Function and technical context

The turbocharger is the component responsible for increasing the pressure of the intake air that enters the cylinders, allowing the engine to burn a greater amount of fuel per cycle and thus develop significantly higher power than it would achieve with natural aspiration. It works within the intake and exhaust system: the turbine is driven by the exhaust gases, which in turn drive the compressor to force pressurized air into the intake manifold. In Volvo Penta TAD and TAMD range industrial and marine engines, the turbo is a critical element in maintaining performance, torque and compliance with emissions regulations; Its deterioration directly affects the response of the engine, fuel consumption and, in serious cases, can cause internal damage due to lack of lubrication or entry of oil into the combustion chamber. This turbocharger, manufactured by SLP (Swedish Lorry Parts), a Swedish specialist in components for Volvo Penta engines, offers the same features as the standard part under catalog reference 1676199.

When to replace this part?

The most common symptoms of a turbocharger in poor condition are: bluish or black smoke from the exhaust, notable loss of power and torque, sharp metallic noise or abnormal whistling noise coming from the turbo, excessive oil consumption or presence of oil in the intercooler and intake ducts. In continuous-duty, high-load marine engines such as those in the TAD and TAMD series, it is recommended to inspect the turbo at each seasonal inspection, checking the axial and radial play of the shaft, the condition of the seals and the clearance of the blades; Preventive replacement at the first signs of wear prevents high-cost secondary breakdowns, such as cylinder scoring or main bearing failure due to oil contamination.
