![]() ![]() This means less wear, less heat and less fade. Because the car is slowing passively it allows you to maintain control of the vehicle, controlling your deceleration so you only need to apply the brakes at much lower speeds for a much shorter period of time. It reduces wear on your brakes.Įngine braking slows the car without the need to apply the brakes. While some of the braking force is due to friction in the drive train, the majority is caused by the manifold vacuum created by the lack of air.Ĭheck out the video below which explains engine braking in a petrol engine, followed by Jake Braking in a diesel engine.Įngine braking, aside from being incredibly clever, has three distinct day to day benefits that could improve your driving experience. This has the effect of sapping energy from the engine which is what gives that sudden sense of deceleration and drop in power. In standard petrol (gasoline) engines, engine braking works by restricting airflow (by releasing the accelerator) which causes a high manifold vacuum that the cylinders have to work against. ![]() Not just for its sophistication but for the unbridled genius of its simplicity. However, changing the way you drive can not only extend the life of your brakes but make for a better driving experience too.Īs you will have gathered, we’re fans of the modern combustion engine. Of course brakes and rotors can fade over time and the more they’re used the quicker they fade. Of all the components in your car the brake assembly is the one thing that gets put under the most stress, most of the time but can’t ever fail. The list is long and quite amazing.īecause of this incredible sophistication, engines are designed to work under some pretty extreme tolerances which includes the brakes. Yes the basic building blocks are the same, but it has become so much more.ĭozens of parts from pistons to CPUs all work constantly to deliver power to the wheels, assist your steering, manage suspension, monitor tyre pressure, and tell the brakes you’ve pushed the pedal. Compared to its origins it is the evolutionary equivalent of man compared to the primordial soup. The modern engine is an incredible thing.
