Definitions

  • the object of the invention is a method to operate a working on the Otto principle Provide internal combustion engine in lean operation, which secured sufficient vacuum in the intake pipe provides to reinforce a brake system without to cause additional fuel consumption and without additional sensors for monitoring the vacuum in the Intake manifold.
  • the method according to the invention does not require any additional ones Switches or sensors, since a detection of the speed of the Internal combustion engine with modern internal combustion engine anyway is available. The same applies to devices for recording the accelerator pedal position and for detecting the actuation of the Brake pedal. These facilities are included anyway Motor vehicles according to the prior art available.
  • the accelerator pedal position and actuation of the brake pedal can Need for brake power assistance can be recognized and the Throttle valve of the internal combustion engine are controlled so that stoichiometric operation is achieved and consequently a sufficiently large negative pressure in the Intake pipe prevails. Due to the throttling effect of the Throttle valve in the intake pipe is also the Engine braking effect of the internal combustion engine increases what has a positive effect on the deceleration of the motor vehicle.
  • the stoichiometric operation of the Internal combustion engine by measuring the of the Air mass and internal combustion engine Plausibility checks are monitored. This surveillance increases the reliability of the method according to the invention and can be available anyway due to the appropriate use Facilities such as an air mass sensor without additional costs can be achieved.
  • the specific fuel requirement of the internal combustion engine can be further minimized if after falling below a speed limit for a fuel cut-off Internal combustion engine is operated in lean operation.
  • the method can further be provided that the actuation of the brake pedal is detected by two redundant switches.
  • the accelerator pedal is in the rest position and the brake pedal is applied is a situation given in which the motor vehicle is to be braked and thus support the braking by the Vacuum in the intake pipe is desirable. Consequently is present according to the inventive method of these three conditions the throttle device to one minimum required value is closed or the Internal combustion engine with a stoichiometric air-fuel ratio or with overrun cutoff of the is operated so that the desired vacuum in Intake pipe adjusts. As a result, one stands Brake booster available and always, if the driver of the vehicle wants to delay this. As Throttle device can also control the valve Serve gas exchange valves with variable valve lift.
  • the invention can additionally Procedures are monitored by that of the Internal combustion air mass is measured and by carrying out plausibility checks. Thereby can malfunction of sensors, actuators or the Control unit of the internal combustion engine can be recognized and in so-called emergency programs can be switched.
  • the method according to the invention can be known per se Process for operating one according to the Otto principle working internal combustion engine are superimposed so that the known methods for operating a the internal combustion engine working according to the Otto principle unchanged can continue to be used and by the invention Procedures can be improved.
