| 摘要： | 本发明公开了一种CNG发动机单缸自充气方法，通过将CNG发动机内的一个气缸作为充气气缸，余下的部分或全部气缸作为动力气缸，使充气气缸作为活塞式压缩机气缸，将民用天然气压缩后充入高压CNG储罐内。本发明同时公开了一种CNG发动机单缸自充气系统，包括CNG发动机、高压CNG储罐和连接管网；所述CNG发动机包括气缸和ECU，所述气缸包括气缸进气阀、气缸排气阀、气缸盖和火花塞；所述气缸包括一个充气气缸和至少一个动力气缸；所述充气气缸设置有闭缸装置和充气通道，所述充气通道上设置有充气管，所述充气管上设置有气缸充气控制阀。该方法和装置能够使用民用天然气对CNG汽车进行充气，改装幅度小，易于实现，不影响CNG发动机的性能。 | ||
| 摘要(英文)： | The invention discloses a self-inflating method for single-cylinder engine CNG, CNG engine through one of the cylinder is used as a pneumatic cylinder, the remaining part or all of a cylinder as a power cylinder, the pneumatic cylinder is used as a piston compressor cylinder, after compression the civil natural gas in the storage tank filled with high-pressure CNG. At the same time, the invention discloses a self-inflating system CNG single-cylinder engine, comprises a CNG engine, high-pressure CNG storage tank and the connection pipe network; the CNG engine comprises a cylinder and said ECU, the cylinder includes a cylinder intake valve, the exhaust valve of the cylinder, cylinder head and spark plug; the cylinder comprises a pneumatic cylinder and the at least one power cylinder; said inflatable cylinder is provided with a closed device and inflatable channel, the inflation channel is provided with an inflatable tube, the charging of the cylinder pipe is provided with pneumatic control valve. The method and device can use the civil natural gas to inflate automobile CNG, modified amplitude is small, it is easy to realize, CNG is not affected the performance of the engine. | ||
