Limits of Internal Combustion Engines Efficiency

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 ...

Prospects of Using Osmotic Phenomena in Solutions of Thermosensitive Polymers to Improve the Efficiency of Internal Combustion Engines

The feasibility of heat engines, coupled with an internal combustion engine and designed to increase the coefficient of efficiency of hydrocarbon or other chemical fuels, was considered. The prospects of the use of osmotic phenomena in aqueous solutions of thermosensitive polymers in order to improve the operation of heat engines were shown.

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...

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

Power and efficiency lim its for internal combustion engines via methods of finite-time thermodynamics

“In selecting an idealized process one is always faced with the fact that the simpler the assumptions, the easier the analysis, but the farther the result from reality” (Ref. 1, p. 23). The more assumptions we make, the farther we are likely to be from reality. On the other hand, detailed, realistic models for internal combustion engines are difficult and expensive to compute and analyze.2 If w...
