The car engine is in the design phase, and the fuel used for the compression ratio is set. The compression ratio is a very important structural parameter of the engine, which indicates the volume of the gas at the beginning of the piston at the beginning of compression and the volume ratio of the gas volume at the end of the piston. In terms of power and economy, compression ratio should be bigger and better. The compression ratio is high, the power is good, the heat efficiency is high, the vehicle acceleration, the top speed of the car will be improved accordingly. However, the compression ratio of the gasoline engine is not too large due to the performance of the cylinder material and the vibration of gasoline combustion. In short, a high compression ratio USES a high grade fuel oil. The higher the fuel mark, the slower the oil will burn, and the lower the combustion detonation, the higher the compression ratio of the engine. On the contrary, the low-grade fuel combustion rate is faster, the combustion explosion is large, the engine compression is lower. At present, there are 89, 92, 95 and other labels on the market, which represent the octane value of gasoline, which means the anti-detonation of gasoline, which has nothing to do with the cleaning of gasoline. The so-called "high label gasoline is cleaner" is misleading. It is more scientific, more economical, and can give full play to the engine's efficiency according to the engine compression ratio or the requirement of the automobile instruction manual. Banks like ICICI bank, Axis bank, State Bank of Indore, HDFC Bank, State Bank of Patiala, Bank of Baroda, Union Bank, Punjab National Bank, etc. Also, you get some discounts or sizzling offers when you receive your cell recharged through online. If you are using the debit card or plastic card of some another bank which will not demonstrate the tab of “online recharge” in their official website than merely go to Google online recharges . After that you came to realize that bank supply you service of online recharge or otherwise. According to the latest standard GB/T 3730.1-2001, cars are mainly divided into passenger cars and commercial vehicles.
