Design Data for “Cocktail Shaker” Cooled Pistons and Valves

SAE Technical Paper Series, 1965
<div class="htmlview paragraph">Cocktail shaker cooling is the commonly used term to describe heat transfer in a reciprocating hollow cylinder partially filled with a liquid. The sodium filled valve is a widely used application of this heat transfer concept.</div> <div class="htmlview paragraph">This paper presents information that ...

Modeling of Gas Cooling and Condensation in a Piston Expansion Machine

Journal of Engineering Physics and Thermophysics, 2004
A model of gas cooling and condensation in a piston expansion machine has been developed with allowance made for formation of nuclei of the liquid phase and growth of droplets as well as for real thermophysical properties. Internal heat release related to phase transition is taken into account in the adiabatic equation.

Experimental and Numerical Analysis of the Piston Cooling Jet’s Performance

ASME 2010 10th Biennial Conference on Engineering Systems Design and Analysis, Volume 3, 2010
Recently, with development in the output power and material cost efficiency, the value of thermal and mechanical stress on many engine parts such as piston is increased. On the other hands, the strength of aluminum alloys used for piston manufacturing decreases with temperature. So, for lightweight pistons, the strength reduction should be minimized to

Cylinder Cooling for Improved Durability on an Opposed-Piston Engine

SAE Technical Paper Series, 2012
<div class="section abstract"><div class="htmlview paragraph">The cooling system design for a two-stroke, opposed-piston (OP) engine is substantially different from that of a conventional four-stroke engine as the opposed-piston engine requires efficient cooling at the center of the cylinder where the heat load is highly concentrated.

Analysis of KZB axial piston pump's self-cooling

2010 5th IEEE Conference on Industrial Electronics and Applications, 2010
This paper presents a totally new kind of pump, called KZB pump, which has highly efficiency in self-cooling. Compared with other type of pumps, it has a great advance in self-cooling. The conclusions have been proved by several industrial experimental results. KZB pump, made according to the principles of double-end with oil axial piston pump, and its

Numerical and Experimental Investigation of Oil Jet Cooled Piston

SAE Technical Paper Series, 2005
<div class="htmlview paragraph">Thermal loading of diesel engine pistons has increased dramatically in recent years due to applications of various advanced technologies to meet low emission and high power requirements. Control of piston temperatures by cooling of pistons has become one of the determining factors in a successful engine design. The

Numerical Simulation of Piston Cooling With Oil Jet Impingement

Journal of Heat Transfer, 2016
Convective heat transfer of an impinging jet is numerically evaluated for piston cooling process. A circular jet of subcooled engine oil that impinges normally onto the inner surface of the piston for an engine operating at normal condition is considered in the study.

Vehicle Piston-Engine Two-Phase Cooling Systems

SAE Technical Paper Series, 1993
<div class="htmlview paragraph">Prior-art two-phase systems for cooling automotive piston engines have several handicaps which have been responsible for them not having been mass produced to date. Those handicaps are identified, and the salient distinctive features of a new technology which eliminates those handicaps are listed.

Total Cooling of Piston Engines by Direct Water Injection

SAE Technical Paper Series, 1970
<div class="htmlview paragraph">A method of cooling piston engines by direct injection of a fluid into the combustion chamber is described. Significant changes in power performance, fuel octane or cetane number requirements, exhaust emission quality, engine life, and engine configuration can be expected from injection cooling.</div> <div
