motorfék

Motorfék, also known as engine braking, is a technique used by drivers to slow down a vehicle using the engine's resistance rather than the service brakes. This is achieved by downshifting to a lower gear. When a lower gear is selected, the engine's internal friction and the resistance of the pistons moving against the compression of the air-fuel mixture create a braking effect. This effect is more pronounced the lower the gear and the higher the engine RPM.

Motorfék is particularly useful in situations where prolonged use of the service brakes could lead to overheating and reduced effectiveness, such as descending steep hills. It helps to maintain a controlled speed without excessive wear on the brake pads and rotors. Additionally, motorfék can be used in conjunction with service brakes to supplement stopping power. Drivers often use it to anticipate stops or slow down gradually.

The effectiveness of motorfék varies depending on the vehicle's transmission type. Manual transmissions allow for direct control over gear selection, making engine braking a straightforward technique. Automatic transmissions also provide options for engine braking, often through a manual or "sport" mode that allows the driver to select lower gears, or through specific "low gear" settings. Drivers should exercise caution when using motorfék, especially on slippery surfaces, as abrupt downshifts can cause the drive wheels to lose traction.
