Compact taillight LEDs, wear-resistant powertrain valve material, Indycar windscreen

Auto sales finally got back above pre-recession levels in 2014 with August sales reaching a seven-year high. After six long years, sales levels have matched 2007’s pace. More importantly, several research groups expect 2015 continue to grow. Today’s Motor Vehicles allows marketers direct access to this healthy industry with continued growth.

Synios P2720 CR light-emitting diode (LEDs) allow bright, fog-penetrating light inside combination taillamps. Monochromatic LEDs have not traditionally been suitable for rear fog applications because they lose about 50% of brightness in certain environmental conditions. The primary solution, increasing the number LEDs, increased cost. More importantly, it required more space at a time when automakers are consolidating multiple light types (brake, signal indicator, reverse) into single units.

The Synios P2720 CR LED loses about 10% brightness in some conditions, remaining bright enough to pierce fog and provide location warnings to nearby drivers.

Wear-resistant powertrain material

Increasing sales of consumer electronics and electric vehicles are stressing the world’s cobalt supplies, forcing automakers and other industrial users to seek alternatives. A sintered-steel material for powertrain components such as turbocharger wastegate bushings, exhaust-gas recirculation (EGR) valves, and valve seats reduced cobalt use without compromising wear resistance.

Powertrain components must withstand temperatures from 0°C to 1,000°C, making the tribology (sliding characteristics) challenging. Engineers studied alloys containing as much as 54% cobalt to identify how the material improved component tribology. A wear-reducing tribolayer formd on cobalt-heavy materials but not on cobalt-free ones. However, the material didn’t need to be more than half cobalt to get that layer.

FM-T88A is a sintered steel with 17% cobalt content, meets tribology, quality, machinability and manufacturability requirements.

Racing windscreen

The Aeroscreen ballistic, canopy-like windscreen adds wind protection for Indycar racecars. The polycarbonate-laminated ballistic windscreen is attached to a titanium frame. The entire Aeroscreen assembly can be fitted on or removed from an NTT Indycar series vehicle in less than 15 minutes.

The screen includes an interior anti-reflective coating, an anti-fogging device using an integral heating element, and up to eight exterior tear-offs that can be removed during pit stops if the screen gets dirty. At 17.3 lb (7.8kg), the windscreen can withstand a 2 lb pound object striking it at more than 220mph.

The titanium frame weighs 27.8 lb (12.6kg) and can withstand 34,000 lb (15,422kg) of force.
