The intercooler is a heat exchanger which cools the compressed air feeding the engines of cars equipped with a turbocompressor. Turbocompressor supercharging, an ever more widespread system, allows to increase the power of an engine, even if of small capacity, by compressing a larger amount of air into the engine hence a greater amount of fuel.

During compression, the air tends to warm up and its density is reduced. This partly thwarts the effect of compression itself. The intercooler’s effect is exactly that of reducing the temperature of compressed air allowing to fully exploit supercharging. The attention paid to reducing emissions and fuel consumption leads to the search for components that enhance engine efficiency and the intercooler is precisely one of these. DENSO owns a company dedicated to the development of intercoolers and avails itself of climatic chambers and road-tests to check the efficiency of its systems under running conditions that are as close as possible to the real conditions under which customers use their cars.
