How It Works

  • How do disconnecting sway bars work?

    You off-roaders out there know all about disconnecting your own sway bars. You crave articulation, and you'll disconnect parts of your vehicle to get it. For those who don't seek out tough trails and mud-covered body panels, the idea of a disconnecting sway bar might be an odd concept. It's less odd when you listen to Jason Fenske from Engineering Explained talk about it. A sway bar provides stability and helps to mitigate body roll in a car or truck. It's a great bit of bent mental that helps keep your vehicle feeling planted on the road. You don't want that when you're crawling off road...

  • Engineering Explained is testing their newly installed Honda S2000 rear differential
    Can a gearing change make your car quicker?

    If you change your car's gearing, can you make it quicker? The simple answer is yes. More aggressive gearing creates a quicker car but not a faster car. A gearing change will have a noticeable affect on your car. If you swap in taller rear gears, you can gain some top-end speed, making your car...

  • How hot does an exhaust system get?
    This is how hot your exhaust system can get

    When your car is running, your exhaust system takes the hot waste gas from the engine and expels it out the series of tubes bolted to the underside of your vehicle. From your exhaust manifold, you typically move down to a catalytic converter and through some more plumbing before hitting the muffler...

  • Engineering Explained discusses the reasons why you should buy good tires

    When you buy a new car, the odds are good that it's going to come with solid tires. If that new car you're buying is a sports car or performance-oriented model, then the odds are even better that your car, truck, or SUV will have some seriously capable rolling rubber at all four corners. Now, if you buy a used vehicle or when it comes time to replace your tires, you shouldn't be looking to cheap out. You need to buy the best set of tires that fit your budget, and Engineering Explained is here to tell you why. The easiest way to understand why you need to spend more on your tires is to...

  • Engineering Explained: How hot do brakes get?

    It’s common knowledge brakes heat up during use, but how hot can they get? Simply put, pretty darn hot. Jason Fenske from Engineering Explained is back with another intriguing video made with help from a $55,000 FLIR thermal camera. This time, he points the camera at the brakes and takes some measurements. The camera shows us five specific points where heat is registered: the leading edge of the brake pad, the rotor before the brake pad, the rotor after passing through the caliper, the wheel hub, and the back of the brake pad itself. CHECK OUT: Watch engines warming up as captured by...

  • The science behind Individual Throttle Bodies
    The benefits of Individual Throttle Bodies vs. a single throttle body

    Your average new car has a throttle body and an intake manifold. The engine sucks in air through the air filter before it passes through the open throttle body and into the manifold. From there, it moves into the cylinders as called upon during the combustion cycle. You'll find one throttle body...

  • Engineering Explained talks about McLaren suspension and its lack of sway bar

    McLaren is a company that loves pushing the technological envelope. Be it the company's road cars or its racing machines, there is plenty of fascinating bits to be explored under the skin. One area that's proven to be rather interesting is in regards to the suspension employed on a number of modern McLaren road cars. With a traditional vehicle, you'll find springs, coils, and sway bars playing a role in the suspension setup. These works together to mitigate and control both up-down motion as well as side-to-side rocking motion. The sway bar is what helps control that side-to-side action. In...
