随着石油燃料的日渐缺乏和国际市场石油价格的不断提高,燃料的高效率利用愈来愈显得重要。汽车制造厂应生产出低油耗的汽车。如现在的汽车仍象前几年一样采用提高压缩比的方法,就有可能产生爆震,性能就会下降,因为尚未研制出具有足够高辛烷值的汽油。采用喷水的方法可以解决高压缩比爆震的问题,并进而提高发动机性能、降低耗油量。这就是美国弗吉尼亚工程协会负责人宣称的具有喷水装置的发动机。这种发动机具有13:1的压 With the increasing lack of petroleum fuels and rising oil prices in the international market, the efficient use of fuels is increasingly important. Automobile manufacturers should produce cars with low fuel consumption. If today’s cars still use the same method of increasing the compression ratio as they did in previous years, there is a risk of detonation and performance degradation as no gasoline with sufficiently high octane has been developed. The use of water spray method can solve the problem of high compression ratio knock, and thus improve the engine performance, reduce fuel consumption. This is the engine with a sprinkler declared by the head of the Virginia Engineering Association. This engine has a 13: 1 pressure
