What Are the Symptoms of a Damaged Diesel Engine Turbocharger?
1 Answers
Diesel engine turbocharger damage can manifest as blue or white smoke from the exhaust pipe, decreased power, increased fuel consumption, and unstable turbo pressure. Below is relevant information about diesel engine turbochargers: 1. Classification: Turbochargers are categorized by their boosting method into exhaust gas turbochargers, compound exhaust gas turbochargers, and combined turbochargers. After installing a turbocharger, a diesel engine exhibits higher power per liter, lower fuel consumption, reduced emissions, and improved indicated power and effective power, thereby enhancing mechanical efficiency and significantly improving the economic performance in high-load operation. Turbochargers not only expand the power range but also extend the economical operating range under high loads. 2. Working Principle: An exhaust gas turbocharger utilizes the energy from the engine's exhaust gases, which enter the turbine and expand to perform work. The entire power of the exhaust turbine is used to drive the compressor impeller, which is coaxial with the turbine, compressing fresh air before sending it into the cylinders. The exhaust turbine and compressor are typically integrated into one unit, known as the exhaust gas turbocharger. A compound exhaust gas turbocharger connects the exhaust power turbine in series with the exhaust gas turbocharger. A combined turbocharger integrates exhaust gas turbocharging with intake inertia boosting. In this system, in addition to the exhaust gas turbocharger, there is an intake inertia boosting system composed of a surge tank, resonance pipe, and resonance chamber, which utilizes pressure peaks to further increase the intake pressure after boosting.
