Abstract: An integrative control method and device for controlling gas engines is proposed which is improved load responsivity of the engine while maintaining air fuel ratio control. The control method comprises a speed control process for controlling engine rotation speed by calculating a command value of fuel gas flow rate based on deviation of a detected engine rotation speed from a target command value of engine rotation speed and controlling fuel gas flow rate flowing through the fuel gas flow control valve to coincide with the calculated command value of fuel gas flow rate, and an air fuel ratio control process for controlling air fuel ratio of fuel-air mixture supplied to the combustion chamber of the engine through performing feedback control in which such a command value of fuel-air mixture flow rate is calculated that air fuel ratio of the mixture is appropriate with the fuel gas flow flowing at the commanded fuel gas flow rate and a target opening of the throttle valve is determined based on deviation of the actual mixture flow rate calculated based on detected values of operating conditions of the gas engine from the calculated command value of fuel-air mixture flow rate.

Abstract: An engine controller performs low opening degree control during a first intake stroke period since an engine start is commenced until first intake strokes of respective cylinders end. Thus, an opening degree of an intake throttle valve is controlled to a fully closed position or proximity of the fully closed position such that intake pressure downstream of the intake throttle valve becomes equal to or lower than critical pressure with respect to intake pressure upstream of the intake throttle valve during an intake stroke of each cylinder. The controller calculates a leak air quantity at the time when the intake throttle valve is fully closed based on an intake air quantity sensed during the low opening degree control. The controller corrects a feedback gain of idle speed control in accordance with the leak air quantity of the intake throttle valve.

Abstract: A straddle-type vehicle includes an engine, an air intake pipe, a throttle valve being controlled in accordance with an operation amount of an accelerator grip, an engine rotating speed detector or a vehicle speed detector, and an electronic control unit (ECU). The ECU increases the opening degree of the throttle valve or maintains the opening degree at a constant value until the engine rotating speed reaches a set rotating speed which is smaller than a prescribed rotating speed, but if the engine rotating speed exceeds the set rotating speed, the ECU reduces the opening degree of the throttle valve irrespective of operation of the accelerator grip.
