Pulse turbocharging, which had a long history of successful operation in sea-level installations on two-stroke-cycle gas engines, did not give satisfactory results at high altitude as evidenced by increased thermal loading and reduced load-carrying ability. Proper application of the constant-pressure system overcame these difficulties. The underlying theory explaining these results, supported by factory and field developments, is given in this paper. Start-up, operational, and maintenance experiences are given on constant-pressure-turbocharged, two-cycle, uniflow engines at high altitude.

An experimental investigation of hydrostatic extrusion through conical dies using commercially pure lead billets was carried out with two different hydrostatic pressure systems; namely, a ram-type extrusion system (with a forced predetermined extrusion rate), and an injection pump (constant-pressure) system. Pressure characteristics, flow patterns, and the cavity, piping, and dead-zone effects were investigated. Experimental pressure results for both types of pressure systems agreed well with analytical predictions. Furthermore, dead-zone, cavity, and piping effects were found to be dependent upon the semicone angle and the amount of area reduction of the billet.
