Delphi Showcases Advanced Powertrain and Vehicle Electrification Technologies at 18th Aachen Colloquium

Delphi technologies will help automotive manufacturers meet emissions targets while enhancing performance and increasing fuel economy.

Release Date: October 02, 2009

Aachen, Germany — Today on average, a vehicle emits 154g of CO₂ per km of travel. By 2020, automakers will be required to meet the European Commission CO2 fleet-average target of 95g/km. This 2020 CO₂ target is subject to review by January 2013 and could be even more stringent. Delphi Corp. is developing products that will help automakers meet these requirements while still enhancing performance and increasing fuel economy.

The 18th Aachen Colloquium of Automobile and Engine Technology, being held Oct. 5-7, 2009 will give engineers from around the world the opportunity to learn more about Delphi's latest powertrain technology developments. Delphi will present a technical paper on light-duty diesel fuel injection and showcase an array of technologies including a range of advanced gasoline and diesel engine management systems, fuel handling systems, powertrain cooling solutions and hybrid and electric vehicle products.

"Our latest powertrain technology introductions complement major engine design trends and are driven by requirements for reducing emissions levels and fuel consumption, as well as other market factors," explains Ron Pirtle, president Delphi Powertrain Systems and president Delphi Europe, Middle East & Africa. "Delphi has the technologies that can address the challenges of tomorrow, from advanced diesel and gasoline engine management systems to products for hybrid and electrical vehicles."

Delphi presenting paper on future trends in light duty diesel fuel injection systems

On Tuesday, Oct. 6, 2009, Delphi's Dr. Detlev Schoeppe, technical director for Delphi Diesel Systems, will present a technical paper titled, "Future trends in light-duty diesel fuel injection systems." The paper will detail Delphi's developments in fuel injection equipment and control strategies for light-duty diesel engines, including the recent introduction of a diesel common rail system that is particularly well suited to the requirements of the advanced low emission engines now under development. "In this paper, we will demonstrate how the new Delphi Direct Acting Diesel Common Rail System meets the needs of future diesel powerplants that are being designed for high boost, high power density, low emissions, and low fuel consumption," says Dr. Schoeppe. The Delphi direct acting diesel injector makes best use of the characteristics of multilayer piezo-ceramic actuators: high force and speed in efficient packaging. The direct acting injector uses piezoelectric material to produce nozzle needle motion when an electrical voltage is applied. The near instantaneous response of the piezo actuator to electrical input provides the key to delivering rapid changes of force to the nozzle needle. The elimination of the conventional hydraulic servo mechanism provides maximum injection control for optimal emissions and powertrain refinement. The technology is also ideal for stop-start applications due to its zero leakage design, which enables quick restart by maintaining a stable rail pressure at engine stop.

The co-authors of the technical paper include:

• Derk Geurts — chief engineer, Diesel Common Rail System — Delphi Diesel Systems in Bascharage, Luxembourg
  
• Dr. Rainer W. Jorach — chief engineer, common rail pumps — Delphi Diesel Systems in Gillingham, UK
  
• Dr. Nebojsa Milovanovic — manager combustion, NVH and fuels, advanced Diesel Engineering, Delphi Diesel Systems in Gillingham, UK

Delphi's display at Aachen Colloquium

During the Aachen Colloquium of Automobile and Engine Technology, the Delphi Direct Acting Diesel Common Rail System will be showcased together in booth 38 with the following technologies:

• Gasoline engine management system with Delphi's Spray Stratified Gasoline Direct Injection Multec® 20 Injector and Multi Charge Ignition system
  The new spray stratified gasoline direct injection (GDi) system from Delphi reduces CO2 emissions and delivers the performance needed for premium engines at a significantly lower cost than conventional piezo technology. With solenoid technology that delivers outstanding spray performance, Delphi's spray stratified GDi system improves fuel economy while reducing engine noise and harmful emissions. Due to the use of conventional solenoid-actuation, the Multec 20 Injector driver hardware is the same as for homogenous gasoline direct injection applications: therefore the electronic control unit (ECU) can also be used without modifications. This technology is helping manufacturers meet more stringent future CO₂ standards by improving engine efficiency, is ethanol compatible and helps reduce engine noise. To further increase the operating range and improve fuel economy on stratified GDi engines, Delphi has developed a Multi-Charge Ignition System. The system features a single coil-per-cylinder control and fires the spark plug quickly and multiple times per combustion event to enable optimized combustion. The Multi-charge Ignition ensures therefore initiation of robust combustion and compensation of fuel spray variation. As a result, Delphi's MultiCharge Ignition provides an array of benefits for GDi, but the emission control may be the most valuable over the long run. Indeed, cold start is an area where emissions can really be lessened, and the Multi Charge takes advantage of this window to decrease emissions immediately.

• Fuel handling and evaporative emissions systems with the new Delphi Brushless Fuel Pump
  An increasingly important strategy for efficiency improvement is to reduce the parasitic losses associated with engine ancillaries. Delphi's new fuel pump, due to become available by 2012, uses a next-generation brushless motor architecture and delivers reliable, uninterrupted fuel flow at system pressure. It also delivers high efficiency, improved durability, wide-ranging fuel compatibility (gasoline, diesel, alcohol mixes and even contaminated field fuels) and a 1-2g/km CO₂ reduction compared to conventional fuel pumps. With Delphi's Brushless Fuel Pumps, power consumption is reduced by approximately 36 percent (or more, depending on application). The reduction in power consumption contributes to an estimated fuel economy improvement of 0.2 mpg (0.12 l/100 km).

• Hybrid and electric vehicle technologies
  Development of economical, environmentally friendly vehicles is important to the auto industry's future. Building on more than 70 years of automotive electronics experience, Delphi is focused on reducing the cost of hybrid power electronics while, designing in market-leading functionality and reliability. We consider the rigorous electrical requirements of connection systems and wiring thermal management needs in our designs. Key power electronics products include battery pack systems, inverters and DC/DC (direct current to direct current) converters.

• Powertrain cooling systems
  After the air compression process that occurs in a turbo- or super-charged engine, cooling the engine intake air with a coolant-to-air heat exchanger offers many benefits over conventional air-to-air charge air coolers. The flexibility of Delphi's Liquid Cooled Charge Air Cooler designs allows the coolers to be incorporated into the ducting between the forced induction device and the engine or integrated into the intake manifold, minimizing the under-hood packaging impact and the air-pressure losses through the cooler. LCCAC's eliminate the large diameter elastomeric tubing used to route the charge air to the air-to-air charge cooler and the large diameter connectors that can lead to warranty problems. Engine response time during acceleration is improved because of the smaller volume of air between the induction device and engine and the high-transient thermal capacity of the liquid cooled system. This higher thermal capacity also helps to limit NOx peaks during transient driving conditions by maintaining cooler inlet air temperatures. For cold starts, coolant flow can be limited to increase engine warm-up rate and reduce the time for the catalytic converter to reach lightoff temperatures. During partial load conditions, coolant flow can also be limited to reduce air density allowing a greater opening of the throttle valve, which helps to reduce engine-pumping losses. Additionally, Delphi's wide array of heat exchangers can be modified to fit any size engine allowing for greater automaker flexibility and packaging.
