The present paper aims to discuss the quality characteristics of Jet Fuels used in the Greek market in comparison with fuels used in other countries and to evaluate jet fuels along with diesel and biodiesel on a diesel engine. To establish the quality characteristics for Jet Fuels of the Greek market, fuel samples were collected from the local refineries on a regular basis, thus monitoring the fuel quality fluctuation over time. JP8, along with diesel and biodiesel, were used alone and in mixtures on a single cylinder stationary diesel engine. Emissions and volumetric fuel consumption were measured under various loads.

The objective of this work was the assessment of aliphatic amines and tertiary dialkyl-amides as lubrication additives or extenders, on ultra - low sulfur diesel fuels. In order to evaluate the influence of two types of nitrogen compounds on the lubrication properties of ultra - low sulfur diesel fuels, nine distillation fractions produced by atmospheric distillation of a hydrotreated diesel fuel, were used as the base fuels. Five aliphatic amines and two tertiary amides were used as lubricating additives at five different concentrations i.e. 0.5, 1.0, 2.0, 4.0 and 6.0% by volume, on the nine base fuels. Tribological experiments were carried out on the High frequency Reciprocating test Rig (HFRR). The wear results showed that only four of the five aliphatic amines used, provide satisfactory HFRR mean wear scar diameter (WS 1.4) of less than 460 microns, and at the concentration levels of 1-2% by volume. The concentration levels below 1 % by volume had no effect on the fuel lubricity.

This paper describes some of the recent work carried out in our laboratory regarding the effects of novel oxygen and nitrogen containing compounds on the antiknock quality of unleaded gasoline and their effects on some other gasoline properties. In particular, the research included Research Octane Number (RON) measurements and the evaluation of the effects of the most effective antiknock compounds on Dry Vapour Pressure Equivalent (DVPE), distillation temperatures, aromatic content, olefins, and oxygen content. Emphasis was given in studying chemical structures that can be derived from renewable raw materials. The compounds tested included substituted phenols, furan derivatives, aliphatic amines, various amide structures and Mannich base phenols. Methyl t-butyl ether (MTBE), the most widespread oxygenate currently used in gasoline, was used as a yardstick for assessing the quality of the compounds tested.
