What does excessive intake camshaft retardation mean in a Smart car?
1 Answers
Excessive intake camshaft retardation refers to a phenomenon where the engine's timing system experiences delayed ignition. This can result in excessive engine vibration and difficulty starting the vehicle. Below is relevant information about camshafts: Camshaft function: Its role is to control the opening and closing actions of the valves. Although in four-stroke engines the camshaft rotates at half the speed of the crankshaft (in two-stroke engines they rotate at the same speed), the camshaft typically still operates at high speeds and must withstand significant torque. Camshaft working principle: The key component of a camshaft is its cam lobes. As the camshaft rotates, the cams open/close the intake and exhaust valves in precise coordination with piston movement. Therefore, the cam profile directly affects engine performance at different speeds.
