活塞环弹力大小,直接影响内燃机工作过程的好坏。而工作中产生的高温高压燃气和磨损的影响,往往造成活塞环弹力的下降。因此,在检查中,必须检验活塞环弹力的大小,是否符合有关技术规定,以判断其密封性能,保证内燃机的正常工作。下面简介几种常用的检验方法。 Piston ring elastic size, a direct impact on the working process of the internal combustion engine is good or bad. The high temperature and pressure generated by the work of gas and wear and tear, often resulting in decreased piston ring elasticity. Therefore, the inspection, you must test the size of the piston ring elastic, whether in line with the relevant technical regulations to determine the sealing performance, to ensure the normal operation of the internal combustion engine. The following describes several commonly used test methods.
