Turbochargers Increasing Acceleration and Contributing to Environmental Performance

Around the world, fuel-effi ciency regulations on automobiles are growing stricter. While demand for vehicles is rising, particularly in emerging markets, on the other hand automakers face the urgent task of meeting stiffer requirements. Under these conditions, expectations are growing for turbochargers, which boost the fuel effi ciency of gasoline- and diesel-powered vehicles. MHI is contributing to better fuel effi ciency through its efforts to develop high-performance turbochargers and promote them on a global basis.

  • Concern about environmental pollution as the number of vehicles in the world grows
  • Increasingly stringent exhaust emissions going into place throughout the world

Global automobile production continues to rise. During the past decade, the number of automobiles manufactured each year has risen approximately 40%, to 90 million. Underpinning this growth are emerging countries, which are heightening in importance as production bases as well as consumer markets. In the past, the automotive industry hinged on advanced countries, but this focus is expected to continue shifting toward emerging markets. World automobile production is predicted to expand to around 100 million units per year by 2018. Meanwhile, emerging countries such as China and India are facing air pollution from automobile exhaust. As a result, countries around the world are adopting ever-stricter fuel-effi ciency requirements, such as the Corporate Average Fuel Economy (CAFE) regulations in the United States. It is growing increasingly diffi cult for vehicles to get to market unless they deliver superior fuel effi - ciency. Accordingly, boosting fuel effi ciency is of pressing importance for automakers the world over.

  • Core technologies for the development of high-performance turbochargers
  • Global production system in place

Automakers are developing hybrid and electric cars in the interest of enhancing fuel effi ciency. At the same time, market demand for turbocharged engines, especially gasoline engines, is increasing rapidly. Installing a turbocharger simultaneously reduces exhaust volumes and boosts performance compared with other engines in the same class, so smaller engines can be used. This combination contributes to substantially higher fuel effi ciency. Turbochargers also curtail the amount of harmful substances contained in emissions, allowing gasoline and diesel vehicles to pass stricter fuel-effi ciency regulations. However, developing high-performance turbochargers is no easy feat, as it requires the application of technologies capable of high-speed turbine rotation at elevated temperatures. MHI has cultivated the core technologies needed in automobile turbochargers though its work in aircraft engines and gas turbines. The Company has also earned a strong reputation among customers for the low failure rate of its products. MHI is building a global production system to meet the steady ongoing increases expected for turbocharger demand.

  • Augment turbocharger production capacity
  • Develop next-generation turbochargers

Help to achieve a low-carbon society through growing global uptake of turbochargers

MHI is investing aggressively to build a worldwide structure capable of producing 10 million turbochargers per year. By investing a total of ¥15.0 billion in its overseas production bases, including a key component manufacturing facility in Thailand, by 2016 MHI expects to have in place a structure capable of manufacturing 10 million units per year. At the same time, to enhance cost competitiveness the Company aims to achieve a flexible production structure with four focal points—Japan, the United States, Europe, and Asia. Forthcoming innovations include a new-concept turbocharger that achieves the world’s highest level of efficiency and an electrically driven two-stage supercharging system (turbocharger) that will allow further downsizing of gasoline engines. MHI is cultivating the market for such products. In addition, we are creating a locally responsive engine development support structure through which we will be able to respond to diverse market needs from nearby bases precisely and with short delivery schedules. Going forward, we will continue to strengthen these measures, making additional investments if necessary, to achieve our goal of garnering a leading share of the world market for automobile turbochargers. MHI aims to contribute to a low-carbon society by encouraging the spread of turbochargers, which can play a key role in improving fuel performance.

VOICEWe had been working to attract an environmentally conscious company, so MHI’s establishment of a turbocharger plant in Franklin was a welcome occurrence.

The city of Franklin and Johnson County, Indiana, are delighted to have an MHI turbocharger production plant in our community. We strive to attract environmentally friendly companies and are extremely pleased about MHI’s new product technology that will manufacture turbochargers capable of reducing CO2 emissions and fuel consumption in the environment.

We have had a long-standing relationship with the MHI Group for automotive parts business and look forward to building such a relationship for turbocharger.

Congratulations, and welcome to your new Franklin home!
