The flow characteristics, combustion temperature, ignition characteristics, emissions under different oxygen jet design and jet spacing were simulated and compared.
The problem of controlling spark ignition engine emissions during the coldstart period is addressed by designing a model-based MIMO sliding mode controller.
Apart from the absorbance of water vapor which could be determined semi-quantitatively (due to the effects of severe pressure broadening at high pressures and the ignorance of the exact temperature distribution after ignition), the emissions from the flame (broadband, 1 10 μm) and a gas inhomogeneity index were recorded.
This study enables the calculation of species transport and mixing phenomena and the simulation of ignition, combustion and emission formation in industrial furnace.
Specifically: achieving very low residual gas contents to mitigate against frictional ignitions and fugitive emissions; the means to accelerate gas drainage to accommodate mine schedule changes; and to enable pre-drainage of coal reserves with very low permeability.
The ignition times and propane emissions are compared.
We present an extensive data set based on high speed chemiluminescence imaging and exhaust gas sampling showing the characteristics of the time-averaged trajectory, width of the flame, flame standoff (or ignition) location, and NOx emissions over a momentum flux ratio range of 0.75 < J < 240.
Why is it almost unheard of for a corporate figure to make the moral case, that pushing bad product---salmonella-tainted food, a faulty ignition switch, a cheat emissions device---is simply wrong?
This paper discusses analytically and provides data on the effect of compression ratio, equivalence ratio and engine speed on the engine performance, emissions and pre-ignition limits of a spark ignition engine operating on hydrogen fuel.
In 1982, for most markets, Honda fitted a new capacitor discharge ignition (CDI) system to replace the earlier contact points ignition, thereby helping to meet emission standards in markets such as the US.
