Seals help dieselpowered vehicles lower their emissions

reudenberg-NOK Sealing Technologies reports that its CASCO cassette-type seals are capable of addressing the dynamic conditions under which diesel-powered vehicles operate and help lower their emissions. Diesel engines play an essential role in the transportation of goods and services. But light commercial vehicles and heavy-duty trucks are constantly exposed to aggressive environmental conditions – temperature extremes, atmospheric pollutants, challenging terrain – that can shorten the life of standard engine components and cost commercial freight companies valuable resources in terms of downtime and repairs. Pair these challenges with industry trends towards more stringent emission regulations, more intensive use of fleets, more global platforms and an active push to reduce production costs and heavy-duty vehicle manufacturers find themselves juggling a variety of industry issues. Freudenberg says that it has developed these cassette-type seals to address these dynamic trucking conditions. It claims that the CASCO crankshaft seals not only deliver up to 70% energy savings over traditional crankshaft seals, but they also result in better fuel economy, longer service life and significantly lower emissions. ‘Freudenberg-NOK understands the unique system needs of truck and bus manufacturers, and has provided a portfolio of technology that addresses these needs. Amongst those components is the CASCO seal,’ explained Jeff Nelson, Senior Director, Automotive, Freudenberg-NOK. ‘This seal is being used by a variety of automotive and general industry companies to great success. It has been field tested under the most extreme conditions and consistently outperforms traditional sealing products and systems.’ Compared with conventional lip designs, used in other engine seals, the cassette-type seal generates lower friction because of the design of its axial sealing lip. This grooved lip produces a combined pump and centrifugal effect for
enhanced sealing performance. A “hovercraft” effect between the sealing lip and the working counter surface results in low wear. The seal’s power-loss level also remains unchanged when the crankshaft diameter is increased, whilst other crankshaft seal designs show increasing power loss behaviour, says the company. In addition, it is less sensitive to the negative effects of ageing oil, and power levels remain stable, providing beneficial effects throughout the entire service life of the seal. Carbon residuals are pumped away from the sealing lip area, preventing stacking and leakages. CASCO seals have passed a number of tests representing polluted environments: in used oil, containing high percentages of carbon deposits; under low-temperature conditions; and with high eccentricity and axial play in the engine crankshaft. The seals demonstrated superior performance under all of these difficult conditions, says Freudenberg. Given an average 62 000 miles per year for a light commercial vehicle and 124 000 miles per year for a heavy-duty truck, the energy savings generated in one year by each engine equipped with CASCO seals at the crankshaft (front and rear) has been calculated to be approximately 800 kWh and 1500 kWh, respectively. This total of 2300 kWh represents a saving of almost 60 gallons of diesel fuel annually. It has been estimated that each gallon of diesel fuel pollutes the atmosphere with 21.7 pounds of CO2. Taking into account the current volume supplied for the vehicles mentioned, CASCO seals will contribute to a reduction of about 50 000 tons of CO2 emissions annually, says the firm.

IN BRIEF Bal Seal appoints manager for its aerospace and defence sectors US-based Bal Seal Engineering Inc, which designs and produces custom sealing, connecting, conducting and EMI/RFI shielding components, has appointed James Mecredy as the global market manager for its aerospace, and military and defence sectors. In this role he will help industry OEMs and tier suppliers improve equipment uptime, reliability and precision. He will be based at the company’s headquarters in Foothill Ranch, California. David Fogel, Director, Business Development, Bal Seal, says Mecredy’s appointment underscores the company’s continued and deepening commitment to the aerospace and defence industry. The firm’s shielding and sealing products and technologies enable advanced military equipment and commercial aircraft to operate efficiently and effectively in increasingly complex environments. ElringKlinger’s revenue increases to over E1.5 billion Germany’s ElringKlinger Group – a manufacturer of parts for cars, such as cylinder-head and speciality gaskets – maintained its consistent trajectory of growth in the financial year just ended. Based on preliminary figures for 2015, group sales revenue grew by 13.7% in total to reach E1507.3 million, compared with E1325.8 million a year earlier.
