Abstract
In a fuel injection system for a multi-cylinder internal combustion engine with a cam-controlled high-pressure injection pump for transporting the fuel to a common fuel line (common rail), which acts as high-pressure storage and from which injection lines lead to injection nozzles and which possesses a solenoid valve control that determines the start of the feeding of the fuel, in every exposed fuel line which is an injection line between the common fuel line and an injection nozzle, a solenoid valve which controls the starting point for feeding fuel to the engine is arranged in close proximity to the common fuel line.
Claims7
Fuel injection system for a multi-cylinder internal combustion engine, comprising:
- a high pressure storage element in the form of a common fuel line;
- a high-pressure injection pump for transporting fuel to the common fuel line;
- a plurality of infection nozzles;
- a plurality of injection lines connecting the common fuel line with the injection nozzles;
- and
- a solenoid valve for controlling feeding of high pressure fuel from said common fuel line to said injection nozzles via said injection lines, and determining a respective initial point for each such feeding of fuel, wherein
- the solenoid valve is attached to the common fuel line and interrupts fuel flow in said injection lines at a point immediately adjacent said common fuel line, to control the initial point for feeding the fuel to the engine via a dead volume comprising substantially an entire length of each injection line;
- and
- the injection nozzles are single-acting nozzles.
