Grid Computing is a relatively new concept that provides a high performance metacomputing platform consisting of multiple computers connected using high-speed networks. The metaphor computational grid is based on the electrical power grid, which provides ubiquitous electrical power. In the same way, a computational grid has the potential of providing ubiquitous computing power. Connection of many computers at appropriate speeds has become more feasible with the recent deployment of high-speed second-generation optical Internet infrastructures, such as Internet2 and CA-Net 3 in North America and DANTE/ GÉANT in Europe. These networks can interconnect computing nodes in a grid at up to gigabit speeds. This paper is an exploration of the potential of using Grid Computing services to serve the Automotive Design industry.

Cold idle operation of a modern design light duty diesel engine and the effect of multiple pilot injections on stability were investigated. The investigation was initially carried out experimentally at 1000rpm and at −20°C. Benefits of mixture preparation were initially explored by a heat release analysis. Kiva 3v was then used to model the effect of multiple pilots on in-cylinder mixture distribution. A 60° sector of mesh was used taking advantage of rotational symmetry. The combustion system and injector arrangements mimic the HPCR diesel engine used in the experimental investigation. The CFD analysis covers evolutions from intake valve closing to start of combustion. The number of injections was varied from 1 to 4, but the total fuel injected was kept constant at 17mm3/stroke. Start of main injection timing was fixed at 7.5°BTDC.
