Materials used in automotive intercooler hoses.

With the development of the automotive industry and increasingly stringent environmental protection requirements, the combustion gases containing oil and alcohol in the medium and environment used in automobile engines enter the entire engine system through the crankcase. However, in the car intercooler hose is also a lot of attention to everyone, let’s take a look at the materials used in the car intercooler hose.

The intercooler is one of the important components of turbocharging. When compressing air, too high an air temperature will cause the air to expand, which will directly affect the amount of mixture entering the cylinder. Therefore, it is necessary to cool the compressed air before entering the cylinder to increase the amount of mixture entering the cylinder, so that the inflation efficiency is increased and the engine power is enhanced. The intercooler plays the role of cooling the air, so that the high-temperature air is cooled by the intercooler and then enters the engine.

The use temperature of the automobile intercooler intake hose is as high as 150 °C ~ 275 °C, and its material must meet excellent high and low temperature performance, good oil resistance and weather resistance.

In silicone rubber, acrylic rubber, fluorosilicone rubber, fluoroelastomer and other materials with excellent high temperature resistance, the material that does not have good oil resistance is silicone rubber, but silicone rubber is the cheapest of these four materials, of which the price of acrylic rubber, fluorosilicone rubber, fluoroelastomer is about 2 times, 17 times and 6 times of silica gel, respectively. In this way, if the rubber material in the intercooler intake hose in the closed-structure oil and gas separation system chooses fluorosilicone rubber and fluororubber, it does not have a cost advantage, but the high temperature resistance of acrylate rubber is only about 175 °C, which is only suitable for engines with small horsepower, that is, an exhaust volume of 1.5T.

With the development of the automotive industry, it has developed from traditional materials to new modified materials, and the application of high-reliability and low-cost polymer materials has promoted the further development of the automotive industry. I hope that the information about the materials used in automotive intercooler hoses will be helpful.
