Internal-combustion engine i.e. petrol engine, controlling method, involves closing exhaust valves of high pressure accumulator until idle condition of engine, and continuously operating high-pressure pump after stoppage requirement

摘要

The method involves supplying a high pressure accumulator (17) with fuel by a high-pressure pump (14). A run-out of an internal-combustion engine (19) takes place on a stoppage requirement, and exhaust valves (18) of the high pressure accumulator remain closed until an idle condition of the internal-combustion engine. The high-pressure pump is continuously operated after the stoppage requirement. The high-pressure pump is mechanically driven by the internal-combustion engine. The pressure in the high pressure accumulator is increased during the run-out. Independent claims are also included for the following: (1) a device i.e. electronic control unit or internal-combustion engine for executing control method (2) a computer program with program code implemented in a computer for controlling an internal-combustion engine.
