Problems solved by technology

[0002] At present, in the industry, the installation position of the oil stop solenoid valve of the fuel injection pump of the twin-cylinder connected diesel engine is in a straight line with the oil supply ports of the left and right cylinders, and the low oil pressure chamber is very large, resulting in about 20 seconds of idle shutdown. There is no such valve in the industry. The fuel inlet port of the fuel injection pump and the fuel stop solenoid valve are designed at the side

Embodiment Construction

[0009] Below in conjunction with accompanying drawing, specific embodiment of the present invention is elaborated:

[0010] An oil stop solenoid valve for a fuel injection pump of a two-cylinder conjoined engine, comprising an oil pump body 1, an oil volume control rack 2 installed on one side of the oil pump body 1, an oil stop electromagnetic valve 5 and an oil pump inlet 6 installed on one side of the oil pump body 1, The oil stop solenoid valve 5 and the oil pump inlet 6 are installed on the same side or the other side of the oil volume control rack 2, and the oil supply port 3 of the right cylinder and the oil supply port 4 of the left cylinder are installed above the oil pump body 1. When the engine is turned off and the start switch , the fuel stop electromagnetic valve 5 works, and now the engine oil supply volume is smaller than that of the conventional oil pump, thereby shortening the downtime.

[0011] The above is only a preferred embodiment of the present inventio...

Abstract

The invention discloses an oil stop electromagnetic valve for an oil injection pump of a double-cylinder one-piece engine, which comprises an oil pump body. An oil quantity control rack is arranged at one side of the oil pump body; an oil stop electromagnetic valve and an oil-pump oil inlet are arranged at one side of the oil pump body; and the upper part of the oil pump body is provided with a right cylinder oil supply port and a left cylinder oil supply port. The invention provides the oil stop electromagnetic valve for the oil injection pump of the double-cylinder one-piece engine; the oil inlet of the oil injection pump and the oil stop electromagnetic valve are arranged at the side of the oil injection pump; installation of a product is not influenced at all; batch production can be implemented; the volume of a low-pressure cavity of the oil injection pump of the double-cylinder one-piece engine is reduced; idling and stop time of the engine can be reduced within the range of 5s; and the requirements of clients are greatly met.

Description

technical field [0001] The patent of the present invention relates to the technical field of diesel engines, in particular to a solenoid valve for shutting down fuel injection pumps of two-cylinder conjoined engines. Background technique [0002] At present, in the industry, the installation position of the oil stop solenoid valve of the fuel injection pump of the twin-cylinder connected diesel engine is in a straight line with the oil supply ports of the left and right cylinders, and the low oil pressure chamber is very large, resulting in about 20 seconds of idle shutdown. There is no such valve in the industry. The oil inlet port of the fuel injection pump and the fuel stop solenoid valve are designed on the side. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to provide a fuel injection pump fuel stop solenoid valve with fast shutdown in order to make up for the deficiencies of the prior art. [0004] The technical scheme ...
