ContiTech (booth 622) is exhibiting its second-generation SCR lines, fuel lines for upcoming heavy-duty engines, and high-performance charge-air lines at the Society of Automotive Engineers' (SAE) Commercial Vehicle Engineering Congress in Rosemont, Illinois, U.S.A., from October 5 to 6, 2010.
ContiTech Fluid Technology has received its first series production order for the new SCR lines in the U.S.A. Approximately 25,000 complete modules will be supplied each year to Cummins, the engine manufacturer, and used in the 6.7 liter Turbo Diesel engine for the Ram Chassis Cab from Chrysler. The new generation of lines already conforms to future Euro 6 and EPA 10 standards and features heated quick connectors with optimized contacting performance. The spiraled heating conductor as well as the bare crimped areas are coated directly for permanent protection from external influences like salt water and other media. The quick connectors are heated by recently developed plug-on heating sleeves. Two-part injection-molded plug connections allow numerous different options, making ContiTech well prepared for all orders to come. On the hoses, a durable EPDM cover combined with a butyl inner lining ensures better impermeability. ContiTech has, moreover, also developed a plastic version for SCR systems with retractive suction.
Selective catalytic reduction technology (SCR) is used in diesel engines to transform harmful nitrogen oxide into steam and nitrogen with the help of a urea solution. Heating of the SCR lines prevents the urea solution from freezing in low temperatures.
Extremely resilient fuel lines
ContiTech Fluid Technology has developed extremely resilient engine fuel lines specifically for heavy-duty truck engines with up to 16 liter displacement. With the new engines, it has been possible to significantly reduce both consumption and emissions. ContiTech's sustainable concept makes the system future-proof without restriction, not only with regard to the strict American EPA 10 exhaust emission standards, but also for potential future measures in reducing exhaust gas emissions.
Conventional fuel lines would be unable to cope with the requirements of these heavy-duty engines, Thanks to a new, extremely temperature-resistant rubber compound and special braiding, which can sustain the high operating pressures, the new lines can withstand pressures of up to 35 bar and operating temperatures of up to 130°C. "In the flame test, the lines proved themselves over a period of four hours - without any noticeable loss in performance," explains Herbert Kohn, sales and marketing manager for ContiTech Fluid Technology's truck segment. Stainless steel braiding is also available to further improve the heat dissipation.
Charge-air lines for all requirements
Automotive engineers demand that high-performance charge-air hoses and lines be up to withstanding ever higher pressure and temperature levels to realize their goal of marketing more compact, lighter-weight, yet higher-torqued and more fuel-efficient engines. ContiTech Fluid Technology develops and produces solutions that meet the most exacting performance requirements while coping with tricky installation situations. It has a wide range of elastomer products for these applications.
