摘要: An engine control system includes an air control module, a spark control module, a torque control module, a transient detection module, and a launch torque module. The air control module controls a throttle valve of an engine based on a commanded predicted torque. The spark control module controls spark advance of the engine based on a commanded immediate torque. The torque control module increases the commanded predicted torque when a catalyst light-off (CLO) mode is active, and increases the commanded immediate torque when a driver actuates an accelerator input. The transient detection module generates a lean transient signal when an air per cylinder increase is detected while the CLO mode is active. The launch torque module generates a torque offset signal based on the lean transient signal. The torque control module increases the commanded immediate torque based on the torque offset signal.

摘要: A system for a vehicle includes a change determination module, a sulfur determination module, and a final equivalence ratio (EQR) module. The change determination module estimates a change in an amount of sulfur within a catalyst of an exhaust system of the vehicle. The sulfur determination module estimates the amount of sulfur within the catalyst based on the change. The final EQR module selectively adjusts fueling of an engine based on the amount of sulfur.
