Software Four Stroke Design to tuner and to develop intake system - exhaust system - engine head - four stroke engine

How it works?

The Four Stroke Design software with the insertion of only the fundamental data of the engine allows you to analyze the efficiency of the intake and exhaust geometries, in function of the engine valve timing, and to quickly calculate the geometries or the valve timing amelioratives to optimize the performance of the engine in based on your needs.

INTAKE and EXHAUST GEOMETRIES ANALYSIS

By simply inserting the main dimensions of the current geometries, and the valve timing of the engine, the software calculates how the waves pressure generated from the intake and the exhaust system are effective according to the valve timing and engine operating speeds.

You can then quickly see for which engine speeds the current geometries are optimized and whether these are in line with your performance needs.

CALCULATION OPTIMAL INTAKE and EXHAUST GEOMETRIES

Based on the development work that you want to perform and the performance needs that you want to achieve, the software calculates the intake and the exhaust geometries that allow you to maximize the performance in a specific operating range. In this way it will be easy to work on the geometries to increase the torque and the power just where you want it.

The software provides a complete sizing:

INTAKE HEAD DUCT DIAMETER

INTAKE MANIFOLD DIAMETER and LENGTH

INTAKE BELLMOUTH DIAMETER and LENGTH

EXHAUST VALVE DIAMETER and MAX LIFT

EXHAUST HEAD DUCT DIAMETER

EXHAUST MANIFOLD PRIMARY LENGTH

DESIGN OPTIMAL INTAKE and EXHAUST GEOMETRIES

In addition to the calculated geometries, the software also allows you to simulate the behavior of other geometries to find the compromise that best meets your needs throughout the engine operating range.

The same can be done by keeping the intake and exhaust geometries fixed, and by evaluating how the behavior of the engine changes proving different valve timing.

VARIABLE INTAKE GEOMETRY DESIGN

The software also allows you to study the behavior of variable intake geometry. In fact, by inserting how the length varies as the engine speed changes, it shows how the efficiency of the waves pressure is modified and therefore the possible advantages that can be obtained.

HEAD DUCT GEOMETRY ANALYSIS and DESIGN

In addition to the optimization of the engine waves pressure, the reduction of the fluid dynamic losses is the other aspect on which to intervene to maximize the performance. Usually this work is done only with the help of experience and with many hours at the flowbench, unfortunately, however, to reach an improvement solution often is necessary to proceed by trial with so much waste of material and with the unknown of not having achieved the maximum. Thanks to the Four Stroke Design software, it is possible to quickly analyze the fluid dynamic losses of the intake head ducts and to simulate the changes that you want make, seeing before they are even realized if they can be improved or not. In this way it will be possible to avoid material waste and immediately orientate the changes in the correct direction.

INTAKE BELLMOUTH DESIGN

The Four Stroke Design software, in addition to calculating the main dimensions of the intake bellmouth geometry, also calculates the profile that it must have in order to minimize the fluid dynamic losses. The software can therefore be used both to obtain the dimensions of the intake bellmouth, both to create intake bellmouth of different sizes which, however, have the optimum profile to reduce fluid-dynamic losses.

At the end of the calculation the software creates a TXT file with the coordinates of the profile, and a 2D drawing in DXF format of the intake bellmouth that can be manipulated in CAD-CAM systems to proceed directly to the realization.

As you have seen from this brief presentation the Four Stroke Design software is a complete tool that allows to the technician and to the engine tuners to have all the main indications to proceed with the development of the engine in the correct direction, thus being able to quickly maximize the engine performance by intervening on all the key aspects that influence torque and power.
