Example power cycle of the cryogenic (e.g., liquid air) Dearman piston engine. Source: Dearman Engine Company. Sources of low-grade waste heat include power stations to factories to vehicle engines. Click to enlarge. Among the transportation uses of liquid air outlined in the report are: Prime mover.
Bladon suggests that in an hybrid vehicle application, with no water-cooling system, oil or catalytic converter, the Micro-Jet engine can provide vehicle weight savings of up to 15%—with a consequent reduction in fuel consumption and carbon emissions—compared to a piston engine. Earlier post.).
The engine can be adapted to run any combustible gas or liquid as fuel. Advanced Engine Technologies was incorporated in 1996 to commercialize the OX2, with automotive racing pioneer Carroll Shelby on its Board of Directors and involved in the engine development. Tags: ConceptEngines. OX2 in a test rig.
The engine components are contained within a sphere. The first cycle is a “conventional” combustion engine process using a combustible fuel with the crankless (i.e., The engine is classified as a turbine, says Jim Andrews, vv-tec’s President, because the use of the sinus discs make the engine into an impulse turbine.
The Scuderi Engine is a split-cycle design that divides the four strokes of a conventional combustion cycle over two paired cylinders. Intake air is compressed in the compression cylinder and transferred to the power cylinder for combustion. a more efficient internal combustion engine.
Each of the two linear generators in the system is equipped with a mechanical spring, which is used for storing mechanical energy in the power stroke and releasing mechanical energy in the compression stroke. Furthermore, natural gas will be investigated as the fuel of the system. —Huang et al.
