Operating multi-cylinder IC engine with solenoid actuators for gas exchange valves designed so that individual actuators respectively of a gas exchange valve type are controlled at least

摘要

The operational method is carried out so that individual actuators (14-19) respectively of a gas changing valve type (4,5; 8-11) are controlled at least frequently, if their temp. raises to a critical value and-or the IC engine is operated in a critical operating range. With several inlet valves or outlet valves per cylinder (1,2). The actuators (16,17;18,19) respectively of a gas changing valve type of the same cylinders are alternately controlled.
