Abstract: A mounting arrangement with a fuel rail having a plurality of fuel injector cups, a plurality of fuel injectors, and a clip. The fuel injector cups include a cylindrical tube defining a longitudinal axis, a fuel rail mounting section disposed at a first end of the tube, and a lip at a second end of the tube. Each of the fuel injectors corresponding to one of the plurality of fuel injector cups. The fuel injectors have a housing with a retention groove. The clip engages both the lip of the fuel injector cup and the retention groove in the housing of the fuel injector to secure the fuel injector to the fuel injector cup and allow the fuel injector to reciprocate along the longitudinal axis.

Abstract: Apparatus for automatically eliminating a sway condition of a trailer towed by a tow vehicle. A hitch connects the trailer to the tow vehicle and has a sensor for providing signals corresponding to the hitch lateral force for operating the trailer brakes.

Abstract: Apparatus for automatically eliminating a sway condition of a trailer having surge brakes and towed by a tow vehicle. The hitch connects the trailer to the tow vehicle and has a reaction wheel for sensing hitch lateral force and for automatically controlling the trailer brakes to eliminate the sway condition.

Abstract: A speed sensor for a vehicle wheel has a rotating tone wheel and a stationary E-shaped magnetic sensor having a sensing pole of square loop magnetic material positioned between two switching poles. A coil is wound on the sensing pole and the poles are magnetized to periodically reverse the flux in the sensing pole as the teeth on the tone wheel alternately pass the switching poles to induce a signal voltage in the coil corresponding to wheel speed and substantially free of noise components due to misalignment and vibrations of the tone wheel upon relative rotation of the tone wheel and magnetic sensor.

Abstract: A speed sensor for a vehicle wheel has a rotating tone wheel with a stationary magnetic sensor having a pair of sensing poles positioned proximate the tone wheel teeth. Coil means are wound on the poles and the poles are magnetized to induce a signal voltage in the coil means corresponding to wheel speed. The poles are phased relative to the teeth on the tone wheel to reduce noise voltage components in the wheel speed signal voltage due to axial misalignment and vibration of the tone wheel. The poles may be phased 180.degree. relative to one another with respect to the teeth on the tone wheel so that one pole is in registry with a tooth when the other pole is in registry with a space between two teeth. With this arrangement the combined reluctance of the poles is approximately constant.
