Abstract: An injection pump having a pump body provided with an inlet conduit supplying an inlet chamber, and a compression chamber downstream from the inlet chamber under which a piston reciprocates to distribute liquid fluid from the compression chamber to an outlet pipe in communication with a common rail circuitry. The injection pump has a valve provided with a resilient cup, located between the inlet chamber and the compression chamber and actuated by an electromagnetic actuator through a pushing rod wherein operation of the valve allows the piston to suck liquid fluid from the inlet chamber into the compression chamber and feed the common rail circuitry or to push back liquid fluid in said inlet chamber and said inlet conduit, in which the pump comprises a filter provided around the pushing rod and located between the valve and the electromagnetic actuator in the inlet chamber.

Abstract: A sound synthesis system and method are provided for an electric or hybrid electric vehicle. The system receives an audio signal from an inverter of the vehicle comprising an analog waveform, a digital waveform, or a parameter. The audio signal from the inverter is synthesized and combined with another audio signal via at least one of combination, superimposition, mixing, multiplication, and adding, and the combined signal is amplified and output as a synthesized audio signal or as a visual display of a waveform of the amplified, combined signal.

Abstract: A method of controlling the operation of a solenoid activated fuel injector, the fuel injector including an actuator including a solenoid, and being adapted to control a needle valve dependent on an activation pulse sent to the solenoid to control the needle valve to dispense fuel.
The method comprises the steps of:
a) determining the minimum drive pulse (MDP1) required for the needle valve to open;
b) determining the closing response of the injector during MDP conditions;
c) determining the total operational time during MDP conditions of the injector;
d)—determining the difference between the value determined from step c) and a stored value;
e) determining the value of the difference between the opening delay of the injector and a stored the opening delay of the reference injector from step d); and
f) controlling the operation based on the parameter at e).-

Abstract: A high-voltage (HV) system is provided including at least one HV component, a passive resistance load coupled to the at least one HV component, a control circuit coupled to the passive resistance load, and an isolated power supply coupled to the control circuit. The control circuit is switchable between a first state in which the control circuit closes an electric circuit connecting the at least one HV component and the passive resistance load and a second state in which the control circuit opens the electric circuit connecting the at least one HV component and the passive resistance load. The isolated power supply controls the control circuit to be in one of the first state and the second state.
