Abstract
The utility model relates to a breathing system of a 2.8L turbocharging diesel motor. The system comprises a cylinder head cover, a ventilation hose, an oil-gas separator, an oil return hose and an oil sump, wherein the cylinder head cover is internally provided with an oil-gas separation clapboard; the oil-gas separation clapboard and the interior of the cylinder head cover form labyrinth space; one end of the ventilation hose is connected with a ventilation pipe orifice of the cylinder head cover, and the other end is communicated with an air inlet of the oil-gas separator; one end of the oil return hose is communicated with an oil return opening of the oil-gas separator, and the other end is communicated with the oil sump; and the oil-gas separator is a filter element type oil-gas separator. For the system, the labyrinth space in a cylinder head cover assembly and the filter element type oil-gas separator are serially connected for conducting two-stage oil-gas separation on gas in a crankcase, therefore, the oil-gas separation efficiency is enhanced, the oil expelling amount of the crankcase is controlled to be below 1.0g/h, and the pressure of the crankcase is effectively controlled to be within (-1.5-+1.5) kPa.
Description
Technical field
The utility model belongs to technical field of internal combustion engines, is specifically related to a kind of respiratory system of 2.8L state IV diesel engine.
Background technique
The respiratory system of diesel engine is also referred to as crankcase ventilation system, and this system makes crank case gases communicate with atmosphere and carries out " breathing ".Respiratory system simply can be divided into two kinds of open type respiratory system and rebreathers.The open type respiratory system is that crank case gases directly or after simple Oil-gas Separation is arranged to atmosphere; Rebreather is crank case gases to be incorporated into air inlet pipeline mix with fresh air, enters the firing chamber then and burns.Rebreather is PCV system (PCV system) again.Along with the increasingly stringent of Abgasgesetz, at present, the petrol engine mandatory requirement adopts PCV system, and diesel engine does not have the laws and regulations requirement of this respect, but in order to improve the performance of diesel engine, the respiratory system of enclosed has begun to adopt in many producers.The rebreather of existing diesel generally adopts labyrinth type oil gas separating device or cyclone type oil-gas separator, and separating effect is not good, and its crankcase is scurried oil mass much larger than 1g/h, and crankcase pressure can not be controlled effectively.
The model utility content
In order to reduce the machine oil content in the crank case gases, improve burning, satisfy diesel engine state IV emission request, the utility model provides a kind of respiratory system of 2.8L turbo-charging diesel motor.
Concrete architecture advances technological scheme is as follows:
A kind of respiratory system of 2.8L turbo-charging diesel motor comprises valve mechanism cover, vent hose, deaerator, oil return flexible pipe, is provided with the Oil-gas Separation dividing plate in the described valve mechanism cover; One end of vent hose is connecting the ventilation mouth of pipe of valve mechanism cover, and the other end is being communicated with the suction port of deaerator; One end of oil return flexible pipe is being communicated with the return opening of gas separating device, and the other end is being communicated with oil sump; Mazy type space of the inner formation of described Oil-gas Separation dividing plate and valve mechanism cover; Described deaerator is the filer element type deaerator.
The return opening of described deaerator is at least 320mm apart from the height of oil sump machine oil liquid level.
Useful technique effect of the present utility model embodies in the following areas:
1, the utility model adopts the interior mazy type apart of valve mechanism cover and the two-stage Oil-gas Separation measure of filer element type deaerator, has improved oil gas separation, scurries oil mass much smaller than 1.0g/h, has reduced consumption of lubricating oil, helps engine emission.
2, the filer element type deaerator is integrated with pressure regulator valve, pressure controlled valve and removable filter core, and pressure regulator valve can be regulated crankcase pressure; When filter core stopped up, crank case gases caused pressure and raises in the inner gathering of deaerator.When pressure was elevated to certain value, the pressure control opening of valves prevented overpressure; Filter core is removable, and the filter core after the replacing can be done innocuity treatment, and environmental protection is economic and practical.Crank case gases is done the pre-separation of oil gas in the labyrinth of valve mechanism cover component, make that the machine oil content in the oil gas reduces, and can prolong the working life of filter core.
3, the utility model can be with crank case pressure control at (1.5～+ 1.5) kPa, the engine power consumption of having avoided sealing part leakage of oil that the crankcase malleation causes too greatly and crankcase negative pressure to bring too greatly.

Fig. 2 is that valve mechanism cover and Oil-gas Separation partition position concern schematic representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done to describe further by embodiment.
Embodiment:
Referring to Fig. 1, a kind of respiratory system of 2.8L turbo-charging diesel motor comprises valve mechanism cover 1, vent hose 3, filer element type deaerator 2 and oil return flexible pipe 4, and filer element type deaerator 2 is fixedly mounted on the intake manifold 6 by support 5.Oil-gas Separation dividing plate 8 is installed in the valve mechanism cover 1, and Fig. 2 is seen in mazy type space of Oil-gas Separation dividing plate 8 and valve mechanism cover 1 inner formation.One end of vent hose 3 is connecting the ventilation duct 9 of valve mechanism cover, and the other end is being communicated with the suction port of filer element type deaerator 2; One end of oil return flexible pipe 4 is being communicated with the return opening of filer element type deaerator 2, and the other end is being communicated with oil sump 7.The return opening of filer element type deaerator 2 is at least 320mm apart from the height of oil sump machine oil liquid level.
Claims (2)
