| Abstract: |
| An electronically controlled gas fuel injection device was presented aiming at the disadvantage of backfire and fuel loss of heavy-duty gas engine. The multiple-point sequential and intermittent fuel injection was achieved. The engine test-bed was developed to test the engine start performance and idle stability. The uniformity control of each cylinder and load changing were also tested. The experimental results show that the gas fuel mass can be independently controlled by electronically controlled injection device. The engine runs smoothly and the feasibility of the technology was verified. Furthermore, with the application of electronically controlled injection device, the performance of the engine can be improved by increasing the scavenging overlap angle and the compression ratio. |
