Citroën unveiling Cactus AIRFLOW 2L concept at Paris: Hybrid Air powertrain and 2L/100 km

18 September 2014

Citroën will unveil its new C4 Cactus AIRFLOW 2L concept at the Paris Motor Show. With the C4 Cactus AIRFLOW 2L concept, Citroën is demonstrating fuel consumption of 2l/100 km (118 mpg US) through the use of optimized design with a 20% improvement in aerodynamics; lower rolling resistance (Tall&Narrow) tires; efforts to use lighter parts and thus reduce overall vehicle weight by 100 kg; and the implementation of Hybrid Air technology (earlier post), which cuts fuel consumption by 30%.

The C4 Cactus AIRFLOW 2L project was conducted as part of the “2l/100 km vehicle” program set up by the Plateforme de la Filière Automobile, an industry group. The objective was to deliver practical solutions to reduce the impact of vehicle running costs, on household expenditure and to reduce the eco-footprint of car travel.

MAHLE NanoNapier Steel piston ring helps reduce weight and improve quality

18 September 2014

MAHLE has developed a piston ring with new technology that offers engine manufacturers improvements in weight, quality and overall value. MAHLE’s new “second” piston ring uses chrome-silicon steel to replace cast iron traditionally used for the second of three rings found on gasoline-powered spark-ignition engines. MAHLE’s thinner, lighter-weight steel-wire design for the second ring is based on the company’s own NanoNapier Steel (NNS) technology for which a patent is pending.

Conventionally, there are two types of piston rings: compression and oil control. A piston assembly includes one or more compression rings that generate a seal between the outer surface of the piston and the wall of the cylinder to prevent high-pressure combustion gases and air from escaping the combustion chamber. Today’s engines have three piston rings: two compression rings: top (or first) and second and the oil control ring. The second ring is known as a Napier ring.

ArcelorMittal develops two steel solutions to reduce weight of pickups; exploring applications in PHEVs

18 September 2014

ArcelorMittal, the world’s largest steel and mining company, has created two sets of steel solutions to reduce the average weight of pick-ups, following on from the award-winning launch of its S-in motion catalogue for standard, C-segment cars. ArcelorMittal has refined and extended these innovations to help meet the specific challenges facing the North American light truck market.

The first set uses currently available advanced high strength steels and press-hardenable steel grades such as Usibor 1500 and Ductibor 500 and can reduce weight by up to 174 kg (384 lbs) or 23% of the combined weight of a pick-up’s cab, box, frame and closures, compared with a modern (2014) baseline vehicle.

BMW has introduced two variants of its new generation of 2.0-liter four-cylinder diesel engines in the 5 Series which boost the output of the new BMW 518d and new BMW 520d by another 5 kW apiece. Average fuel consumption drops to as little as 4.1 l/100 km (57.4 mpg US) (European cycle) and CO2 emissions to 109 g/km; this marks a reduction in consumption and CO2 emissions in the EU test cycle by as much as 0.4 liters per 100 kilometers / 10 grams per kilometer.

For example, the new BMW 520d Sedan—which now produces 140 kW/190 hp—burns 4.7–4.3 liters of fuel per 100 kilometers (50 - 54.7 mpg US) with CO2 emissions of 114–124 g/km. If the optional eight-speed Steptronic transmission is specified, these figures improve further to 4.5–4.1 l/100 km (52.3 – 57.4 mpg US) with CO2 emissions of 109–119 g/km, depending on the tire format fitted.

Prof. Armin Schnettler from Siemens’ central research department and Prof. Achim Kampker, Managing Director of StreetScooter, agreed to equip a StreetScooter EV with an innovative electronic and software architecture by end of 2014. Click to enlarge.

Siemens will equipping an electric car with a completely redesigned information and communications technology (ICT). Basically, the idea is to control a variety of vehicle functions on a uniform, centralized computer platform instead of providing every system with its own hardware and software as today.

The new ICT concept was developed by Siemens’ global Corporate Technology (CT) department and its partners in the German government-funded RACE (Robust and Reliant Automotive Computing Environment for Future eCars) project. (Earlier post.)

A team from General Motors Global Research & Development Center in Michigan has developed a new double-layered core–shell structure of polymer-coated carbon–sulfur to confine better the sulfur/polysulfides in the electrode of lithium–sulfur (Li/S) batteries and to improve the batteries’ cycling stability and Columbic efficiency.

In a paper in the ACS journal Nano Letters, they report a stable capacity of 900 mAh g–1 at 0.2 C after 150 cycles and 630 mAh g–1 at 0.6 C after 600 cycles. They also demonstrated the feasibility of full cells using the sulfur cathodes coupled with silicon film anodes, which exhibited significantly improved cycling stability and efficiency.

Renault has presented EOLAB, a new prototype which explores ways to deliver ultra-low fuel consumption. EOLAB delivers NEDC combined cycle fuel consumption of 1 liter/100 km (235 mpg US), equivalent to 22g of CO2/km. To achieve such low figures, the designers focused their efforts on three main areas: minimizing weight; leveraging aerodynamics with active systems; and using the “Z.E. Hybrid” plug-in hybrid system—the last offering all-electric trips of up to 60 km (37 miles) at speeds of up to 120 km/h (75 mph).

Conceived around a B-segment platform, the prototype incorporates around 100 new, realistic technological developments that are designed to be introduced gradually on upcoming Renault vehicles. EOLAB features materials such as magnesium and aluminium, which are extremely light and also much cheaper than titanium. Meanwhile, the notion of such a car being produced in large numbers within the next 10 years was dialed into the plan from the start.

BMW is introducing a new generation (earlier post) four-cylinder 2.0-liter diesel for its 220d Coupe and 220d Active Tourer. Coupled with the optional 8-speed Steptronic transmission, the BMW 220d Coupe now only hits the 100 km/h mark in a 7 seconds, but also attains a CO2 emission level of less than 100 grams/km. In the Active Tourer, the engine delivers combined fuel consumption of 4.5 - 4.4 l/100 km (52.3 - 53.5 mpg US) with CO2 emissions of 119 – 115 g/km).

The 2-liter diesel power unit is a member of the new BMW Group engine family. It features the latest version of BMW TwinPower Turbo technology, achieves a maximum power output of 140 kW/190 hp, while delivering a maximum torque of 400 N·m (295 lb-ft). With the standard 6-speed manual gearbox, the two-door car accomplishes an average fuel consumption of 4.4 to 4.1 liters/100 km (53.5 to 57.4 mpg US) and a CO2 level of 115 to 107 grams per km.

SwRI launching consortium to develop new dynamic engine bearing test rig

16 September 2014

Southwest Research Institute (SwRI) has announced the formation of a consortium for joint research into new technologies to evaluate engine bearings for internal combustion engines. The objective of the Dynamic Bearing Rig Consortium is to design, to demonstrate and to validate a dynamically loaded bearing test rig that can replicate the variable loads critical to how bearings perform in an operating engine under transient and steady-state conditions.

Various rig tests are used in the bearing industry for comparative material evaluation. While these tests are effective in comparing new materials and coatings against existing designs, they do not successfully replicate the engine operating environment. As such, SwRI notes, they are not useful in correlating fatigue or scuff performance to what is seen in the field.
