The invention relates to a rapid wear test system in the power machinery filed, aiming to provide a rapid wear test system of valves and seat rings used for internal combustion engines. The system comprises a motor and a camshaft connected with each other by a coupling and also comprises valves on cylinder heads and valve seat rings arranged between the valves and the cylinder heads. Valve stems of the valves pass through the cylinder heads and are provided with valve springs and spring seat rings in a mating manner. The system is characterized in that a combustor is arranged above the valvesand the spring seat rings are connected with the camshaft by a tappet. The system of the invention is convenient to control and easy and feasible and greatly improves the convenience of operation andsafety during long-time running. The whole set of test system is compact in structure, convenient to operate, small in floor area and flexible in arrangement.
