摘要： An exhaust gas recirculation system directs exhaust gasses from an exhaust manifold to an intake manifold of an internal combustion engine. The exhaust gasses travel from the exhaust manifold, first passing through a flow control valve and then through a measuring orifice before entering the intake manifold. Pressure upstream of the orifice is used, along with correction pressure downstream of the orifice, to measure and control exhaust gas flow. Further, manifold pressure is determined from downstream pressure and the used along with the measured exhaust gas flow to calculated a cylinder air charge amount.

摘要： A vehicle and engine control system controls engine torque to maintain positive torque at a transmission input to minimize the transmission gears from separating. By maintaining a positive engine torque, operation of the transmission in or through the zero torque, or lash, zone, is minimized. This minimizes poor vehicle driveability that would otherwise result from operation in the lash zone. The control systems uses closed loop control based on a desired and actual turbine speed ratio, or slip ratio, to provide positive torque to the transmission.

摘要： A system is described using a fuel quality sensor for controlling various aspects of engine operation. In particular, an acoustic wave sensor is utilized to measure viscosity and density of gasoline fuels. This measurement is utilized to predict engine combustion quality during an engine start.

摘要： Methods and systems are provided for controlling a vehicle system including an engine that is selectively deactivated during engine idle-stop conditions and selectively reactivated during engine restart conditions. One example method comprises, during an engine restart from an idle stop, performing a first combustion event in a cylinder with a piston at an engine crankshaft position that is after a crankshaft position at which said cylinder's exhaust valve opens, and before a crankshaft position at which the cylinder's intake valve closes, during a cycle of said cylinder. In this way, inaccuracies in cylinder aircharge estimation may be reduced, thereby also reducing air-fuel ratio errors and improving the quality and repeatability of engine restarts.

摘要： Various example approaches are described, one of which includes a method for adjusting relative delivery of liquid and gaseous fuel to a cylinder of the engine to effect rapid changes in cylinder air charge via changes in the displacement of fresh air by the gaseous fuel. In one particular approach, turbocharger lag is addressed by decreasing gaseous fuel injection while increasing liquid fuel injection to increase cylinder fresh air over and above any changes to fresh air via the throttle, wastegate, and/or turbocharger.
