The use of energetic nanoparticles offers a promising means of adjusting the reactivity of liquid fuels for enhanced combustion stability in next generation propulsion systems. This work outlines the development of a novel aerosol rapid compression machine (RCM) for studying the impact of energetic nanoparticles on reducing the ignition delay of liquid fuels, and a proof-of-concept demonstratio...

Ammonia (NH3) is recognized as a carbon-free hydrogen-carrier fuel with high content of hydrogen atoms per unit volume. Recently, ammonia has received increasing attention promising alternative for internal combustion engine and gas turbine applications. However, the viability fueling future devices several barriers to overcome. To overcome challenge its low reactivity, it proposed blend high-r...

Abnormal combustion occurrences in compression ignition engines are one of the main causes of engine failures, which severely affect the continuity of transportation operations. The detection of these occurrences may help to take measures to minimize the engine failures and increase engine life. In this work, we implement a machine learning system for abnormal combustion detection system in a s...

The work presented in this paper is an attempt to evaluate the exhaust emission characteristics of a hydrogen-ethanol dual fuel combination with different percents of hydrogen substitutions (i.e. 0-80 % by volume and of 20 % increment ) at three different compression ratios of 7:1, 9:1 and 11:1. Experimental investigations have been carried out on a computer interfaced with; four-stroke cycle, ...

Cyclopentane is a suitable naphthene, or cycloalkane, in palette for multi-component gasoline surrogate fuels due to its presence market and relevance alkyl substituted cyclopentanes also present. However, the previous oxidation studies of cyclopentane have primarily focused on neat mixtures. Blending with dimethyl ether this work therefore serves inform our understanding of, improve predictive...

Abstract Ignition delay time measurements for multi-component natural gas mixtures were carried out using a rapid compression machine at conditions relevant to turbine operation, equivalence ratios of 0.5–2.0 in ‘air’ the temperature range 650–1050 K, pressures 10–30 bar. Natural comprising C1–C7 n-alkanes with methane as major component (volume fraction: 0.35–0.98) considered. A design experim...

operating an engine with homogeneous charge compression ignition (hcci) technique is a promising technique to lower nox and pm emissions of engines while achieving high efficiency and lower fuel consumption. nevertheless, applications for hcci are still limited due to the absence of a definite means to control ignition timing and narrow operating region. a single cylinder diesel engine with com...

For a future HCCI engine to operate under conditions that adhere to environmental restrictions, reducing fuel consumption and maintaining or increasing at the same time the engine efficiency, the choice of the fuel is crucial. For this purpose, this paper presents an auto-ignition investigation concerning the primary reference fuels, toluene reference fuels and diesel fuel, in order to study th...
