please explain engine braking? the definition i found was " braking effect caused by throttle position induced vacuum in petrol engines".In what way is this better than external braking?
monty37 said:but Lsos explains engine braking only in petrol engines and jake brakes
are solely intended for diesel engines.
but won't engine braking affect the fuel efficiency?
Lsos said:Some people also use them in normal driving situations to "save the brakes", but I wouldn't recommend it. It also doesn't "increase your braking power", as your brakes can usually more than lock up all 4 tires. If anything, it would unbalance your brake-bias.

Engine braking is a technique used to slow down a vehicle by reducing the engine's power or by shifting to a lower gear. This allows the vehicle to slow down without using the brakes, which can help to prevent brake wear and reduce the risk of overheating the brakes on long descents.
When you release the accelerator pedal while driving, the throttle plate closes, reducing the amount of air and fuel entering the engine. This restricts the engine's power, and the vehicle slows down due to the decreased output from the engine. Additionally, shifting to a lower gear increases the resistance on the engine, further reducing the vehicle's speed.
In general, engine braking is considered to be better for your car than using the brakes. This is because it reduces the stress on the braking system, which can help to prolong its lifespan. However, it's essential to use both techniques together for an optimal driving experience, especially in emergency situations.
No, there are no significant differences in engine braking between petrol and external engines. Both types of engines use the same principle of reducing power to slow down the vehicle. However, external engines, such as diesel engines, tend to have more significant engine braking effects due to their higher compression ratios.
No, engine braking does not damage your car. It is a safe and effective driving technique that can help to reduce brake wear and improve overall vehicle performance. However, it's essential to use it correctly and not rely on it solely as it can cause the engine to over-rev in certain situations.
