Variable Lexia-3 USB Cable intake manifold

Simple. The engine of the car the  Lexia-3 USB Cable  two most important elements: 1. The low-speed torque. 2. High-speed power. Not say, just say the intake system.

And hard acceleration when overtaking car just started to feel powerful and cool, it is necessary to have the torque. While the car faster unpleasant, which is related to the problem of high-speed power.

Question now back in the case of unchanged in other configurations of the car, if using thin and long intake manifold, in the case of low engine speeds, can increase the intake air flow speed and the pressure intensity, and so that the gasoline can be better atomization, better combustion. {Like if we want strong flow of water, put the water pipes pinch flat is the same reason}.

Instead, this configuration also has shortcomings, is when the engine pulled at high speed into the gas per unit of time, due to the manifold too thin is not enough, the result is that speed could not pull up the car high-speed run does not come out. Then you need to manifold thick and short, in order to draw in more gas.

In order to allow the  Cable for Renault Can Clip engine to have low-speed torque, but also pull out the high-speed, most of the car now equipped with variable manifold or dual manifold.

Dual manifold and cylinder head intake a two manifold connections between the air intake for the carburetor (EFI), a stubby straight to a slender curved (mostly with a curved slender degrees), with variable valve control (like the human throat airway and esophagus). Usually gas to go thin tube, the valve closes automatically when the speed reaches a certain height, the gas to go thick pipe.

Variable manifold looks is a thin tube sets in a thick tube. The structure is different, the principle is the same.
