Delphi’s New Key FOB Technology Helps Make Smart Phone Connectivity Available at Low Cost
DETROIT – Delphi Corp.’s new key fob technology and custom applications are offering drivers a myriad of important vehicle information delivered to their smart phones. The technology lets drivers know when to refuel or get an oil change. It can even provide a vehicle’s location.
Delphi’s key fob technology is providing low-cost smart phone connectivity using both Bluetooth and Near Field Communication (NFC) platforms. The company’s key fob designs and custom apps enable information exchange between drivers and their vehicles that is continual, reliable and convenient while giving vehicle manufacturers the ability to meet the specific information needs of different global markets.
Smart Phone Connectivity via Bluetooth Gateway Key Fob
Using a custom phone app with Delphi’s advanced key fob technology, medium-range connectivity (650 feet/200 meters or more) can now be made available to consumers without subscription fees, cellular network delays or coverage gaps. Delphi’s Bluetooth Gateway Key Fob allows users to view important vehicle information and complete often-performed tasks remotely on their smart phone or similar device.
“From receiving security and diagnostic alerts to checking a vehicle’s eco-score, our technology allows drivers to monitor vehicle statistics from their smart phone via Delphi’s key fob,” Beth Schwarting, general director, Electronic Controls, Delphi Electronics & Safety said. “Drivers no longer need to be inside their vehicles or have an internet connection to get updates on vehicle status.” A useful complement to embedded telematics/phone app solutions when a driver is out of cellular range, the system is made up of highly reconfigurable electronics and offers a remote user interface that is intuitive and user-friendly. It is also of benefit with connected telematics solutions when a driver is out of a vehicle’s Bluetooth range.
Smart Fob Enabled by Near Field Communication
Delphi’s also offers a Smart Key Fob that uses NFC to provide drivers direct accessibility to vehicle information while helping to ensure the security of data exchange. The NFC wireless standard, a read/write technology, offers both secure information transfer and a low power consumption mode. Its low-range communication profile – only 2 inches (5 cm) – helps prevent hacking while its low consumption mode helps ensure durability and reliability.
Data exchange is made possible using an NFC module integrated in the vehicle. The system antenna enables data transfer from the vehicle to the key fob, and the transferred information can be accessed by the driver via any NFC-compatible portable device that has an active display such as a smart phone. Data that can be accessed and managed includes mileage and fuel level, safety and security information (such as tire pressure), maintenance warnings and alerts, personalization features (seat, steering wheel, A/C configuration), vehicle location (GPS), driver identity, In-Case-of-Emergency (ICE) contacts and vehicle type.
Meeting Growing Market Needs
Delphi’s smart fob technology will be even more valuable as the market for hybrid and electric vehicles grows. With these fobs, drivers will be able to enhance their awareness of energy and fuel consumption and manage them more effectively and in an environmentally friendly way.

Delphi’s Ammonia Sensor Helps Diesel Manufacturers Meet More Stringent NOx Emissions Regulations
DETROIT — Delphi Corp. is the first company to develop and market an innovative technology for the automotive industry that could displace conventional products and help diesel manufacturers around the world meet stringent new emissions standards for nitrogen oxides (NOx). The Delphi ammonia sensor, which will be first produced in 2012 for a European commercial vehicle manufacturer, was showcased during the SAE World Congress, April 13 -15.
Delphi’s new ammonia sensor is first to allow closed-loop control of SCR process
Selective catalytic reduction (SCR) aftertreatment is becoming an increasingly popular choice for NOx control to help manufacturers meet diesel engine emissions requirements. And, the need for precise control of urea — an ammonia rich compound required by the SCR system — is expected to rapidly increase to meet demanding new emissions regulations. Delphi’s ammonia sensor is the first technology that allows direct closed-loop control of the SCR process, permitting the amount of urea injected into the exhaust stream to be optimized. A second key function of the sensor is to provide on-board diagnostic information for the SCR system.
Sensor allows the engine to operate with higher fuel efficiency, while meeting tailpipe NOx standards
Delphi’s ammonia sensor is intended for use in diesel vehicles equipped with an SCR system, including light-duty, medium-duty and heavy-duty diesel vehicles. It helps enable the SCR system to work at greater NOx conversion efficiencies, which allows the engine to operate with higher fuel efficiency while helping the vehicle meet new tailpipe NOx standards. It also provides manufacturers with the flexibility to potentially reduce or eliminate an expensive post-oxidation catalyst that would otherwise be needed to remove excess ammonia from the exhaust and to help enable the size of the SCR converter to be optimized. Additionally, by significantly reducing ammonia slip the sensor provides the potential for significant cost savings for high-mileage
operators who will be able to use less urea.
Delphi’s ammonia sensor helps enable new solution for diesel emissions control
The use of SCR is expected to increase dramatically in both light-duty and heavy-duty diesel applications. SCR technology is already well established in the European heavy-duty truck market and will become increasingly important in the U.S. to enable compliance with new heavy duty regulations to be mandated from 2010. SCR is also used on passenger cars in the U.S. market to help achieve compliance with Tier 2 Bin 5 regulations for light duty vehicles and is expected to increase in popularity in Europe to help manufacturers meet Euro 6 regulations to be mandated for light-duty vehicles beginning in 2014.

Delphi Liquid Cooled Charge Air Coolers Reduce Vehicle Emissions and Improve Fuel Consumption While Increasing Performance
DETROIT — A new range of liquid cooled charge air coolers (LCCACs) from Delphi Corp. will help global vehicle manufacturers of both gasoline and diesel engines produce environmentally-friendly vehicles with better engine performance. Compared to existing air-cooled units, the new coolers offer better packaging, improved engine response, faster warm-up and lower losses.
In order to combine reduced tailpipe emissions, improved fuel economy and maximum driver satisfaction, vehicle manufacturers are turning to downsized engines. Boosted by turbo- or super-charging, these engines give the performance feel of a larger engine with the emissions and fuel savings of a smaller one. However, boosting compresses the air entering the engine, which significantly increases the air temperature greatly reducing combustion efficiency and eroding the performance improvement. Delphi addresses this by introducing a charge air cooler into the intake system; Delphi manufactures a wide-range of air-cooled charge coolers and is now developing a portfolio of new liquid cooled heat exchangers that offer more flexibility in their installation.
The versatility of Delphi’s LCCAC technology also allows the coolers to be incorporated into the ducting between the turbo/super charger and the engine or integrated into the intake manifold, minimizing air-pressure losses through the cooler and improving engine bay layout. To provide vehicle manufacturers with additional packaging flexibility, Delphi’s wide range of heat exchangers can be modified for specific applications to fit any size and shape of engine.
Unlike an air-to-air charge cooler, a LCCAC requires no large diameter elastomeric tubing to route the charge air to and from the cooler, further improving packaging and eliminating large diameter connectors that can lead to warranty problems. Engine  response to sudden throttle demand is improved because of the smaller volume of intake air between the boosting device and the engine in a liquid cooled system. Additionally, the intake air stays cooler during acceleration because the liquid cooled charge cooler heats up more slowly. This higher thermal capacity also helps to limit peak NOx emissions during transient driving conditions by maintaining cooler inlet air temperatures.
Further emissions benefit is derived under cold start conditions, as coolant flow to the LCCAC can be limited to increase engine warm-up rate. On gasoline engines, during partial load conditions when engine efficiency falls due to throttling losses, coolant flow can also be limited to heat the intake air, reducing its density and allowing a greater opening of the throttle valve and,
hence, reducing the losses.
“We expect to have the first Delphi liquid cooled charge air coolers in production during 2011,” Steve Kiefer, director of engineering, Delphi Thermal Systems, Delphi Corp said.
