摘要

Diesel engines can be supplied with both fuel oil and fuel gas by high pressure injection. Each of the combustion in the cylinder 29 of the engine is initiated by the injection of fuel oil, and the gas may be injected after the start of combustion. The ratio of the gas in the total fuel amount per combustion is adjustable and the gas injection is prevented by the safety device 16 in the event that fuel oil can not be injected. When the ratio of the gas in the total fuel amount at a constant engine load is changed, the start time for injecting the fuel gas with respect to the start time for injecting the fuel oil is changed, whereby the gas injection is delayed. In this case, And the gas injection is accelerated when the ratio of the gas in the total fuel amount becomes larger.
