Reduce the emission label to improve

Recently, Beijing is new fuel standard released draft version, this is actually the kingdom of implementation for the next 5 emissions standards try water. The new standard where change? For all concerned, what influence and the role? In face of the new standards to the interpretation of, can let your these solved the problem. (as Beijing on diesel power small buses have restrictions, so we chose the vast number of consumers are more concerned about the standard for the interpretation of the gasoline.)Different chemical structure of hydrocarbons, have different anti-explosion earthquake ability. Michael essien vision silane (2 4-trichlorobenzene three methyl 1-bromopentane) was the better properties, octane to set at 100. Refine n-heptane was the bad property, to is set to "0". The determination of gasoline octane number is different polyurethanes and essien to refine n-heptane for standard fuel, according to standard conditions in the laboratory standard on single cylinder petrol with correlation method. Adjust the proportion of standard fuel composition, make standard of fuels the knock intensity and sample the same, this time the standard fuel vision of silane essien the volume occupied by the percentage is the octane value of the sample. According to the different determination conditions.Determination conditions are harsh, engine speed for 900 r/min, inlet temperature of 149 ° C. It reflects the highway, heavy load conditions of anti-explosion sex drive gasoline.Determination conditions were relieved, rotating at 600 r/min, intake for room temperature. The octane reflect in the city car slow speed of anti-explosion sex when gasoline. For the same kind of gasoline, the study of high octane rating than motor octane rating about 0 ~ 15 units, both between difference says sensitivity or sensitivity.Also called driving octane, use the car was measured in all the power test or on the car driving on the highway in car DVD simulation of determination conditions. Road octane can also be used motor method and the method of calculating formula obtained according to experience octane rating. Motor method and the average of the octane value method of octane rating called anti-explosion index, it is able to say road octane.Say simply, is a new label gasoline octane rating and label, anti-explosion sex all reduced, at the same time, sulfur, manganese, lead more strict control. Among them, the gasoline label (90, 93, 97) is the octane value of the gasoline, octane gasoline engine and knock about, refine n-heptane blast degree of the most serious, defines the octane value is 0. Michael essien was different, are best shock function, the octane definition for 100. So-called 90 number, 93, no. 97 unleaded gasoline, it is to show they are equivalent to contain 90%, 93%, 97% of the earthquake was strong ability of Michael essien vision of the car cameras silane, at the same time, contains respectively 10%, 7%, 3% of the poor ability of anti-explosion shock to refine n-heptane (actually the gasoline is a complex mixture of various hydrocarbon compounds, not only contain different polyurethanes and essien to refine n-heptane, this statement is to calibrate and understanding of the convenient). Gasoline change of label means of gasoline octane number change, at the same time the gasoline anti-explosion nature will change.
