Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as Figure 1~2 As shown, the CNG engine single-cylinder self-inflating system designed by the present invention includes a CNG engine, a high-pressure CNG storage tank 2, a pressurized storage tank group and a connecting pipe network, and the CNG engine includes a cylinder and an ECU. The CNG engine is a six-cylinder engine, wherein one cylinder is refitted as the charging cylinder 4, and the other five cylinders remain unchanged as the power cylinder 41.

[0031] Each cylinder is respectively provided with a cylinder intake valve 42, a cylinder exhaust valve 43, a cylinder head 44, a spark plug 45, a connecting rod 46, a piston 47 and a crankshaft 48. The cylinder head 44 of the inflation cylinder 4 is provided with an inflation channel 5 , and a cylinder closing device 6 is arranged near the cam of the inflation cylinde...

Abstract

The invention discloses a self-inflating method for a single cylinder of a CNG engine. By taking one air cylinder in the CNG engine as an inflating air cylinder and part of or all the rest of air cylinders as power air cylinders, the inflating air cylinder is taken as a piston compressor air cylinder to inflate compressed civil natural gas into a high pressure CNG storage tank. The invention discloses a self-inflating system for the single cylinder of the CNG engine at the same time. The system comprises the CNG engine, the high pressure CNG storage tank and a connecting pipe network; the CNG engine comprises the air cylinders and an ECU, wherein each air cylinder comprises an air cylinder inlet valve, an air cylinder outlet valve, an air cylinder cover and a sparking plug; the air cylinders comprise one inflating air cylinder and at least one power air cylinder; and the inflating air cylinder is provided with an air cylinder closing device and an inflating channel, an inflating pipe is arranged on the inflating channel, and an air cylinder inflating control valve is arranged on the inflating pipe. By means of the method and system, a CNG automobile can be filled with civil natural gas, the modification extent is small, the method and system are easy to realize, and the property of the CNG engine is not affected.

Description

technical field [0001] The invention relates to a CNG vehicle, in particular to a CNG engine single-cylinder self-inflating system and a self-inflating method thereof. Background technique [0002] As a recognized clean energy, natural gas is listed as the three pillars of world energy alongside coal and oil. Due to the dwindling of oil resources, in order to alleviate the concerns of automobiles on the durability and durability of oil resources, hybrid vehicles such as gasoline and electricity, gasoline and natural gas have been developed and put into use. In recent years, the state has introduced some policies to support the development of the natural gas industry, encouraging and supporting vehicles and ships fueled by LNG and CNG. [0003] my country's natural gas resources are mainly concentrated in the west and offshore areas. On the one hand, cities near the gas source, such as Sichuan, Chongqing, Urumqi, Hainan, etc., have a large number of built gas filling station...
