Euro 6 made simple Bosch explains: What changes does Euro 6 entail for drivers? From car prices to emissions stickers


What is Euro 6?
Euro 6 is a European Union regulation that sets emission standards for vehicles. “Euro 6 will make diesel cars as clean as gasoline cars,” says Dr. Rolf Bulander, the member of the board of management of Robert Bosch GmbH responsible for powertrain technology. The main thrust of the new regulation is to set lower limits for vehicle emissions of particulates and nitrogen oxides. As of September 1, 2014, diesel vehicles may emit no more than 80 mg of nitrogen oxides per kilometer (gasoline vehicles: 60 mg per kilometer). This replaces the previous limit of 180 mg per kilometer. Starting January 1, 2015, all new vehicles sold must meet the Euro 6 limits.

What is the point of European emissions legislation?
Since the Euro 1 regulation was introduced in 1993, emissions from road traffic have been drastically reduced. Advanced automotive technology – as provided by Bosch – reduces emissions of substances such as CO2, nitrogen oxides, and particulates. Technical advances in powertrains are also having an effect: since 1990, particulate emissions from diesel engines have been reduced by around 99 percent, while modern diesels emit some 98 percent less nitrogen oxide than comparable vehicles from the early 1990s. As electrification of the powertrain continues to progress, emissions will fall even further.

Will cars now be more expensive?
Prices for models that comply with Euro 6 are generally in the same range as prices for comparable models that meet Euro 5. Sometimes Euro 6 models come with additional features – a different transmission, say, or different tires – that push up the price. Take away the additional cost of these extras, and there is currently no appreciable increase in the price of Euro 6 models.

How does Euro 6 change the technology of diesel vehicles?
Diesel vehicles need a perfectly tuned exhaust-treatment system in order to meet the lower limits set out in Euro 6. For vehicles weighing up to around 1,700 kilograms, a low-cost NOx storage catalytic converter is sufficient. “In heavy vehicles, only an SCR catalytic converter with AdBlue will do,” says Dr. Markus Heyn, president of the Diesel Systems division at Robert Bosch GmbH. This system injects AdBlue, an odorless urea solution, which converts the nitrogen oxides into harmless water vapor and nitrogen. AdBlue is refilled at regular service intervals.

Will my old vehicle still get the same emissions sticker?
The allocation of emissions stickers in Germany is not affected by the switch to Euro 6. Anyone who currently receives a Euro 4 or Euro 5 emissions sticker allowing access to the city center will keep the sticker after Euro 6 comes into force on January 1, 2015.

What does Euro 6 change for drivers?
For anyone who already has a car, Euro 6 changes nothing in Germany. They can continue to use their vehicle as before. According to the latest information, vehicle taxes for Euro 5 diesel vehicles will not change in Germany. It will also still be possible to drive in low-emission zones. Buyers of new vehicles, however, should be aware of the switch to Euro 6 if they want to have a model equipped with cutting-edge technology.

Powerful, and perfect for limited installation space The new Bosch HEF109-L starter motor for commercial vehicles Extended power range for exceptionally large engines

  • Powerful solution for diesel engines of up to 28 liters displacement as well as for stationary gas-powered engines
  • Engineered for mileage of up to 800,000 kilometers or 14,000 operating hours in off-highway applications
  • Adaptable to stringent system requirements
Large-volume engines place great demands on starters. At the top end of the power range, Bosch has a new addition to its 24-volt starter motor portfolio: the HEF109-L “large” heavy-duty starter motor for commercial vehicles and off-highway applications. The powerful starter motor generates 18 percent more power than the tried and tested “M” (medium) type starter motor on which it is based, and thus delivers a maximum output of 9.2 kilowatts. This is enough to reliably start engines with up to 28 liters displacement. Ulrich Kirschner, the president of Bosch’s Starter Motors and Generators division, sums up the benefits as follows: “This new high-performance starter motor is an excellent choice for particularly large engines such as construction machinery. These engines were previously very difficult to start with single starter-motor configurations.” This powerful single-starter solution makes a more complex parallel-starter system unnecessary. The technology is designed to achieve a mileage of up to 800,000 kilometers in on-highway use or 14,000 operating hours in off-highway applications.

Compact, robust, and reliable
The design of the HEF109-L with its 6-pole excitation concept is especially compact, making it particularly suitable for applications where installation space in the engine compartment is limited. The high thermal robustness ensures reliable starting of large engines – even at very low ambient temperatures or in long-lasting starting sequences.

Due to the significantly greater service-life requirements associated with commercial vehicles, the engagement itself is designed as a two-stage process in order to limit the wear of the ring gear and pinion: In the first stage, the pinion shaft including the pinion is moved forward cautiously, engaged, and turned slightly. In the second stage, the main current is released and the actual starting sequence takes place.

A mechanical relay integrated in the starter makes a connection to the engine control unit (ECU) easier. Unlike starts by ignition switch, the ECU can automatically control the starting sequence, which keeps emissions low.

For extreme conditions
The HEF109-L can also be upgraded. One example is the special dust protection, available up to IP57 protection class. An additional feature is the isolation of terminal 31. This separate connection to the battery’s minus pole is a feature of special applications such as railroad vehicles or watercraft, where increased safety and protection requirements against moisture and water apply. For maximum flexibility in diverse installation conditions, the starter motor can also be supplied with all common flange geometries, including a rotatable flange.

Parallel starter-motor systems with increased power output
For applications utilizing even larger-displacement engines, Bosch offers parallel starting systems. By setting two or three starter motors of the 109-family in a parallel-system configuration, the output of each individual starter motor can be aggregated. The new HEF109-L also allows the total output of the parallel starter-motor systems to be increased significantly. With a maximum output of almost 28 kilowatts, diesel engines with displacements of up to 84 liters and gas powered engines with displacements of up to 168 liters can be started reliably under normal conditions. Engines of this size are very common in off-highway applications and watercraft. Stationary engines such as generator sets – also need to start quickly and reliably to stabilize the power supply net if there is a power cut. The HEF109-L is an ideal choice for these applications as well.

Customizing exhaust-gas treatment Bosch Emission Systems: market for clean truck and construction machinery powertrains booming

  • Manufacturing in Neunkirchen expanded
  • “Market for off-highway segment and commercial vehicles will double by 2020,” says Dr. Markus Heyn
  • Growth of diesel in the United States boosts business
Ambitious emissions standards are boosting business worldwide for Bosch Emission Systems GmbH & Co. KG (BESG). Regulations such as Tier 4 final emission limits and Euro 6 are driving demand for exhaust-gas treatment systems for trucks, diggers, and other mobile machinery. “When it comes to commercial vehicles, the global market for these systems will double by 2020,” predicts Dr. Markus Heyn, president of the Diesel Systems division at Bosch. To keep pace with this rapidly increasing demand, BESG is now bringing new production facilities online in Neunkirchen, in Germany’s Saarland. At 3,500 square meters, the existing production halls reached the limit of their capacity some time ago. Now, nearly 15,000 square meters are ready for use. “In our new plant, we can make sure our manufacturing and logistics processes are ideal and cost-effective from day one,” says Uwe Becker, technical plant manager in Neunkirchen.

This expansion of facilities in Germany is only one of the ways Bosch can benefit from the forecasted market upturn. In addition, Bosch engineers are constantly refining the product portfolio, which covers everything from integration to the manufacture of complete exhaust systems – for both on- and off-highway applications. What’s more, BESG in North America has also started equipping large passenger cars, such as SUVs, with complete exhaust-gas systems. One of the drivers of this is growth in the diesel market in North America, with models such as the Jeep Cherokee or Dodgeb Ram 1500 serving as landmark projects. Currently, 37 diesel models are available in the United States; by 2017, that number is expected to jump to 60.

Bosch’s innovative integrated systems lower emissions per driven kilometer for passenger cars, commercial vehicles, and construction machinery. BESG can individually configure all systems to customer wishes and integrate them into vehicles or machinery, including certification. In addition, Bosch Emission Systems specialists provide systems for stationary applications such as generators.

Bend, weld, and laser
Three state-of-the-art manufacturing technologies are at the heart of BESG’s production operations. First, a fully electronic machine bends pipes measuring 2.5 to 6 inches in diameter; thanks to special tools developed in house, even the tightest bending radii are possible. Second, the latest robotic welding technology ensures efficient synchronous welding of components. Third, Bosch Emission Systems can cut complex shapes in all three dimensions using a globally unique laser system.

The company
Bosch Emission Systems GmbH & Co. KG was founded in 2010 as a joint venture with two other partners. Since then, BESG has been developing, manufacturing, and integrating exhaust-gas treatment systems for construction machinery and commercial vehicles. Bosch assumed sole ownership of the company in October 2012. Altogether, BESG currently employs more than 200 associates at its Stuttgart, Cologne, and Neunkirchen locations. At the Kentwood plant in Michigan, Bosch Emission Systems USA (BESU) also manufactures products for the U.S. market. Bosch Emission Systems is a reliable partner to automakers and engine manufacturers worldwide. This applies in particular to turnkey projects, in which BESG is responsible for purchasing as well as defining and integrating components.
