     A preliminary point I will use an a certain comparison that will allow understand and logically illustrate a key
principle working of the engines SWSE which this principle is the use of spark-ignition engine with a high
compression ratio adjustment mass inlet fresh charge.

     Please imagine two of the same naturally aspirated spark ignition engines, which are identical with one exception
only, namely the first engine applied is the compression ratio 1:10 in the second the compression ratio 1:15. During
engine operation with a higher compression ratio is applied weight regulation the suction cargo so as to present in
the motor combustion detonation phenomenon no occurred, it is obtained in a way that enforces computer-
controlled throttle to cylinder filling coefficient was not higher than 0.7. If now We shall consider the work of of both
engines the original 1,000 rpm rotational speed. / Min., The first engine of compression ratio 1:10 at maximum load
(full throttle) will be characterized by a coefficient of about 0.9 while filling the engine with a higher compression ratio
1: 15 with a forced reduction of incomplete filling the by opening the throttle will be characterized by filling the
coefficient of 0.7.
It is logical to conclude that the engine with a lower compression ratio because of the suction greater servings of
cargo this case will be characterized by a higher power and a lower percentage of loss in relation to power ratio
relative to the loss of mechanical working of the system. Consider now the work of of both of the same engines at
maximum load at a speed of 3500 rpm. / Min. The first motor with the compression ratio 1:10 at maximum load (full
throttle) will be in this case characterized by a filling the coefficient of 0.7 resulting from the the natural resistances of
the intake ports for the rotational speed, while the motor with a higher compression ratio will also be 1:15
characterized by filling the coefficient of 0.7 because of of the the rotational speed you do not need inlet throttle
(throttle also open maximum of) because the natural resistance intake ducts forcing the original of the maximum the
rotational speed filling the coefficient with a value of 0.7 which is acceptable for this engine (there is no danger of
ignition detonation phenomena). Conclusion - at a speed of 3500 rpm. / Min. Both engines draw in an equal portion
fresh charge, which will feature engines at higher power and higher efficiency of energy? The construction of both
engines the same mass fresh charge identical, the loss of mechanical working arrangement almost identical.
Only with higher engine compression ratio will be be characterized by higher operating pressures and a more
effective combustion as a function crank angle. The difference in power efficiency between both motors, the
reduction of combustion in the engine compression ratio 1:15 by about 20% relative to the engine with a
compression ratio of 1:10.

     Following is a comparison engine SWSE the conventional engine (values ​​shown are hypothetical and are based
on estimated calculations based on my interpretation and my knowledge of of automotive issues - at the present
time the engine SWSE is a concept and not fully working prototype).

Surely you have noticed that the

It occurs to a large extent and
increases with increasing engine
This is a result of valve strokes of
fungi which increases the valve

effect increasing the strength of the
springs, but it entails an increase
in the energy required to ensure of

of engine operation at higher
