Abstract

The invention discloses an engine pressure balance system, which relates to the field of direct injection engines in gasoline cylinders. It includes air filter, air pump, air storage tank, solenoid valve, engine and sealed control cylinder, the air filter, air pump and air storage tank are connected in sequence; the air storage tank is connected with the third port of the solenoid valve; the solenoid valve The first port and the second port are respectively connected with the crankcase cavity and the intake pipe; the control cylinder is equipped with a control piston and a piston rod connected to it; the control piston seals the cylinder cavity on both sides; the left cavity of the control cylinder passes through The first conduit communicates with the inner cavity of the crankcase; the right cavity of the control cylinder communicates with the inner cavity of the cylinder on the upper side of the piston through the second conduit and the air passage; the two side walls of the control piston are elastically connected with the respective adjacent end cylinder walls through springs; the piston The distance between the left end of the rod and the two elastic contacts is 1mm. The invention can reduce the pressure difference between the upper side and the lower side of the piston in the cylinder, thereby reducing the phenomenon of gasoline running down and improving the lubricating stability of the engine oil.

Description

technical field [0001] The invention relates to the field of direct injection engines in gasoline cylinders, in particular to an engine pressure balance system. Background technique [0002] In the current gasoline direct injection engine, the air pressure on the upper side of the piston in the cylinder changes at any time with the change of the working stroke of the engine. Especially in the compression stroke, the air pressure in the cylinder on the upper side of the piston is much greater than the air pressure in the crankcase, and the unburned gasoline injected into the cylinder will flow into the crankcase through the end clearance of the piston or the gap between the piston and the cylinder wall. As a result, gasoline is mixed into the engine oil in the crankcase, causing the oil to be polluted and the lubricating performance of the engine oil to decrease. Contents of the invention [0003] In order to solve the problem of gasoline running down, the invention provid...
