摘要：
A design scheme was presented for refitting a NJG427 engine into a gas-fuel engine of electronically controlled multi-point injection, which included optimization and improvement on fuel system, ignition system, intake system and exhaust system, increasing in compression ratio, and design on electronic control unit. The refitted engine was tested on an engine test bench subsequently. Results indicated that the refitted engine's power performance came back, economy performance became better, and emission level measured up to the third-stage emission standard of Europe.
