A Inson Cycle Engine Diagram

Ctl engineering has designed and realized a running prototype of a compact modular atkinson cycle engine.

In simple terms the atkinson cycle was designed to minimise the use of fuel during the intake stroke yet exploit the part of the cycle that generates power. A three cylinder 10 liter and four cylinder 13 liter which will be introduced. The atkinson cycle engine was patented in the united states in 1887 atkinson filed for uk.

In modern days people are taking this atkinson cycle advantage in building hybrid engines to make the engine a bit more efficient. The most common combustion engine these days is a four stroke otto cycle engine where a piston goes up and down inside a cylinder and a spark ignites a mixture of gas and air. A modern variation of this approach is used in some modern automobile engines. But the uneven strokes of the piston in his gasoline powered combustion engine fit our modern hybrid systems pretty neatly.

The atkinson engine is essentially an otto four stroke engine with a different means of linking the piston to the crankshaft. The atkinson cycle is designed to provide efficiency at the expense of power density. The atkinson cycle engine is a type of internal combustion engine invented by james atkinson in 1882. And european patents a couple years earlier.

So that is why this atkinson cycle is the extended otto cycle. The isentropic expansion of this otto cycle is further allowed to proceed to the lowest cycle pressure in order to increase the work output. The atkinson cycle is designed to provide higher efficiency at the expense of power density. Same goes for an atkinson cycle engine so heres a quick refresher of the process.

Atkinson cycle atkinson engine. For two engines of equal displacement volume the one with an otto cycle would produce the greater net work and.
