Excuse me １ . Taking energy of life 2 times is what action.

2. Air is gush entering still is vent-pipe inside cylinder inside, what effect is there? Thank

" car knowledge " answer: Taking energy of life 2 times is to point to besides original from air filter outside inspiratory air, additionally recycle enters the vacuum pressure of gas manifold to differ, enforce from engine PCV(crankcase ventilated) the another unit that take energy of life is received outside pipeline, guide right amount fresh air will achieve the goal that improves cubage efficiency.
The dynamical promotion result that can get 2 times into gas is the mainest is in engine low rotate speed when, because be in throttle a standard-sized sheet, air is entered in great quantities, vacuum is spent when reducing, the empty tolerance that can guide 2 times into gas unit becomes negligible relatively. It is the most important to take gas unit 2 times is to should be maintained " right amount " take energy of life, the method that at present the difference of the product on market depends on control guiding airy enters tolerance has each different. If the quantity into gas is too little, criterion the effect not beautiful, too much can reduce vacuum to spend, affect the auxiliary force of booster of brake vacuum motivation, make brake place needs a force to become heavier, and so called " right amount " the result that is earning of manufacturer research, experiment.
