Abstract The present research activity's major objective is to improve the performance and emission characteristics of diesel engines that burn pyro oil cashew nut shell nanoparticles. This work identifies nanoparticles should be added allow it utilized efficiently in compression ignition engines. In this experiment, two nanoparticles, Al 2 O 3 TiO , were mixed with oil. For testing purposes, c...

Climate change and the depletion of fossil fuels make it urgent to find an alternative oil-based fuels, especially in machines powered by internal combustion engines. Biomass is currently a poorly used source energy meets necessary conditions replace large part fuels. However, current engines cannot burn solid biomass specific engine needs be developed. This work proposes thermodynamic cycle bi...

Ultra-lean burn conditions (? > 1.8) is seen as a way for improving efficiency and reducing emissions of spark-ignition engines. It raises fundamental issues in terms combustion physics its modeling, among which the significant reduction laminar flame speeds increase thickness, well an increased sensitivity to local fuel/air equivalence ratio variations are essential be accounted compared conve...

burns are injuries which may require long hospitalization and may result in important impairment and disability. burn injuries are still common especially in developing countries. assessment of the epidemiology of burns is very important for introduction of preventive methods. this study was conducted in yazd to assess and describe the epidemiology of burns including its main causes, and its de...

Turbocharged CNG engines produce high NOx emission due to the fuel type and high combustion temperature. In this research, the effects of lean-burn and waste gate opening pressure threshold on NOx emission are studied theoretically and experimentally at WOT condition as well as 13-mode ECE-R49 test cycle. A code is developed in MATLAB environment for predicting engine NOx and the results are va...

Opposed rotary piston (ORP) engines have high power density and compact designs which meet the requirements of sources hybrid vehicles. Hydrogen applications to ORP can effectively decrease greenhouse gas emissions; however, hydrogen combustion in around stoichiometric ratio generated large quantities nitrogen oxides (NOx), especially for low engine speed conditions. Lean-burn as an effective m...
