    摘要： An improved injection system for a dual-fuel Diesel engine operated by means of main fuel having a low cetane number and auxiliary fuel having a high cetane number, is disclosed herein. The improvements reside in that the injection system comprises a pressure regulating check valve (7) provided in parallel to a delivery valve (6) in a main fuel injection pump (3) and allowing only a fuel flow in the opposite direction to that in the delivery valve, a control valve (16) for feeding the auxiliary fuel pressurized by a fuel feed pump (18) to a fuel injection valve (9) at an appro­priate feed rate and at appropriate fuel feed timing with the aid of a control device (20), and a check valve (13) provided in the proximity of a fuel reservoir (12) of the fuel injection valve (9) in a flow passageway of the auxiliary fuel.
