Submitted : Fall 2011 The basis of my final project is the design of a model compressionignition engine. The engine is initially under atmospheric temperature and pressure from which the cylinder undergoes compression followed by combustion where the temperature and pressure inside of the engine drastically increases due to the combustion of the airfuel mixture. The cylinder of the engine thus returns to the maximum volume, which is the variable we are trying to solve for. The net work done by the cylinders throughout the cycle can be found by: Work_{total}= Work_{out}Work_{in}. This equation is the basis of my observations where I use other formulas such as PV=nRT and PV^{m}=C to manipulate each of them in order to set them all equal to the work formula where the integration of PdV must occur in order to set it equal to our work formula, from which we are able solve our final equation.
