Reference Answer
Modern Camshaft-less Engines
Modern camshaft-less engines are termed intelligent engines because they are electronically controlled with the help of a central control unit. This unit governs the opening and closing of inlet and exhaust valves, fuel injection timing, and all other engine operating conditions.
Each unit is equipped with a PCB-based control system.
A sensor fitted on the flywheel detects the crank angle and, based on this input, the system controls the operation of the fuel injectors, exhaust valves, and starting air valves.
