摘要:
A system (40) for starting an internal combustion engine (12) of an automotive vehicle (10) has a controller (54) coupled to a starter/alternator (42). The engine (12) has a crankshaft (50) and a turbocharger (24). The controller (54) initiates the starting of the engine (12) by rotating the crankshaft (50). The rotating crankshaft (50) displaces an amount of air from the cylinders (14) of the engine (12) to rotate the rotor shaft of the turbocharger (21). The turbocharger (25) thus draws in air, compresses the air and provides the compressed air to the cylinders (14). When the engine is started the initial power is increased due to the compressed air.
摘要:
A jump-start assembly 13 for use within a vehicle 10 of the type having a pair of dissimilar batteries 12, 14. Assembly 13 allows the vehicle 10 to be selectively jump-started and electrical charge to be communicated to the battery 14 by the use of a single battery 62, 90.

摘要:
A method for controlling an induction motor using an equivalent circuit model, the equivalent circuit having a real component and an imaginary component, is disclosed. The method instead of measuring a plurality of induction motor parameters, the real and the imaginary component of the induction motor impedance are calculated based on the measured phase currents and voltages. The invention calculates a first control function based on the real component of the induction motor impedance, and a second control function based on the imaginary component of the induction motor impedance, and adjusts the induction motor excitation frequency until the first control function is approximately equal to the second control function. After the excitation frequency is determined, the motor torque is calculated by taking the square of motor voltage in the d-q reference frame. Working with a few control parameters, the present invention achieves a desired maximum torque or a desired peak efficiency with a high tolerance of variation in the control parameters.
摘要:
A hose clamp for forming an air tight seal between a hose and a connector projecting from a housing of an air cooler of a vehicle. The hose clamp including a band which encircles the hose at a location where the hose and the connector overlap and has an adjustable diameter. The hose clamp positioned by a wrap-around hose clamp positioner. The wrap-around hose clamp positioner including flat portions, which contact the outer surface of the hose, and a raised portion where the band passes through a space of the raised portion. The wrap-around hose clamp positioner further including a wrap-around portion and a crimp tab, the wrap-around portion extending over a lip edge of the hose such that the crimp tab pierces through at least the inner surface of the hose.

An electric air conditioner sustain system is disclosed. The electric air conditioner sustain system includes a compressor, an engine and an electric motor. The engine and the electric motor selectively rotate the compressor. When the engine is rotating the compressor and the engine stops, the electric motor is synchronously activated to maintain continuous rotation of the compressor.
