Downsizing has become an automotive market trend when it comes to internal combustion engines. Reducing the number of cylinders and decreasing engine displacement, without compromising torque and engine performance, is critical to meet the ever growing demand for fuel efficient vehicles with lower emissions. Turbochargers play a decisive role with regards to engine downsizing, both for diesel and gasoline engines.

Market experts forecast that by 2016, the number of turbocharged two- and three-cylinder engines will double. Moreover, the number of highly efficient four-cylinder engines will increase by 20 percent, to more than 20 million units. While turbochargers are a widespread feature in cars with diesel engines, as well as in light and heavy commercial vehicles, there is still great potential for growth with gasoline engines. However, forecasts are clear: in the near future, every carmaker will offer turbocharged gasoline engines and demand for turbochargers is expected to grow more than 130 percent. This translates into roughly 12 million units per year.

In view of this dynamic market environment, Bosch Mahle Turbo Systems is in a very solid and strategic position. Although this young company has yet to launch its products, contracts for delivery with six major carmakers have already been signed. In fact, the company expects to deliver more than one million turbochargers per year. “The trust that our customers have placed in our company underlines our efforts to offer a high quality product that meets high expectations; and all of this at a competitive price,” notes Dr. Andreas Pang, managing director (production, purchasing, and quality management) of Bosch Mahle Turbo Systems.

The product portfolio comprises of turbochargers, with wastegates, for gasoline engines producing power ranging between 45kW to 220kW. For diesel engines the portfolio offers products with a performance range, between 30 and 530 kW, and can also include variable turbine geometry (VTG). These are used in a variety of vehicles ranging from passenger cars to heavy-duty commercial vehicles. The product portfolio also includes very compact charging systems in which the exhaust manifold is integrated into the turbine housing. “Our product is the result of a continually iterative process and quality oriented development phase. This begins at the design stage, continues through to the first prototypes, and ends with a high quality turbocharger that is ready for series production", states Dr. Martin Knopf, managing director for development, sales, and finance. “As a result of our focused approach, we are able to quickly meet individual customers' needs without compromising on quality or perfomance.”

Bosch Mahle Turbo Systems has set a high standard when it comes to efficiency, durability, and acoustics. This applies to all its products, regardless of whether they are applied to a two-cylinder gasoline engine, an efficient high performing four-cylinder diesel, a high-capacity diesel commercial vehicle or even as part of an extreme downsizing concept.

Turbochargers, for downsized engines, require immediate dynamic behavior when load conditions rapidly change. This requires the lowest possible rotational inertia of the rotor unit; which comprises of the main shaft, compressor wheel, and exhaust turbine. Bosch Mahle Turbo Systems has achieved this reduction by decreasing weight and friction. This attention to detail has had a beneficial effect on transient response and fuel consumption. These characteristics are determined by the overall turbocharger design and optimum flow efficiencies; which are designed with internally developed simulation tools and models. As a result, Bosch Mahle Turbo Systems turbochargers are highly efficient and robust.

Thanks to a new and very precise rotor manufacturing process, coupled with a low- friction bearing system, the turbochargers have set the benchmark with regards to durability and acoustics. The solid billet aluminum compressor wheels, which are completely machined using a high precision manufacturing process, also play an important role in these aspects of performance. As a result, the technically improved production quality provides constant air volume, between the compressor blades, which in turn dampens the sound of pressure pulsations.

Both the manufacturing sites, in Blaichach; Germany and St. Michael; Austria, are equipped with state-of-the-art production facilities that are part of a major investment of several million euros. Pre-series production has already begun at these sites and turbocharger manufacturing is prepared to quickly ramp into series production at the beginning of 2012.

There are more than 200 associates currently working at Bosch Mahle Turbo Systems. By 2013, there will more than 300 employees. “We are looking for strong growth and are actively hiring many technical specialists. We offer fabulous opportunities for talented individuals with creative minds,” – Dr. Martin Kopf.

Bosch Mahle Turbo Systems is a joint venture between Bosch und MAHLE. It combines comprehensive systems expertise for internal combustion engines with extensive know-how in the development and series production of motor parts and components. The company develops turbochargers for motors in passenger cars and commercial vehicles. The joint venture was initiated in 2008 and currently has more than 200 associates.
