“…These calculations may be compared with the CVCA and VCR results below where the fractions at highest boiling ranges increased the most in ignition quality from the whole fuel. This is consistent with the results ofWeidmann et al, (1988) for full-boiling test fuels.…”

“…In contrast, Weidmann (1988) found that fuel properties have a small, measurable effect on emissions using a V W 1.67-liter, 4-cylinder engine. Hydrocarbon emissions were found to be a function of fuel cetane number, with volatility exerting a stronger influence for low cetane-number fuels.…”

“…Establishing emission limits for these substances also in diesel vehicles is imperative in the light of the vehicle fleet growth, toxicity of these compounds, and their contribution as precursors in ozone gas formation reactions in low troposphere. (Rui de et al, 2005) 3.1.2.2 Effect of diesel fuel reformulation Weitmann et al (1988) investigated the effects of diesel fuel composition on aldehyde emissions from a VW 1.6 litre four cylinder engine in a naturally aspirated and a turbocharged version. The total aldehyde content was measured using the MBTH method in FTP driving cycles.…”

Recent data indicate that, in many countries, mobile sources are responsible for the largest portion of emissions of aldehydes, ketones and certain other air toxic pollutants. These air toxic pollutants along with methane are either carcinogenic or pose significant human health threat. These pollutants also add to global warming in a substantial way. This paper gives an overview of their properties, basic chemistry and conditions of formation in internal combustion engines. Again worldwide many countries are promoting alternative fuels to tackle the crisis of traditional fuel. But the impact of this movement toward alternative fuels with respect to toxic emissions has not been well studied. Therefore, in this paper the analysis on the effects of engine operation and fuelling parameters is also reviewed with specific references in gasoline, diesel, natural gas, liquefied petroleum gas, ethanol blended petrol and Biodiesel fuelled engines. This is accompanied by the review of the studies of the performance of exhaust catalytic converters with respect to aldehydes, ketones and methane. Additionally, aldehydes, ketones and methane detection and measurement methods are summarized and analyzed from the view of their applicability to exhaust gas analysis.

“…The cetane number (CN) is one of the most signi"cant properties of automotive diesel fuel and its increase usually results in enhancing engine performance, reducing exhaust emissions, lowering fuel consumption and reducing engine noise (Kagami et al, 1984;Russel, 1989;Weidmann et al, 1988). The cetane number measurements in this series of experiments are described in Table II, where the concentration of the compounds tested in the base fuel K along with the change in CN ( CN) and the blending cetane numbers (BCN) are cited.…”

This paper presents experimental results regarding the impact of adding different tertiary amides of fatty acids to mineral diesel fuel; an assessment of the behaviour of these compounds as possible diesel fuel extenders is also included. Measurements of cetane number, cold flow properties (cloud point, pour point and CFPP), density, kinematic viscosity, flash point and distillation temperatures are reported, while initial experiments concerning the effects on particulate emissions are also described. Most of the examined tertiary fatty amides esters have very good performance and they can be easily prepared from fatty acids (biomass). Such compounds or their blends could be used as mineral diesel fuel or even fatty acid methylesters (FAME, biodiesel) substitutes or extenders. Copyright © 2000 John Wiley & Sons, Ltd.
