Description
Technical Field
The utility model relates to the technical field of engines, especially, relate to a multi-functional takeover that admits air.
Background
The current air inlet connecting pipe of the engine has a single function, generally only meets the air inlet requirement of the current engine, and an EGR (exhaust gas recirculation) system is a common configuration according to the requirements of the current national six-emission regulations. Meanwhile, a mixing port of the EGR waste gas and the fresh air needs to be arranged behind a throttle valve, and an air inlet pipe is usually connected with an EGR waste gas pipeline by adopting a scheme of opening a flange at a certain position.
The air inlet connecting pipe designed by the conventional scheme has the defects of unsmooth air inlet, no air inlet interface for EGR waste gas, single function and incapability of supporting other accessories of the engine due to the narrow space and the existence of interferents.
Chinese patent (CN207212515U), discloses an air intake pipe connection device of a natural gas engine, comprising: the explosion-proof valve comprises an air inlet connecting pipe, an explosion-proof valve base, an explosion-proof valve and an air inlet temperature and pressure sensor; the explosion-proof valve base is installed on the air inlet connecting pipe through a bolt, the explosion-proof valve is fixed on the explosion-proof valve base through the bolt, and the head of the air inlet temperature and pressure sensor is inserted into the air inlet connecting pipe and is screwed up through the fixing bolt.
Above-mentioned prior art does not integrate all kinds of annex installation bosss on the takeover admits air for structural arrangement is highly compact inadequately, and the function is comparatively single.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the utility model provides a multifunctional air inlet connecting pipe, which adopts the variable cross-section design to solve the problems of air inlet resistance and adverse air inlet uniformity of each cylinder; the EGR waste gas is provided with a circulation interface, mixed exhaust improves the inlet air temperature, emission pollution is reduced, and various accessories are integrated with the mounting bosses, so that the arrangement height is compact, and the problem of single function is solved.
The utility model discloses take following technical scheme to realize above-mentioned purpose:
the utility model provides a multi-functional intake is taken over, includes that the intake takes over the body, the relative both ends of taking over the body of admitting air are equipped with air inlet and gas outlet respectively, still include waste gas and admit air interface and two at least annex installation bosss, waste gas admits air the interface and establishes the lateral surface of taking over the body and communicate the medial surface of taking over the body of admitting air at the lateral surface of taking over the body of admitting air, annex installation boss interval arrangement is in the outer wall of taking over the body of.
Preferably, the sectional area of the inner cavity of the air inlet connecting pipe body along the air flow movement direction is gradually increased, so that the air inlet resistance can be reduced, and the power loss can be reduced.
Preferably, the cross section of the inner cavity of the air inlet connecting pipe body is transited from a circle to a square along the air flow movement direction, so that the flowing air is turbulent, and the air is mixed more fully in a relatively short pipeline, thereby obtaining excellent power performance.
Preferably, the gas inlet and the gas outlet are vertically arranged, so that the mixing efficiency of the gas is further improved, and the uniformity of the mixed gas is improved.
The utility model has the advantages that:
1. various accessory mounting bosses are integrated, so that the problem of mounting and arranging various accessories is solved, and the arrangement height is compact.
2. The variable cross-section design of the air inlet connecting pipe body can reduce air inlet resistance and power loss, so that air flowing through forms turbulent flow, and the air is more sufficiently mixed in a relatively short pipeline, thereby obtaining excellent power performance.
3. And an EGR waste gas inlet interface is added, so that the air inlet temperature of the engine is improved by mixing the inlet air with the EGR waste gas, and the emission pollution is reduced.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings 1-4 and the detailed description thereof.
Please refer to fig. 1, fig. 2, fig. 3 and fig. 4, the embodiment of the present invention provides a multifunctional air inlet adapter, which includes an air inlet adapter body 1, and air inlets 2 and air outlets 3 are respectively disposed at two opposite ends of the air inlet adapter body 1. The utility model discloses a multi-functional takeover that admits air still includes waste gas interface 4 and two at least annex installation bosss 5. The waste gas inlet interface 4 is arranged on the side surface of the inlet connecting pipe body 1 and close to the gas inlet 2. The accessory mounting bosses 5 are arranged on the outer wall of the air inlet connecting pipe body 1 at intervals.
When the multifunctional air inlet connecting pipe is used, firstly, fresh air enters the air inlet connecting pipe body 1 from the air inlet 2, and EGR waste gas enters the air inlet connecting pipe body 1 from the waste gas inlet interface 4; then, the fresh air and the EGR waste gas are uniformly mixed in the air inlet connecting pipe body 1, and the air inlet temperature of the fresh air is improved, so that the aim of reducing emission pollution is fulfilled; the mixed gas after being mixed uniformly flows out from the gas outlet 3. The accessory mounting boss 5 is used for mounting and arranging various accessories, so that the arrangement height is compact.
Further, the cross section of the inner cavity of the air inlet connecting pipe body 1 is transited from a round shape to a square shape along the air flow moving direction, the sectional area is gradually increased, and meanwhile, the air inlet 2 and the air outlet 3 are vertically arranged, so that the problems of air inlet resistance and air inlet uniformity of each cylinder are solved.
Further, in the present embodiment, the accessory mounting bosses 5 include four to facilitate mounting arrangement of a plurality of accessories. The accessory mounting boss 5 can be used for mounting and fixing an engine wiring harness mounting bracket, an oil scale sleeve mounting bracket and the like. Functionally, the accessory mounting boss 5 can also be used to secure other items, such as providing mounting support for other parts.
Although the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that modifications and improvements can be made thereto. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
