General-These specifications are in general use and have been adopted as an SAE Standard primarily for conventional automotive type engines. This category includes passenger car and light or medium duty truck, tractor, and industrial engines, as well as some compressors. For heavy duty gasoline and diesel engine it may be necessary to depart from these

Piston Velocities and Piston Work
Aircraft Engineering and Aerospace Technology, 1950WHEN evaluating engine efficiencies, mean effective pressures or the work done by the piston in internal combustion engines or compressors, it is generally assumed that the state of the working fluid is uniform throughout its mass. From this it follows that the expression for work where P denotes pressure and V, volume, holds.

Proceedings of the 33rd Annual Computer Security Applications Conference, 2017
While software is now being developed with more sophisticated tools, its complexity has increased considerably, and, as a consequence new vulnerabilities are discovered every day. To address the constant flow of vulnerabilities being identified, patches are frequently being pushed to consumers.

Piston Vibration in Piston-Cylinder Systems
Journal of Fluids Engineering, 1980The motion of a cylindrical piston falling in a liquid filled vertical cylinder is analyzed. It is found that concentric motion is impossible and that flow induced vibration is always associated with such piston-cylinder systems. If the clearance over radius ratio is larger than a certain critical value, βcr, severe wobble and piston-cylinder contact ...

The piston ring or the piston seal?
Russian Engineering Research, 2010Improvement in the efficiency of piston compression rings is considered. By taking account of the gas dynamics in determining piston-ring geometry and developing a system of piston rings and piston seals for various internal combustion engines, their basic performance and environmental characteristics may be improved.

Tribological characteristics of piston rings in a single-piston hydraulic free-piston engine
Industrial Lubrication and Tribology, 2017Purpose A free-piston engine (FPE) is an unconventional engine that abandons the crank system. This paper aims to focus on a numerical simulation for the lubricating characteristics of piston rings in a single-piston hydraulic free-piston engine (HFPE).

Study on Piston Motion Control Strategy of Single Piston Hydraulic Free-piston Engine
2012 Second International Conference on Intelligent System Design and Engineering Application, 2012This paper investigates the piston motion control strategies of a single piston hydraulic free-piston diesel engine, which is intended to be a power supply for hydraulic propulsion systems. The Cycle fuel mass is determined by engine displacement and load.

There were a number of aircraft and engine manufacturers active in Germany in 1930s and 1940s. Some were quite well known, e.g., Messerschmitt (former Bayerische Flugzeugwerke), Focke-Wulf, Junkers, Dornier, etc. Some others were rather obscure, e.g., Hamburger Flugzeugbau, Klemmflugzeugbau, etc.

Loaded-piston gauges with self-centering pistons
Measurement Techniques, 1983This work on developing, commissioning, and operating a direct-loading machine for 1 tf (100 kN) gives rise to the following conclusions. The chain loading scheme with i0 links enables one to implement the lO-stage loading series recommended by the standards with monotonically increasing or decreasing loads.
