CNG is an alternative fuel with a better carbon to hydrogen ratio therefore permitting reduced<br />carbon dioxide emissions. It is injected in gaseous form for a much cleaner combustion almost cancelling some of<br />the emissions of the Diesel and it permits a much better energy security within Australia. The paper discusses the<br />best options currently available to convert Diesel engine platforms to CNG, with particular emphasis to the use of<br />these CNG engines within Australia where the refuelling network is scarce. This option is determined in the dual fuel<br />operation with a double injector design that couples a second CNG injector to the Diesel injector. This configuration<br />permits the operation Diesel only or Diesel pilot and CNG main depending on the availability of refuelling stations<br />where the vehicle operates. Results of engine performance simulations are performed for a straight six cylinder 13<br />litres truck engine with a novel power turbine connected to the crankshaft through a constant variable transmission<br />that may be by-passed when non helpful to increase the fuel economy of the vehicle or when damaging the<br />performances of the after treatment system.
