Abstract: A method of controlling fuel injection in an engine of a vehicle having an anti-lock braking system comprises under conditions of degraded operation of an anti-lock braking system, restricting deactivation of the fuel injection during deceleration vehicle operating conditions. According to another aspect, the method comprises under conditions where the anti-lock braking system is functioning, disabling fuel injection during at least some deceleration operations; and under conditions of degraded operation of the anti-lock braking system, restricting deactivation of the fuel injection during deceleration vehicle operating conditions. By considering the functioning of an ABS, it is possible to deactivate fuel injection during some deceleration operations during one condition to realize fuel economy gains and disable the deactivation of fuel injection at another condition to reduce engine stalls. Thus, the deceleration fuel shut off strategy may be used aggressively for improved fuel economy.

Abstract: A method for controlling stopping and starting of an engine having a variable event valvetrain is described. According to the method engine valves may be used to reduce engine evaporative emissions as well as engine starting emissions. Since the engine configuration shown has electrically actuated intake and exhaust valves it is possible to reconfigure the engine operating sequence during a start. For example, the pistons for cylinders two and three are in the same position at the same time. This allows either cylinder to be set to an intake stroke during a subsequent engine restart when the piston is traveling away from the cylinder head while the companion cylinder is set to the expansion or power stroke. Thus, the cylinder having the first intake stroke could be configured to provide a first combustion event during an engine restart.
