How It Works

The 4-cylinder engine has become a standard across the automotive industry thanks to its compact size and efficiency. But, one variant of 4-cylinder engine doesn't rule. There are two popular variations of the 4-cylinder engine: inline-4 and flat-4. Each comes with benefits and downfalls, which is...

The inline-4 engine has become a standard powertrain across most automakers' vehicle lineups, due mostly to its small size and efficiency. But, have you ever wondered how inline-4 engine actually operates? Thanks to 3D printing technology, and Engineering Explained's Jason Fenske's commentary, we...

While it may seem like blasphemy that an air conditioning unit can be used to actually increase horsepower, it's true. Dodge has implemented such a process to help the 2018 Challenger Demon create its immense 840 horsepower, but how exactly does it work? Thankfully, we can always count on Jason...

No matter if you buy a new car, a pre-owned car, or lease a vehicle, maintenance is unavoidable. And at some point, the brakes will need to be replaced. Although many will let a mechanic take care of the work, it's not a terribly difficult process. Jason Fenske from Engineering Explained is here to...

Jason Fenske from Engineering Explained is once again joined by his friend Charles from Humble Mechanic in this latest informative video which looks at forced induction. Specifically, the topic at hand is about what it takes to add a turbocharger to a non-turbocharged vehicle. Obviously, you'll...

Subaru has carved a niche in the vast automotive industry by doing one thing: equip every single car it sells with an all-wheel-drive system. That's minus the BRZ, of course, which features rear-wheel drive. How does Subaru's system actually work? Jason Fenske of Engineering Explained is here to...

The term is thrown around often, but what actually constitutes Subaru's "boxer" engine? With the insightful mind of Jason Fenske and a 3-D printed model of a 4-cylinder boxer engine, we're all in for some learning. In this video, Jason, host of Engineering Explained, walks viewers through the...

The upgrades continue for the Engineering Explained Honda S2000. The YouTube channel's host, Jason Fenske, is using his yellow sports car for more than just whipping around his local backroads, as it's also serving as a bit of a teaching tool. As he upgrades the car, we're all going to learn...

EV West has shown us the proper way to break down a Tesla Battery pack. They remove multiple modules in order to reuse them under the skin of cool projects. What if you just want to rip open a module to see what's inside? Well, you don't need to do it as cleanly as EV West. Instead you can just...

Maybe not so shockingly (pun intended), many drivers don't know how an electric car actually works. For many, the knowledge spans as far as plugging it in, letting charge, and driving it off. It's not really as simple as that, even though an electric motor is comprised of far fewer moving parts...

A sinkhole is a devastating, geological assassin. It arrives seemingly out of nowhere and can cause serious destruction to roadways, homes and cars. But how does such a dangerous situation manifest right below our feet and tires? It's mostly related to water. This video provides a great visual...

The Volkswagen Group loves its EA888 engine, found in popular models such as the Volkswagen Golf and Audi A3. This is the turbocharged inline-4 available as a 1.8-liter or a 2.0-liter and with power outputs ranging from about 170 to a bit over 300 horsepower. It also has a unique exhaust manifold...

Are you curious about the bits and pieces that make your car do its thing? Sure you are, and today is a good day for you. That's because we've got a video here that will take you on a deep dive of your fuel pump. We're talking abyss levels of deep here. The fuel pump gets removed for your viewing...

There's a balance to be found when you're on the hunt for a set of wheels and tires for your vehicle. Do you prioritize comfort over performance? Are you looking to increase the handling capability and feel of your car? Perhaps you want to wind up somewhere in the middle of the two ends of the...

A modern vehicle can do a number of things for its driver. It can regulate traction, keep your braking pressure from locking your stoppers up, and make sure your engine doesn't exceed a given rev limit. Heck, a modern car can keep you in your lane and stop you from hitting the car in front of you...

Tires are an absolutely essential part of any car, truck, or SUV. Compounds can create unique handling experiences suited for any type of vehicle, and they can even make a car much more fun to drive. It's also a common saying that wider tires provide more grip. In the interest of science, Jason...

A Nissan Titan weighs 5,811 pounds. A Mini Countryman weighs 3,629. The former requires a shorter distance to reach a complete stop from 60. Sounds crazy, but it's true, and Jason Fenske from Engineering Explained is here to, well, explain how the full-size pickup truck can out-brake a Mini...

The Lamborghini Huracán Performante is the king of the Nürburgring. It currently holds the track's quickest lap time of 6:52.01, and it ousted the Porsche 918 Spyder in the process from the top spot. How did it get there? We're glad you asked. So is Jason Fenske of Engineering Explained...

By this point, as we enter the middle of May, most drivers who use soft-compound winter tires have likely switched them out for a set of all-season rubber, or even some higher-performance summer-only tires. However, what happens if you keep those winter tires on your car and run them in warm...

It's a problem many may not know they're experiencing until flashing lights in the rearview mirror tell them otherwise. How do you know if your vehicle is reading an accurate speed? And if it isn't accurate, how do you go about fixing the problem? Have no fear, because Jason Fenske from Engineering...
