Technical field
The utility model relates to technical field of engines, specifically a kind of crankcase ventilation system for solving ice and blocking up failure.
Background technique
Piston, piston ring and the cylinder body of engine are relative movement part, so being clearance fit in design.In engine
It carries out under compression stroke, the working condition of exhaust stroke, since the pressure of combustion chamber is larger, the gas of combustion chamber can be from combustion chamber
Into engine crankcase, crankcase gas blowby is thus brought.
The main component of engine crankcase gas blowby is fuel particle, vapor and machine oil particle.Current power machine crankshaft
Box ventilation system oil-gas separation efficiency is continuously improved, and machine oil content accordingly reduces in crankcase waste gas, and water content accordingly increases.
In extremely frigid zones such as northeast, winter temperature is lower, and the vapor in engine crankcase gas blowby can be condensed into water afterwards to the cold, in turn
Crankcase ventilation system is easy to happen icing phenomenon, or even can block crankcase bleed pipe, causes crankcase pressure to increase, causes
Engine crankcase oil leak, situation is serious to will cause engine damage.
Utility model content
The purpose of this utility model is to provide the crankcase ventilation systems that a kind of solution ice blocks up failure, to solve above-mentioned back
The problem of being proposed in scape technology.
To achieve the above object, the utility model provides the following technical solutions:
A kind of crankcase ventilation system for solving ice and blocking up failure, including what is connected with air cleaner and engine supercharger
Booster air inlet tube, the crank case vent valve being assemblied at the top of engine air cylinder cap and crankcase ventilation hose, the increasing
Having heaters is installed on the mounting hole of depressor air inlet tube, crankcase ventilation hose both ends respectively with heater and crank case vent
Valve is connected, and is also equipped with crankcase pressure sensor at the top of engine air cylinder cap, the outside of crankcase is equipped with temperature sensing
Device.
As a further solution of the present invention: the heater, crankcase pressure sensor, temperature sensor are distinguished
It is connect with control unit of engine.
The battery is connect with control unit of engine as a further solution of the present invention,.
Compared with prior art, the utility model has the beneficial effects that
1, the working condition of heater is controlled according to the signal of temperature sensor by control unit of engine, in low temperature ring
Heating function is opened under border, closes heating function under non-cryogenic environment, by the heat effect of heater, can avoid occurring bent
Ventilation system for shaft box ice blocks up phenomenon;
2, pressure of the control unit of engine according to the signal of crankcase pressure sensor, such as crankcase pressure lower than setting
Value then carries out fault alarm even engine and shuts down, and protects the blocking due to crankcase ventilation system to cause engine with this
The failures such as damage.
