Experiment Study of the Single Point And Multi-Point Natural Gas Electronic Injection Systems

摘要

To compare and improve diesel engine emission performance by different injection methods, a multi-point natural gas in-system and a one-point injection system were developed. In both systems, the electromagnetic valves are used to control injection and total quantity. The system was designed for the type X6130 diesel engine. The test results showed that the multi-point system has great advantages in the aspects of emissions. To adopt multi-point gas injection is a better way to reduce the emission.
