HINTERGRUND DER ERFINDUNGBACKGROUND OF THE INVENTION
Verbrennungsmotoren (IC-Motoren) erzeugen Drehmoment durch Verbrennen eines Luft/Kraftstoff-Gemisches. Das Drehmoment schafft eine Vortriebskraft für die Räder über ein Getriebe und andere Antriebsstrangkomponenten.Internal combustion engines (IC engines) generate torque by burning an air / fuel mixture. The torque provides propulsive power to the wheels via a transmission and other powertrain components.
