French Expertise in Diesel Technologies at SAE Commercial Vehicle Show this October
Kimberly Elsham :
For the first time, French companies specializing in diesel technologies will be exhibiting at a collective booth at the SAE Commercial Vehicle Engineering Congress & Exhibition in Rosemont, Ill. From Oct. 30 to Nov. 1 at booth 706, the Diesel France pavilion, organized by the French Economic Mission, will be a one-stop-shop for learning about the latest in diesel technologies for commercial vehicles. With the one of the largest diesel-engine productions in the world and more than 70% of passenger vehicles sold in the country being diesel-powered, a large market devoted to research and development of diesel technologies exists. The diesel experience and expertise fine-tuned for passenger engines is shared with commercial vehicle powertrain platforms as well. The 13 companies comprising the Diesel France pavilion will present a variety of technologies used on a diesel-powered vehicle, from engine parts to test benches, and from fluid transfer systems to exhaust treatment.
Aquarese has developed high-pressure processes for diesel injection systems (common rails, tubes, and injectors). Its design department integrates those processes in automated lines including machines for deburring, flushing, cleaning, and the “autofrettage” technique. The autofrettage technique significantly increases the fatigue behavior of hollow mechanical parts. It is used on thick-walled metal tubes or pipes such as common rails, pipes, and injectors for diesel-injection systems, to improve the durability of the part by creating a compressive residual stress at the bore. For a few seconds, the part is subjected to a pressure 43,000 to 116,000 psi (3,000 to 8,000 bars) generating a plastic distortion of the inside wall, which is similar to preloading strain-hardening. The result is that after the pressure is removed, the elastic recovery of the outer wall puts the inner wall into compression, providing a residual compressive stress.
Céramiques Techniques et Industrielles (CTI) has developed a high-quality patented Monolith Diesel Particulate Filter (DPF) in silicon carbide able to reduce the particulate matter emission from diesel exhaust and to meet the upcoming Euro 5 standard for heavy-duty vehicles and passenger cars. The flexibility in the manufacturing process allows high-performance filters available with a large range of porosity and pore-size distributions that the company is able to offer at a lower cost than that of its competitors. CTI’s DPF can be easily packed into different exhaust system designs, such as a single filter for light-duty vehicles or multiple filters for medium- and heavy-duty vehicles such as long-bed trucks, urban buses, and delivery or waste vehicles. Thousands of diesel engines in buses and small trucks have been using the CTI DPF for the last three years. The company produces nearly 9,000 cubic feet of DPF each year.
