摘要： A method of estimating temperature in an engine including estimating metal temperatures at each of a plurality of nodes and estimating a coolant temperature. The method further includes detecting a measured coolant temperature and determining a gain based on a difference between the estimated coolant temperature and the measured coolant temperature. The method adjusts the metal temperatures at each of the plurality of nodes based on the gain. The method estimates the metal temperatures of engine components without temperature sensors.

摘要： The present invention relates to a start-stop “mild hybrid” vehicle with a starting system which utilizes traditional engine and transmission architecture. The present invention separates the pinion actuator solenoid from the starter motor power switching circuit. A power relay is provided to switch the starter motor. The pinion gear in the present invention is pre-shuttled to, and held in mesh with, the flywheel ring gear during engine stop conditions. A “prime current” is then applied to the power relay just below that which is required to energize the power relay. Upon request for an engine start, the current will increase to energize the relay and allow the starter motor to spin. A significant amount of time lag is thusly removed from the starting system permitting an expedient restart and launch. The pinion actuator solenoid in this invention may also have two coils which may be selectively energized.

摘要： A cooling system has a diverter valve to selectively control the flow of coolant through an internal combustion engine having a cylinder block with a cooling jacket and a cylinder head mounted on the block with a cooling jacket. A controller, responsive to the temperature of the block and the head, controls the diverter valve and a water pump to provide adequate coolant flow through the head and the block as needed to maintain optimal operating temperatures. After the engine is shut off, the controller continues to operate the water pump and a cooling fan to continue to cool the engine for a period of time.

摘要： An engine starting system that regulates a position of a pinion gear of a starter motor between an engaged position and a disengaged position includes a solenoid pinion armature (SPA) that is coupled to the pinion gear and that is movable between a first position and a second position to move the pinion gear between the disengaged position and the engaged position. A damper dampens a velocity of the SPA during movement of the SPA to the second position to inhibit noise generation.
