Effects of varying air-fuel ratio on the performance of a theoretical Diesel cycle
This paper analyses the effects of varying air-fuel ratio on the performance of a theoretical Diesel cycle under a temperature restriction as maximum. Amount of heat addition at constant pressure is defined as a function of fuel's energy with utilising the combustion efficiency. The amount of released energy into the cylinder restricts the compression ratio. Relations between the combustion ...

Effects of combustion efficiency on an Otto cycle
This paper explains how the combustion efficiency influence the performance of an irreversible Otto cycle under conditions of varying fuel-air ratio. The irreversibility of Otto cycle comes exclusively from the expansion and compression processes. It is assumed that some fraction of the fuel's chemical energy cannot be fully released inside the engine because of incomplete combustion. Amount of ...

Evaluation of the optimum efficiency of fire tubes boilers
Three-stage pirotubular boilers using gasoil C have been studied. Two boilers were connected in parallel. The data has been obtained by means of an analyser; its probe was connected at the exit of the boilers. The operation parameters considered were the injection pressure and the number of burners. As the emission of pollutants must be within the values prescribed by legislation, these are ...

Magnetic nanopowder as effective adsorbent for the removal of Congo Red from aqueous solution
A magnetic iron oxide nanopowder (MnP), prepared by a simple and efficient combustion synthesis technique, was tested for the removal of the anionic dye Congo Red (CR) from aqueous solution. The influence of solution pH, adsorbent dose, temperature, contact time and initial dye concentration on the adsorption of CR onto MnP were investigated. It was shown that the CR adsorption was pH dependent ...

Methoxytriethyleneoxypropyltrimethoxysilane
Methoxytriethyleneoxypropyltrimethoxysilane can form covalent bonds with the polymer chains, creating a three-dimensional structure that is more resistant to degradation. Thus, it is frequently used as a crosslinking agent in polymers. Methoxytriethyleneoxypropyltrimethoxysilane provides the abilities of reducing friction between surfaces and resistance to adhesive. So, it can be used as a ...
