FUEL INJECTION TIMING CONTROL DEVICE FOR INDEPENDENT INJECTION TYPE INTERNAL-COMBUSTION ENGINE

摘要

PURPOSE:To such all of injected fuel in suction stroke by a method wherein injection starting timing is advanced by the amount of increased fuel based on the condition of warming-up, acceleration or the like. CONSTITUTION:The basic fuel injection amount taup of respective cylinders is operated in a basic fuel injection amount operating means 1 in accordance with first predetermined operation condition parameter and a last injection amount tau is operated in a last injection amount operating means 2 in accordance with the second predetermined operating condition parameter of the engine. The last injection amount tau is compared with the basic injection amount taup by a comparating means 3. On the other hand, the fuel injection starting timing of respective cylinders are operated in an injection starting timing operating means 4 in accordance with the third predetermined operating condition parameter. As a result, the injection starting timing is advanced by a time in accordance with difference between the last injection amount tau and the basic injection amount taup by an injection starting timing advancing means 5 when the last injection amount tau the basic injection amount taup. Fuel injection finishing timing is operated by an injection finishing timing operating means 6 in accordance with the operated or advanced injected starting timing and the last injection amount and, thus, the fuel injection is effected.
