为了提高汽车发动机的功率,目前正逐渐重视提高其耐热性和耐磨性的研究。日本松田汽车公司研制成功将铝活塞的第一道气环沟槽用镍系金属泡沫铸造形成一体的“镍泡沫复合活塞”技术,为提高发动机的功率和扭矩迈出了新的一步。该活塞已经在装有涡轮冷却的重型载货 In order to improve the car engine power, is gradually increasing emphasis on improving its heat resistance and wear resistance of the study. Japan’s Matsuda Motor Corporation successfully developed the first gas ring groove of the aluminum piston with nickel-based metal foam casting to form a “nickel foam composite piston” technology, to improve the engine power and torque has taken a new step. The piston is already on heavy duty turbo-cooled cargo
