Influences Of AdBlue® spray targeting and mixing devices on the UWS distribution upstream of the SCR catalyst

Selective catalytic reduction (SCR) technology was introduced to diesel engines in order to meet current and future legislative requirements for lower CO2 and NOx emissions. For high NOx reduction efficiency and robust operation, a uniform reductant distribution at the SCR catalyst inlet is mandatory. With highly efficient powertrains comes a decrease in exhaust temperatures, therefore

Energy savings — Impact on CO2 emissions

With today’s brush pump technology, it is possible to reach an overall efficiency up to 25 % or a power consumption of about 120 watts (see Figure 6). The relation between electrical power and quantity of CO2 emitted will depends on the application: fuel economy, injection pump efficiency, engine efficiency, alternator efficiency and driving cycle.

Fuel Pump controller integration

The NMVEG driving cycle (NDEC) as stated earlier contains essentially driving conditions requiring a portion of max power. Controlling the Fuel Pump voltage by depending on engine load would require an electronic controller. Once this technology step is given, changing from DC technology to brushless would only increase the efficiency savings. The primary functions of

DELPHI NEW GENERATION OF FUEL MODULE The Brushless technology

Brushless type motors are commonly used in the automotive and non-automotive industry. The concept is as follows: magnet is located on the rotating part while the rotating field is generated by the coils located on the stator. Stator is a "three phases" winding topology, which means 3 electrical connections (Phase U, Phase V, and Phase

Figure 3: Example of current Delphi Fuel Fuel Module / Low pressure Fuel Pump description

The fuel module, which is located inside the fuel tank, comprises either an electrical lift pump or a suction pipe in case the High Pressure pump contains a first stage drawing the fuel directly from the fuel tank. In addition to the electric lift pump, the Fuel Module also contain a fuel level indicator, interface

STATE OF THE ART Diesel Common rail architecture

Most OEMs are only proposing in their Diesel fleet Common Rail (CR) engines, which have already experienced several optimizations: second, third and even further generation of CR. They are all following the same drivers: meeting new regulation (particles, emissions, fuel economy…) while containing system costs. The new regulation levels (Euro 6 and Euro 7) forcing

Fuel Systems for IC Engines

A prognosis about the development of the worldwide energy demand and the possibilities of the necessary supply has to take into account several factors. It is not just the availability of primary energy sources like oil, gas or coal, but also the development of the gross domestic product (GDP), inflation and energy efficiency has to
