What role does an air cooler play in a marine engine?

What is a charge air cooler?

A charge air cooler is used to cool engine air after it has passed through a turbocharger but before it enters the engine.

This is their primary function. The goal is to cool the air so that the combustion process within the engine can produce the most power.

It is a heat exchange device used on turbocharged and supercharged (forced induction) internal combustion engines to improve volumetric efficiency by boosting intake air-charge density via isochoric cooling.

A lower air intake temperature offers a denser intake charge to the engine and allows more air and fuel to be combusted per engine cycle, improving engine performance.

The charge air cooler is intended to cool the charged air from 180°C to 220°C to roughly 40°C. It accomplishes this by employing cooled water.

The size of the charge air cooler varies according to the engine. The smallest are intercoolers, which are mounted to automotive or truck engines. The largest are frequently employed on massive marine diesel engines or in power plants. In these conditions, they can weigh several tons.

Vrcooler also makes gas engine air coolers.

The term "charge air cooler" refers to anything that cools the turbocharged air before it enters the engine.
