Turbocharged diesel engine technology is more suitable

Diesel engine turbocharger reason often used
         In fact, to understand the problem, as long as the understanding of the characteristics of the diesel fuel and gasoline after two naturally be able to draw conclusions, and for diesel engines, either naturally or suction turbine engine, it's better than a gasoline engine compression ratio higher.
         Gasoline engine compression ratio is usually about 10 or so, even lean burn engines FSI compression ratio can only be close to 11, and the compression ratio of the diesel engine 19 generally, and even higher than 20. The reason is that diesel has a better than gasoline antiknock. That is more difficult to ignite than diesel fuel, Citroen 1.6 turbo the combustion speed is much slower than gasoline, so more stable nature. So, you need a higher compression ratio in the high-pressure environment so that the diesel was compression-ignition.
   
         Further, the diesel engine has a fuel supply means is also very different from the gasoline engine, the gasoline engine, the fuel is often injected into the intake manifold of which, that has been sucked into the cylinder of the gas mixture, if at this time inside the cylinder temperature and pressure is too large it is easy to make the mixture ahead of the combustion; often use high-pressure jet engines, for the use of TDI engines, using direct injection, so the fuel is injected into the piston until the end, plus antiknock itself have been very good, so naturally have the engine compression ratio than gasoline engines can improve a lot. In the combustion temperature, the introduction of supercharged diesel engine technology it is much easier than a gasoline engine. Mini 1.6 turbo The compressed intake efficiency can be further improved diesel engines, in fact, prior to the development of the Porsche VTG technology, this variable vane turbocharger has been used in a diesel engine.
          This technique is not turbocharged mysterious and novel nouns, and can effectively increase the output power of the engine, making the car to get a strong momentum. So, Ford 1.6 turbo the diesel engine is more suitable than the gasoline engine turbocharging technology more easily accepted.
