Does gasoline No. 93 plus 97 cause detonation?
Don't knock, nor can add speed to accelerate, but without cleaning, in addition, it is a reminder that the domestic 97# is actually not the label in the world, the label should be 98#, is my own preparation, it is through the 93#, add a variety of ingredients produced. Then, because they can not meet the requirements of 98#, so to label a 97#
High compression ratio of the engine, if the use of low grade gasoline, will cause the cylinder temperature rise, gasoline combustion is not complete, the machine vibration, so that the output power down, damage to parts. Low compression ratio of the engine forced to use high mark oil, there will be "delay burning" phenomenon, that is, the pressure to the head, it is not to spontaneous ignition points, the same will appear incomplete combustion, the engine is also no good.
The grade of gasoline only indicates the octane number of gasoline, and different grades of gasoline should be chosen according to the difference of engine compression ratio. The compression ratio in 8.59.5 between mid-range cars in general should use 93 gasoline; compression ratio greater than 9.5 should use the 97 gasoline cars. At present, the compression ratio of domestic cars is generally above 9, and it is better to use No. 93 or no. 97 gasoline.
The so-called No. 97 gasoline is 97% isooctane, 3% heptane. In the case of high compression ratio, high octane gasoline should be used. If compression ratio is high, low octane gasoline will cause abnormal combustion, resulting in shock, oil consumption and driving disability.
