2, parts life-span prolongs, and reduces service expenditure:

After using this automatic clutch displacer, speed change is power-transfer clutch and the force aid system that operates the clutch originally, uses once when having only starting, and the access times of driving power-transfer clutch have reduced 4/5 with comparing originally in the city like this, access times have lacked, and it is just little to wear and tear.Speed change need not be banged throttle, the phenomenon of gear can not occur beating, will protect driving engine and speed-changing gear box like this, and parts life-span can prolong naturally.Service expenditure has also reduced.

3, save fuel oil, reduce blowdown, help environmental protection:

During original speed change is to carry out under the situation of open the throttle wide, after using this automatic clutch displacer, speed change is carried out turning off under the main throttle situation, naturally than original fuel-efficient, and fuel saving ratio is very considerable, and the city fuel saving ratio can reach more than 15%, and long-distance car fuel saving ratio can reach more than 30%, saved fuel oil, natural blowdown has just reduced.

During original speed change, Hong throttle is in order to put into gear well, and engine fuel is many and do not do work, burn often insufficient (row's black smoke), so blowdown is just many.Use this automatic clutch displacer can eliminate idle fuel oil, reduce blowdown and help environmental protection.
