Embodiment Construction

[0014] To promote an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It should be understood, however, that no limitation of the scope of the invention is thereby intended and that any alterations and other modifications of the illustrated embodiments and the principles of the invention as illustrated therein are contemplated herein as would normally occur to one skilled in the art to which this invention pertains any other application.

[0015] In embodiments according to the present disclosure, engine systems having different architectures may be controlled through a common torque control technique. That is, a common torque control technique may be applied to the engine based on the quality of fuel and air supplied to the engine. Such engines include spark ignition (SI) engines and compression ignition (CI) engines, such as diesel engines. It...

Abstract

A system comprising an engine and a controller configured to determine an air mass flow command to provide a target air mass flow value to the engine that is based on a base air mass flow value adjusted for engine operating conditions, deviations in the actual torque from a target torque, and corrected for flow conditions.

Description

[0001] Cross References to Related Applications [0002] This application is related to and claims the benefit of priority from U.S. Provisional Patent Application Serial No. 61 / 898,591 filed November 1, 2013. This application is also related to International Application No. PCT / US2013 / 056302 filed on August 22, 2013, entitled "ENGINE CONTROL SYSTEMS AND METHODS". The contents of each of these applications are hereby incorporated by reference in their entirety into this disclosure for all purposes. technical field [0003] The technical field relates generally to engine control systems, and more particularly, to engine control systems for controlling engine cylinder mass air flow to compensate for torque losses. Background technique [0004] Spark ignition (SI) engines may control torque differently than compression ignition (CI) engines. Torque production in SI engines is primarily controlled through control of the air, since SI engines typically attempt to maintain a sto...
