Abstract

1277989 Engine control systems DAIMLERBENZ A G 26 March 1970 [28 March 1969] 14796/70 Heading G1N [Also in Divisions F1 and G3] In an I. C. engine control system, operation of the or each inlet and exhaust valves 10, 11 and fuel injection is controlled electronically from a controller 12 in dependence primarily upon the phase angle of the crank-shaft and the position of the accelerator pedal. The inlet and exhaust valves 10, 11 are actuated by magnetic valves 22, 31 which receive control signals from the controller 12 and are inserted between highpressure accumulators 23 and pistons 21 attached to the inlet and exhaust valves. A magnetic valve 31 is provided between the fuel supply and the fuel injector 32. Phase angle and rotational speed of the crank-shaft are determined by a pulse transmitter 17, 18, 19, and position of the pedal 14 by a potentiometer 15. Other controlling parameters include combustion chamber pressure (sensor 36), temperature and humidity in the intake pipe 8 (sensor 37), smoke and/or temperature in the exhaust pipe 9 (sensor 38), and the positions of the inlet and exhaust valves (sensors 30). In a modification, Fig. 2 (not shown), the valves biasing springs 29 are omitted and pressure fluid is applied to both sides of the controlling pistons 21. In a further embodiment, Figs. 3 and 4 (not shown), operation of the inlet and exhaust valves is mechanical, via the usual cam-shaft, tappet, pushrod and rocker arm. However the phase of the crank-shaft and cam-shaft is variable by adjusting the chain guide between the crank-shaft and cam-shaft under control of the controller 12. Also, the longitudinal position of the cam-shaft may be adjustible, again under control of the controller 12.
