for driving over off-road terrain and obstacles.

Super Cruise6

The GMC HUMMER EV will launch with the latest version of Super Cruise6, which includes a new automatic lane changing feature, where the system can determine when a lane change is optimal and initiate the maneuver, while following signaling protocols. Super Cruise capability with three years of service comes standard on HUMMER EV and is available on more than 200,000 miles of compatible roads in the U.S. and Canada.

Super Cruise is the industry’s first true hands-free driver assistance systemUnlike others, it uses two advanced technology systems: a driver attention system and precision LiDAR map data. Recent enhancements to Super Cruise include performance and ease-of-use updates, including richer map information, improved software controls and user interface improvements to make Super Cruise more intuitive.

The HUMMER EV is the first full-electric vehicle in GMC’s portfolio and is powered by General Motors’ new Ultium battery system. Production begins in late 2021, at GM’s Factory ZERO, Detroit-Hamtramck Assembly Center11— a nearly 40-year-old facility repurposed and retooled with a $2.2-billion investment devoted to electric vehicle production. Future production vehicles out of the factory will offer zero emissions.

Performance targets, estimates and capability specifications based on computer-aided analysis and simulation using virtual engineering tools. Estimates may vary depending on model and trim. Additional model and trim details can be found at GMC.com. Actual production model and results may vary.

New Crash Tests Show Modest Speed Increases Can Have Deadly Consequences - IIHS News


Drivers want to save time, and local transportation agencies want to improve traffic flow, but at what cost? With posted speed limits increasing on roadways around the country, a vehicle’s ability to protect drivers in crashes is in doubt.

Small speed increases can have huge effects on crash outcomes, as shown in new crash tests by the AAA Foundation for Traffic Safety, the Insurance Institute for Highway Safety (IIHS) and Humanetics. The safety organizations conducted crashes at three different impact speeds (40, 50 and 56 mph). They found the slightly higher speeds were enough to increase the driver's risk of severe injury or death.

10 Reasons Why Engines Lose Power Over Time


There are four things a gasoline engine requires to generate power and almost any engine problem will come down to something relating to one of these four factors. 1. Air 2. Fuel 3. Compression 4. Spark

Dirty Air Filter
A clogged air filter makes the engine work harder to pull in air, and can restrict the maximum amount of air let in. Less air means less power.

Exhaust Restrictions
The engine will have to work harder to push out exhaust gases, limiting power. Catalytic converters can clog up on engines with an improper air/fuel mixture or as a result of fuel additives reacting within. Mufflers can also fail internally, and alterations of the internal piping can result in an airflow restriction.

Fuel Injectors
Deposits can build up on the injectors over time from heat soak or poor fuel. Small restrictions can cause the O2 sensors to read a lean mixture, and so more fuel will be added to compensate. This can result in a rich mixture for the cylinders without injector problems, or even misfiring if the injector isn’t capable of injecting enough fuel.

Fuel Pumps
Overtime the fuel pump can wear out, but it might not necessarily fail catastrophically. While it may still be able to supply fuel at lower pressures, it may begin to struggle to provide fuel at higher pressures or for longer durations.

Worn Piston Rings
One of the major things that can happen over time is the piston rings will wear down, and this will allow for blow-by. Some of the high pressure air and fuel mixture combusting will pass by the pistons and travel along the cylinder walls into the crank case. This is pressure that should be pressing the piston down, so power is lost. It also means less compression as some of the air can escape as the piston travels upward on the intake stroke.

Carbon Deposits On Intake Valves/Valve Seats
If carbon deposits build up on the valves or valve seats, this can prevent the valves from closing properly. If an intake valve cannot fully close, it will allow air to escape during the compression stroke, effectively lowering the compression ratio.

Carbon Deposits On The Piston
If deposits build on the piston or cylinder walls, these deposits can create hot spots. These hot spots can result in engine knock if conditions allow for it. If the engine is capable, it will retard the ignition timing to reduce the likelihood of knock. By retarding the ignition timing, power is lost.

Fouled Spark Plugs
Spark plugs can build deposits with time. Inconsistent spark plug firing means you’re likely to misfire. Maintaining clean plugs ensures that the spark part of the equation doesn’t result in a loss of power.

Compared to other cushion hitch solutions, ShockDrop™ is lighter-weight, putting less stress on your receiver hitch.

For maximum confidence, ShockDrop™ technology is engineered for simplicity. Each product is designed to be virtually maintenance-free. The cushion isolator is thoroughly tested for thousands of cycles, and it won’t wear out like competitive solutions that use an airbag or bearings.

Off-Road Performance Edition Takes GMC Canyon AT4 to New Heights

Suspension leveling kit, rocker panel protectors and aluminum skid plates among features that elevate the confidence and capability of the Canyon AT4


DETROIT – Today, GMC announced the new 2021 GMC Canyon AT4 Off-Road Performance Edition, which enhances the Canyon AT4 and enables customers to confidently venture into rugged off-road environments, all while maintaining the premium comforts they have come to expect from GMC.

“When customers are looking for a capable off-road truck, we know that they want improved vehicle height as well as additional protection,” said GMC Marketing Director Rich Latek. “Whether it’s tackling die-hard off-road courses or embarking on a weekend adventure, the Canyon AT4 Off-Road Performance Edition provides an improved approach angle, enhanced maneuverability and underbody protection to key parts of the truck, while still delivering a premium GMC experience.”

When the Canyon AT4 debuted in January, its bolder design and premium detailing combined with confidence-inspiring capability signaled the brand’s continued commitment to offering premium, off-road capable vehicles.

Standard equipment on the Canyon AT4 includes 31-inch Goodyear Wrangler DuraTrac® tires, an off-road tuned suspension package with Advanced Hill Descent Control System and a four-wheel drive system with Eaton G80 Rear Automatic Locking Differential.

The Canyon AT4 Off-Road Performance Edition builds on this foundation to provide even more capability for drivers whether they’re venturing far off-road or navigating a trail. A suspension leveling kit and the removal of the front air dam improve the truck’s approach angle by more than 35 percent to nearly 30 degrees.

This increased approach angle is paired with rocker panel protectors and performance front and mid skid plates to provide increased off-road capability and maneuverability. The skid plates are made from sturdy, 5/32-inch aluminum and help protect the lower radiator, front differential, steering gear and oil pan. In combination with the transfer case shield standard on the Canyon AT4, the Off-Road Performance Edition offers the protection to the majority of the truck’s powertrain that off-road enthusiasts expect.

The Off-Road Performance Edition elevates the bold styling and premium refinement of the Canyon AT4 with the addition of:

Unique 17-inch Gloss Black wheels

Carbon Black AT4 logos

Gloss Black performance exhaust tip

After a day of off-road adventure, additional protection for the interior and the truck bed is provided in the form of accessory floor liners and spray-in bedliner.

The 2021 Canyon AT4 Off-Road Performance Edition will be available to order later this year. For more info, visit www.gmc.com.
