Experimental Investigation on Knock Characteristics from Pre-Chamber Gas Engine Fueled by Hydrogen

Energies
Hydrogen-fueled engines require large values of the excess air ratio in order to achieve high thermal efficiency. A low value of this coefficient promotes knocking combustion.

Diffusion-controlled combustion [PDF]

, 2001
We devote this brief review to some relevant aspects of diffusion-controlled combustion. After a survey of the conservation equations involved, we shall describe the Burke-Schumann limit, which is applicable when the reaction time at the flame is very ...

Vortex motion in axisymmetric piston-cylinder configurations [PDF]

By using the Beam and Warming implicit-factored method of solution of the Navier-Stokes equations, velocities were calculated inside axisymmetric piston cylinder configurations during the intake and compression strokes. Results are presented in graphical

Combustion Characteristics of a Hydrogen-Fueled TJI Engine under Knocking Conditions

Energies
The use of a two-stage combustion system in a hydrogen-fueled engine is characteristic of modern internal combustion engines. The main problem with hydrogen combustion in such systems is knocking combustion.
