Computer Aided Data Acquisition and Control of an Internal Combustion Engine.
Abstract
Two microcomputers, a Digital Equipment Corporation VT-103 and an Octagon Systems Corporation SYS-1, were interfaced with a General Motors Model 1-53X3 single cylinder diesel engine to provide automated data acquisition and data reduction and engine control while running classroom experiments. Engine inlet and exhaust temperatures and pressures, RPM, torque and fuel flow along with additional engine parameters can be measured with the aid of a computer. Values for parameters such as specific fuel consumption, air-to-fuel ratio, and thermal efficiency can then be computed and both measured and computed values can be displayed and recorded. The Digital Equipment Corporation Computer is the parent computer and is used interactively for data acquisition and data reduction and for feedback control through the Octagon computer to which it is linked. The Octagon computer is used exclusively for control of the engine speed and load. (Author)
