nowadays, utilization of blended fuel in internal combustion engine is one of main topics in vehicle industries. the synergy effect will be highlighted when the potential of each fuel is employed and the engine performance will improve consequently.  in this research, the laminar flame speed of methane (main component of reference fuel for natural gas) and isooctane (main component of reference...

This paper describes an investigation in which a fuzzy control paradigm was applied to a small spark-ignition gasoline-fuelled internal-combustion engine, to achieve regulation of the fuel injection system. The control system determined the amount of fuel required from a fuzzy algorithm that used the engine speed and manifold air pressure as input values. The parameters of the fuzzy system cons...

An experimental and numerical investigation on the effect of swirl on the motion of coal particles in the near-burner region of a versatile multi-fuel swirl-stabilised laboratory burner of total thermal input of 100kW, has been performed. The burner was designed as a scale model of a lOMW coal burner operating in a cement rotary kiln, produces flames of different aerodynamic characteristics, an...

The thesis presents a complete framework for the design of an individual cylinder air-fuel ratio (A/F) controller that aims to further reduce the exhaust emissions of modern automotive gasoline engines. It is well known that this type of controller relies on a correct estimation of the A/F of the individual cylinders. Otherwise, the control system can become unstable. Therefore, the conditions ...

These investigations aim to validate the applicability of a concept for fuel-air-ratio measurements by laser-induced fluorescence (FARLIF) at elevated temperatures. For the commonly used model fuel isooctane with the fluorescence tracer toluene the FARLIF applicability was confirmed with an excitation wavelength of 266 nm for fuel-air mixtures with λ ≥ 0.2 at pressures above 1.5 bar and tempera...

In this study, a 3D combustion chamber was simulated using FLUENT 6.32. Aims to obtain accurate information about the profile of the combustion in the furnace and also check the effect of oxygen enrichment on the combustion process. Oxygen enrichment is an effective way to reduce combustion pollutant. The flow rate of air to fuel ratio is varied as 1.3, 3.2 and 5.1 and the oxygen enriched flow ...

This paper puts forward one kind of air-fuel ration control method which integrates improved Elman neural network with normal PI control. It constructs a model of the single LPG electro-plating engine and simulation platform for air-fuel ration controlling with GTPower software which seamless connect to Matlab/Simulink based on JL1P39FMB single cylinder engine and develop the electronic fuel-in...
