Abstract
  • Commissioning of the single cylinder optical engine with VVA emulation and analysis effect of heavy external cooled EGR on combustion. As foreseen, the optical engine was then prepared in order to simulate the EH-VVA system performance. To this aim, the chosen solution concerned in a throttle valve in the exhaust duct able to reduce the exhaust flow rate so allowing the simulation of internal EGR. Before performing tests with internal EGR, preliminary tests were carried out on the optical single cylinder CR DI engine at low load and speed conditions by varying the external cooled EGR rate up to 36%. Three values of EGR rate were selected: 0%, 17% and 36%, as in the case of tests on Ruggerini engine. In these conditions the analysis of the combustion was done through the twocolour pyrometry technique. In-cylinder flame temperature maps and soot concentrations and distributions were obtained for the different test cases. (literal)
