Fuel injection system with common rail

摘要

The fuel distributor or common rail (1) has a pressure accumulator (2) from which a pressure line (4) extends radially and is connected to the intake of a fuel injection valve (9). In the fuel distributor, at least one fluid line is arranged parallel to the pressure accumulator, and thermally coupled to the pressure accumulator. The fluid line may be a drain line (5) from which a leakage line (7) runs parallel to the pressure line (4). The leakage line is connected to the outflow (11) form the fuel injection valve.
