Leading Japanese automakers expect to see an improved fuel economy to the tune of as much as 30% by end of this decade. To achieve this aim, newly formed Research Association of Automotive Internal Combustion Engines has devised a $20 million project (approx Rs 337.3 crores). The Japanese government will be contributing half this investment, while the eight auto majors will invest the rest of the amount to ensure that this endeavour sees the light of day.
Through this endeavour, the 8 Japanese automakers – Toyota, Honda, Mazda, Nissan, Subaru, Mitsubishi, Suzuki and Daihatsu expect to see a marked improvement in fuel economy by the year 2020, while there are also even more objectives in mind. These include improvement of thermal efficiency of internal combustion engines to 50% from a current level of 39%, while it stands at 42% in diesel engines. The focus will be on reducing NOX emissions and particulate matter while gas engines will also be targeted so as to ensure complete combustion cycles.
These member companies will work jointly on basic research on better internal combustion engine while sharing costs to meet stringent fuel economy guidelines. Diesel engine development will involve elimination of particulate matter and nitrogen oxide emission through use of filters and exhaust gas recirculation systems while gasoline engine research will involve more complete combustion cycles and better ignition to reduce knock.
