Gas system main parts technical & installation requirements 1. Pressure reducer Installation requirements ●  Pressure reducer is a supplied accessory and shall be mounted in places with little vibration and near to the engine with distance not exceeding 2m. ●  It shall be installed behind the filter and installation position shall be convenient for regular adjustment, inspection and maintenance of pressure reducer. ●  Pipeline connecting to pressure reducer shall be reasonably arranged and free from interferences. ●  Pressure reducer gas outlet and the bottom shall not be upward to prevent fuel gas greasy dirt from back flowing into pressure reducer. ●  Screw off the top cap and adjust the screw to pressure reducer valve, turn clockwise to thicken and anticlockwise to thin (Note: such mode of regulation is only applicable to high speed regulation). 2. Low pressure gas filter Installation requirements: ●  Gas filter installatio...

1. Operation and maintenance of air filter Warning! The service life of your engine may be shortened greatly due to wrong maintenance methods. 1. The  air filter  shall match the performance index of engine in a strict way; otherwise, the dynamic property and  economy performance of engine will be influenced. 2. If the air filter is provided with a warning device, the warning device shall be observed first before the natural  gas engine is started. When the intake resistance indicator give an alarm (turns red), the air filter element shall be  maintained. 3. The filter adopting multistage filtration technology must be provided with a coarse strainer. 4. When mounting the dust exhausting pipe, the pipe shall not be bend sharply and shall be free from air leakage. 5. Prevent water from entering into the air filter. 6. When maintaining an air filter with a safety filter element, do not disassemble the safety filter element. 7. In normal working con...

3.1 Unpacking of natural gas engines After unpacking the natural gas engine , the user shall count the engine and its accessories first in accordance with the packing list. After that, the user shall check the engine appearance for damage and the connecting pieces for looseness, and complete the following works: ◆ Wipe the antirust coat and corrosion inhibitor on the exposed parts; ◆ If the oil pan is not filled with oil, according to the agreement between the manufacturer and the user, fill oil into it. If the oil pan is filled with engine oil containing running-in accelerating agent before leaving our factory, we suggest that the user drain off the old oil and replace with new oil after 50 hours of trial operation. ◆ If the engine is filled with coolant before leaving our factory based on the user needs, according to the agreement between the manufacturer and the user, the user shall check the performance of coolant after unpacking the engine. The coolant is usable...

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, outl...

Special Instructions for WEICHAI WP13NG Series Gas Generators ● Before operating a natural gas engine, the operator must read this operation and maintenance manual carefully and follow the operation and maintenance procedures specified in this manual in a strict way. ● This natural gas engine has undergone factory inspection according to the test specifications in a strict way.
