WHY ARE TURBO INTERCOOLERS IMPORTANT FOR YOUR ENGINE

图片
Turbocharging remains one of the best solutions for improving a car’s capacity. The issue is that turbocharged engines produce significant heat, which results in lower performance levels and potentially severe engine damage. This excessive heat leads to poor power output and reduced efficiency, making you frustrated with sluggish power.   What is a Turbo Intercooler? Turbo Intercoolers  add more value to automobiles with turbochargers. They cool the air that the turbocharger pumps so that it is in the proper condition when admitted into the engine. When the turbocharger compresses the air, it gets hot, reducing an engine’s efficiency and power. The intercooler then cools this hot, compressed air to a cooler temperature, which is supplied to the engine. Lowering the air’s temperature increases density, so more oxygen gets trapped in the engine. This results in enhanced combustion, enhanced proponents, and overall upgrades in power and efficiency.
