    Abstract: Problems resulting from engine research and development are found during target performance test.Based on principles of internal combustion engine and fluid dynamics,combined with analysis of test behavior,the ensuing research test finds that the problem results from large pressure fluctuation in intake pipes.An improved proposal is made on this basis and the engine performance is optimized.

    Keywords: Diesel Engine;Performance Test;Research Test;Intake Pressure
