Engine work, carburetor oil pump room has a side back to porosity, the pass-through crankcase, when crankshaft around a circle, as the piston moves up and down, the gases in the piston in and out of the pores, even following the carburetor oil pump chamber diaphragm vibration.Due to the effect of air flow, accelerated the feed velocity, accelerate the speed of oil, and at the same time start the quantitative chamber diaphragm vibration, the vibration of the quantitative chamber diaphragm compression reeds, carburetor start oil absorption, shunt, injection.
