Analysis of patent deposits and PROCONVE MAR – I in the development sector of agricultural machinery engines 2018-36-0271
Agriculture is directly associated with climate change issues and is a major source of Greenhouse Gas (GHG) emissions. Part of the emissions are the result of burning fossil fuels such as coal, natural gas and oil in internal combustion engines of agricultural machinery. In addition, because of negative impacts on air quality, human health and climate change, new strategies are being developed to reduce the impacts of GHG emissions. However, it is noted that there is a lack of information that instigates emissions of non-road equipment, such as emissions from agricultural machinery. Thus, in order to achieve climate policy objectives, new trends in agriculture are being adopted. They set emission standards for GHG reductions by agricultural engine engines. In Brazil, the Program for the Control of Air Pollution by Automotive Vehicles (PROCONVE) is responsible for establishing the legal regulations for admissible emissions for the different categories of motor vehicles. In order to control the emission limits of agricultural and road machinery, PROCONVE granted the MAR - I phase (Agricultural and Road Machinery), which came into force in 2015. Brazil, through the regulation of PROCONVE MAR - I, seeks to reduce GHG emissions, which among its guidelines are the improvement of the concepts of agricultural engine engines and their post - treatment technologies, resulting in improvements in the control of atmospheric emissions from exhaust gases. Thus, the article presents an analysis of the deposits in patent bases, through the Questel Orbit Platform, aiming at verifying who are the main manufacturers of the Brazilian market, what are the post-treatment systems for agricultural machinery engines and who are the countries which stand out for developing technologies linked to the reduction of the emission of pollutants. As a result, the main meta specifications structured in agricultural machines in countries with high emission standards include Selective Catalytic Reduction (SCR) for the control of NOx (Nitrogen Oxides), Exhaust Gas Recirculation (EGR) to enable cooling of the NOx formation and the Diesel Particulate Filters (DPF) in the control of PM (Particulate Material). In addition, the Electronic Fuel Injection System also allows a significant reduction in the emission of pollutant gases. As a consequence, research on these results can help to provide new conceptions of products that, besides being functional, have a legal adequacy, thus establishing a connection with PROCONVE MAR - I.
