【Abstract】 This paper introduces briefly the structure of bench test and measurement system for spark-ignition coal-bed gas engine, and describes in detail measurement principle of several main parameters. Some of results are given. The measurement system meets the needs of bench test relatively well, and is essential to study operation characteristics of the engine with change of concentration of components in coal-bed gas, and to collect control data used by ECU.更多还原
