Unconventional gasoline engine designs Motortrend listed some engine designs that might be used in future. Interesting read. Scuderi Split-Cycle--An engine where half the pistons are optimized for the task of intake and compression, while the other half are tailored to combustion and exhaust duties. The Scuderi Group, LLC - The Technology - Animations APT OPOC--That's Opposed Piston, Opposed Cylinder. A boxer with a twist: there are two pistons on in each cylinder, driven apart by combustion. And it's a two-stroke. Advanced Propulsion Technologies, Inc. Reg Tech Radmax Rotary--Instead of pistons, or a simple three-lobed rotor, the Radmax uses 12 vanes that move up and down following a wave profile, creating 24 separate chambers. Sounds like a lot of friction, but who knows? Reg/Regi Technologies Inc. Pivotal Engine--Here's an elaborate concept for delivering the smooth, dense power of a two stroke, while overcoming its reliability and emissions problems. High Power Density Pivotal Engine by Pivotal Engineering Ltd - Christchurch, New Zealand Cyclone Engine--The steam engine comes of age. Stanley, eat your heart out. Cyclone Technologies, The Cyclone External Combustion Engine invented by Harry Schoell Slider Engine-A so-called Scotch-Yoke design. Welcome - Slider Engine Technologies MCE-5 Engine--An approach for achieving variable compression-ratio that replaces the standard piston connecting rod with an elaborate toothed rocker type design. Lots more moving parts than a standard engine... MCE-5 Development |
