Method for detecting characteristic of fuel of direct injecting internal-combustion engine with common rail system, involves realizing height, which characterizes pressure wave caused in common rail system

摘要

The method involves realizing a height, which characterizes pressure wave caused in a common rail system (130). The characteristic of the fuel is closed due to the height. Independent claims are also included for the following: (1) a computer program; and (2) a computer program product.
