摘要:
Fuel level sensor (28) for sensing the level of liquid fuel in a fuel tank, the sensor comprising: a base frame (30) to be fixedly mounted relative to the tank; a pivoting arm (32) with pivotally connected to the base frame (30) and carrying a float (34); a variable resistor assembly (36) configured for translating the position of the float (34) into an electric signal; characterized in that the pivoting arm (32) and the base frame (30) are pivotally connected by a snap-fit connection (44); and in that the variable resistor assembly (36) comprises a resistor circuit (38) affixed to the pivoting arm (32) as well as contact fingers (40) fixedly mounted to the base frame (30) and configured to be in contact with the resistor circuit (38).
摘要:
A multi-charge ignition system including a spark plug control unit adapted to control at least two coil stages so as to successively energise and de-energise said coil stage(s) to provide a current to a spark plug, said two stages comprising a first transformer (T1) including a first primary winding (L1) inductively coupled to a first secondary winding (L2); a second transformer (T2) including a second primary winding (L3) inductively coupled to a second secondary winding (L4); characterised in including auxiliary primary winding (L5) connected from the common high side of the primary winding in series to an auxiliary secondary winding (L6), the other end of said auxiliary secondary winding (L6) electrically connected to ground/low side, and including switch means Q3 adapted to selectively allow current to pass through said auxiliary windings.
摘要:
A method of controlling a fuel injector including a solenoid actuated valve arrangement, said valve arrangement including an armature adapted to be in contact with a proximal end of a valve needle comprising applying a current profile to said solenoid; wherein said profile comprises a peak phase where the current is ramped to a peak/demand value, followed by a transition phase, where the demand value of current is set to a value substantially lower than the peak value, followed by a by-pass phase where the current is set/ ramped to a by-pass/demand level.
摘要:
A fluid flow guide member (16) of a heat exchanger (10), adapted to be traversed by a fluid flow (F). The guide member (16) is made from a corrugated metallic strip (18), the width (W) of which extends along a transversal axis (T) from a leading edge (26) to a trailing edge (28). The leading edge portion (30) of the guide member (16) is provided with slit louvers (34) adapted to deviate the flow (F) and, the trailing edge portion (32) is free of slit louvers.
