Moottorijarrutuksella
Moottorijarrutus, also known as engine braking, is a technique used in driving where the vehicle's engine is used to slow down the vehicle instead of relying solely on the service brakes. This is achieved by downshifting to a lower gear. When the driver takes their foot off the accelerator and downshifts, the engine's internal friction and the resistance of the drivetrain components create a braking effect. The engine acts as an air compressor or a pump, converting the vehicle's kinetic energy into heat and sound, thus slowing its momentum.
The effectiveness of moottorijarrutus is dependent on the gear selected and the engine speed. Lower gears and
In manual transmission vehicles, moottorijarrutus is a natural consequence of shifting gears. In automatic transmissions, some
