A MEMS glass membrane igniter for improved ignition delay and reproducibility
Sensors and Actuators A: Physical, 2017Abstract A MEMS igniter with improved ignition characteristics and reproducibility is described. A glass wafer was selected as the igniter material for high membrane structural stability. To improve the reproducibility of the igniter, the membrane was designed to realize a flat surface and uniform thickness, which are essential factors for ...

Ignition delay in multifuel mixtures
Combustion, Explosion, and Shock Waves, 2007Methods used to calculate the ignition delay (induction time) of combustible systems consisting of several individual fuels are discussed. A modification of the Arrhenius equation for multifuel mixtures is proposed, which improves the agreement between numerical and experimental data. The method proposed is analyzed by an example of two-fuel systems on

Ignition delay characteristics of methane fuels
Progress in Energy and Combustion Science, 1994Abstract A comprehensive literature search and a series of shock-tube experiments were undertaken to determine the ignition delay times for mixtures of methane with ethane, propane or butane, and for a typical natural gas fuel. Ignition delay experiments were conducted at equivalence ratios of 0.45–1.25 for temperatures 1300–2000 K and pressures 3–15

Ignition delay of microplasmas at atmospheric pressure
2009 IEEE International Conference on Plasma Science - Abstracts, 2009Micarowave field breakdown conditions in gases are important whenever using plasma in pulsed mode. The plasma properties during the steady state regime are different from those during the ignition time.

Ignition Delay Evaluation of Ethanol Blends in Compression Ignition Engines
SAE Technical Paper Series<div class="section abstract"><div class="htmlview paragraph">Currently, several studies are being carried out to replace diesel oil with alternative fuels in compression ignition engines. Ethanol is a strong candidate, thanks to its extensive feedstock, low emissions and low cost.

An approach of droplet ignition delay time
Heat Transfer—Asian Research, 2008AbstractWhen a droplet is suddenly injected into a high‐temperature environment, the droplet self‐ignition phenomenon occurs. A simple model, based on the temperature history of target gas mixture of which the equivalent ratio is equal to 1, was proposed to predict the droplet ignition delay time in this paper. This approach clearly divides the droplet

Ignition Delay for Atmospheric Pressure Microplasmas
Contributions to Plasma Physics, 2009AbstractThe ignition process in microplasmas is characterized by time resolved microwave reflection coefficient measurements, using a specially equipped vector network analyzer. We measured the time between the switching on of the microwave power and the onset of the plasma state in air at atmospheric pressures. The delay time decreases from approx.

Ignition delay of composite solid propellants
Combustion and Flame, 1977Abstract Ignition delay of phenol-formaldehyde composite propellants was measured by a hot plate technique. The activation energy for the preignition reactions has been computed using the Arrhenius type expression for ignition delay.
