Abstract: A common rail system for a fuel injection system of an internal combustion engine, the common rail system comprising: a high pressure pump for receiving fuel from a fuel tank; at least one fuel injector for delivering fuel to the internal combustion engine; a common rail for receiving fuel from the high pressure pump through a flow path of the common rail system that connects the high pressure pump to the common rail, the common rail comprising a fuel reservoir in fluid communication with a common rail inlet and in fluid communication with the one or more fuel injectors; and a filter provided in the flow path. The filter is configured to filter fuel so as to prevent particulate matter from entering the common rail. The common rail system comprises only one filter.
