The major parts of this series engine and original engine are universal and the high reliability of original engine has been retained. The emission data can meet Euro III standard. WT615 Turbocharged and Inter-cooled CNG Engine Lean mixture combustion technique, electronic high-energy ignition, multipoint sequential injection and electronic control gas supply have been adapted on the basis of WD615 turbocharged and inter-cooled diesel engine. The major parts of this engine and original diesel engine are universal, and the mounting dimensions are the same. The emission meets Euro III standard.
