Introduction and Explanation of power rating of the WD164 Serial Diesel Engine

- Jan 22, 2018-

1.Diesel engine introduction

WD164 series diesel engines are, four strokes, direct injection and water-cooling high speed diesel engine. The style of intake is turbocharged air-air cooling and turbocharged water-air cooling. They are widely used in the field of diesel engine generator, agricultural irrigation, construction machinery, emergency fire protection pump and industry.

Diesel engine uses the integrated crankshaft, the body for gantry structure, cylinder head for one cylinder and one cap, each cylinder head has two inlet valves and two exhaust valves, fuel injectors are located in the center of the cylinder. Power is output from the flywheel end. Therefore, suitable power take-offs and necessary accessories must be attached to the engine before it can be properly used. Connection of the output end is SAE type and can also be modified to resilient coupling. Cylinder number designation of WD164 series diesel engine: The cylinder number is 1-6 counted from the free end to the flywheel end . Our product is designed in the principle of series, standard, general, so that the main components can be exchanged.


2.Explanation of power rating

The power rating of WD series diesel engines is the permissible effective power output for the engine with the air cleaner, but without other accessories which will affect its running such as fan, muffler, coupler, and gear box etc. to operate under the atmospheric condition of 100kPa (750mmHg) barometric pressure, 25℃ ambient temperature and 30% relative humidity. The engine can also be overloaded at 110% of the 12 hour power rating for a short period of not over 1 hour discontinuously or continuously during each 12 hour operation.

Output power of the diesel engine that the nameplate indicates includes the power the fan has consumed when running with the fan but the output power of engine (effective power) should deduct the power the fan consumes 15KW.

Because the output power will decrease with altitude, ambient temperature and relative humidity increasing of the using area, so the customer should correct the rated power according to the correcting method of standard GB/T6072.1 when the barometric pressure, ambient temperature or relative humidity is different from the above stated standard atmospheric condition.
