摘要： A fuel supply method for a gas engine and an injection control apparatus of gas fuel substituting for gasoline are provided to achieve fuel injection control with proper injection timing by injecting the gas fuel using corrected delay time. A fuel supply method for a gas engine comprises a step of performing injection control of the gas fuel by using a plug representing if the gas fuel is injecting or is not injecting. When the plug represents that the gas fuel is not injecting at the time point at which injection start of a gasoline injection signal is detected, injection of the gas fuel starts by setting the plug representing that the gas fuel is injecting. When the plug represents that the gas fuel is injecting at the time point at which injection end of the gas fuel is detected, the plug representing that the gas fuel is not injecting is set.

摘要： An air/fuel ratio correction cylinder determining section 25 specifies, based on the peak phase, a cylinder for which an air/fuel ratio is to be corrected. A cylinder-specific air/fuel ratio correcting section in the form of respective cylinder correcting sections 31 through 34 corrects an amount of fuel to be supplied to a cylinder which becomes an air/fuel ratio correction target. A cylinder for which an air/fuel ratio deviates from the remaining cylinders is specified as a fuel amount correction target based on a change in the output value of the air/fuel ratio sensor.

摘要： In a direct injection type engine, capable of switching an injection mode between a compression stroke injection mode for injecting fuel mainly during a compression stroke and an intake stroke injection mode for injecting fuel mainly during an intake stroke; a fuel injection starting timing in the intake stroke is corrected to a retard side as the temperature relating to an internal combustion engine, detected as a parameter representing the tendency of fuel to adhere to the inside of the internal combustion engine, becomes lower. If a required fuel injection volume cannot be injected during the intake stroke injection mode in the corrected fuel injection timing, a timing for injecting remaining fuel to satisfy the required fuel injection volume during a compression stroke following the intake stroke in one combustion cycle is determined. The injection of the fuel is controlled according to the corrected fuel injection timing.
