Determination of Optimal ValveTiming for Internal Combustion Engines Using Parameter Estimation Method

Thermoeconomic comparison between the performance of small-scale internal combustion engines and gas turbines integrated with a biomass gasifier

Recently, many countries have paid substantial attention to power generation from biomass gasification, particularly through small-scale plants. A number of power plant models have been suggested and analyzed; however, certainly, desirable configurations have not been identified yet. Moreover, their performances are ordinarily difficult to compare, especially owing to the fact that working ...

Turbulence-Augmented Minimization of Combustion Time in Mesoscale Internal Combustion Engines

Mesoscale internal combustion engines for a variety of new combustion system applications have dimensions that are far smaller than conventional macroscale engines, yet unlike true microscale engines allow significant mean flow and turbulence to be created in the combustion chamber by the injection process. The resulting flow allows minimization of the combustion time by augmenting flame propag...

Ethanol Fuelled HCCI Engine: A Review

The greenhouse effect and limitations on carbon dioxide emissions concern engine maker and the future of the internal combustion engines should go toward substantially and improved thermal efficiency engine. Homogeneous charge compression ignition (HCCI) is an alternative high-efficiency technology for combustion engines to reduce exhaust emissions and fuel consumption. However, there are still...

Accurate Simulation of Low-Pressure Port Fuel and Water Spray in Internal Combustion Engines; Numerical and Experimental Study

One of the solutions to reduce pollutants and increase engine power is to use water spray in internal combustion engines. In this type of engine, fuel and water sprays play an important role in engine performance. In this regard, the purpose of this study is to accurately simulate fuel and water sprays and provide optimal coefficients to achieve the best simulation results. For this purpose, th...

An investigation on the effects of camshaft surface defects on producing high-frequency noises in internal combustion engines

Valvetrain is one of the major sources of noise and vibration in IC engines. The importance of cam surface quality parameters is highlighted in the valve train mechanisms with direct sliding contact between cam and tappet. In this paper, the influence of surface quality parameters on high frequency noise producing is investigated. The roughness and waviness of some intake and exhaust camshafts ...
