by Starlight Generator dieselgeneratortech

WP13NG series natural gas engine for power generation is made by improving the previous Weichai WP6/WP4 series diesel engine for power generation through removing of engine fuel system and adding of gas supply system and relevant devices. This natural gas engine is characterized by compact structure, reliable operation, excellent technical performances in reliability, power, economical efficiency and exhaust emission, quick start-up, easy operation and least maintenance, etc. It has already become a new power source of power generation equipment and is frequently used as a main or standby power source in coal mine, oil field, farm, gas station and other places. In addition, it can be fueled by natural gas, methane and biomass gas, etc.

This manual briefly introduces the technical parameters, performance indicators, structural features and usage & maintenance precautions of WP13NG series natural gas generator. The user shall comply with various specifications stipulated in this manual when using this natural gas engine.

This manual deals with the basic model WP13NG series stand-alone natural gas generator. As the product structure is improving as the product develops continuously, this operating manual may lag behind such improvement.

Main structural features of natural gas engine

● A cover per cylinder, dependable operation, easy disassembly.

● Frame-type main bearing structure and high complete machine rigidity which benefits the reliability and service life of complete machine.

● Electronic throttle is adopted to control engine revolving speed.

● Mixture supply system uses mixer to regulate air-fuel ratio and adopts proportional mix and supercharged inter-cooling method to stabilize gas supply.

● Water-cooling middle case turbocharger applicable to gas engine features is selected and circulating water shall be used to cool down turbocharger lubrication cooling oil so as to effectively prevent pressure bearing lubricating oil from coking and to improve turbocharger’s reliability.

● Designed gas mixing system satisfies gas fuel features to effectively support stable lean burn and enhance thermal efficiency.

● Two pairs of friction couples of inlet, outlet valves and valve seats shall be made of materials fit for gas engine’s operating characteristics so as to ensure high temperature abrasive resistance property and excellent self-lubrication performance.
