FUEL CONTROL METHOD AND DEVICE FOR COMBINED FUEL DIESEL ENGINE

摘要

PURPOSE:To enhance an effective utilization factor of energy even if a supply quantity of fuel substantially changes, by controlling fuel distribution of a multi cylinder combined fuel Diesel engine by a cylinder unit. CONSTITUTION:An engine provides oil pumps 11, gas valve control oil pumps 12 and exhaust valve control oil pumps 13 to be lined corresponding to each cylinder. The engine detachably engages control shafts 14 of the oil pumps 11 with an oil distribution control shaft 21 through arms 16 while control shafts 15 of the pumps 12 with a gas distribution control shaft 22 through arms 17. While the oil distribution control shaft 21 and the gas distribution control shaft 22 are connected with a governor output shaft 25 through a fuel distribution means 24. And the engine detaches the arms 16 from the control shaft 21 to be engaged with a single fuel control shaft 23 while the control shaft 15 from the control shaft 22 to be returned to a zero position if a supply quantity of gas decreases.
