kath oil 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. The bank of England says Britain is a European banker, and the imf welcomes the progress of Brexit - and that's what happened British Glass is organising a one-day seminar on funding for decarbonisation and energy efficiency work on Thursday 2 November (north of England, venue TBC) – which will be attended by British Glass members’ and non-members. But the DRAM and NAND semiconductor industries have gone from boom to bust in the face of rising prices and the abundance of falling prices. Will it be any different this time? Or is the need for mobile device memory and disk replacement sufficient to continue to delay the abundance until the foreseeable future? It is our responsibility to achieve our goals in the right way in 2018, and we have this opportunity. It is generally believed that the v-shaped engine is a relatively advanced engine, which also becomes a symbol of the sedan grade. At present, the most common engines are the straight-line 4 cylinder (L4) and v-type 6 cylinder (V6) engine. In general, the V6 engine has a higher displacement than L4, and the V6 engine runs smoothly and quietly than the L4 engine. A V6 engine is usually mounted on a mid-grade sedan.
