Electromagnetic valve control system

Abstract

An electromagnetic valve control system electromagnetically opens and closes intake and exhaust valves in an engine having a crankshaft. The electromagnetic valve control system has a valve actuator for opening an intake valve, a valve actuator for opening an exhaust valve, and a valve actuator for opening an auxiliary exhaust valve before the exhaust valve is opened. The electromagnetic valve control system also has valve operation detectors for detecting actual operating conditions of the intake valve, the exhaust valve, and the auxiliary exhaust valve, a rotation detector for detecting the rotational speed of the engine and the angle of the crankshaft, a load detector for detecting the load on the engine, a controller for applying actuating signals to the intake, exhaust, and auxiliary exhaust valve actuating means in synchronism with a crankshaft angle signal from the rotation detecting means, based on the detected rotational speed and load, and for correcting the actuating signals based on detected signals from the valve operation detecting means.
