A newly developed heavy duty diesel engine in dual fuel mode of operation has been studied in detail. The main fuel would be natural gas and diesel oil as pilot injection. The importance and effects of mixture preparation and formation through ports, valves and in cylinder flow field with different swirl ratio and tumble on diesel combustion phenomena is an accepted feature which has been studi...

This paper is devoted to study the effects of pressure drop in heat exchangers on the dynamics of a free piston Stirling engine. First, the dynamic equations governing the pistons as well as the gas pressure equations for hot and cold spaces of the engine are extracted. Then, by substituting the obtained pressure equations into the dynamic relationships the final nonlinear dynamic equations gov...

A dual loop organic Rankine cycle (DORC) system is designed to recover waste heat from a heavy-duty compressed natural gas engine (CNGE), and the performance of the DORC–CNGE combined system is simulated and discussed. The DORC system includes high-temperature (HT) and low-temperature (LT) cycles. The HT cycle recovers energy from the exhaust gas emitted by the engine, whereas the LT cycle reco...

In this study a heat exchanger is designed for cooling exhaust gas and an experiment is carried out to investigate the effect of Exhaust Gas Recirculation (EGR) temperature on destruction of the fuel’s availability due to combustion processes in IDI diesel engine cylinder. To serve this aim an exergy analysis is conducted on the engine cylinder which provides all the availability terms by which...

Today, the prices of fossil fuels such as gasoline and diesel are skyrocketing, oil depletion air pollution major challenges for us auto industry in particular. Natural gas has known a potential alternative fuel internal combustion engines because its advantages octane number, which is higher than that gasoline, low heat value comparison with safety use. This paper presents study on influence s...

Metal–organic frameworks (MOFs) are promising materials for storing natural gas in vehicular applications. Evaluation of these materials has focused on adsorption of pure methane, although commercial natural gas also contains small amounts of higher hydrocarbons such as ethane and propane, which adsorb more strongly than methane. There is, thus, a possibility that these higher hydrocarbons will...

The necessity for decrease in consumption of conventional fuel, related energy and to promote the use of renewable sources such as biofuels, demands for the effective evaluation of the performance of engines based on laws of thermodynamics. Energy, exergy, entropy generation, mean gas temperature and exhaust gas temperature analysis of CI engine using diesel and karanja methyl ester blends at d...
