Performance Evaluation of 12Hp 4-stroke Single Cylinder Diesel Engine based on the Philippine Standards

Presently, local demands for single cylinder engines used in agricultural equipment served thru importation. Our country is in complete dependence on other countries concerning supplying the prime movers for its primary source of power. The Department of Science and Technology initiated developing a 12Hp single cylinder diesel engine. And to make it acceptable to the user, performance evaluation of engine was conducted as necessary for their commercial operation. PAES 117:2000 is the basis of assessing the engine performance and tested at starting condition, varying load performance and during a continuous run. Based on the result, the average maximum power was rated 93.9% (8.42 kW). Likewise, the average fuel consumption was 3.15 L/hr. Also, the average continuous power as a percentage of the rated maximum power was 83.6% (7.48 kW). During the continuous running test, the average maximum noise level of the prototypes was 90.6 dB(A). It showed that the engine developed achieved the standard performance conditions and comparable to the leading brands of commercial engines of the same power rating.
