“…It can be argued that the traditionally widespread transportation solution model (a self-propelled vehicle powered by petroleum-based fuels), which has lasted for a century, is depleted (Casotti & Goldenstein, 2008;Sierzchula, Bakker, Maat, & Van Wee, 2012). However, in recent years, and contrary to the future trends mentioned above, the profile of vehicles sold in Brazil has converged to larger and less efficient models, and among Brazilian cars, there is a trend of higher fuel consumption (Bastin, Szklo, & Rosa, 2010).…”

DYNAMIC CAPABILITIES IN ABSTRACTPurpose: The aim of this paper is to analyze the dynamic capabilities related to the generation of pollutant reduction techniques according with Teece's proposition. In order to do so, we developed a case study in a Brazilian automaker. Originality/gap/relevance/implications: This paper discusses empirically aspects of creation of dynamic capabilities and innovations from its foundations. The originality of the study resides in a clearer understanding inside an organization the conception of dynamic capabilities and innovations through time. Key methodological aspects: In this paper, an automaker was studied, focusing on interviewers' interpretations concerning on the creation of reduction of pollutants technologies. The data collected were qualitative and they were analyzed through the technique of content analysis. Summary of key results: As main results, we observed that Integration and development capabilities were found and they were characterized as dynamic capabilities in the sense that, they are all based in the automaker's adaptation to its external environment. The path dependence of the automaker was also observed, through all the innovations that were created during the automaker's history towards more efficient and less pollutant vehicles. Key considerations/conclusions: Summarizing, the automaker seeks to 'perceive' its dynamic capabilities from market's actions, since the organization has an historical path and also its R&D capabilities. So on the seizing phase of the Dynamic Capabilities, the organization seeks to 'create value' to its customers.

“…Este padrão utilizado na regulamentação incentiva a difusão de veículos de alta eficiência, incluindo propulsão elétrica, veículos menores (LIPSCY; SCHIPPER, 2013), uso de tecnologias com elevada eficiência e a perspectiva de inovações para o mundo. Visando a difusão de tecnologias automotivas de baixo carbono no mercado brasileiro (ICCT, 2015a), veículos com baixo consumo energético contarão como mais de um veículo para o cumprimento de meta corporativa, padrão também em uso nos demais mercados analisados neste estudo (ICCT, 2014b;ICCT, 2014c;ICCT, 2014a;ICCT, 2015c;ICCT, 2015d;ICCT, 2015a;EPA, 2012 A tecnologia downsizing (TAYLOR, 2008;ZAPATA;NIEUWENHUIS, 2010;POSADA;FAÇANHA, 2015;ROSA, 2010;PLOTKIN, 2009;SIMMONS et al, 2015;NRC, 2015) para a redução do tamanho dos motores caracteriza-se por um número menor de cilindros, com consequente redução do número de componentes móveis, favorecendo a redução do atrito (NRC, 2015) e peso, para a redução de emissões de GEE. Tal tecnologia está presente em 17,5% das versões de veículos do PBEV.…”

“…Tal tecnologia está presente em 17,5% das versões de veículos do PBEV. Em conjunto com esta mudança, a sobrealimentação do turbocompressor (TAYLOR, 2008;ZAPATA;NIEUWENHUIS, 2010;POSADA;FAÇANHA, 2015;ROSA, 2010;PLOTKIN, 2009;SIMMONS et al, 2015;NRC, 2015) permite extrair mais potência com um motor reduzido, ampliando a eficiência energética, e também contribuindo para a redução de peso. Os motores turbinados já equiparam veículos nacionais nas últimas duas décadas, e combinados com o downsizing permitem o uso de motores menores para redução no consumo de combustível ou ainda para aumentar o desempenho dos veículos, sem prejudicar as emissões.…”

“…Aliado ao downsizing com turbocompressor, o sistema de injeção direta (POSADA; FAÇANHA, 2015;ROSA, 2010;PLOTKIN, 2009;SIMMONS et al, 2015;DIJK;YARIME, 2010;TAYLOR, 2008;DIFIGLIO, 1997) envia o combustível diretamente à câmara de combustão, deixando de ter contato com as válvulas de admissão, que estão aquecidas, evitando assim a perda de eficiência no trajeto do combustível no coletor (POSADA; FAÇANHA, 2015), efeito que ocorre em um sistema de injeção de combustível indireta. Estas três tecnologias em conjunto equipam veículos nacionais, proporcionando ganhos de eficiência do motor com a redução de atrito e peso, e melhor aproveitamento do ciclo térmico, oferecendo desempenho superior, comparado aos motores aspirados com injeção eletrônica multiponto.…”

The search for alternative energy sources has been the subject of research to reduce greenhouse gases (GHG) emissions in the atmosphere. In recent decades, several countries, including Brazil, have taken actions to reduce toxic emissions from cars in favor of public health. To meet the new need to reduce the GHG emissions, the regulation has vital role in defining goals and standards that foster the technological improvement of automobiles. This study aims to analyze the diffusion process of environmental innovation incorporated into automotive propulsion technology, to mitigate greenhouse gases (GHG) emissions. To reach this goal, a research was carried out qualitative and descriptive, using as a basis the participating of Brazilian Vehicle Labeling Program. The experience of the major automotive markets is presented in order to place the Brazilian reality compared to these other regions.The result of this research shows the diffusion of technologies before restricted to more expensive models with higher performance, start to equip simpler models, aiming to increasing energy efficiency. It was also identified the introduction of technologies in the Brazilian market as direct fuel injection and engine with three cylinders. According the changes identified, legislation drive to technological balance process among the automakers, in order to favor environmental innovation diffusion, in the past restricted due to the cost, by way of technologies previously available in other markets start to equip Brazilian vehicles.

In this study, the corrosion behavior of AISI 304 fuel rail brazed joints in presence of ethanolic E85 fuel has been evaluated. The galvanic corrosion resulting from coupling steel and copper brazing alloys has been studied as it represents a potential risk for the functionality of the fuel rail and injectors. The corrosion can lead to nozzle clogging by the increase of level of solute metallic ions or rupture of the joint itself. Tests have been carried out both on specimens simulating the brazed joints and on real fuel rail component. Static immersion tests and static filling tests in standard gasoline, E85 and modified E85 fuels have been carried out. The latter have been prepared by adding aggressive reagent, such as acetic acid, sulfuric acid, and chlorides, to the E85 fuel. Tests have been carried out at room temperature and at 60 8C. Alternative brazing materials to copper alloys (nickel-and silver-based alloys) have also been tested, with the aim of comparing their corrosive resistance. From results here obtained, the nickel-based brazing alloys, which have been tested because of their intrinsic ability to passivate, have proved to be more resistant to corrosion than copper, but only during exposure to commercial E85 and at room temperature. Silver-based brazing alloys have shown poor resistance to corrosion and the tendency of soluted Ag ions to precipitate in presence of chloride ions.
