汽油抗爆剂厂家教您提高石油的辛烷值?

辛烷值是车用汽油的重要的指标,而汽油抗爆剂的使用可以提高汽油中的辛烷值,是非常普遍的一种方法,接下来我们介绍一种测定辛烷值的方法。

Octane number is an important index of vehicle gasoline, and the use of gasoline antiknock agent can improve the octane number of gasoline, which is a very common method. Next, we introduce a method to determine the octane number.

1、马达法辛烷值 测定条件较苛刻,发动机转速为900r/min,进气温度149°C。它反映汽车在高速、重负荷条件下行驶的汽油抗爆性。

1. The engine speed is 900 R / min and the intake air temperature is 149 ℃ ° C。 It reflects the gasoline antiknock performance of automobile under the condition of high speed and heavy load.

2、研究法辛烷值 测定条件缓和,转速为600r/min,进气为室温。这种辛烷值反映汽车在市区慢速行驶时的汽油抗爆性。对同一种汽油,其研究法辛烷值比马达法辛烷值高约0~15个单位,两者之间差值称敏感性或敏感度。

2. The conditions of octane number determination by the research method are mild, the rotating speed is 600r / min, and the inlet air is room temperature. This octane number reflects the antiknock performance of gasoline when the car runs at a slow speed in the urban area. For the same gasoline, the octane number of research method is about 0-15 units higher than that of motor method, and the difference between them is called sensitivity or sensitivity.

3、道路法辛烷值 也称行车辛烷值,用汽车进行实测或在全功率试验台上模拟汽车在公路上行驶的条件进行测定。道路辛烷值也可用马达法和研究法辛烷值按经验公式计算求得。马达法辛烷值和研究法辛烷值的平均值称作抗爆指数,它可以近似地表示道路辛烷值。

3. Road octane number, also known as driving octane number, is measured by vehicle or simulated on the full power test bench. Road octane number can also be calculated by motor method and research method according to empirical formula. The average of motor octane number and research octane number is called antiknock index, which can approximately represent road octane number.

提高汽油发动机效率有效的办法是提高发动机的压缩比,但压缩比一提高,爆震燃烧明显增强,需要用更高辛烷值的汽油来减小爆震,随着发动机压缩比不断提高,这迫使炼油厂生产高牌号(辛烷值)的汽油。辛烷值的提高不仅减轻发动机的爆震,而且减少油料的消耗,从而增加经济效益,每提高汽油辛烷值1个单位,可节油1.3%。

The effective way to improve the efficiency of gasoline engine is to increase the compression ratio of the engine. However, with the increase of compression ratio, the knock combustion is obviously enhanced, and gasoline with higher octane number is needed to reduce the knock. With the continuous improvement of compression ratio of the engine, refineries are forced to produce high grade gasoline. The increase of octane number can not only reduce the knock of engine, but also reduce the fuel consumption, so as to increase the economic benefits. 1.3% fuel can be saved for each unit increase of octane number of gasoline.
