Internal combustion engine i.e. diesel engine, for car, has control element arranged upstream of pressure accumulator in connecting line, where fuel in accumulator passes towards pump line when engine is started after stopping operation

摘要

The engine has a fuel injection system (1) comprising a pre-feeder pump (2) that conveys fuel towards a high-pressure pump (3) via a pump line (4). A control element (13) is arranged upstream of a pressure accumulator (12) in a connecting line (11), where fuel in the accumulator passes under pressure towards the pump line when the engine is started after stopping operation. The control element is implemented as a 2-2-way valve, and the accumulator is implemented as a hydraulic bladder accumulator or a hydraulic piston accumulator. An independent claim is also included for a method for operating an internal combustion engine.
