Combustion parameters

The study results have shown that the converted engine can operate according to the principle of HCCI in low load conditions of up to 30%. The combustion characteristics and engine operation parameters before and after conversion to HCCI mode are tested and evaluated on the engine test bed. Experimental research to quantify and assess the engine's HCCI operating mode and construct a set of control parameters for setting and widening the working regime in HCCI mode.

C2H5OH has been using as an alternative fuel for decades; HO2 also plays a pivotal role in the combustion. The kinetics and mechanism for the reaction between C2H5OH and HO2 radical have been investigated using the molecular parameters for the reactants, transition states and products predicted at the CCSD(T)//B3LYP/6-311++G(3df,2p) level of theory.

Dilution of the intake air of the SI engine with the inert gases is one of the emission control techniques like exhaust gas recirculation, water injection into combustion chamber and cyclic variability, without scarifying power output and/or thermal efficiency (TE). This paper investigates the effects of using argon (Ar) gas to mitigate the spark ignition engine intake air to enhance the performance and cut down the emissions mainly nitrogen oxides. The input variables of this study include the compression ratio, stroke length, and engine speed and argon concentration.

The results showed that the turbulent burning velocity coefficient in this case is around 1.3 when the average engine revolutions is in the range of 3000 rpm to 6000 rpm with biogas containing 80% Methane. We can then predict the effects of different parameters on the performance of the engine fueled with compressed biogas by simulation.

Internal combustion engines (ICE) are the main sources of powering for almost all road vehicles, yet many other machines too. Being under strength development for a number of years, they have already reached a relatively high level of technical excellence and now they also produce acceptable output parameters. Still, they are not devoid of drawbacks. Harmful exhaust emissions can be pointed as the most important here. This problem is the main focus of interest for automotive researchers and engineers.

1. Background of the Development The shape of gears is very attractive to the PM manufacturing process. Spur gears as well as helical gears can be shaped by compaction. The performance of gears is influenced beneath the geometrical design mainly by the material parameters tooth root strength σFE and pitting resistance σHlim. The comparison of these values from PM gears to wrought steel gears shows clearly, that PM gears can only be used in low loaded applications (Fig. 1).

Under certain conditions, lichen floristic and community analyses can be used in conjunction with measured levels of ambient or depositional pollutants accumulated by lichens to detect effects of changing air quality on vegetation. This information can demonstrate whether air pollutants cause undesirable changes in species composition or presence/absence of lichen species within terrestrial plant communities. It is important that any alternative hypotheses (e.g.

Because of the potential public health implications, the importance of toxic air pollutants in ambient air has been recognized to some degree for many years. Efforts to “regulate” human activities resulting in the production of ambient air pollutants probably date back many centuries, even as the combustion of fossil fuels and air pollution from other organized human activities began having a noticeable impact on the environment.
