According to the company’s admissions, in the late 1990s, Takata began developing airbag inflators that relied upon ammonium nitrate as their primary propellant. From at least in or around 2000, Takata knew that certain ammonium nitrate-based inflators were not performing to the specifications required by the auto manufacturers. Takata also knew that certain inflators had sustained failures, including ruptures, during testing.
New Opel Insignia to offer torque-vectoring all-wheel drive with Twinster system
January 11, 2017
The all-new Opel Insignia Grand Sport, arriving in the market early this year, will be available with a torque vectoring all-wheel drive system. The new Opel Insignia uses a GKN Twinster all-wheel drive system with a rear drive module that uses a twin clutch system without differential. The two clutches distribute torque between the front and rear axle and between the two rear wheels.
Torque vectoring provides intelligent control of the vehicle dynamics by sending precise amounts of torque to individual wheels; by over-speeding the outside wheel in a corner, torque vectoring can induce a yaw-moment, helping steer the vehicle. Conventional torque vectoring systems use a set of planetary gears either side of the differential to achieve only very low levels of over-speeding. Other systems use braking to achieve a similar effect—but waste energy and slow the vehicle in the process.

Daimler Buses to offer electrohydraulic power steering to reduce fuel consumption
October 19, 2016
Daimler Buses will offer electrohydraulic power steering (EHPS) to reduce fuel consumption in coming bus models. The fully integrated system replaces the conventional power steering pumps used currently in all buses with a gross weight of more than 7.5 t.
Conventional hydraulic power steering (HPS) is driven directly by the internal combustion engine via belts or gear trains with a fixed gear ratio which results in a pump speed that is directly proportional to the engine speed. To provide sufficient power for the steering in every situation, the pump must be able to deliver the full volumetric flow rate even when the engine speed is low—meaning that it is over-dimensioned for most operating situations. For this reason, higher engine speeds require a restriction of the volumetric flow rate by means of a bypass, which, however, entails unnecessary losses.

Final testing confirms ADEPT 48V diesel hybrid reduces fuel consumption 10-12% at low incremental cost
September 13, 2016
The three-year ADEPT (advanced diesel-electric powertrain) project (earlier post) in the UK set the target of developing and validating a range of advanced mild hybrid technologies with 48V “intelligent electrification” utilizing an advanced lead carbon battery. These have been applied to a Ford Focus project demonstrator which, for the first time, will be made available for public ride and drive evaluation by delegates at the Low Carbon Vehicle event (LCV2016), at Millbrook, UK.
Final testing has confirmed ADEPT’s key achievement of 10-12% reduction in fuel consumption (NEDC)—equivalent to sub-80g/km of CO2 emissions. According to the latest updated analysis of the potential cost of production implementation of ADEPT—conducted independently by Ricardo—the system would represent an incremental cost of in the region of €60 per gram/km of CO2 reduction. This is a result that makes the ADEPT powertrain architecture very competitive with other fuel economy solutions such as full hybridization, where costs of implementation can be significantly higher.

Study suggests focusing on cold starts in gasoline cars as target for emissions reduction
August 22, 2016
A new study suggests that focusing on a gasoline-fueled vehicle’s cold start is the best target for future design changes to reduce emissions of criteria pollutants. The researchers are presenting their work today at the 252nd National Meeting & Exposition of the American Chemical Society (ACS) in Philadelphia.
Although the Environmental Protection Agency (EPA) has reported that air is cleaner today than it was in the 1970s, more than 130 million people in the US still live in places where smog or particle pollution rises to unhealthful levels. Smog can cause coughing and shortness of breath, and can aggravate asthma or trigger asthma attacks. Much of this haze is formed from volatile organic compounds, or VOCs, and fine particulate matter from tailpipe emissions.

Audi developing electromechanical rotary dampers; potential for energy recuperation from suspension; 48V
August 10, 2016
Audi is developing a prototype electromechanical rotary dampening system called “eROT,” in which electromechanical rotary dampers replace the hydraulic dampers used today for an even more comfortable ride. The eROT system also offers the potential for energy recuperation from the suspension.
Every pothole, bump, and curve in the road induces kinetic energy during compression and rebound of the car’s suspension, observes Dr.-Ing. Stefan Knirsch, Board Member for Technical Development at AUDI AG. “Today’s dampers absorb this energy, which is lost in the form of heat. With the new electromechanical damper system in the 48-volt electrical system, we put this energy to use.
