Title: Fuel injection control for IC engine - has time delay circuit fed from temp. indicator for cold starting
Inventor: BERTSCH RICHARD
IPC: F02D41/34
Filed: 1978-04-05
Abstract: An airflow meter(10) in the engine suction and a tachometer(11) provide inputs to an impulse generator(13). The output of this is fed into a correcting stage(15) into which the signals from the meters are also fed directly. The corrected output(18) drives the fuel injection valves(19). An engine temp. detector(12) provides a further input to the correcting stage. This input feeds a time delay circuit within the correcting stage so that the injection valves are opened for a longer period when the engine is cold. This compensates for fuel condensation in a cold engine without increasing the mixt. strength.
