High-temperature-resistant gas inlet manifold

Abstract

The invention provides a high-temperature-resistant gas inlet manifold which comprises an engine gas inlet throttle valve, a gas inlet manifold resonant cavity, a plurality of gas inlet manifold branches and a connecting flange, wherein the throttle valve, the gas inlet manifold resonant cavity, and the plurality of gas inlet manifold branches are made of high-temperature-resistant rubber; and the high-temperature-resistant rubber comprises the following components in parts by weight: 100 parts of fluororubber, 15 parts of barium sulfate, 20 parts of calcium silicate, 6 parts of magnesium oxide, 6 parts of iron oxide red, 0.8 part of carbon black N774, 0.8 part of palm wax, 0.7 part of WS280 and 0-1.5 parts of calcium hydroxide. The high-temperature-resistant gas inlet manifold disclosed by the invention is made of high-temperature-resistant rubber, and has good physical and chemical properties, and further improves reliability of the whole equipment and prolongs service life of the whole equipment.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an engine intake manifold. Background technique [0002] In my country, the development of the automobile industry and plastic manufacturing technology is advancing by leaps and bounds. Engine parts made of metal are gradually replaced by engine parts made of plastic represented by the intake manifold. As one of the most critical components of the engine, the intake manifold is used in automobiles. It has been widely used in the industry, and its core function is to provide a fully and uniform mixture for each cylinder of the engine, which is a key factor affecting engine power and fuel consumption. [0003] Due to the high speed of the vehicle, the temperature of the parts around the engine is gradually rising, so it is necessary to improve the heat resistance of the engine and the surrounding rubber products. If the engine intake manifold cannot achieve the effect of high temperature ...
