We developed a diesel engine cylinder test facility to carry out fatigue lest of engine head by controlling hydraulic pulsating pressure up to 100 Hz. Using a high-pressure pump up to 30 MPa, high pressure servo valves and pressure sensors, a cylinder head fatigue can be performed. This engine head facility can perform a head fatigue lest by 6 times faster than a normal engine durability test whose test time takes usually more than one month. We tested 3 different types of diesel engine heads developed by HMC. The results of fatigue tests show absolutely identical cracks occurred by the engine durability test. By using this diesel engine head fatigue test facility, we can find the fatigue crack positions of newly developed engine cylinder head, shorten developing time of engine cylinder head and design a robust engine cylinder head.
