摘要： PROBLEM TO BE SOLVED: To suppress the knocking of an engine and improve the efficiency of the engine by providing a control engine, in addition to a main engine for taking fuel and oxygen-containing gas and burning them to generate a power, and supplying the exhaust gas of the control engine into the main engine. SOLUTION: In addition to a main engine (4-cylinder engine) 100, a control engine 10 is provided to drive a cooling water pump by the rotating power of the crankshaft 16 of the control engine 10. As the control engine 10, a compression self-ignition engine is adapted, and the intake air [air-fuel mixture of fuel and oxygen-containing gas (including air)] 20 sucked through an intake passage 19 is compressed and self-ignited by a piston 14. The control exhaust gas after combustion is discharged to an exhaust gas passage 11 and distributed to each cylinder 1 of the main engine 100. At this time, the operating condition of the control engine 10 is set so that formaldehyde of unburned component is included in the control exhaust gas 22.

摘要： PURPOSE: To establish effective utilization of a fuel by controlling the revolving speeds of a plurality of engines, which share the power dispersedly, individually so that the rate of fuel consumption minimizes according to the load which the train requires. CONSTITUTION: The control line includes a main control device 8 and a dispersive control device 9 for each of a plurality of engines. The main control device 8 is fed with a command of a trunk controller 6 for the engine control and the conditions of a velocity type power generator 10 and the applicable engine (the condition of the engine to be fed through a communication line 11) and judges which engine should be operated with how heavy a load. The command applicable is transmitted to the dispersive control device 9 through the communication line 11. That control device 9 which has received the command gives specified commands to a solenoid valve 5 for controlling a liquid type transmission and a fuel control device 4. The control command is made to the engines individually upon judging the size of the power which the train requires at that time to be passed upon the rail-car train total basis.
