DESIGN |
|
|
Simulation is fundamental in the development of a 2-stroke
engine, but unfortunately it's often inaccessible due to
complexity and cost. For this reason, thanks to over 20 years of
experience in simulation, we wanted to create the software
Two Stroke Simulator,
which on the one hand is 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. |

The losses at the entrance of the carburetor reduce the effective diameter of the carburettor and then
the intake is not exploited fully. To improve this situation it is customary to study cornets to apply to the carburetor, but often the determination of the optimal geometry is difficult to detect and you have to make several and expensive attempts. Thanks to the software
Intake
Bellmouth Design, instead you can quickly find the most suitable geometry of the cornet to maximize the efficiency of the carburetor. Moreover, the software provides the data and the
drawing of the bellmouth for an easy realisation with CNC machines. |

The shape of the reed valve causes significant fluid
dynamic losses to the fluid flow that comes from the intake manifold, therefore a part of the pressure difference generated by the crankcase is expended to overcome these losses
at the expense of the reed opening. Thanks to the software
Insert Reed Design you can study
inserts for the reed valve that improve
the flow to the advantage of performance. The software
in addition to defining the geometry of the insert, it
also indicates the processing steps for its craft realization. |

|
In the 2-stroke engine with reed valve admission, the identification of petals more adapted to the reed valve and
to the engine is essential to maximize the performance starting from the intake phase.
Often you've been forced to use the reed petals proposals on the market, without being able to take significant action. Thanks to the software
Reed Design can instead analyze the behavior of your reed
valve and study the petals most appropriate also with solutions that use with
fiber stopper or spacers interposed to obtain stiffness variables and increase the performance
on more rpm. |

The analysis of the timing and the timing area of the cylinder ports, essential to evaluate the operation of the engine and decide how to intervene in the development, often is difficult and can not be made in an easy and precise. Thanks to the software
Two Stroke Design instead you can enter the
data of your cylinder with extreme facility and precision, and then analyze the
port areas and the timing area in the engine cycle timing for each phase.
Moreover you can have advices for the development of the engine
thanks to the help of tested formulas for intake, exhaust,
blowdown and transfer. |

 In a single cylinder engine choices in terms of balance and inertia of the crankshaft engine are fundamental both for what concerns the reliability (loads on the frame, vibrations, etc..),
both for performance, in fact influence the amount of friction and then the engine power, acceleration,
shift gear, brake engine, etc.. Making appropriate choices is not always easy as they depend on characteristics of the engine,
of the vehicle and of the type of use. Thanks to the software
Crankshaft Design
instead you can quickly find the optimal solution to get the best results. |

|
In function of the characteristics of the engine and of the
vehicle, the choice of the gearbox ratios is essential to fully
exploit the potential of the engine. Equally important are the
choice of the final drive ratio, the engine speed upshift, and
the engine inertia. Finding the best solutions is not easy
because each engine and each vehicle require different choices,
but thanks to the software Gearbox Design you can easily make
the choices to get the best performance on the track. |
|
|
The study and the development of a variator is very complex, but
it is also essential to make the most of the engine's potential.
That is why we have developed the software Variator Design
that allows you to see how any intervention on the variator
influences the performance, and therefore to identify the most
suitable components, the changes to be made, and the optimal
set-up, for your needs depending on the engine and vehicle
characteristics. |

ANALYSIS |
|
|
The data acquisition systems and telemetry allow you to collect a lot of information on vehicle performance,
but what is often difficult to obtain are engine performance
(torque, power) to analyze concretely how is making it and then evaluate the optimal tuning. Thanks to the software
Virtual Dyno you can
instead easily get the curves of torque and power of
your engine, simply by rearranging the data acquired from your
acquisition system. |
|
|
The flow bench is a great tool to check the fluid dynamic efficiency of a component,
often, however, the analysis is limited to the flow rate (cfm, etc..),
that from a point of view of the evaluation of the efficiency is not very significant, especially when
you're fluxing components with different areas. Thanks to the software
Flow Analysis
instead from
the data collected from your flow bench you can really see the efficiency of the component, and then see if the
modifications have given a benefit or whether the fluid flow rate is changed just because the passage area is increased or decreased. This is crucial to
obtain a development in the optimal direction. |

CUSTOMIZED |

NT-Project can also develop customized versions of software in
production, or engine software to meet specific needs, here you
can see some examples |
