Embodiment Construction

[0027] In the following description of the embodiments of the present invention, similar items in the respective embodiments are denoted by the same reference numerals.

[0028] figure 1 A motor vehicle 1 of an embodiment of the invention is schematically depicted. The motor vehicle 1 comprises an engine 2 and a fuel system 3 for supplying fuel to the engine 2 . figure 2 The fuel system is described in more detail. figure 2 is a flowchart of the fuel system 3 according to the first embodiment of the present invention. The fuel system 3 comprises a fuel tank 4 , a feed line 5 and a fuel line 6 arranged to conduct fuel between the fuel tank 4 and the feed line 5 . The feed line 5 is connected to a high pressure pump 7 adapted to supply fuel to the engine 2 at high pressure. Thereafter, the fuel from the high-pressure pump is distributed into the engine in a known manner. The fuel system 3 also comprises a feed pump 8 arranged on the fuel line 6 and adapted to pump fuel fr...

Abstract

A motor vehicle (1) comprising an engine (2) and a fuel system (3) for supplying the engine (2) with fuel is described. The fuel system (3) comprises a fuel tank (4), a fuel line (6) arranged between the fuel tank (4) and a feed line (5) connected to the engine (2), and a water separating filter (9) arranged on the fuel line (6) to separate water fro the fuel, whereby the water separating filter (9) comprises a drain (10) for water. The drain (10) is connected to the fuel tank (4) by a drain line (11) in order to lead water from the drain (10) to the fuel tank (4).

Description

technical field [0001] The invention relates to a motor vehicle having a fuel system and a water separation filter for separating water from the fuel. Background technique [0002] Internal combustion engines in motor vehicles used in general transportation run on common commercial fuels that contain pollutants. Contaminants in the fuel can completely damage the engine or at least impair its performance. Contaminants can be in the form of particles, gases or liquids. Contaminants in the fuel can impair the performance of the engine to the point where the engine cannot run. It is well known, for example, that even small amounts of water in diesel fuel can hinder diesel engine operation. Particles in the fuel can damage the engine by causing increased wear, or stop the engine from running by clogging the fuel lines in the engine. [0003] Particles in the engine can be filtered out by means of particle filters known to those skilled in the art. Particles from the particul...
