In an opposed-piston engine, the mechanics and thermodynamics involved are complex. Changing the design offers unique challenges. Through access to the Titan supercomputer at the Oak Ridge Leadership Computing Facility, Pinnacle Engines discovered a design concept that met its technical goals. Now, Pinnacle Engines is building a prototype

The present invention relates to the "Magnetic pistons engine", hereafter called "Maps engine" or "RAT engine" or "engine" that works on the principle of magnetism. It can be used to perform

Building on over 15 years of R&D, LiquidPiston provides a power solution that can scale to address the needs of the $400B internal combustion engine market and is a key enabler for emerging mobility technologies including electric cars, urban aircraft, and drones. The company is focusing on military and aerospace markets, whose propulsion and power generation segments represent large application opportunities for LiquidPiston.

The working principle of the free piston engine is a two-stroke engine cycle, using the linear motion of pistons sliding in a cylinder. The piston is driven by gas pressure and other forces on the pistons and, hence, this engine functions similar to a mass spring system ( Fredriksson and Denbratt, 2004 ).

Internal combustion engines provide outstanding drivability and durability, The engine consists of a fixed cylinder and a moving piston.

A piston (or reciprocating) engine is a device for converting the heat energy of a fuel into mechanical energy, by internal combustion. The principles which govern the relationship between pressure, temperature. and volume. in a gas are stated in the laws of boyles' and Charles', and these principles are applicable to the operation of a piston

05/27 · Aluminium 86.3 to 82.5%. The coefficient of expansion is actually only about 2% less than that of pure aluminum, but this improvement, combined with good war and heat-resisting qualities makes the alloy a variable one. 2. Invar Strut Pistons. In this type of piston, Invar is an alloy containing 36% nickel and 64% iron.

A piston is a disc that reciprocates (up and down) inside the cylinder. At the time of the combustion process of the engine, the energy that comes out of the expanding process, transfers that energy into mechanical energy.

Enginetech piston sets have superior size and weight grading within each set. Most Enginetech piston are decked 0.010" to 0.020" to compensate for oversized bores and head/deck milling. Enginetech pistons are manufactured with state of the art materials to match OE requirements. We offer cast aluminum, hypereutectic, and forged applications.

While levels of airborne lead in the United States have declined 99 percent since 1980, piston-engine aircraft that operate on leaded fuel are
