PRESSURE RISE DELAY CHARACTERISTICS OF A HIGH SPEED DI DIESEL ENGINE WITH HIGH PRESSURE INJECTION

Cylinder pressure, injection line pressure and needle lift signals were acquired over a wide range of operating conditions from a Ford York DI diesel engine and a single cylinder Hydra research diesel engine fitted with a pump-pipe-nozzle (PPN) system and a high pressure electronic unit injector (EUI) respectively. The signals were analysed for pressure rise delay (PRD). Ignition delay and PRD data was also obtained from a photographic build of the Hydra via laser illuminated high speed cine photography with a synchronised data acquisition. Illumination delays from visual analysis of the film records are compared with pressure rise delays. Pressure rise delay data is presented for both the injection systems. The influence of high pressure injection on ignition and pressure rise delays is examined. For the covering abstract see IRRD 873243.
