Embodiment Construction

[0012] see figure 1 , a kind of CNG debugging method based on LNG engine that the present invention relates to is applicable to the vehicles such as coach, bus, and its concrete structure is:

[0013] Including CNG gas cylinder 1, CNG gas cylinder 1 is connected with high-pressure strainer 3 through high-pressure pipeline 2, and high-pressure strainer 3 is connected with high-pressure reducer 4 through high-pressure pipeline 2; 5 Connect with engine mixer. The high pressure reducer 4 has the function of connecting the engine to the circulating water heating, and the high pressure reducer 4 connects the circulating hot water from the engine to prevent freezing. The high-pressure reducer 4 is connected with the engine mixer through a Φ14 polyamide pipe.

[0014] The CNG gas cylinder 1 in the present invention can specifically be a steel cylinder.

[0015] The key points of the technical solution of the present invention are: the gas source is CNG, which is filtered and decomp...

Abstract

The invention relates to a compressed natural gas (CNG) adjusting method based on a liquefied natural gas (LNG) engine. The CNG adjusting method based on the LNG engine comprises a CNG gas bottle which is connected with a high pressure coarse strainer through a high pressure pipeline, the high pressure coarse strainer is connected with a high pressure reducer through the high pressure pipeline, and the high pressure reducer is connected with an engine mixer through a polyamide tube. The CNG adjusting method based on the LNG engine has the advantage of being convenient and flexible to arrange.

Description

technical field [0001] The invention relates to a CNG debugging method based on an LNG engine. Background technique [0002] Among the chassis products supplied by chassis manufacturers to Shanghai Automobile Plants, LNG and CNG engines each account for a large proportion. However, some LNG gas supply methods are often purchased and arranged by the car factory itself, which brings great inconvenience to the debugging and ignition of the chassis factory. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a CNG debugging method based on an LNG engine to overcome the defects in the prior art. [0004] The technical solution of the present invention is: a CNG debugging method based on an LNG engine, which is characterized in that it includes a CNG cylinder, the CNG cylinder is connected with a high-pressure strainer through a high-pressure pipeline, and the high-pressure strainer is connected with a high-pressure re...
