What are Engine Brakes?

Engine brakes, also known as Jake brakes or compression brakes, are devices that use the engine’s compression to slow down the vehicle. They are typically used on large trucks and buses, but can also be found on some passenger cars.

Engine brakes work by closing the engine’s intake and exhaust valves. This prevents the engine from drawing in air and fuel, and it also prevents the exhaust gases from escaping. This creates a vacuum in the engine, which slows down the crankshaft and the wheels.

Engine brakes are very effective at slowing down a vehicle, and they can be used to save fuel and brake wear.

Do Cars Have Engine Brakes?

Some cars do have engine brakes, but they are not as common as they are on trucks and buses.

The most common type of engine brake on cars is the exhaust brake. Exhaust brakes work by redirecting the exhaust gases back into the engine’s intake manifold. This creates a backpressure in the engine, which slows down the crankshaft and the wheels.

Exhaust brakes are less effective than Jake brakes, but they are also less expensive and easier to install.

Benefits of Engine Brakes

* **Reduced fuel consumption:** Engine brakes can help to save fuel by reducing the amount of time that the engine is running.
* **Increased brake wear:** Engine brakes can help to save brake wear by reducing the amount of time that the brakes are used.
* **Improved safety:** Engine brakes can help to improve safety by providing a more effective way to slow down the vehicle.

Conclusion

Engine brakes are a valuable tool for slowing down large vehicles. They can help to save fuel, brake wear, and improve safety. While engine brakes are not as common on cars as they are on trucks and buses, they are still available on some models.
