چکیده

The need to improve the thermal efficiency of gasoline engines used in hybrid vehicles, has led explore new solutions for reducing engine heat losses. Hence, it is important car manufacturers be able predict transfer components. Numerical methods such as CFD (Computational Fluid Dynamics) or CHT (Conjugate Heat Transfer) can assess losses through combustion chamber walls, but they are long and costly. In this regard, particularly interesting industry use simplified models, which may play a key role design stage. work 1D model integrated with 3D finite elements based on commercial software calculate single-cylinder direct injection engine. first validated, then detailed analysis performed, its results compared those full CFD–CHT simulation. Results demonstrate that approach suitable short time spatial temperature distribution solid regions an internal also yields accurate values terms performance.

Ethanol Internal Combustion Engines

Ethanol Internal Combustion Engines HIGHLIGHTS PROCESS AND TECHNOLOGY STATUS – The use of biofuels (e.g. bio-ethanol and biodiesel) in the transport sector can save significant amounts of fossil fuels and greenhouse gas (GHG) emissions. Internal combustion engines (ICEs) can run on bio-ethanol manufactured from biomass or waste through biochemical processes. Agricultural feedstock such as sugar...

Transient combustion control of internal combustion engines

This thesis addresses the problem of combustion control for automotive engines. A method is proposed to complement existing controllers, which use lookup tables based on steady-state operation. During transients, the new control method adjusts fast control variables (ignition or injection time) to compensate for deviations in the cylinder initial conditions from their optimal values due to the ...

Research needs for future internal combustion engines

Transportation is second only to industrial use as the largest consumer of energy in the US and accounts for about 60% of our nation’s use of petroleum—an amount equivalent to all of the oil the country imports. The numbers are staggering: Some 10 000 gallons of petroleum are burned in the US each second of every day. Although new energy sources are being developed and renewable fuels are emerg...
