Title: Dennis McDonald: Innovator in Fuel System Technologies
Introduction
Dennis McDonald is a notable inventor based in New Boston, MI (US). He has made significant contributions to the field of automotive technology, particularly in fuel system diagnostics and engine control systems. With a total of 4 patents to his name, McDonald continues to push the boundaries of innovation in his field.
Latest Patents
One of McDonald's latest patents is focused on the detection of fuel system problems. This method involves monitoring a feed-forward table of a fuel pump controller that is electrically connected to a fuel pump. The system compares the actual fuel injector rail pressure, measured by a rail pressure sensor, to a desired pressure associated with the feed-forward table. If discrepancies arise, the feed-forward table is adjusted, and a fuel system error is signaled if the adjusted table differs from the initial one.
Another significant patent is the system and method for determining engine stop position. This invention includes an engine tracking subsystem that senses the rotation of the crankshaft to determine engine position. Upon receiving an engine shutdown signal, the throttle is controlled to lower the air pressure in the intake manifold, effectively reducing engine reversal torque. This innovation ensures that the last engine position is stored for the next startup, enhancing the efficiency of engine management.
