Gasoline Engine Combustion—Turbulence and the Combustion Chamber

SAE Technical Paper Series, 1981
<div class="htmlview paragraph">A research programme has been carried out to investigate the effects of operating gasoline engines with different combustion systems. The results showed that at high compression ratios (13:1) compact combustion chambers allowed an increase in compression ratio of between 1 and 2½ numbers for a given fuel quality ...

Thermo-swing insulation to reduce heat loss from the combustion chamber wall of a diesel engine

International Journal of Engine Research, 2019
Cooling heat loss is one of the most dominant losses among the various engine losses to be reduced. Although many attempts to reduce it by insulating the combustion chamber wall have been carried out, most of them have not been successful.

The Quiescent Combustion Chamber

Journal of Fluids Engineering, 1931
Abstract The term “quiescent” is originated as describing more accurately than “non-turbulent” the condition of the combustion chamber in some fuel-injection engines at the time of injection of the fuel. Such a combustion chamber is considered quiescent if the movement of the air has no appreciable effect on the distribution of the fuel ...

Aerodynamics of Combustion Chambers for Aeronautical Engines

1996
The aerodynamics of combustion chambers for aeronautical engines is studied by means of a compressible Navier-Stokes solver without chemical reactions. The three-dimensional (3-D) code is designed for the simulation of complex geometries by introducing non orthogonal curvilinear coordinates. The implicit solver, which is based on the scalar approximate

Stability of the combustion process in elastic combustion chambers

Journal of Applied Mechanics and Technical Physics, 1972
High-frequency instability phenomena in rigid combustion chambers have been studied theoretically in [1–3]. This phenomenon is attributed to the interaction between the combustion processes and combustion-product fluctuations in the chamber. One of the possible mechanisms of formation of high-frequency instability is examined in [3], where the ...
