Main Structural Features of Natural Gas Engine - Weichai WP13NG Gas Generator


1.1 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.

What Is the Difference Between Electric Motor and Electric Generator

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and winding currents to generate force. In certain applications, such as in regenerative braking with traction motors, electric motors can be used in reverse as generators to recover energy that might otherwise be lost as heat and friction. An electric generator operates in the reverse direction, converting mechanical energy into electrical energy. Electric generator can be divided into various type, open type, silent type, trailer type, portable type and container type, etc. Electric generator is mainly composed of diesel engine & alternator. Electric generator set is mainly composed of engine, alternator, control module, and common base. Electric generator :- Electric generator is a type of machine which converts mechanical input (energy) into electrical output (...
