With the increased concern for the affect that the use of internal combustion engines has on the environment, interest in engine technologies that can reduce the emissions has increased significantly. One such example that is being investigated by Michigan State University is the use of a Dual Mode Turbulent Jet Ignition (DM-TJI) to replace the use of a traditional spark plug. A DM-TJI engine can produce a more complete burn of the fuel while also allowing for use of leaner air–fuel mixes resulting in improved fuel economy. Controlling the intake of air into the pre-chamber of the DM-TJI engine is extremely important for it to run properly since controlling the intake of air allows for purging and management of the strength of the ignition jets. To achieve this, a valve that is capable of operating at the speeds necessary to allow for the proper amount of air to enter the prechamber, has been designed and is under final fabrication. The purpose of this thesis is a proof of concept experiment and analysis. Areas of improvement have been identified and once viable modifications have been recommended.
