To carry out the investigation, a cylinder pressure model was developed based on the position of the crankshaft, engine load, engine speed, and fuel injection time. This model takes into account the maximum number of parameters involved. The accuracy of the model was verified by experimental results. The average error of the cylinder pressure, the average radical of the square of the error of t...

Fossil fuels have provided a convenient and plentiful energy source, and have been used profitably in all sectors of the global economy. However, continued reliance on fossil resources must take note of, and may even be placed in jeopardy by several factors. First, worldwide oil demand continues to increase, and replacing the produced oil is technically and politically demanding and very capita...

The article presents results of the research on use chars produced during pyrolysis residual biomass as a substitutional fuel in iron ore sintering process. Such an approach allows to implement circular economy and industrial symbiosis steel branches. effect substitution conventional coke breeze used final sinter quality emission was examined. With regard productivity, consumption, properties i...

This paper aims to expose the effect of hydrogen on combustion, performance, and emissions a high-speed diesel engine. For this purpose, three-dimensional dynamic simulation model was developed using reasonable turbulence model, simplified reaction kinetic mechanism chosen based experimental data. The results show that in enrichment conditions, causes complete combustion fuel 17.7% increase wor...

in this paper, a faster method for embedding cryptographic information in the image ispresented by expressing the concept of latent prints (steganography). data is encrypted bytwo methods before embedding to increase reliability. then they are embedded into the imageby a button, a method has been expressed to reduce potential noise impact on the wayinformation is encoded.

Context & Scale This review aims to bridge the fields of inorganic molecular chemistry, electrocatalysis, lithium-ion batteries, and chemical physics of oxides by introducing a unifying concept linking the electronic structures and electrochemical properties of transition metal oxides and complexes. In this work, by reviewing broad literature on the redox behavior of a number of Ni, Co, Fe, and...

O R G wide range of approaches have been undertaken to determine how to reduce emissions from automotive engines. in a previous TLT article, the development of the homogeneous charge compression ignition (hCCi) engine was discussed. When used in place of a conventional gasoline engine, an hCCi engine can produce a 1...

Dual-fuel (DF) operation with methanol-diesel allows to reduce CO2 emissions, increase efficiency and decrease NOx soot. This paper describes the experimental results methanol-water (MeOH-W) blends as a fuel, has three objectives: (1) whether water acts knock suppressant, enabling higher diesel substitution ratios, (2) if can be measure control engine-out emissions given its cooling effect, (3)...
