This paper presents a failure analysis on a failed intake valve in a gasoline engine. During an endurance test, an intake valve was broken and caused some damages on the piston. Material examinations (by a light microscope and also a scanning electron microscope) were conducted on the fracture surface of the intake valve shaft. Results showed that no pores or defects could be observed and the m...

The gas force due to the combustion in the cylinder of an IC engine will cause the piston to move with primary motion and secondary motion. The primary motion of the piston from TDC to BDC is linear in nature. This motion is desired for translation of motion of engine components. Secondary motion is due to the transverse motion of the piston while piston moving from TDC to BDC and vice-versa. T...

In this study, the performance of a single cylinder four stroke direct injection (DI) diesel engine is analyzed in the light of first law of thermodynamics. An energy balance study is carried out to quantify the various losses associated with diesel engine processes on the basis of experimental performance and emission data. The engine was fuelled with normal diesel and Jatropha Methyl Ester (J...

In a spatially periodic temperature profile, directed transport of an overdamped Brownian particle can be induced along a periodic potential. With a load force applied to the particle, this setup can perform as a heat engine. For a given load, the optimal potential maximizes the current and thus the power output of the heat engine. We calculate the optimal potential for different temperature pr...

The aim of this work is to investigate the influence of NO/SO2 on the emissions of N2O from diesel engine. A direct-injection diesel engine (model NF-19SK YANMAR) one cylinder was employed to test the emission. This engine works on fourstroke cycle and was operated at 2200 rpm by 25, 50, and 75% engine load. The experiment by three level sulfur content of fuel by adding DBDS into MDO and experi...

This paper investigates the opportunity of using almond oil as a renewable and alternative fuel source. Different fuel blends containing 10, 30, and 50% almond biodiesel (B10, B30, and B50) with diesel fuel (B0) were prepared and the influence of these blends on emissions and some performance parameters under various load conditions were inspected using a diesel engine. Measured engine performa...

Diluted exhaust from selected military aircraft ground-support equipment (AGE) was analyzed for particulate mass, elemental carbon (EC) and organic carbon (OC), SO4(2-), and size distributions. The experiments occurred at idle and load conditions and utilized a chassis dynamometer. The selected AGE vehicles operated on gasoline, diesel, and JP-8. These military vehicles exhibited concentrations...

With modernization and increase in the number of automobiles worldwide, the consumption of diesel and gasoline has enormously increased. In this experiment tri fuel concept was used according to that diesel and turpentine different proportion bled introduced in diesel engine and acetylene entre in the diesel engine through intake manifold in the diesel engine. Among the many process parameters,...

Web Usage Mining also known as Web Log Mining is the extraction of user behaviour from web log data. The log files also provide immense information about the search engine traffic at a website. This search engine traffic is helpful to analyse the ethics of search engines, quality of the crawlers, periodicity of the visits and also the server load. Search engine crawlers are automated programs w...
