DUAL FUEL INJECTION SYSTEM INTERNAL COMBUSTION ENGINE |
摘要 |
To simply prevent an internal combustion engine including PFI and DI injectors from generating of knocking phenomenon, the internal combustion engine includes an engine control unit (ECU) for setting a ratio of fuel injection quantity of both the injectors (Step S2). The ECU includes a memory storing four sheets of ignition timing maps, with reference to which the maximum torque generation timing and knocking limit torque generation timing, at the direct injection injector (100%) and port fuel injection injector (100%), are calculated (Step S3). The ECU further operates to calculate a correction amount from correction amount map (Step S4). The ECU calculates first interpolation value of the maximum torque generation timing at the above 100% operation time of both the injectors and second interpolation value of the knocking limit torque generation timing at the above 100% operation time of both the injectors, and a value in which the correction amount is added to either one of the above first and second interpolation value on a delay angle side is calculated as ignition timing (Step S5). |
