Controlling diesel engine used in lean mode and rich catalyst regeneration mode, first derives fuel quantities used in each mode from running parameters

摘要

A first injected fuel quantity (QM) corresponding with weak running is derived, starting from the engine speed and desired torque. A second injected fuel quantity (QF) corresponding with rich running is derived from engine speed, desired torque and a lambda value. From these quantities (QM, QF), the quantity of fuel to be metered to the engine is determined. An Independent claim is included for corresponding equipment.
