Abstract:

Article Preview

According to the requirements of heavy commercial compressed natural gas (CNG) vehicle to satisfy China’s rapid economic development, the authors develop and test a new high energy direct ignition system of heavy CNG engine. Hardware and software of the high energy direct ignition system are designed and debugged. Based on the tradition test bench, an optimal test bench for this CNG engine is established. Ignition advance angle is calibrated and analyzed, which has the economy and power performances effects on CNG engine matched the developed high energy direct ignition system. To test the effects on engine emissions by high energy direct ignition system, ignition control strategy is simplified and optimized. In addition, high ignition energy is directly determined by current time of ignition coil power. A test study about torque, power and fuel consumption of this engine is accomplished. The final test results indicate that this developed high energy ignition direct system can satisfy the comprehensive performance objectives of heavy CNG engine.
