An automotive structure was further optimized

1 automobile fuel supply system modification
Gasoline engine fuel supply system from the traditional carburetor fuel supply system developed to electronically controlled fuel injection system in the process, which also experienced the development of mechanical fuel injection system and electromechanical hybrid fuel injection system. Electronically controlled fuel injection system is experienced by the single point of injection to multi-point injection, by injection into the outer cylinder direct injection of the development process.(engine parts) In the fuel system of continuous improvement process, engine power rising, declining fuel consumption, emissions towards the development of more stringent targets. Although electronically controlled fuel injection system technology has developed more mature, but if its a reasonable modification, still be able to further increase the engine power.
(A) to increase air flow and reduce intake resistance. Dress high flow air filter can reduce engine intake resistance, while improving the volumetric efficiency of the intake air and the engine running unit time. If you want to achieve better results, but also the entire air filter adapted to filter exposed filter, commonly known as the "mushroom head" (Figure 1),（Audi Turbo） in order to further reduce intake resistance, increase the engine intake air.
(2) change the shape of the inlet, increasing the intake air flow rate. Inlet improvements from the shape and material of two aspects to be. Changing the shape of the inlet, first, in order to achieve the intake pressure accumulator to the need for full throttle suddenly when hard acceleration; second is to increase the flow rate of the intake air. Changing inlet material, the material requirements of the principle is not absorbing and light quality. Currently the most common car modification carbon fiber material, the advantage of having no endothermic properties, the disadvantage is expensive. Typically racing will also improve the shape and material inlet and the air filter be transferred or simply removed, the air inlet extends to the car, in order to improve the speed with increased intake pressure, thereby enhancing the intake air to seeking to obtain maximum lifting power of the vehicle.（volvo turbo）
