GAS ENGINE
Document Type and Number:
Japanese Patent JP2015227634
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a gas engine capable of properly avoiding occurrence of knocking.SOLUTION: When an excess air ratio is controlled to be within a stoichiometric range, a throttle opening control part performs first control to control the opening of an intake throttle valve so that an output shaft rotates at first constant rotational frequency when it is determined that a torque value is equal to or less than A[Nm]; also, when it is determined that the torque value is larger than A[Nm], performs second control to control the opening of the intake throttle valve so that the rotational frequency of the output shaft is made larger.
