Abstract
PURPOSE: To have a smooth transition from start to warming-up of an EFI engine and thereby prevent engine stop etc. by reducing the amount of injection fuel for start by steps.
CONSTITUTION: The relation between the temperature at the time of starting, TE, and the increase factor of the starting fuel, n, is stored in No.1 memory , while the reference fuel injection time Ti set with parameters suh as number of revolution Ne and throttle opening θth is stored in No.2 memory 3, and further the relation between temperature at the time of warming-up, TE, and the increase factor m of the warm-up fuel, is stored in No.3 memory, and they are sent to multiplier devices 2, 11. Signals sent into the multiplier 2 are put into a preset down counter 4 fed with clock ck, and further while being reduced with its count sent 10 a flipflop 6 controlling the injection solenoid. Signals from the multiplier 11, on the other hand, are put into a high-value selector 9 together with the signals from preset down counter 8, and the high value signal is forwarded to the counter 4.
