1 概述为适应市场需求,日野公司从1987年9月起新生产了一种V型8缸、非增压的F17C型发动机。该机是在原日野EF750型的基础上提高功率而发展起来的机型,作为工程车辆用的动力。开发该机型的目的如下: a.适应市场高功率化的需求,但仍采用非增压,以保持其优良的起动性、加速性和低速大扭矩的性能; b.通过改善燃烧提高热效率、优化进气系统提高体积效率、以及减小摩擦损耗等措施实现非增压机型的最佳燃油耗率;
1 Overview In order to meet the market demand, Hino began producing a V-8, non-supercharged F17C engine from September 1987. This machine is based on the original Hino EF750-based model to increase power and developed models, as engineering vehicles with the power. The purpose of developing this model is as follows: a. To meet the market demand for high power, but still non-pressurized to maintain its excellent startability, acceleration and low speed high torque performance; b by improving combustion to improve thermal efficiency, Optimize the intake system to improve the volumetric efficiency, and reduce friction loss and other measures to achieve the best fuel consumption rate of non-supercharged models;
