Embodiment Construction

[0009] The principle and structure of the present invention will be described in detail below in conjunction with the accompanying drawings and through embodiments.

[0010] The diesel engine air intake connection device has the following structure: the intake pipe installation surface 1 is perpendicular to the EGR valve installation surface 2 and the exhaust connection pipe 3, and the three channels communicate with each other. A horizontal navel 4 and a vertical navel 5 are cast on the exhaust pipe, and the centers of the two navels are provided with processing holes. The horizontal navel is used to install the intake air temperature sensor and pressure sensor; the vertical navel is used to install the EGR. Bracket for control valve harness and pressure sensor harness.

[0011] The installation surface of the intake pipe is provided with three equal-thickness bosses distributed asymmetrically, and the centers of the three bosses are all processed with through holes 6-1 to 6-...

Abstract

The invention discloses a diesel engine air inlet adapter pipe device, which is structurally characterized in that an air inlet pipe installation surface is perpendicular to an EGR (Exhaust Gas Recirculation) valve installation surface and an exhaust adapter pipe, and three channels are interconnected. Horizontal and vertical lug bosses are casted on the exhaust adapter pipe; processing holes are formed in the centers of the two lug bosses; the horizontal lug boss is used for installing an air inlet temperature sensor and a pressure sensor; the vertical lug boss is used for installing supports of an EGR control valve wiring harness and a pressure sensor wiring harness. According to the specific installation requirements, three even-thickness bosses distributed asymmetrically are arranged on the air inlet pipe installation surface, and through holes are processed in the centers of the bosses. By utilizing the device, an air inlet pipe and an exhaust pipe in an engine EGR system are connected, and an EGR valve is ingeniously arranged between the two pipes, so that an air inlet pipeline and an exhaust pipeline of the EGR system can be effectively shortened. The device solves the reasonable arrangement problem of the EGR control valve on an engine, so that the boundary dimension of the engine is effectively controlled, and a relatively wide space is provided for assembling the engine.

Description

technical field [0001] The invention belongs to engine components, and in particular relates to an engine air intake connection device. Background technique [0002] With the promulgation and implementation of national environmental protection regulations, the emission requirements for automobiles are becoming more and more stringent. In order to meet the National III emission standards, in addition to the high-pressure common rail technology, the exhaust gas recirculation (EGR) technology is currently the key to energy-saving and emission reduction of automobile engines. main measure. The layout scheme of the EGR control valve on the engine body is related to the rationality and reliability of the installation of the entire EGR system. At the same time, the current users have higher and higher requirements for the driving comfort of the car, which means that more and more auxiliary parts are added on the engine body. However, the space for engine vehicle assembly is limit...
