Autonomous Operation of Electronically Controlled Diesel Engines on a Multitude of Fuels Using Ion Current and Other Combustion Sensors

WSU researchers have developed a method to enable advanced diesel engines to operate properly on fuels of different chemical and physical properties. This technology will allow conventional diesel engines to precisely adjust the operating parameters to meet the production goals in fuel economy and emissions at a relatively low cost. With the increase...

In-Cylinder Cycle-by-Cycle NOx Measuring Technique in Spark Ignited Engines

Currently, there is no technique that determines the quantity of NOx present at the end of the combustion cycle in spark ignited engines. Existing technologies for measuring NOx in spark ignited engines are limited to slow response sensors placed in the engine exhaust. Wayne State University researchers have developed a novel technique to determine...

In-Cylinder Cycle-by-Cycle Soot Measuring Technique in Diesel Engines

Currently there is no device or technology to allow for onboard soot measurement in diesel engine vehicles. Wayne State University researchers have developed a technique which utilizes the ion current signal produced from an ion current sensor installed in the combustion chamber of each cylinder to determine the quantity of soot present in the cylinder...
