Turbocharging is already a key part of heavy duty diesel engine technology. However, the need to meet emissions regulations is rapidly driving the use of turbo diesel and turbo gasoline engines for passenger vehicles. Turbocharged diesel engines improve the fuel economy of baseline gasoline engine powered passenger vehicles by 30-50%. Turbocharging is critical for diesel engine performance and for emissions control through a well designed exhaust gas recirculation (EGR) system. In gasoline engines, turbocharging enables downsizing which improves fuel economy by 5-20%.

The adverse health effects of carbonaceous nanoparticle have been demonstrated for a range of carbon nanoparticles originating from different pollution sources. Stringent particulate number (PN) emission regulations have resulted in significant efforts on PN reduction in vehicles during realistic driving conditions. The main source of the PN emission in GDI engines are the diffusion flames caused by the locally fuel rich zones on the piston surface and the injector tip. The carbon deposition can be a result of low-temperature chemistry pathways of alkylperoxy (RO2) and ketohydroperoxide (QOOH) radicals or the high temperature thermochemical decomposition of the fuel through pyrolysis. This presentation focuses on the effects of the fuels and injector designs on the formation of the deposits and consecutively particle number emissions.

The choice of fuel quality in state-of-the-art combustion engines is affecting the entire fuel system in a vehicle. Most critical and sensitive parts are the injectors since even minor irritations may cause significant effects on the combustion process and emissions of the engine. Fuel and fuel additive suppliers need appropriate tools to ensure that their products are neither harming nor disturbing any of the components of the fuel injection system. For Diesel fuels, various standardized test methods are already available, but there´s a lack regarding gasoline fuel performance testing tools. The new test method described is able to show positive or negative effects of gasoline fuels on direct injection nozzles after a short running time and in an early stage, before impacts on power and driveability could be realized by the driver of a car.
