Abstract
Performance and emissions comparisons have been made between helical and directed ports for a range of injection rates. The tests were carried out on a single-cylinder research engine of 120 mm bore with a cylinder head capable of accepting interchangeable inlet ports. An important feature of the work was optimisation of the nozzle specification for each combination of port and pumping rate. The aim was to assess the advantages of each port design under various conditions. The results showed that similar performance and emissions could be achieved by both helical and directed ports.
