During the second reporting period, the project team focused on identifying promising technologies that can then be used to monitor and control emissions from E&P engines. These technologies include control and monitoring technologies and in most cases can be used to monitor engine performance as well as control and monitor engine emissions. The project team also identified three potential sources to receive a Cooper Ajax engine that is approximately 100 bhp. The goal is to have this engine delivered to the project team by the end of the calendar year 2003. This will then allow the team to prepare the engine for testing at Ricardo in early 2004.

During the third reporting period, the project team continued to focus on identify promising technologies that can then be used to monitor and control emissions and E&P engines. These technologies include control and monitoring technologies and in most cases can be used to monitor engine performance as well as control and monitor engine emission. The engine frequency distribution used in the E&P industry was significantly enhanced, and now shows the most prevalent engines used in the industry. The most prevalent four stroke cycle engines are the Waukesha and Caterpillar engines, while the most prevalent two-stroke cycle engine is the Ajax.
