现代活寒式汽化器发动机的效率按以下指标评价:经济指标、动力指标、排放指标、结构简单性、工艺性、材料用量、生产过程自动化及现有设备利用率、结构可靠性、结构零件互换性、制造成本、使用成本和单位重量。我们面临的任务是提高伏尔加发动机厂生产的、总排量为4250 cm~3的、活塞式V型8缸发动机的效率,首先是提高动力指标和经济指标。该厂进行的理论研究表明,发劫机的动力指标可通过完善其工作过程,即提高燃油流量系数、指示效率和曲轴转速来改善。而这些指标的改进可通过工作混合气的均质化、预热进
The efficiency of modern live-type carburetor engines is evaluated by the following indicators: economic indicators, power indicators, emission indicators, structural simplicity, processability, material usage, automation of production processes and utilization of existing equipment, structural reliability, interchange of structural components Sex, manufacturing costs, operating costs and unit weight. The task we are facing is to increase the efficiency of the Piston V-8 cylinder engine with a total displacement of 4,250 cm 3, produced at the Volga engine plant. The first is to improve the dynamic and economic indicators. Theoretical studies carried out by the plant show that the horsepower indicators of hijackers can be improved by improving their work processes, ie increasing fuel flow coefficient, indicating efficiency and crankshaft speed. The improvement of these indicators can be through the working mixture of the homogenization, preheat into
