Title:
CONTROLLER OF GAS ENGINE
Document Type and Number:
Japanese Patent JP3500047
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent the over concentration of gas, to prevent the generation of misfire and knocking, and to stably start, by comprising a governor controller which can change a limiting value of a fuel gas flow corresponding to the engine speed through a governor actuator and a gas flow adjusting valve at the start of the engine.
SOLUTION: The engine speed is detected by a rotation detector 5, and is input to a engine speed comparing part 11 of a governor controller 10. In the engine speed comparing part 11, the detected engine speed and an intermediate engine speed are compared, and the result of the comparison is output to a governor output increase and decrease ratio changing part 13. The detected engine speed is compared with the predetermined intermediate engine speed, and the output of the governor actuator is changed into the increase and decrease ratio of the governor actuator output corresponding to the change of the engine speed. A command from the governor output increase and decrease ratio changing part 13, is sent to a governor actuator 21 through an actuator manipulated variable computing part 15, for adjusting the opening of a gas flow adjusting valve 4. Whereby the generation of a misfire and knocking can be prevented.
