Guidance and Control System for Under Actuated Marine Surface Vessels

WSU researchers have developed a guidance system that yields a faster convergence rate of the ship to its desired trajectory than existing systems. The new algorithm varies the radius in the guidance algorithm exponentially as opposed to linear variations in existing schemes. This was done to prevent the system from over-reacting for small cross track...

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...

Fuel Injector to Work as an Ionization Sensor and as an Injection Signal Detector in Electronically Controlled Fuel Injection Systems in Diesel and Direct Injection Gasoline Engines

Wayne State researchers have created an invention which uses one element in the engine, the fuel injector, to perform four tasks, injecting fuel, acting as an injection pulse detector, operating as a fuel injector malfunction detector and working as an ion sensor without modifying the fuel injector. Internal combustion engine control has become more...
