A second and deeper investigation of methods for fuel consumption measurement on non road mobile machinery have been performed. In this investigation mainly two activities have been conducted; interviews regarding tractor fuel consumption measurement methods and simulations regarding fuel consumption for wheel loaders. In the case of methodology for fuel consumption measurements for tractors, the German Agricultural Society approach is considered to be the best method available and has to some extent become an unofficial industrial standard for testing tractor fuel consumption. There is however a caveat: no conclusions can be drawn yet as to how much variations in ambient conditions effect the results. This issue must be clarified before the methodology can be considered for certification purposes. The simulation study of a wheel loader shows that total cycle distance and vehicle acceleration/deceleration has the highest impact on the cycle fuel consumption. Sand pit resistance, or how hard the driver pushes into the pit also have an impact on the cycle fuel consumption. The efficiency of the hydraulics, the rolling resistance of the wheel loader and how high the bucket load has to be lifted have low impact on the cycle fuel consumption. Using a constant bucket load vs. actually loading and dumping the load has a low impact on fuel consumption suggesting that, if necessary, a fixed bucket load may be used (as described in the JCMAS H022 method).
