DEVICE AND METHOD FOR ENGINE STARTING IN GASOLINE CNG- COMBINED CARGO WORK VEHICLE

摘要

PROBLEM TO BE SOLVED: To perform the start of high quality without changing the layout in an engine room. SOLUTION: A bypass 25 is formed between a low pressure reducing valve 11 and a carburetor 4, a bypass solenoid valve 26 is mounted on the bypass 25, and the bypass solenoid valve 26 is connected to a key switch 28 to open the bypass solenoid valve 26 by the key switch 28 for a predetermined time from the start of a gasoline engine 3. As a result, a distance of a gas supply passage from the low-pressure reducing valve 11 to the carburetor 4 is shortened in comparison with a conventional distance through a mixer 14. As a time to the start of the gasoline engine 3 is shortened, the start of high quality is achieved without changing the layout in the engine room 2.
