Emissions

Despite the growing interest in real operating emissions measurement and analysis of modern diesel and rapeseed oil powered tractors have been little studied. Here under real operating and ambient conditions, the emissions vary compared to the measurements on the test bench. Using a portable emissions measurement system (PEMS), TFZ has measured the emissions of a Fendt Vario 724 S4 with a Euro IV engine running on rapeseed oil fuel in accordance with DIN 51605 during ploughing in the field and on the tractor test stand.

Motivation

Exhaust gas emission limits from non-road mobile machinery (NRMM) such as tractors, excavators or loaders have been increasingly tightened in recent years. Type approvals for NRMM are currently carried out on the engine test bench according to Directive 97/68/EC. For research studies, emission measurements on the entire tractor system (without removing engines) with an eddy current brake connected to the PTO have also proven effective [1, 2, 3, 4]....
