A rev limiter is there for your benefit. Without it, you'd be facing down a potential busted engine and trickier launches, especially in higher horsepower vehicles. If you have a vehicle with a launch control mode, then you have a car fitted with a two-step rev limiter. One step is designed to help you get off the line as quickly and efficiently as possible, while the other step is there to protect your precious spinning engine parts. Jason Fenske from Engineering Explained is here to tell you how it all works. With the first rev limiter, the computer tells the engine to hold at a certain...

Learn what a final drive ratio is and how it affects your car
The final drive ratio is the last bit of gearing between your transmission and the driven wheels. By changing it, you can affect the performance of your car, rather dramatically in some cases. In general, a lower final drive ratio will lead to less torque at the wheels but a higher top speed...

Here are the differences between Variable Valve Lift and Variable Valve Timing
Engines are complex bits of machinery. At their core level, yes, it's easy to understand what is happening. Air and fuel enter the engine where they are ignited and combustion occurs resulting in power that turns shafts. CHECK OUT: Classic video explains how a planetary gear set works In a modern...

Can a big enough hill recharge a Tesla?
Like most other electric and hybrid vehicles on the market, the Tesla [NSDQ:TSLA] Model S and Model X are both fitted with a system that allows them to recapture energy and put it back into the battery pack. The most common manner in which this is done is through a regenerative braking system...

The differences between wet and dry sump oil systems
All of those moving parts in your engine create heat through friction, and that heat needs to be mitigated or bad things will happen. This is the task of your oil. It lubricates and cools engine components. Your vehicle will most likely move this oil around by way of a wet sump oil system. If you...

How Nissan's VVEL engines work
The letters VVEL are important to the architecture of Nissan engines. Those four letters stand for Variable Valve Event and Lift. What that refers to is a Nissan engine that operates without the use of a throttle body. Instead, the air flowing into the engine is metered by way of the cams and...

Believe it or not, the 2017 Honda Accord Hybrid sedan actually has something in common with an ultra-exotic hypercar produced by the Swedish brand Koenigsegg. That seems far fetched, and no we're not referring to the fact that both vehicles utilize four wheels wrapped in rubber tires. The similarity is related to the fact that both the Accord and the Koenigsegg Regera make use of a hybrid system that allows the engine to directly drive the driven wheels without going through a transmission. CHECK OUT: Ford Mustang Hybrid due in 2020, and it may be powerful Our friend Jason Fenske from...

Besides fuel, oil is the lifeblood of your vehicle. It keeps your engine rotating smoothly. This is accomplished by the properties of oil that allow it to lubricate moving parts and reduce heat generated by friction. If the moving parts in your engine weren't lubricated, you'd hear a lot of screeching noise followed by a car that doesn't really want to go anywhere. How does it all work? Jason Fenske from Engineering Explained is here to walk us through it all. CHECK OUT: 2018 Mercedes-AMG E63 first drive review: The deep-knee Benz The discussion above goes into the nitty gritty related to how...

How the elusive 4-rotor rotary engine works
As the old saying goes, there is no replacement for displacement. That's not the case when it comes to rotary engines, which typically have very small displacement. Instead of cubes, if you want a rotary to make more power you do two things: add more rotors and/or slap on a turbocharger or two...

Drag. Friction. Weight distribution and load. These are things you need to consider when you begin to think about how tires work. Yes, those four bits of rubber are your only connection to the ground and they keep your car moving in the direction you desire. Most of us think that a wider tire is better, and if it's more grip you seek then you're probably right. This is why. Jason from Engineering Explained is ready to break it all down. Basically, you want an evenly spread load across your tires. If you make your tires wider, it becomes easier to achieve this. A larger contact patch on the...

Developing parts for road cars vs. race cars
Road cars and race cars are very different. The cars we buy for every day driving are much heavier, due in part to safety and emissions equipment. Race cars shed every ounce of weight in the pursuit of speed. But those aren't the only differences. In some ways, road cars that are meant to last for...
