The 2-Stroke engine possesses magic... this we all know, any person who has engine knowledge knows it... But WHY?

The answer is in the nature of the engine itself.... An explosion for each crankshaft rotation, lightweight materials, few components, dynamics of the gases and sound....

The 2-Stroke exhaust plays a fundamental role, in the attainment of performance values, for the fact that it receives the burnt mixture and accumulates it, later to return to the entrance of the cylinder... this phenomena is given to the fact of at the moment of each explosion, the gases arrive at the end of the exhaust to the speed of the sound (supersonic), for initiating its jib wave there and still pushing the cool mixture inside the cylinder again and there being burned in the following explosion.

All this dynamics, allows that a direct relation exists between the cylinder and the exhaust, in terms of flows, areas, gas passage speed and PRESSURE of the same ones; for this reason, to get a high power of a 2-Stroke engine, these cool and burnt gases will be had to obtain one high pressure of all, in a game of tasks to a highly speed.... Only this will be able to create power and to take off left of from this wonderful engine.

But... the magic of the 2-Stroke... what it is? In the reality it’s the exponential character that this engine can have, as a 4-Stroke does not obtain - from there the 2-Stroke engine is excellent for power creation, ideal for light machines, and the 4-Stroke more vocationed for torque, the ideal one for heavy machines.
