Integrated intake manifold

Abstract

The invention discloses an integrated air intake manifold which comprises an air intake manifold body and an intercooler; an air duct, a cooling chamber and air outlet passages are arranged in the air intake manifold body; the air outlet passages all communicate with the air duct through the cooling chamber; the intercooler is fixedly arranged in the cooling chamber; and the air duct is internally provided with an air deflector used for guiding air into the cooling chamber. According to the integrated air intake manifold disclosed by the invention, air inflow of each air outlet passage and each cylinder of an engine is uniform, air cooling effect is good, increase of air density is facilitated, the effective output power and torque of the engine are improved, and the problems of crude operation of the engine, high working noise, non-uniform work of each cylinder and short service life of the engine are avoided.

Description

technical field [0001] The invention relates to an integrated intake manifold. Background technique [0002] With the development of my country's automobile industry, more and more attention has been paid to its emission regulations, fuel economy and comfort. For this reason, technologies such as supercharging and in-cylinder direct injection are more and more widely used in gasoline engines. When the air passes through the compressor After supercharging, its temperature will rise significantly. In order to further increase the air density after supercharging and at the same time suppress the occurrence of knocking, cooling equipment is needed to cool down the air. Uniformity and air density are particularly important, and uniform air intake in each cylinder of the engine is an important prerequisite for stable engine operation. The intake manifold is used as the intake device of the engine, and the outlet ports are arranged in multiples corresponding to the cylinder block of...

AI Technical Summary

Problems solved by technology

The intake manifold is used as the intake device of the engine, and the outlet ports are arranged in multiples corresponding to the cylinder block of the engine, and most of them are arranged in a straight line. In order to save space, the direction of the intake port of the intake manifold is usually parallel to the direction of the arrangement of the outlet ports. Therefore, there is a change in the flow direction of the air when it enters the air outlet from the intake port, which affects the uniformity of the air intake of each air outlet. The traditional intake manifold and intercooler are set independently of each other, with poor cooling effect and low control density. It greatly affects the effective output power and torque of the engine, and also causes problems such as rough engine work, loud work noise, uneven work of each cylinder, and shortened engine life.
