Estimating the term…
A system for bringing an internal combustion engine to a stop at a predetermined angular position of an engine shaft, such as a crankshaft or a camshaft, with respect to the engine's valves. The optimum shaft stop position is the point wherein the fewest lifters are collapsed the least amount. Exemplary methods and apparatus include using the engine starter motor to jog the stopped engine to the desired position; using the engine alternator to impose a variable electromagnetic load on the engine to bring the engine to a stop at the desired position; using variable firing of cylinders to control the deceleration profile to bring the engine to a stop at the desired position; and providing one or more detents formed in the shaft and using a shaft follower to control the stop position of the shaft by engaging the follower into a detent.
A system for causing an engine shaft in an internal combustion engine to stop after engine shutdown at a predetermined angular position of the shaft with respect to the engine's valves, said system comprising:
A method for causing a shaft in an internal combustion engine to a stop at a predetermined angular position of the shaft with respect to the engine valves, said method comprising the steps of:
A vehicle comprising an internal combustion engine including a system for causing an engine shaft in said engine to a stop at a predetermined angular orientation of said shaft with respect to the engine's valves, said system including:
A method for reducing cold start engine noise when starting an internal combustion engine, comprising the steps of:
