The power range of D series diesel engine matched with generator set is from 20.6-44KW. In order to meet the needs for two difference frequencies 50Hz and 60Hz of generator set, the rated speed can be either at 1500r/min or and 1800r/min. 495BD generator set is a modified version of Model 495B Diesel engine which has been awarded continuously the National Golden Medal prize thrice.
There are two kinds of air feeding of diesel engine, natural aspirated and turbocharger type, and the connecting dimensions of output end are in compliance with IMB34 international standard or SAE standard. This engine can be equipment additionally with temperature pressure, speed sensors and special design can be performed according to the customer's requirement.
