Embodiment Construction

[0026] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0027] Such as Figure 1-3 As shown, the EGR mixer with double air intake structure of the present invention is composed of a mixer shell 1 and a Venturi mixer core 2 . The side wall of the mixer housing 1 is provided with a first exhaust gas inlet 11 and a second exhaust gas inlet 12 , and the mixer housing 1 is also integrated with an intake pipe, that is, an air intake pipe section 13 . The partition 21 divides the cavity between the mixer shell 1 and the mixer core 2 into two separate chambers, which are respectively connected to the first exhaust gas inlet 11 and the second exhaust gas inlet 12 . The mixer shell 1 and the mixer core 2 are fixed with positioning pins to prevent relative rotation, so as to keep th...

Abstract

The invention discloses an EGR (Exhaust Gas Recirculation) mixer of a dual-gas pickup structure. The ERG mixer is characterized by comprising a mixer housing and a mixer core, wherein a first exhaust gas inlet and a second exhaust gas inlet are formed in the sidewalls of the mixer housing, the mixer core is fixedly mounted in the mixer housing, a cavity is formed between the mixer core and the mixer housing and communicated with the first exhaust gas inlet and the second exhaust gas inlet, the mixer core is a venturi tube, a plurality of deflector holes are formed in the throat opening of the venturi tube so that the exhaust gas is capable of going into the mixer core, a fresh air inlet is formed at one end of the mixer core, and the exhaust gas is mixed with the fresh air in the mixer core and then the mixed gas is output via an outlet at the other end of the mixer core to supply gas to an engine. The ERG mixer of the dual-gas pickup structure is characterized in that two independent exhaust gas inlets are provided to realize dual-gas pickup and also can be applied for a sectional exhaust pipe to pick up gas independently, the venturi tube type mixer core is used for improving the mixing effect and effectively solving the problem that the EGR rate cannot be increased when gas is exhausted at a low speed.

Description

technical field [0001] The invention relates to the field of engines, in particular to an EGR mixer with a double air intake structure. Background technique [0002] One way for a supercharged intercooled diesel engine to achieve exhaust gas recirculation (EGR) is to introduce the exhaust gas before the turbo into the intercooler, which is called high-pressure exhaust gas reverse. EGR is beneficial to reduce nitrogen oxides (NO X ) and particulates (PT), without increasing fuel consumption. [0003] The purpose of the engine EGR mixer is to mix the exhaust gas introduced from the exhaust pipe with fresh air after passing through EGR. [0004] Most of the existing EGR mixers use a hole connected to the exhaust gas on the mixer body to guide the exhaust gas introduced from the engine exhaust pipe directly to the intake pipe, and then mix through the mixer core, and finally mix the exhaust gas The exhaust gas is supplied to the intake pipe to achieve the mixing of fresh air ...
