What does engine braking mean? Engine braking does not mean breaking connection between engine and drive wheels, but using resistance of engine cylinders and internal friction to form a braking effect on drive wheels to reduce speed of vehicle.
(1) Engine braking features:
Depressing accelerator gives power, loosening accelerator changes resistance, lower gear, greater resistance force. Generally, during pre-emptive braking and on long slopes or slippery roads, engine braking is often used to make full use of engine braking effect, which can not only save fuel, but also reduce tire wear and prolong life of wheel brakes. .
(2) Engine brake operation method:
When you need to slow down, release accelerator, do not press clutch, do not disengage or downshift, engine braking effect will be more significant. On icy and snowy roads or relatively slippery roads, engine braking should be used to maximum, which can effectively prevent vehicle from skidding. When using engine braking, low gear and high speed are strictly prohibited, because wheels force engine to run at high speed, which may damage engine and transmission components. If engine speed is too high, brake and slow down in time. Only when an automatic transmission vehicle is in 1st, 2nd, or L gears does engine produce a braking effect.
The above is an engine braking operation, you understand? I hope my exchange can solve your problems.
