The Internal Combustion Engine Test Stand consists of a 3.1-liter V-6 multi-port fuel-injected engine coupled to an air-cooled eddy-current dynamometer via a custom-built clutch system. A computer-based engine control system allows for the analysis and optimization of the operation of the engine. Measurements include engine torque, horsepower and speed, full calorimetry on the radiator (coolant temperature drop and flow rate), fuel consumption, and flow rate of air. Temperature sensors mounted on the engine itself are used to estimate heat losses due to thermal radiation and convection. A computerized data acquisition system records all measurements to floppy diskette for distribution to students. The Operator’s Console provides information such as oil and fuel pressures, the fuel level in the tank and exhaust hood vacuum readings. The test stand has been designed and assembled completely by Senior Design students and graduate students. We have an Excel spreadsheet to perform energy balance calculations.

The Internal Combustion Engine Test Stand located in Room 122 Russ Engineering Center.
