Title: Control system for fuel injector in vehicle engine
Inventor: TRAUTMANN WILHELM
IPC: F02M37/08
Filed: 1993-12-09
Abstract: The injectors are connected to a processor control (7) which generates the opening pulses for the fuel injection as well as the lengths of the pulses and the torque demands. The fuel pump (6) supplying the injectors is driven in relation to the fuel pulses so that for small torque demands the pump power is correspondingly reduced while for large torques the pump power is increased.If the fuel flow control includes a return flow of excess fuel then this is reduced to a minimum. The fuel pump pulses are multiplied by a control factor which covers the excess amounts. The injector valve drive pulses are multiplied by a set factor depending on the pump characteristic and the required torque conditions.

Title: Automatic load adjuster for vehicle IC engine
Inventor: OPPERMANN ROLF
IPC: F16H55/08
Filed: 1994-02-03
Abstract: A load-adjuster for a car has a pinion (13) driven by a servomotor and held on a pivoted lever against the force of a spring. The pinion engages a gear (16) that is part of the adjustment drive. The servomotor can rotate in both directions and the teeth of the pinion and the gear are asymmetrical so as to give a shallow meshing angle and in both rotation directions, no thrust forces appear on the teeth such as would cause the lever (15) to tilt into the disengagement position.  Because of the asymmetry of the teeth, the resulting force on the lever caused by tooth contact is directed along the lever axis, or possibly slightly displaced on the side of the solenoid (7).

Title: Motor vehicle braking lights flasher
IPC: B60Q1/44
Filed: 1994-12-28
Abstract: A device to cause the brake lamps of a vehicle to flash has the flashing frequency determined by a brake pressure sensor. The flashing is defined as a periodic interruption of the normally constant lamp illumination for such a time that the lamps become fully extinguished before re-illuminating. At zero and low brake pressures, the flashing frequency is zero and it increases as the brake pressure increases. With increasing brake pressure the frequency is immediately raised, but it is only slowly reduced with decreasing brake pressure. There is a condenser between the current source and the frequency controller. The controller has its own power source.
