Analysis of Telematics Data of Combine Harvesters and Evaluation of Potential to Reduce Environmental Pollution

The combine harvester (CH) is one of the most important machines with powerful engine used in agricultural sector. It consumes significant amounts diesel fuel and harms ambient air by releasing emissions. This study examines telematics data CHs (models axial threshing apparatus) collected between 2017 2020. time spent various operating modes CH, consumption, negative impact on (expressed global warming potential–(GWP)) were calculated. Field tests using same CH model also performed to confirm data’s values. Possibilities minimize consumption pollution selecting correct use technological operations are evaluated. Telematics analysis results showed that spends ~18% ~13% idle transport modes, respectively. was found ~12% consumed outside direct harvesting mode, amounting 4.7 t year?1 GWP per machine. Dual telematics/field studies optimal could reduce amount pollutants released into environment terms 1.3 for have shown ton wheat harvest highly depended driving speed during harvesting. optimum determined as 4 km h?1, grain straw feed rate 24 kg s?1.
