Trial Objective: The purpose of this trial was to quantify the fuel saving and GHG outcomes of HPDI vehicles relative to conventional diesel vehicles in order to assess the performance of an LNG vehicle (HPDI technology) compared to a conventional diesel vehicle in terms of the impacts on GHG emissions and fuel costs.
Methodology The trial involved an in‐field assessment of an LNG linehaul vehicle (HPDI) relative to an equivalently configured diesel vehicle. The vehicles were B‐double dairy tankers running like routes between rural and metropolitan Victoria. The vehicles were operated simultaneously over a six‐week period. During the trial period, data loggers were used to collect drive cycle data relating to the operation of each vehicle to ensure validity of the fuel comparison. View further on Liquefied Natural Gas
