Introduction

"AMF Fuel Information System" focuses on the end-use aspects of advanced motor fuels. Performance of cars, effect on emissions and compatibility with infrastructure are included, whereas resources, production and GHG emissions are excluded. When the end-use aspects are evaluated, the complex field of engine/aftertreatment options, uncertainties of measurement methods and incomparability of measurement campaigns has to be taken into account. Priority is given to new studies; however, these represent only minor part of published studies.
Compression ignition engines are the leading power sources in heavy-duty vehicles due to high efficiency. Major part of light-duty cars are equipped with spark-ignition engines, but share of compression ignition engines is increasing. Emission control devices and engine's internal solutions have crucial effects on the exhaust emissions. Oxidation catalyst, particulate filters and selective catalytic reduction (SCR) are common exhaust aftertreatment devices today.
Evaluation of fuel properties is one tool to predict and estimate performance of fuels, including potentially harmful compounds that may arise in the exhaust emissions. Requirements for fuels are set in the legislation and standards to fuel properties and blending components, which are suspected to lead to problems on operability and general performance.
The field of fuels, engines and aftertreatment devices has changed drastically over the past years. Potential improvement in performance, exhaust emissions and health costs could be achieved with new vehicles and emission control systems. Advanced fuels may give even further benefits in end-use aspects. At the very least, advanced motor fuels shall not hinder using new technology or reasonable infrastructure.
