1 前言从石油冲击开始的节省资源和能的动向中,作为降低汽车燃料消耗的主要手段——减轻自重(轻量化)已提到了议事日程。对于小轿车,从轻量化能直接降低燃料消耗这一观点出发,实行了小型化(车型变小)、FF(前置发动机前轮驱动)化(FF车增加)、采用轻材料等措施。载重车的轻量化和小轿车稍有不同,它不仅要降低燃料消耗,还要在法规准许的范围内,增加载重量。
1 Introduction From the resource conservation and energy dynamics that began with the oil shock, the agenda has been mentioned as the primary means of reducing fuel consumption in automobiles - reducing self-regard (weight reduction). In terms of lightweighting, it is possible to reduce the fuel consumption by directly reducing the size of a car, reducing the size of a car, increasing the front-engine FF driving force, and increasing the use of light materials. The weight of a truck is slightly different from that of a car. It not only reduces fuel consumption, but also increases the load capacity within the range permitted by the law.
