Kimberly Elsham :
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.

Electricfil Automotive specializes in sensors and actuators for diesel engine control systems. The company develops and supplies more than five million electromagnetic actuators every year for the new generation of common rail diesel injectors. To boost injector performance, Electricfil actuators optimize combustion in direct-injection engines by accurately controlling the quantity, flow rate, and timing of the injected fuel. They use robust, reliable, and efficient electromagnetic technology to provide a competitive solution with performance comparable to existing piezo technologies, but at a lower cost. The company also produces camshaft speed sensors for quick engine startup and crankshaft speed sensors for very accurate diesel-injection timing. More than 120 million Electricfil engine speed sensors are in use worldwide.

MTT MoteurTesT is a test bench facility, home to more than ten separate benches for heavy engines. Attuned with changing manufacturer requirements and increasingly stringent emissions regulations, the MTT facility is equipped with benches specifically designed for endurance tests and technical studies on engines, endurance tests for precise parts, and can accommodate fuel consumption and combustion analysis tests for both diesel and gasoline engines.

Machine manufacturer Silfax introduces its fully electric CNC tube-bender, the SE 9127, designed specifically for large-diameter tubes and pipes. The bender works on nine electrical axes and is capable of bending pipes up to 127 mm in diameter. The SE 9127 is accurate in linear positioning to 0.05 mm and 0.05 degrees during bending. The robust design is especially useful in bending difficult materials on tight bend radii and demanding part geometries such as those in truck exhaust systems. This machine is the first of its type to offer an automated tool changeover system that can reduce overall tooling cost and minimize setup and change over time. It is easily programmed using the industry standard XYZ, LRA, and YBC formats utilizing the available S-tube interface. The SE 9127 is controlled the by industry-proven Siemens 840C software to allow total flexibility in programming the most demanding tube- and pipe-bending applications.

SOGEFI Filter Division
Combining its famous chevron "zig-zag" pleating technology with innovative multi-layered, glass-free, and high-efficiency filter materials, the SOGEFI Filter Division develops and produces compact and efficient long-life diesel fuel filters for vehicle manufacturers and producers of high-pressure common rail fuel-injection system. These filters are designed according to strict demands and can include functions such as fuel-heating, temperature, plugging, and water sensors, pressure-regulation valves, priming pump, and even a fuel line low-pressure pump. To integrate all these functions into compact and price-competitive products, SOGEFI uses plastic-injection-molded housings and components, but can also produce metallic filters if specific crash-resistance is required. SOGEFI is able to supply diesel fuel filters fully compatible with bio-diesel and ULSD fuel blends available in the European and U.S. markets. The company has also developed a new filtration design to reach more than 95% water separation efficiency even with emulsified water in low IFT biodiesel fuels. The company is also active in the field of soot and blow-by-gas filtration.

Its high-performance makes it suitable to use in diesel engines for entire fleets and insures safer and longer drain intervals. Rubia oils show a significant increase in wear protection, piston deposit control, and oil consumption compared to API CI-4 oils. They also have exceptional anti-wear and anti-corrosion properties and outstanding soot-handling and oxidation controls. These oils can provide up to 40% life increase in post particulate filters.

Valeo Telma Electrical Systems
The Valeo/Telma, or VSC (Valeo Speed Controller), division designs and manufactures frictionless braking systems using electromagnetic technology that eliminates the drawbacks of auxiliary braking systems. Available as a new-vehicle mount or an aftermarket retrofit, these systems operate independently of engine and transmission, reducing wear and tear, and provide the highest commercially available levels of braking horsepower without putting loads on the engine, which is essential for current and future requirements when considering the new Environment Protection Agency emissions regulations. The brake systems also decrease stopping distances by nearly 30%, which help to meet current and future Federal Motor Vehicle Safety Standards braking requirements. Additionally, because the Telma system activates electronically within 120 milliseconds and prior to the vehicle’s friction brakes, the friction brakes stay cooler and life of the brake lining is extended exponentially. Telma has a wide range of applications designed for small and large commercial vehicles including buses, emergency vehicles, freight trucks, and waste vehicles.
