また、バルブへのなじみ性と高温強度を両立し、ガイドの欠けやクラックの発生を抑えました。 Roles of valve guide are maintenance of the valve and diffusing heat of the valve to the outside. High intensity, heat conduction, wear resistance, and so on is asked for the quality of the material.
However, the sintered material that is used in various parts of the stock engine, is giving priority to the cost and a work environment of production factory, and is unsuitable for the material of the tuning engine that uses high rotation and high load regularly. The phosphor bronze valve guide of TOMEI can efficiently diffuse the heat of the valve to the cylinder head with its high heat conduction. Moreover, both familiarity to the valve and high temperature intensity are achieved, while chip or crack of the guide were suppressed.
