Filtration system for marine and heavy duty engines

Back to Blog

Diesel engine filters are critical components that help maintain fuel quality and protect the engine from contaminants that could cause damage.

5 types of filtration systems in diesel engines

  1. Primary fuel filter

This filter is located in the fuel line before the injection pump. Its main function is to remove large particles, such as sediment and rust, which could damage the injection pump and injectors. Primary filters are usually of the water separator type.

  1. Secondary fuel filter

This filter is placed after the injection pump and before the injectors. Its purpose is to filter out smaller particles and debris that could damage the high-pressure components of the fuel system, such as the injectors.

  1. Water separator filter

Some diesel engines use an additional water separator that focuses on removing water from the fuel. This water filtration system is essential to prevent the formation of microorganisms and corrosion in the fuel system.

  1. Diesel Particulate Filter (DPF)

The DPF is a crucial component in modern diesel engine exhaust systems. Its main function is to capture and retain fine soot particles from the exhaust gases.

  1. Diesel Oxidation Catalyst (DOC)

Some diesel exhaust systems incorporate a DOC to assist in the oxidation of unburned hydrocarbons and carbon monoxide. It works in conjunction with the DPF to reduce pollutant emissions.

It is important to follow the engine manufacturer’s recommendations for when to replace each filter and, of course, to perform regular preventive maintenance to ensure optimum engine performance.

In addition, the use of high quality fuel will contribute significantly to the life and efficiency of the filtration system. That is why we at Talleres Nasio recommend the use of Fleetguard filters.
