摘要: A reserve torque system comprises a first module and a reserve torque module. The first module generates a first signal a predetermined period before an equivalence ratio (EQR) of an air/fuel mixture supplied to an engine is transitioned from a non-lean EQR to a lean EQR. The reserve torque module creates a reserve torque between when the first signal is generated and when the EQR is transitioned to the lean EQR.
