| Abstract: | A WP10.336 diesel engine was changed into a dual fuel engine, calibrated and tested. The test results show that the power performance of the dual fuel engine is equivalent to that of the original diesel engine, and the average diesel replacement rate reaches 95.7% observed from the external characteristic curve. The dual-fuel engine has been shown to achieve higher thermal efficiency and the diesel replacement rate at 1 200 r/min under medium and high loads. The maximum combustion pressure corresponding to the maximum power output point is 14.82 MPa. |
