Two Stroke Simulator
Simulation is fundamental in the development of a 2-stroke
engine. There are various simulation programs available on the
market, from the more sophisticated ones, which are often very
complex and expensive, to the simpler ones, which however,
although not very easy to use, are not very precise. For this
reason, thanks to over 20 years of experience in simulation, we
wanted to create a product which on the one hand was very easy
to use, and on the other provided consistent results to carry
out a first important step of optimizing the ports (dimensions
and timing), and the geometry of the exhaust muffler |

How it works?
|
The purpose of the software Two Stroke Simulator is to give to
technicians, mechanics, and tuners a tool that helps them to develop
the 2-stroke engine in the desired direction. As we know, the
2-stroke engine, if on the one hand it is very simple from a
construction point of view, is very complex from a fluid-dynamic
point of view, therefore when you want to carry out interventions to
improve the performance of the engine, proceeding by trial and error
often does not lead to the desired results. Over the years,
development aid formulas have been developed, after when the level
of the engines is grew, it became essential to use simulation
software. On the market you can find very complex and expensive
programs, which require high skills to use them, and more accessible
programs, which however often doesn't combine simplicity and
precision.
With Two Stroke Simulator we've wanted to create a product that on
the one hand was very easy to use, and on the other provided
consistent results to carry out a first important step of optimizing
the ports (dimensions and timing) and the geometry of the exhaust
muffler.
This has been possible by setting in the software predefined models
for scavenging and combustion, and focusing the attention on the
thermo-fluid dynamic calculation of the engine. In fact, scavenging
and combustion are two very difficult aspects to simulate, and even
with the most sophisticated calculation models, ofter are necessary
experimental tests to calibrate the models as best as possible,
therefore the complexity of the program would have increased
considerably, without but be sure of being able to obtain consistent
indications for these areas too.
This choice allows you to have a simulation program that on the one
hand requires very little data to carry out the calculation, and on
the other allows you to obtain those fundamental results to make all
the evaluations useful for understanding how to modify the timing,
the dimensions of the ports, and the geometry of the exhaust
muffler, to improve the torque and power curves in the desired
direction.
In summary, the use is very simple, you must insert into the
software the geometric characteristics of the engine and of its
components and carry out the simulation calculation. At the end the
software will directly show the torque and power curves that the
engine can theoretically provide with the characteristics entered.
This will be the reference from which to start to test the effect
that can have on the performance the modifications that you plan to
make to the engine.
In fact, you can easily insert into the software the modification
that you intend to make, and by carrying out a new simulation, at
the end you will directly see the comparison of the torque and power
curves, between the initial solution and the modified one, it will
therefore be easy to understand whether the modification is
successful or not, in the desired direction.
Thanks to the software Two Stroke Simulator, you will therefore have
a fundamental tool for preventively testing the modifications to the
timing and the dimensions of the ports, and to the geometry of the
exhaust muffler, which you intend to make to the engine. It will
therefore be easy for you to identify the modifications of
development on which to proceed to improve the engine performance in
the desired direction.
