A rapid compression machine study of hydrogen effects on the ignition delay times of n-butane at low-to-intermediate temperatures

Fuel, 2020
Hydrogen effects on the ignition delay of n-butane were investigated through a rapid compression machine (RCM) experiment and numerical analysis. The experiment was done by varying compression pressures (20 and 25 bar), equivalence ratios (0.5, 1.0, and ...

Knocking Phenomena in a Rapid Compression and Expansion Machine

SAE Technical Paper Series, 1992
<div class="htmlview paragraph">In this study, a rapid compression and expansion machine(RCEM) with a pancake combustion chamber was designed to investigate fundamentally on the knocking phenomena in spark ignition(S.I) engines. This RCEM is intended to simulate combustion in an actual engine.

Studies of fuel injection into a rapid compression machine

Combustion and Flame, 1981
Abstract An opposed-piston rapid compression machine has been fitted with a single-shot diesel injection system. The ignition of fuel sprays has been studied over a range of experimental conditions, using decane or blends of decane with lower cetane quality aliphatic and aromatic basestocks.

Soot Formation Study in a Rapid Compression Machine

Journal of Engineering for Gas Turbines and Power, 2005
A rapid compression machine was used to study the soot formation process under diesel enginelike conditions. The apparatus creates accurately controlled conditions at the end of compression (uniform mixture, temperature, and well-defined mixture composition) and, by decoupling chemistry with mixing, provides an unambiguous data interpretation for ...

Experiments in Stratified Combustion with a Rapid Compression Machine

SAE Technical Paper Series, 1978
<div class="htmlview paragraph">The foundation for engine performance and emissions models is a phenomenological description of the combustion process. In this work, high speed movies and analysis of rapid compression machine experiments have been used to develop an understanding of the mechanisms that control combustion rates in the Texaco ...

Studying the chemistry of HCCI in rapid compression machines

International Journal of Vehicle Design, 2007
The rapid compression machine is an ideal tool to investigate the chemistry of the HCCI engine as important factors controlling both devices are the same. There is no tool that describes, meaningfully, the physical and chemical processes occurring in one of the simplest research tools, the rapid compression machine and typically, processes are ...

Ignition of an iron bed in a rapid compression machine

Combustion, Explosion, and Shock Waves, 2011
A pointwise semi-empirical mathematical model is proposed, which ensures an adequate description of experimental data on the delay of ignition of a bed of iron particles in a rapid compression machine as a function of the ambient temperature.

Study of Homogeneous Charge Compression Ignition Using a Rapid Compression Machine

SAE Technical Paper Series, 2001
<div class="htmlview paragraph">The purpose of this study is to explain the characteristics of homogeneous charge compression ignition. n-Heptane, which has the same cetane number as diesel fuel, was chosen for the fuel. A rapid compression machine was used to clarify the effects of air-fuel ratio, O₂ concentration, and ...
