Experiments were conducted to evaluate the performance of a high grade low heat rejection (LHR) diesel engine with air gap insulated piston, air gap insulated liner and ceramic coated cylinder head [ceramic coating of thickness 500 microns was done on inside portion of cylinder head] with different operating conditions [normal temperature and pre-heated temperature] of crude pongamia oil (CPO) ...

While EER (Exhaust Energy Recovery) has been widely pursued for improving the total efficiency and reducing CO2 emissions of internal combustion engines, the maximum regenerated power from the exhaust energy has been proposed and calculated in terms of endoreversible cycle. In this paper, based on the experimental data of an EER system installed on a light duty gasoline engine, the exhaust ener...

Incomplete burning of the fuel and high emission in the engine were the major problems in using the petrol as a fuel. In this Experimental study, the effects of Diethyl Ether, petrol fuel blend investigated on four stroke four cylinder SI engine for analyzing the performance and combustion characteristics. The tests were performed while running the engine at speeds of 1500&1000 rpm and at four ...

In this experimental study, the effect of creating an air jet inside the combustion chamber by establishing an air-cell inside of the piston body at different injection timings in a DI diesel engine has been studied at 2000 rpm and full load operation. The performed tests include studying the Soot and NOx emissions, combustion and performance parameters. The obtained experimental results show t...

In this study, various percentage of DEE was added to the optimum selected ethanol-diesel blend (D-E10) and optimized its blending ratio to overcome the poor ignition quality of ethanol when utilized in a single cylinder DI diesel engine. Some physicochemical properties of test fuels such as heating value, viscosity, and density and distillation profile were determined in accordance to the A...

We describe and evaluate the performance of a parallel search engine that is able to cope efficiently with concurrent read/write operations. Read operations come in the usual form of queries submitted to the search engine and write ones come in the form of new documents added to the text collection in an on-line manner, namely the insertions are embedded into the main stream of user queries in ...

In this paper, the control scheme of a Liquefied Petroleum Gas (LPG)–diesel dual-fuel engine with electronic control is illustrated, the external characteristics and load characteristics of the LPG– diesel dual-fuel engine and the diesel engine are compared and analyzed. The experimental results show that, compared with diesel, the output performance of dual fuel is not reduced, while smoke emi...
