Abstract
Field tests were performed in order to find diesel engine load parameters for typical farm tasks. Computer programs for evaluating farm tractor load parameters and calculating the specific emissions for each load cycle were made. Typical load parameters are presented. Because of quite low load factor, the specific emissions are quite high. Fuel consumption can be lowered 10% by changing the engine operating point to a higher level. If the engine is operated near the optimal fuel consumption, emissions except NOx were on low level. Hydraulically operated machines have highly transient load, which influence mostly CO, HC, and PM emissions.
