Are the Car Transmission and Engine Integrated as One Unit?

[JamesLee]

Car transmissions and engines are not integrated as one unit. The transmission is a mechanism designed to alter the rotational speed and torque from the engine, capable of fixed or stepped changes in the gear ratio between the output and input shafts. Its components include: gear transmission mechanisms and control mechanisms, categorized into: manual transmissions, automatic transmissions, manual-automatic integrated transmissions, and CVT continuously variable transmissions. An engine is a machine that converts other forms of energy into mechanical energy, including: reciprocating piston engines, Stirling engines, steam engines, jet engines, and electric motors. The function of the transmission is to modify the gear ratio, delivering appropriate traction force from the driveshaft to the wheels, ensuring the vehicle meets requirements under various operating conditions and providing continuous power to the vehicle.
