Abstract
A choker vent pipe is provided, which comprises a vent pipe (1), a valve cage hood (2), a crankcase (3), a choker (4), a choker (5) and a ventilation hose (6). The utility model is characterized in that: one end of the vent pipe (1) is connected to the choker (4) and another end is connected to the valve cage hood (2) via the ventilation hose (6); clean air is supplied to the crankcase (3) to dilute the waste gas in the crankcase (3).
Description
Technical field: the utility model relates to engine crankshaft ventilation system.
Background technique: in closed crankcase ventilation system, there are pressure difference in air-strainer inner air and crankcase internal waste gas, when air-strainer air pressure is higher than the crankcase internal air pressure, clean air in the air-strainer just enters crankcase dilution waste gas, and enters suction tude by the PCV valve and rekindle.Because the air filter does not have design and installation on motor,, can make ventilation sebific duct design relative complex, and then influence the cabin integral arrangement if get gas from air-strainer inside.In addition, in case crankcase waste gas refluence phenomenon appears, and may stained air cleaner cartridge.
Summary of the invention: the purpose of this utility model is, a kind of simple in structure, with low cost, easy for operation, Butterfly Throttle Air Chimney flexibly is provided.The purpose of this utility model is achieved in that it is made up of ventilation duct (1), valve cage case (2), crankcase (3), closure (4), closure (5), ventilating glue tube (6).Ventilation duct (1) one end is connected with closure (4), the other end is connected with valve cage case (2) through ventilating glue tube (6), and making provides clean air with waste gas in the dilution crankcase (3) in crankcase (3).The utility model has the advantages that: ventilation duct is connected on the air-strainer, utilizes waste gas in the clean air flushing crankcase after air-strainer filters.The utility model increases a ventilation duct on throttle body, utilize before the closure and the pressure difference in the crankcase, waste gas in crankcase provides clean air flushing crankcase.Advantage is that structure is compact more, can prevent that the oil gas backflow that may occur from causing the stained problem of air filter filter core.On throttle body, increase a ventilation duct, before closure, get gas, provide clean air dilution waste gas to crankcase.
Description of drawings: Fig. 1 is the utility model structural principle schematic representation; Fig. 2 is the utility model working principle schematic representation.5-closure, 7-PCV valve.
Concrete mode: ventilation duct (1) one end is connected with closure (4), the other end is connected with valve cage case (2) through ventilating glue tube (6), and making provides clean air with waste gas in the dilution crankcase (3) in crankcase (3).For usefulness ventilation sebific duct connects throttle body ventilation duct and valve cage case, and the valve cage case is communicated with crankcase.Owing to have pressure difference with crankcase before the closure, when air pressure before the closure was lower than the crankcase internal air pressure, the clean air before the closure will enter crankcase by ventilation duct, and (crankcase was the cavity that is formed by bent axle, cylinder body, lower crankcase.The part waste gas that produces during engine operation can enter crankcase), waste gas in the dilution crankcase.With ventilation duct and the valve cage case on the ventilation sebific duct connection throttle body, and the valve cage case is communicated with crankcase.Owing to have pressure difference with crankcase before the closure, when air pressure before the closure was lower than the crankcase internal air pressure, the clean air before the closure will enter crankcase by ventilation duct, and (crankcase was the cavity that is formed by bent axle, cylinder body, lower crankcase.The part waste gas that produces during engine operation can enter crankcase), waste gas in the dilution crankcase.When the pressure in the crankcase reached certain pressure, the PCV valve will be opened, and the gas in the crankcase will flow to intake manifold, thereby waste gas burning is fallen.
