Function and technical context

The turbocharger is the component responsible for forcing a greater amount of compressed air into the engine cylinders, increasing combustion efficiency and power delivered. It works integrated into the intake and exhaust system of the diesel engine, taking advantage of the energy of the exhaust gases to drive the turbine that compresses the inlet air. In continuous duty marine engines such as the Volvo Penta TAD420VE series, the turbo operates under very demanding temperature and rotation speed conditions. A damaged turbocharger causes a notable loss of power, increased fuel consumption, excessive emission of black or bluish smoke and can lead to serious damage to the engine unit if it is not replaced in time. This unit is manufactured by SLP — Swedish Lorry Parts, a Swedish specialist with extensive experience in spare parts for Volvo Penta engines, guaranteeing fit and performance in accordance with the engine specifications.

When to replace this part?

The most common symptoms of a worn or failed turbo include progressive loss of thrust under load, presence of blue or black smoke in the exhaust, unusual metallic noise coming from the turbocharger housing, and in advanced cases, high oil consumption due to leaks through the turbine shaft seals. In marine engines with intensive use, it is recommended to inspect the turbo during each seasonal maintenance, paying special attention to the axial play of the shaft and the condition of the vanes. Replacing the turbocharger preventively at the first signs of wear avoids chain failures that can affect the cylinder head or engine block, with a much higher repair cost.
