Significant waste heat recovery technologies have been developed to recover exhaust heat and turn it into useful energy such as in downsizing the engine or to regain the auto-electricity. Extensive work and research in energy recovery have been identified in the automotive sector; therefore the main objective of this paper is to assess each waste heat recovery technology based on current develo...

An interesting issue “whether the factual search result is better than the satisfactory one?” is discussed in this paper, and all effort is to illustrate the publicly recognized conception “the supreme satisfactory result is optimal” could lead Information Retrieval astray. By contrast, we propose a new hypothesis “the factually result should be the optimal although sometimes unsatisfactory”. T...

The limited fossil fuel resources along with the increased public concerns about pollution levels have increased the need for alternative fuels for use in internal combustion engines. This study is to investigate the variation of the engine performance and exhaust emissions of a spark ignition engine. A spark ignition engine running with gasoline and gasoline blended E5, E10 and E20. Effects of...

In this study, effect of adding in SiO2 nanoparticle in base fluid (water) in car radiator is investigated experimentally. Radiators are compact heat exchangers that optimized and evaluated by considering different working conditions. Car\'s cooling system, plays an important role in vehicle\'s performance, consists of two main parts, known as radiator and fan. Radiators are compact heat exchan...

To study the feasibility of using two edible plant oils as diesel substitute a comparative study was made. Oils were exacted from the seeds of soyabean (Glycine Max, Family: Leguminoceae) and sunflower(Helianthus annuus, Family: Asteraceae/Compositeae). Oils were esterified (butyl esters) before blending with pure diesel in the ratio of 10:90, 15:85, 20:80, and 25:75 by volume. Pure diesel was ...

in this literature, a combined method has been employed to simultaneously reducesmoke (soot) and oxide of nitrogen (nox) and maintain the performance parameters of dieselengine. this includes creating an air jet by designing an air-cell inside the piston body, advancedinjection timing and using cold exhaust gas recirculation. the tested engine was an mt4.244engine that worked as natural aspirat...

Natural gas-diesel dual fuel combustion is a beneficial strategy for achieving high efficient and low emissions operation in compression ignition engines, especially in genset application heavy duty diesel engine at rated power. This study aims to investigate a dual fuel engine performance and emissions using premixed natural gas and early direct injection of diesel fuel. Due to the different r...

Aircraft engine performance trend monitoring and gas path fault diagnostics are closely related technologies that assist operators in managing the health of their gas turbine engine assets. Trend monitoring is the process of monitoring the gradual performance change that an aircraft engine will naturally incur over time due to turbomachinery deterioration, while gas path diagnostics is the proc...
