Is There a Problem If the Turbocharger Glows Red?
1 Answers
Turbocharger glowing red is not a big issue. It is normal for a turbocharger to glow red under prolonged high-load conditions, especially in large trucks. However, if it glows red too easily, it might indicate a cooling problem. Prolonged glowing can lead to blade deformation, reduced compression efficiency, and even potential shaft burning. Below is some relevant information about turbochargers: 1. A turbocharger consists of two parts: a compressor turbine and an exhaust turbine. The working principle of a turbocharged engine is quite simple. When the engine reaches a certain RPM, the exhaust gases have enough energy to spin the exhaust turbine, which in turn spins the compressor turbine. This allows the compressor turbine to compress air and force it into the cylinders. 2. After prolonged operation, the exhaust turbine can reach extremely high temperatures, causing it to glow red. Even some naturally aspirated engines may have their exhaust headers glow red after long-distance driving, which is normal. 3. If the turbocharger glows red, you can let the engine idle for a while to allow the turbocharger to cool down. Opening the engine hood during this time can help dissipate heat more quickly.
