  • Patent number: 8788180
    Abstract: An object of the present invention is to suppress the dispersion of EGR gas amount between cylinders when the stuck open state arises in an EGR valve in an EGR apparatus for an internal combustion engine in which an EGR passage is branched on an intake system side into a plurality of EGR branch pipes, and the respective EGR branch pipes are connected respectively to intake branch pipes provided for the respective cylinders. In the present invention, if the EGR valve is stuck open, the exhaust pressure is reduced in an exhaust system of the internal combustion engine, while suppressing an amount of decrease in a driving force of a vehicle which carries the internal combustion engine within an allowable range.

  • Patent number: 8096289
    Abstract: Separation of an air compression supply port from exhaust gas recirculation (EGR) in internal combustion engines. In one aspect, an air intake connector includes an entry port for an EGR gas, and an air intake elbow is connected to the air intake connector, the elbow receiving air. The elbow includes a first passage for routing a first portion of the air to the air intake connector to be mixed with the EGR gas, and a second passage for routing a second portion of the air to the air intake connector and out an exit port to an air compressor. The second passage is attached to the elbow and extends through a bend in the elbow.

  • Patent number: 8056340
    Abstract: An EGR mixer comprises an upstream conduit section having a contracting flow area in a direction of air flow through the mixer, a downstream conduit section having an expanding flow area in the direction of air flow through the mixer, a slot formed in the downstream conduit section for admitting exhaust to the air flow, and an abrupt flow-expanding ridge disposed between the upstream and downstream conduit sections. With the EGR mixer configured in this manner, recirculated exhaust may be effectively homogenized into an intake air flow with reduced drag.

  • Patent number: 8051843
    Abstract: Exhaust gas inlets for introducing exhaust gas from an EGR pipe, on the right bank side, and exhaust gas inlets for introducing exhaust gas from the EGR pipe, on the left bank side, are both formed in low-pressure regions. The exhaust gas inlets are formed at positions where the pressure of the intake air flowing through branch pipes on the right bank side and the pressure of the intake air flowing through branch pipes on the left bank side are both low and substantially equal. Accordingly, exhaust gas is introduced evenly into cylinders in the right and left banks. These inlets are not formed at positions in a common intake passage from which branch paths branch off, that is, positions upstream of a surge tank. Accordingly, the response to introduction of exhaust gas is not deteriorated but is maintained.

  • Publication number: 20110232614
    Abstract: An intake body, systems, and method for reducing acoustic resonance in pressure tap passages include determining and/or setting the length of the drilling tap passages to a value such that the natural frequency of each pressure tap passage is outside of or does not substantially overlap with operational frequency content of an air stream in the intake body. The intake body, systems and method reduce the possibility of exciting the natural acoustic frequencies of the pressure tap passages, and can lead to improved signal-to-noise ratio when detecting EGR flow using a delta-P measurement system.

  • Patent number: 7971578
    Abstract: The present invention relates to an exhaust gas recirculation (EGR) valve for a vehicle. The EGR valve includes a valve housing connected to an exhaust line for discharging exhaust gas therethrough, having a flow line with an inside area divided for taking and re-circulating a portion of the exhaust gas to a suction manifold, a driving unit on one side of the valve housing, and a valve unit mounted in a flow line of the valve housing for receiving driving force from the driving unit directly to control flows of the exhaust gas flowing through the flow line at the same time individually, thereby making stable control of the exhaust gas flowing through the EGR valve, preventing damage caused by the high temperature exhaust gas, and preventing the exhaust gas from leaking to an outside of the EGR valve.
