This paper describes work in progress involving the development of techniques for use in enhanced internalcombustion engine-management systems for application in motor vehicles. The aim is to improve the control of the engine by the application of intelligent-systems techniques, thus leading to reduced exhaust emissions and improved fuel economy. A neural-network technique is described for the ...

The equations of motion for the major components in an internal combustion engine are developed herein using a recursive formulation. These components include the (rigid) engine block, pistons, connecting rods, (flexible) crankshaft, balance shafts, main bearings, and engine mounts. Relative coordinates are employed that automatically satisfy all constraints and therefore lead to the minimum se...

Abstract. This project further investigates a model of a simplified internal combustion engine considered by Kranc in 1977. Using Euler’s method for ordinary differential equations, we modeled the interaction between the engine’s flywheel and thermodynamic power cycle. Approximating with sufficiently small time intervals (0.001 seconds over a period of 12 seconds) reproduced Kranc’s results wit...
