 Thank
you for your interest in DynomationTwoStroke™ designed for Windows98/XP.
Introduction
DynomatonTwoStroke is a DOS-based simulation that was originally released in
the mid-1990’s. A great deal of time and effort was expended in the
development of this comprehensive wave-action simulation (by several racers,
engine designers, two-stroke experts, and university professors expert in
engine-simulation technology). The businesses and individuals that purchased
the original Dynomation 2 Stroke program were pleased with the capability
and accuracy of the software. But because of the limited worldwide activity
in two-stroke engine development, program sales were limited and further
development was curtailed.
Now, Motion Software, Inc., has released an updated
version of DynomationTwoStroke that lets users install and run the program
under any version of Windows. Support for Windows not
only makes the program easier to use, but it also allows the growing number
of two-stroke enthusiasts to use this powerful simulation on Windows
platforms.
Why Does This Program Rely On DOS?
DynomationTwoStroke (under the surface) continues to use the DOS-based API that exists in
Windows98/XP to execute program code and create screens, menus, and graphs
(see screen images below). Why? The
answer to that question is easy:
The prohibitively high cost of conversion to Windows!
While two-stroke engine development is on the rise again, the worldwide
interest in a professional two-stroke engine simulation is still limited.
The cost to convert this program into a full Windows program (like our
Dynomation-5, four-stroke simulation) would prevent it from ever being
released! But that doesn't mean that it lacks capability.
DynomationTwoStroke is a comprehensive and easy-to-use simulation! We
guarantee it!
DynomationTwoStroke In A Nutshell
DynomationTwoStroke is a full-cycle simulation, meaning that it calculates
the complete fluid-dynamic, thermodynamic, wave-dynamic, and frictional
conditions that exist inside the cylinders and runners throughout the entire
360 degrees of the two-cycle process. It keeps track of the pressure waves
moving in the intake and exhaust systems and their effects on port/pipe
pressures and flow. The program performs hundreds of millions of
calculations at each rpm test point throughout the engine-analysis process.
Despite internal program complexity, the simulation is straightforward and
easy to use. Wtih DynomationTwoStroke, you'll build and test
engines in no time! You can depend on this package to produce solid,
accurate predictions of engine performance characteristics.
Look
Inside A Running Engine—View and Analyze Intake and Exhaust Flow And
Pressures!
DynomationTwoStroke lets you peer inside a
running engine! It reveals–otherwise invisible–pressure waves and mass flow
in cylinders, engine passages, and expansion chambers. This simulation
accurately predicts power, torque, and many other engine parameters. Even
more importantly, it show you where you should focus your efforts to
optimize performance!
DynomationTwoStroke can model a wide variety of
two-stroke engines:
-
Number of Cylinders: 1 to 3 firing into joined chambers;
unlimited firing into individual chambers
