Bosch Sees Nearly 18% Increase in Common-Rail Sales Worldwide in 2007

The Bosch Group anticipates increasing sales of its common-rail diesel direct injection technology by nearly 18% to more than eight million systems in 2007, up from 6.8 million last year. Bosch alone has equipped more than 33 million passenger-car and commercial-vehicle engines with this technology since 1997.

Ten years ago, Bosch was the first company to put a common-rail system for passenger cars on the market. The first vehicles to feature the technology were the Alfa Romeo 156 JTD and the Mercedes-Benz 220 CDI.

In conjunction with turbocharging, the injection system has helped the diesel engine achieve a market breakthrough to approximately 50% of the new car market in western Europe. Ten years ago, diesel’s share was only 22%. The diesel engine’s main selling points are its reduced fuel consumption and lower CO2 emissions, combined with a much cleaner emissions profile than before.

Since the early 1990s, carbon monoxide, nitrogen oxide, and hydrocarbon emissions from new diesels have been reduced by 95% and more.

Our common-rail technology will play a major role in meeting the future Euro 5, Euro 6, and US07 Bin5 exhaust emission standards. As a result, the combination of common-rail technology and exhaust-gas treatment is securing the future of the diesel engine.

—Dr. Ulrich Dohle, president of the Bosch Diesel Systems division

In 2006, Belgium had the highest percentage of diesel engines with a market share of 74%, followed by France (71%), Spain (68%), Portugal (65%), Austria (62%) and Italy (59%). In Germany, 44% of all new passenger cars had a diesel engine.

Bosch expects the market share of diesel-powered light-duty vehicles in the US to increase from its current level of approximately 6% to 15% in 2015. Bosch also expects rapid growth in Asia.

This year, Bosch plans to sell about 100,000 common-rail systems in both India and China. By 2013, it is likely that there will be some 1.3 million such systems in each of these countries. At present, just one-fifth of the company’s total production of high-pressure injection systems is for the markets in Asia and the Americas, but by 2015 this figure will be nearly 50%.

Bosch currently supplies common-rail systems with injection pressures of 1,350, 1,600, and 1,800 bar, using both solenoid-valve and piezo-valve technology.  The next step—2,000-bar systems—goes into series production before the end of the year.

At the same time, Bosch is developing more cost-effective common-rail systems with an injection pressure of 1,100 to 1,450 bar for emerging markets such as India or China. They are primarily intended for the low-price vehicle segment, and will be launched at the end of 2007. For the middle market segment, Bosch is developing new systems in order to gradually reduce costs and fuel consumption.

There are developments in DME in China:
We see great potential for DME as a clean alternative fuel . The present diesel oil is a major source of air pollution from diesel engine of trucks and busses in large city like Tokyo. The potential market of diesel oil substitute is larger than LPG. DME is one of ideal fuel for diesel engine. DME vehicles were demonstratively manufactured in Japan, China and Korea and their driving test already started. Practical durability fleet test of a DME truck is under going in Japan.

We are pleased to organise a conference on China taking the lead in the DME market in production from coal and Japan and Korea activities.

If you would like to know more on COAL to Syngas to DME developments, join us at upcoming North Asia DME / Methanol conference in Beijing, 27-28 June 2007, St Regis Hotel. The conference covers key areas which include:

DME productivity can be much higher especially if
country energy policies makes an effort comparable to
that invested in increasing supply.
National Development Reform Commission NDRC
Ministry of Energy for Mongolia

Production of DME/ Methanol through biomass
gasification could potentially be commercialized
Shandong University completed Pilot plant in Jinan and
will be sharing their experience.

Advances in conversion technologies are readily
available and offer exciting potential of DME as a
chemical feedstock
By: Kogas, Lurgi and Haldor Topsoe

Available project finance supports the investments
that DME/ Methanol can play a large energy supply role
