【摘要】 提出一项提高内燃机部分负荷经济性的措施,即采用一种冷却油来替代冷却水以减少部分负荷下的热损失;在高负荷时,同采用内冷却以抑制爆震的产生。经台架试验证明,采用此项措施其油耗率可降低6～8％;道路试验表明,其等速百公里油耗可降低8～10％。更多还原

【Abstract】 A new compound cooling method is proposed to improve the IC engine performance.At part load condition the thermal loss of the engine is cut down with oil cooling;at heavy load condition the knock combustion is suppressed with internal water cooling.The stand-experiment shows that the fuel consumption reduces by 6~8 %,The road testing indicates that the fuel comsumption decreases by 8-10% for a car running at constant speed.更多还原
