||One of the main actions of preparation
and development of a 4-stroke engine consists in the modification of the camshaft. With the experience or the simulation
you can determine the new timings and the new maximum lift,
but what remains problematic is the determination of the
lift law and of the cam profile, this to maximize the
volumetric efficiency and in the meantime check out the
valve train acceleration for reliability and wear.
Thanks to the software Professional Cam
e Perfect Cam
instead you can design your cams with precision and to have the
drawing and the data for a fast realisation.
||The head ports modifications has always
been one of the most important stage in the development
of the engine. Often, however, it is possible to obtain
the optimal modifications to head ports only through
countless hours on the flow bench or relying on
expensive simulations cfd. The
instead wants to give to the tuners a simple tool that will help them to identify in advance
the appropriate changes to make to the ducts, directing
their, through appropriate fluid dynamic calculations, in the right direction for the benefit of time and costs.
||The fluid dynamic losses that there are
at the inlet of intake duct of throttle body or carburetors, limiting the effective area of passage of the same and thus penalize the maximum
volumetric efficiency possible for the engine. The reduction of these losses
is possibile with the application of cornets, but to
find the their optimal geometry is not always easy.
Thanks to the software
Intake Bellmouth Design
instead you can quickly find the most suitable geometry of the
bellmouth. Moreover, the software provides the data and the drawing of the bellmouth for an easy realisation with CNC machines.
||In the development of the engine, the interventions on
the geometry of intake and of exhaust, and on the valve
timing are essential. It's possible therefore use
formulas that help to make the sizing, but these are
unfortunately not very precise, or it's possible use
fluid dynamics simulation, but the thing is long and
requires specific knowledge, which often the tuners can
not deal. For this reason NT-Project has developed the
Four Stroke Design
which allows to have indications for the sizing of the
engine much more precise than the classic formulas, and
at the same time to have an ease and a speed of use
ideal for the technicians and the tuners who want to
quickly identify the best solutions for their needs.
||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 Balance 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 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
||The flow bench is an excellent tool to verify the
efficiency of a fluid component, often, however, the
analysis is limited to the flow rate (cfm, etc..), Which
from a point of view of the evaluation of the efficiency
is not very significant, especially when you flush
components with different areas. Thanks to the
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.
||NT-Project can also develop customized versions of software in
production, or engine software to meet specific needs, here you
can see some examples
