Electrical Engineering capstone Project

“Wood Fuel Engine Control Unit (ECU)”
Graham Van Goffrier and Berkay Payal, advised by Stephen Abbadessa (MEE)

Abstract:  An engine controller unit for phase-adjustable ignition timing of a wood-fuel-powered engine was designed, implemented, and tested. This controller was designed to increase the fuel efficiency of the engine by allowing for more precise control of the fuel-combustion cycle. The engine controller met all the specifications outlined in the project contract. Ignition timing phase was controlled with precision of 1° with maximum 50° advance from center. The engine was operated with aforementioned precision up to 75 Hz timing signal frequency and with output period within 1° of timing signal period. Furthermore, a thermocouple amplifier was designed to measure the temperature of the engine exhaust. The temperature circuit was able to measure temperatures in the range of 600°F to 1900°F within 25°F precision. An LCD operated by the controller was configured to display the operating phase and speed of the engine in real time, along with the exhaust temperature.
