Fatigue and wear indicator construction method for fuel injection device in car, involves calculating instantaneous damaging values, and cumulating values for obtaining value indicating fatigue and wear of fuel injection device

摘要

The method involves measuring physical magnitudes e.g. injected fuel temperature, representing mechanical and/or thermal solicitations to which a fuel injection device is subjected. Instantaneous damaging values are calculated according to a predetermined damaging rule and the measured physical magnitudes. The instantaneous damaging values are cumulated for obtaining a value indicating fatigue and wear of the fuel injection device. Independent claims are also included for the following: (1) a method for suppressing automatic stops and starts of an engine (2) a data recording medium comprising instructions for executing a method for suppressing automatic stops and starts of an engine (3) a constructor for constructing a fatigue and wear indicator (4) a device for suppressing automatic stops and starts of an engine.
