What is an engine brake ordinance?

How does engine braking work?
When activated, the engine brake alters the operation of the engine’s exhaust valves so that the engine works as a power-absorbing air compressor. This provides a retarding, or slowing, action to the vehicle’s drive wheels, enabling you to have improved vehicle control without using the service brakes*.
Is it OK to press clutch while braking?

Do cars have engine brakes?
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. This has the effect of sapping energy from the engine which is what gives that sudden sense of deceleration and drop in power.
