Function and technical context

The turbocharger is the component responsible for compressing the intake air before introducing it into the cylinders, increasing the density of the mixture and, with it, the power and efficiency of the engine. It works within the intake and exhaust system: it harnesses the kinetic energy of the exhaust gases to drive a turbine that drives the air compressor. In Volvo Penta TD, TID, TWD and TAD series marine diesel engines, the turbo is a critical element to maintain the engine's rated performance; Its degradation causes a progressive drop in power, increased fuel consumption and the emission of black or blue smoke from the exhaust. Manufactured by SLP — Swedish Lorry Parts, a Swedish specialist in components for Volvo Penta engines, this turbo guarantees performance in accordance with the engine design specifications.

When to replace this part?

The most common symptoms of a damaged turbocharger include a noticeable loss of thrust or slow acceleration response, presence of oil in the intake manifold or intercooler, a high-pitched metallic noise from the operating turbo, and excessive smoke from the exhaust pipe. It is recommended to inspect the turbocharger during each seasonal maintenance and replace it as soon as there is play in the turbine shaft or signs of oil contamination, since a turbo with excessive play can release metal fragments into the engine and cause serious damage to the cylinder head and pistons. Acting preventively at the first symptoms avoids major breakdowns that can leave the boat inoperative on the high seas.
