THE
ENVIRONMENTALLY SAFE DRIVE (ESD)
Alternative principle of
work and the engineering solutions ensure thermal efficiency about 0.98,
effective efficiency about 0.93 in ranges of revolutions of shaft, load
performance and unsteady operational modes.
The original arrangement
and kinematic solutions have allowed to eliminate from a construction the
crankshaft, that ensures longevity, smoothness and noiselessness of work.
The drive is efficient with
the use of broad assortment of fuels and without antiknock admixtures. A
principle of work reduces toxicity of spent gases at the expense of a
diminution of unfired hydrocarbons and recombined gases.
Such drive is suitable for
cars, agricultural machines, small power stations for rural districts and
separate working points. As the nearest analog we can regard a drive of
Stirling. The offered drive differs much from the known one due to its
simplicity and originality of designing and kinematic solutions. It is possible
to take out the international patent without the rights of the publication.
A comparatively heavy
weight of the drive is superimposed by it significant advantages - high
efficiency, small discharge of fuel, soft load characteristic that does not
require availability of a gearbox, small vibrations and noise.
