Know All About What is Engine Braking and its effect on your Car?

The best way to slow and stop your car in the safest way is through the use of foot brake both in normal conditions and emergencies. But there is another option available to the driver to slow the car- ENGINE BRAKING. In this blog, we discuss what is Engine Braking? how it is done, benefits and harm of engine braking to the car, and when engine braking is better than normal braking.

What Is Engine Braking?

Basically Engine Braking is a process of slowing down the car by releasing the accelerator and shifting down through gears, rather than through the use of the footbrake. In technical terms, it is using decelerative forces in the engine to slow the speed the wheels are turning at. This happens with the accelerator pedal is released, closing the air intake valve to create a vacuum. By restricting the airflow to the cylinders, sapping the energy and creating a braking force that brings the car to halt.

Engine braking works only when a car is in the gear. When the clutch is disengaged, the decelerative force created by releasing the accelerator is not transferred to the drivetrain, so the wheels keep on moving at the same speed. By shifting into the lower gear you can speed up the engine braking. The car can be brought to a controlled stop faster by higher RPM of the engine as more torque is transferred through the transmission.

How engine braking is done: It is a very simple process to engine brake in a manual transmission car, but it may take new drivers a few attempts to master it. Suppose you are driving at a speed of 40 km and you approach the traffic lights. If you want to slow, take your foot off the accelerator and switch to a lower gear such as third or second. This will slow down the car with the use of foot brakes. You can then use the clutch and brake technique to stop the car safely while limiting brake pad wear and tear.  For effective engine braking practice is necessary.

Benefits of Engine Braking:

Reduces Wear and Tear on Brakes: The key benefit of engine braking is that it reduces the wear and tear on the vehicle’s brake. As the drum brakes work on the principle of friction, they wear as an when the brakes are applied. With the use of traditional braking with foot and combining it with the engine braking, you can reduce the amount of wear to your car brake pads thereby extending the brake life to a great extent.

Provides better control to the driver: The other benefit of engine braking is that it provides better control to the driver, especially while driving downhill.  By selecting low gear before a descent car speed can be controlled through the engine and just through the brakes, making it less likely that calipers will overheat or in worst-case-situation stop working altogether.

 On Icy road, it reduces skidding: In icy road conditions, engine braking is useful. Due to the sheet of ice roads becomes slippery, and there are chances that you run the risk of locking the wheels and skidding by using foot brakes, especially if you panic and slam on the brake pedal. Engine braking can reduce this risk by helping you slow down with using the brakes, and you can control the speed of your car while keeping the wheels turning in snowy or icy roads.

Harms of Engine braking:

Engine braking gives high revs, so many drivers worry that the car engine is harmed. This all depends on how close to the line the RPM is and how long it stays there. Longer stays can harm the car engine.

It can overheat the engine when downshifting to a lower gear to perform an engine brake for a longer time. Driving too long with a high engine RPM can overheat the engine, placing strain on the radiator and cooling system. But higher RPM when below the red line, there are no risks to the engine- even if it sounds loud.

Engine braking can damage the transmission system. By jumping from a high to low gear quickly, unnecessary strain on gears and clutch plate is caused thereby inflating your clutch and gears repair bill. Brakes repairs are less costly than the transmission repair.

By shifting to low gears while driving downhill from the higher gear you can get an uncomfortable jolt. But the intensity of jolt can be reduced if you let your foot off the clutch in a slow and smooth motion. This also reduces the wear of the transmission system.

When Engine braking is better than normal braking?

In the normal driving conditions using the traditional foot brakes is a better and safest option to slow down your vehicle.  You can Engine brake in normal driving as a measure to reduce brake pad wear but – not as a safety measure. But there are some instances when engine braking is a more efficient option than using the footbrake to slow down the vehicle with the risk of skidding or overheating the brake pads to a point where they stop performing normal braking. Engine braking is a real lifesaver if you are driving downhill and if you are driving slippery and icy road.
