They also separate exhaust gasses and cooling water till they exit the riser because if water finds its way to the gas chamber, owing to a leakage in the water jacket, it will sweep into the engine cylinder and seize the piston with rust.
The second major piece of equipment is the water jacket furnace.
A new method of creating the desired undercut closed deck geometry while using conventional HPDC tooling (no loose or lost cores) relies on casting dams the full depth of the water jacket channel (Fig.
The specially designed water jacket is said to achieve excellent heat exchange efficiency.
Six plastic mold packages (1-in-1 type) and the water jacket are soldered via insulated substrates.
It also features the thermal protection of a water jacket with none of the hassle, standard ISO5 chamber HEPA air filtration, and optional 2-hour dry [H.sub.2][O.sub.2] chamber sterilization for total contamination elimination in a fraction of the time of heat-based cycles.
A three-section water jacket was applied to the intake side, center and exhaust side of the cylinder head, and a two-section water jacket was applied to the upper and lower parts of the cylinder liner.
Figure 1 shows the FE model of the cylinder structure and water jacket. Since high temperature and stress gradients are anticipated in and around the bridge area of both the water jacket and cylinder structure, these sensitive regions are meshed with high resolution (i.e., the element aspect ratio is approximately 2.0) to precisely capture the physical behaviors occurred on the solid-fluid interface.
This feature dramatically reduces the size and weight of the motor by eliminating the concentric steel tubes of the water jacket surrounding conventional water-cooled motors.
Typically, a water jacket surrounds the furnace's firebox heat exchanger and heated water is circulated to the home or other structure through insulated underground pipes.
