subject: Good use of fuel for their vehicles to remind the compression ratio of oil - fuel, compression ratio - auto repair and maintenance industry [print this page] Company Sinopec Hubei Sell Chang Tan, director, said nearly 20 million owners of almost all civilian in the wrong use of gasoline.
Compression ratio is achieved when the piston in the cylinder movement when the ignition cylinder volume with the volume ratio. It is the only standard petrol car owners choose. If you use oil and compression ratio do not match, it will produce a series of serious consequences. For example, if the engine oil is designed according to 93, while the owners of No. 90 with a gasoline engine combustion phenomenon occurs early, and then produce an instant high moderate high pressure, not only burnout Spark Plug , Cylinder, etc., would produce useful work, resulting in vehicle acceleration, climbing weakness, but also to produce gasoline olefin resin, so that the sulfur in gasoline in the incomplete combustion produces a highly corrosive, causing the exhaust pipe and other corrosion.
According to Tam-Chang, China's gasoline Weijun Jiang experts believe that 60% of the scrapped vehicle is directly or indirectly caused by the wrong oil. General Tan said, according to their calculations and observations, the current compression ratio in the car mostly in 9.0 above, and some imported cars compression ratio even at 12, should be used for more than 95 petrol (on imported vehicles should be used for more than 97 oil), but the current oil Hubei in the car's actual situation, 80% of the vehicles are the wrong oil.
Car easy Keep a car Difficult
Reason is twofold: First owner to save money, deliberately low-grade oil. Tan always said, more than 90 oil 93 oil only your 6 cents, but due to the owner in order to save 6 cents for the wrong caused by the oil, get it calculated by million Vehicle Maintenance Charge loss.
Second, owners of automobile manufacturers deliberately set the trap. For example China has a relatively well-known car, a description on the label is "recommended for more than 91 gasoline." And our country simply do not 91 oil, so some owners do not think that 91 is the most suitable oil, then oil with 93, two high, with 90, one less oil, plus chart cheap psychology, the owner will be selected No. 90 oil. What is more, many car factory specifications on the car simply does not indicate the compression ratio, some merchants are sales to buyers who do not introduce compression ratio, leading many car people ignore this important issue, only to note power concentrated in the paint, Airbag , CD and so little to do with the car's configuration properties. Why would auto makers
same word about the compression ratio, reason is that they sell out in order to facilitate the car. Such as Wuhan, a few years ago, "Big Ben hit" event, the conclusion now is that owners of motor vehicles caused by the wrong oil. Mercedes-Benz Car in a foreign country must be 98 oil, and our supply of oil with 97 very little. Mercedes-Benz vehicle owners if a big way, the oil must be 97, who bought his car? Therefore, Mercedes-Benz cars imported into China, the ignition location were adjusted a bit in advance, so that the Chinese owners of "chronic Smashing cars" (Wuhan Pushing Big Ben said to be smuggled cars, no transfer, so the old climbing nest). Car Service Factory owners also deliberately concealed the truth, because only allow car owners to use the wrong oil cause damage, they have business.
For manufacturers such "Kengren" behavior, the owner can only " ?? ", told manufacturers not to use, because we do not have relevant laws. Require oil companies to change the status quo is not realistic, because the cancellations of a low-grade oil blending facility and then a high-grade oil facilities, oil companies to invest a billion dollars, but was offset by the owner used the wrong oil. In order to reduce losses, the total TAM repeatedly stressed in the car car be sure to ask what the compression ratio is the number of cars in the car owners also have to figure out what your car is the compression ratio, and then on the "disease" oil . Method is simple, that is, "My oil refining me"?? Their own cars for the related blending grade oil.
Blending the following criteria: 3 were 93 oil were 97 +1 = 94 oil oil
1 +3 copies were 93 oil 97 oil 96 oil =
