US Patent:

8433496, Apr 30, 2013
Filed:

May 18, 2010
Appl. No.:

12/782086
Inventors:

Mark D. Carr - Fenton MI, US
Michael N. Kotsonas - Highland MI, US
Michael J. Lucido - Northville MI, US
Dean R. Kwapis - White Lake MI, US
International Classification:

F02M 7/28
F02D 41/30
US Classification:

701103, 701111, 701112, 1231799, 123481, 123435
Abstract:

A control system includes an engine enable module and a fuel control module. The engine enable module determines whether predetermined operating conditions of a spark ignition direct injection (SIDI) engine are satisfied and enables an engine prime mode when the predetermined operating conditions are satisfied. The fuel control module controls a fuel injector to deliver a prime pulse to a cylinder of the SIDI engine when the engine prime mode is enabled. The fuel injector delivers the prime pulse by opening for a pulse width to inject fuel directly into the cylinder when the SIDI engine is stopped.

International Classification:

F02D 41/26
US Classification:

701113
Abstract:

An engine control system includes a fuel system including a first fuel pump in fluid communication with a fuel tank and a second fuel pump in fluid communication with the first fuel pump. A pump control module selectively turns on the first fuel pump when a door opens before an engine is started, the engine is not cranking and a rail pressure of the first fuel pump is less than a predetermined rail pressure.
