ABSTRACT:
A multi-cylinder, two- or four-stroke Diesel engine with electronic control, comprising piston-and-crank assembly, electropneumatically or electrohydraulically controlled inlet and exhaust valves, and injectors supplied with fuel under a high pressure, provided with control depending on at least one operational parameter of the engine, characterized in that with the main shaft a digital transducer of the angular velocity (5) is coupled, the transducer being further connected with the first input of the computer (6), over a shaping element (7). To the second input of the computer (6) an assembly of analog-to-digital converters (8) is connected, and to the assembly the sensors (9) of the operational parameters of the engine and of the charge exchange are connected. The first output of the computer is connected to an electronic actuator (10) which further transmits, to individual injectors, a current pulse having a duration corresponding to the operating time of the injector electromagnet, whereas the second output of the computer (6) is connected to an electronic actuator (11) which further transmits, to individual inlet valves, pulses controlling the actuators for opening and closing of the valves. The third output of the computer (6) is connected to an electronic actuator (12) which further transmits, to individual exhaust valves, pulses controlling the actuators for opening and closing the valves, and the fourth output of the computer (6) is connected to an electronic actuator (13) which acts on the power receiver of the engine to change its load in accordance with the optimum setting of the fuel charge for the given rotational speed of the engine.
