The difference between the naturally aspirated and supercharged engin

With oil prices rising, and the increasingly stringent requirements of the national emission standards, more and more small-displacement supercharged engine is developed and fitted to most models, while supercharging technology is also More and more car manufacturers seriously.

  Them over the past 20 years, the turbo technology is widely used in diesel engines, but with the emissions requirements continue to increase, diesel exhaust particles are still difficult to solve problems in this stage of diesel exhaust and turbo systems.

   For the field of car modification, most people today think retrofitting turbocharged naturally aspirated engine is the best way to increase the power. Turbocharger body lower cost, and many stores also more opportunity to come into contact with the modified turbo system that most people are more likely to accept the turbo transformation. And after the installation of the turbo system, the relative power of the original car upgrade really obvious, so many owners will be more willing to own car installation set. 

 Due to the uneven the turbocharger quality level circulation, there is a big brand in Japan, the United States, there are some small label, as well as domestic imitations and "own brand". The price of the kit is very different from 3,5 10000-10000 yuan or less, the owner of the product of choice is also scratching their heads. And various construction techniques and technical capacity of the store is different, so many owners have grave doubts on kit aftermarket car, in the end, after Bahrain How long can, in the end, after Bahrain what damage the engine, in the end to install the product What is the quality, not to mention the owners, even if a lot of their own stores are confused.

 Above that is the distinction between hardware now talk about the difference between "software". In simple terms the intake and exhaust valve angle different design. Why? This involves the engine VE VE = volumetric efficiency. The highest naturally aspirated engines and turbocharged engine VE point design is a completely different direction. Naturally aspirated engine, as the name implies, is a downward movement by the piston, the combustion chamber generates a pressure difference, the outside air is sucked in relatively small angle between the intake and exhaust valves in the range of high VE, to protect the air sucked as little as possible from the exhaust valve to go.
