Effect of Octane Number on the Performance of Euro 5 and Euro 6 Gasoline Passenger Cars
Author(s): Williams, J., Hamje, H., Rickeard, D., Kolbeck, A. et al.
Abstract Research Octane Number (RON) and Motor Octane Number (MON) are used to describe gasoline combustion which describe antiknock performance under different conditions. Recent literature suggests....
Octane Requirement and Efficiency in a Fleet of Modern Vehicles
Author(s): Redmann, J., Beutler, M., Kensler, J., Luebbers, M. et al.
Abstract In light of increasingly stringent CO2 emission targets, Original Equipment Manufacturers (OEM) have been driven to develop engines which deliver improved combustion efficiency and reduce ene....
Soy Biodiesel Oxidation at Vehicle Fuel System Temperature: Influence of Aged Fuel on Fresh Fuel Degradation to Simulate Refueling
Author(s): Anderson, J., Collings, T., Mueller, S., Ball, J. et al.
Abstract An experimental study of the effects of partially-oxidized biodiesel fuel on the degradation of fresh fuel was performed. A blend of soybean oil fatty acid methyl esters (FAMEs) in petroleum ....
Injector Fouling and Its Impact on Engine Emissions and Spray Characteristics in Gasoline Direct Injection Engines
Author(s): Henkel, S., Hardalupas, Y., Taylor, A., Conifer, C. et al.
Abstract In Gasoline Direct Injection engines, direct exposure of the injector to the flame can cause combustion products to accumulate on the nozzle, which can result in increased particulate emissio....
The Effect of Near-Zero Aromatic Fuels on Internal Diesel Injector Deposit Test Methods
Author(s): de Goede, S., Barbour, R., Velaers, A., Sword, B. et al.
Abstract Internal diesel injector deposits (IDID) are now a well understood phenomenon and a standard test procedure has been developed and partially approved by the Coordinating European Council (CEC....
Accumulation Mechanism of Gasoline EGR Deposit
Author(s): Kikuchi, G., Miyagawa, M., Yamamoto, Y., and Inayoshi, N.
Abstract Exhaust Gas Recirculation (EGR) systems reduce exhaust emissions and improve fuel efficiency. Recently, the number of EGR system installed vehicles has been increasing, especially for gasolin....
A Study on the Effects of Cetane Number on the Energy Balance between Differently Sized Engines
Author(s): Li, J., Bera, T., Parkes, M., and Jacobs, T.
Abstract This paper investigates the effect of the cetane number (CN) of a diesel fuel on the energy balance between a light duty (1.9L) and medium duty (4.5L) diesel engine. The two engines have a si....
Evaluation of Anti-Knock Quality of Dicyclopentadiene-Gasoline Blends
Author(s): Al-Khodaier, M., Bhavani Shankar, V., Waqas, M., Naser, N. et al.
Abstract Increasing the anti-knock quality of gasoline fuels can enable higher efficiency in spark ignition engines. In this study, the blending anti-knock quality of dicyclopentadiene (DCPD), a by-pr....
A Study of Diesel Fuel Injector Deposit Effects on Power and Fuel Economy Performance
Author(s): Behrendt, C. and Smith, A.
Abstract Injector cleanliness is well characterised in the literature [1,2,3,4] as a key factor for maintained engine performance in modern diesel cars. Injector deposits have been shown to reduce inj....
Compatibility of Fuel System Elastomers with Bio-Blendstock Fuel Candidates Using Hansen Solubility Analysis
Author(s): Kass, M. and West, B.
Abstract The compatibility of key fuel system infrastructure elastomers with promising bio-blendstock fuel candidates was examined using Hansen solubility analysis. Thirty-four candidate fuels were ev....
Gasoline Anti-Knock Index Effects on Vehicle Net Power at High Altitude
Author(s): Vertin, K., Schuchmann, B., Studzinski, W., Davis, R. et al.
Abstract Automakers are designing smaller displacement engines with higher power densities to improve vehicle fuel economy, while continuing to meet customer expectations for power and drivability. Th....
Impact of Fuel Sensitivity (RON-MON) on Engine Efficiency
Author(s): Prakash, A., Wang, C., Janssen, A., Aradi, A. et al.
Modern spark ignition engines can take advantage of better fuel octane quality either towards improving acceleration performance or fuel economy via an active ignition management system. High....
A Chemical and Morphological Study of Diesel Injector Nozzle Deposits - Insights into their Formation and Growth Mechanisms
Author(s): Rounthwaite, N., Williams, R., McGivery, C., Jiang, J. et al.
Abstract Modern diesel passenger car technology continues to develop rapidly in response to demanding emissions, performance, refinement, cost and fuel efficiency requirements. This has included the i....
