LANL's Computational Fluid Dynamics expertise hails from the very beginning of the Manhattan Project in the 1940s. When the United States found itself in the midst of the first energy crisis in the 1970s, this core Laboratory capability transformed into KIVA, an internal combustion engine modeling tool designed to help make automotive engines more fuel-efficient and cleaner-burning.
In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons ( piston engine ), turbine blades ( gas turbine ), a rotor (Wankel engine) , or a nozzle ( jet engine ).
The Swashplate engine with the K-Cycle engine is where pairs of pistons are in an opposed configuration sharing a cylinder and combustion chamber. A Delta engine has three (or its multiple) cylinders having opposing pistons, aligned in three separate planes or 'banks', so that they appear to be in a Δ when viewed along the axis of the main-shaft.
25-year-old Rudolf Diesel Diesel's patent DRP 67 207. Theory and Construction of a Rational Heat Motor (German: Theorie und Konstruktion eines rationellen Wärmemotors zum Ersatz der Dampfmaschine und der heute bekannten Verbrennungsmotoren; English: Theory and construction of a rational heat motor with the purpose of replacing the steam engine and the internal combustion engines known today ...
The Scuderi engine is a design of a split-cycle, internal combustion engine invented by Carmelo J. Scuderi. [2] The Scuderi Group, an engineering and licensing company based in West Springfield, Massachusetts and founded by Carmelo Scuderi’s children, said that the prototype was completed and was unveiled to the public on April 20, 2009.
The ignition system of an internal combustion engines depends on the type of engine and the fuel used. Petrol engines are typically ignited by a precisely timed spark, and diesel engines by compression heating. Historically, outside flame and hot-tube systems were used, see hot bulb engine.
This new system was called CVCC-II. The following year, a standard cylinder head design was used, and the center carburetor (providing the rich mixture) was removed. The Honda City AA, introduced in November 1981, also used a CVCC-II engine called the ER. [3] Its use of CVCC was also known as COMBAX (COMpact Blazing-combustion AXiom).
The IRIS Engine is a design for a new type of internal combustion engine. Its inventors say that engines constructed using this design can be smaller, lighter and significantly more efficient than traditional engines of comparable horsepower and displacement .
