Many of today’s modern engines have two chargers that help to improve engine efficiency, and for which insulation blankets have an important role to play—turbochargers and charge-air coolers.
To understand how insulation can help you get the best performance from your engine, you first need to know how turbochargers work. The function of a turbocharger is to increase the mass of air that enters the engine, which leads to a greater air/fuel mix and boosts the horsepower. This is achieved by an internal turbine and corresponding compressor. The turbine, which can spin at speeds over 200,000 rpm, drives a compressor, which increases the amount of air entering an engine’s cylinders. Because the turbocharger’s turbine is powered by the engine’s own exhaust and because of the rapid rpms, turbochargers run at extremely hot temperatures.
The extreme heat generated by turbochargers can stress sensitive engine parts in the piston and cylinder area, and have a detrimental effect on surrounding engine components and employee safety.
Unlike turbochargers, charge air coolers run cold. Charge air coolers work to cool the compressed air that leaves the compressor before the air enters the engine. The increased density of the colder air means that more air can fit into the engine, for greater power. Charge air coolers thus improve the efficiency of the turbocharger and engine by allowing a greater mass of air to enter the engine at one time.
Insulation blankets are used in conjunction with both turbochargers and charge air coolers. For turbochargers, the blankets keep the heat from escaping the turbochargers and from entering the surrounding engine components. For charge air coolers, insulation blankets are found on the hot piping that leads from the turbocharger to the cooler, in order to protect personnel who might be in the area.
