Abstract
15 A method and an assembly 61 for use with a vehicle 10 having a high voltage battery 42 and an internal combustion engine 12 of the type having a selectively rotatable crankshaft 13 After the high voltage battery 42 receives a donor charge, the assembly 61 causes the crankshaft 13 to be rotated at a slow speed for a predetermined period of time before electrical energy is transferred to the internal combustion engine 12 and before combustion occurs within the engine 12.
Claims12
An apparatus for rotating a crankshaft of an internal combustion engine after a donor charge has been communicated to a battery, said apparatus comprising a first assembly which senses the transfer of said donor charge to said battery;
- and a second assembly which is coupled to said crankshaft and to said first assembly and which rotates said crankshaft at a predetermined speed after said transfer of said donor charge is completed and before combustion occurs within said engine.
A vehicle having an internal combustion engine including a selectively rotatable crankshaft;
- a battery which is coupled to said engine, which supplies electrical energy to said engine, and which has a predetermined amount of electrical charge;
- and an assembly which is coupled to said engine and to said battery, which senses the occurrence of a predetermined loss of charge of said battery, which allows electrical charge to be communicated to said battery, and which rotates said crankshaft at a predetermined speed after said electrical charge has been communicated to said battery and before electrical energy is supplied to said engine.
A method for operating a vehicle of the type having an internal combustion engine, said method comprising the steps of detecting a transfer of a donor charge to a battery;
- and causing said engine to rotate at a predetermined speed before combustion occurs within said engine.
