ELECTRONIC
CONTROLLED HIGH-
ENERGY DIRECT IGNITION SYSTEM
FOR TURBOCHARGED CNG ENGINE*
Abstract: Nowadays the research and development of CNG engine is coming into a hotspot in engine industry of China. Because of the specific character of turbo-charged CNG engine, the ignition needs more energy than petrol engine. The hardware and software of electronic controlled high-energy direct ignition system (ECHDIS)
based on microprocessor used in turbo-charged natural gas engine
are described, the simulation results of the ignition circuit in
the design of system which is used to instruct the design of the system are also given out. The experiment results show that the system reach the requirement, the result of ignition energy is according to the simulation result.
Key words:
Turbo-charged natural gas engine Electronic control High-energy Ignition system simulation
