Abstract

The increasingly stringent requirement to reduce fuel consumption and emissions is pushing carmakers to investigate new and more challenging alternatives. In this rushing scenario, the Direct Injection of Compressed Natural Gas has emerged as a high potential strategy to improve SI engine performance. Since the direct injection of natural gas is an emerging technology, the research of the optimal setup, looking at the injection parameters and at the design of the combustion chamber, is still a relevant issue. This thesis has the goal of realizing and validating a model of a DI CNG injector. After this first step, the mentioned model is used to evaluate the effect that some of the most important parameters have on the mixture formation.
