Abstract

The invention relates to a method for adapting the performance of a prefuel pump of a motor vehicle having a common rail injection system and an internal combustion engine. After switching on the ignition and before starting the internal combustion engine, an adaptation value assigned to the prefuel pump describing its individual behavior is determined and stored. After starting the internal combustion engine, this stored adaptation value is taken into account when determining the control signal for the prefeed pump.

Description

technical field

[0001] The invention relates to a method for adapting the performance of a prefuel pump of a motor vehicle having a common rail injection system and an internal combustion engine. Background technique

[0002] Common rail injection systems are known. This is an injection system for a combustion engine, in which a high-pressure pump raises the fuel to a high pressure level. Fuel under pressure fills a pipe system that is always under pressure while the engine is running.

[0003] Such a common rail injection system is known from DE 10 2006 023 470 A1. The system described there has a high-pressure fuel pump for delivering fuel, a high-pressure fuel accumulator connected to the high-pressure fuel pump for storing fuel at an injection pressure relative to the environment of the common rail injection system, An injector connected to the high-pressure fuel accumulator for delivering fuel to at least one combustion chamber, and an injector for returning fuel fro...
