Abstract

This project aims to study advanced combustion systems using diesel and natural gas blends for Internal Combustion Engine applications. The main goal is to investigate, focusing on the fundamental physical processes, the combustion of natural gas blends ignited by pilot diesel sprays. The sub-optimal fuel-air mixture results in emissions of unburned hydrocarbon (UHC). In particular, one of the most severe UHC emission is the release of the unburned greenhouse gas methane (CH4) into the atmosphere (methane slip). To better understand the origin of methane slip, in-depth knowledge of the turbulent mixture formation process is required [1][2].The engine with optical access with high pressure levels (up to 100bar ) is unique in Brazil. This equipment will provide the state of the art facility for the execution of research and investigations on the topic internal combustion engines. The flexibility of the equipment allows the investigation of various aspects of the use of conventional and alternative fuels. Researchers from Brazil, particularly from the State of São Paulo, will have access to the equipment through a scheduling agenda in a site with its own internet address, thus optimizing their use and consequently the funds invested by FAPESP.
