减小汽车自身的质量和减小发动机质量一直是具有重要意义并富有挑战性的课题，而缸体在这方面占有重要的比例。采用铝合金材料是缸体减小质量的一种重要途径，但是铸铁缸套则成为进一步减小质量的障碍。本田公司提出了一些设想：1）采用高共晶铝硅合金（A390）材料；2）在铝质
Reducing the car’s own mass and reducing the engine mass has always been an important and challenging subject, with the cylinder body occupying a significant proportion of this area. Aluminum alloy material is an important way to reduce the mass of the cylinder, but the cast iron cylinder liner has become an obstacle to further reduce the quality. Honda made a number of assumptions: 1) the use of high eutectic Al-Si alloy (A390) material; 2) aluminum
