Abstract

See full text

A vehicle system includes an engine defining a plurality of cylinders and configured to combust a fuel. A method of increasing efficiency of an engine includes controlling an amount of fuel being injected into the plurality of cylinders of the engine via a respective fuel injector. An exhaust gas recirculation (EGR) system is in selective fluid communication with a second subset of the plurality of cylinders and the air intake system to route the second exhaust product from the second subset of the plurality of cylinders to an air intake system. A valve is coupled to the EGR system and the exhaust system. A first sensor is disposed between the valve and the air intake system, and measures an amount of reformate in the second exhaust product when the valve is in a second position.
