Numerical simulation of combustion characteristics and emission predictions of methane-air and hydrogen-air mixtures in a constant volume combustion chamber using multi-point laser-induced spark ignition

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2021
Lean-burn combustion using higher spark energy can enhance the combustion characteristics and emission performance. A laser is electrodeless with a high energy ignition source and can achieve multi-point ignition easily.

A study of heat flux in a constant-volume combustion chamber

Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2003
In the production of internal combustion engines, there has been a move towards the development of high-performance engines with fuel economy, lighter weights and smaller sizes. These trends help to answer problems related to thermal load and abnormal combustion, etc., in these engines.

Microwave Enhancement of Lean/Dilute Combustion in a Constant-Volume Chamber

SAE Technical Paper Series, 2019
<div class="section abstract"><div class="htmlview paragraph">High dilution engines have been shown to have a significant fuel economy improvement over their non-dilute counterparts. Much of this improvement comes through an increase in compression ratio enabled by the high knock resistance from high dilution.

Spray combustion of Jet-A and diesel fuels in a constant volume combustion chamber

Energy Conversion and Management, 2015
Abstract This work investigates the spray combustion of Jet-A fuel in an optical constant-volume combustion chamber under different ambient initial conditions. Ambient temperature was varied at 800 K, 1000 K, and 1200 K and five different ambient O 2 concentrations were used, spanning 10–21%.

Fuel spray and combustion characteristics of butanol blends in a constant volume combustion chamber

Energy Conversion and Management, 2015
Abstract The processes of spray penetrations, flame propagation and soot formation and oxidation fueling n-butanol/biodiesel/diesel blends were experimentally investigated in a constant volume combustion chamber with an optical access. B0S20D80 (0% n-butanol, 20% soybean biodiesel, and 80% diesel in volume) was prepared as the base fuel.

Analysis of the Current Signature in a Constant-Volume Combustion Chamber

Combustion Science and Technology, 2013
Identifying charged species and their relative concentrations as a function of initial mixture composition, temperature, and pressure can play an important role in the diagnostics and control of combustion devices. This article aims to identify important charged species and their temporal variation in a spark-ignited methane/air mixture using the ...
