2-STROKE ENGINE CLOSE EXAMINATION - A STUDY WITH 2TBASE SOFTWARE

 

NEW RESTYLING. READY!

 


MAIN FEATURES 2TBASE SEVEN

2TBASE is a simulation software by Soft-Engine for 2-stroke engines with spark plug ignition up to 500 cc (30 in3) and 20,000 r.p.m. Enter data relevant to engine, cylinder geometric layout, intake and exhaust layout, combustion, and, above all, the ports configuration (geometrical ports or any-shape ports). Moreover, interest factors like the port parameters are computed even if the simulation is not run. Data input is easy and intuitive. Results are in terms of torque and horsepower in the range of  revolutions per minute previously set. The engine model can be customised  and geometrical data, such as intake and exhaust pipes length can be modified. Moreover power and torque curves can be superposed and displayed, so that you can observe them as if you were in front of a power test bench. This software can compare up to 6 power and torque curves simultaneously. Intake by piston port and by rotary valve systems  is also included in the program. Muffler cones to be entered are  max. 8 (divergent) and max. 4 (convergent). Cylinder and ports  parameters (e.g.: time-area, specific time-area, angle area etc...) can be calculated too. Charts and graphics can be printed.

 

The software computed also the reed valve intake system; during the simulation it's possible to observe the pressures or the reed valve movement  at full screen.

 

The software is totally re-styled in the graphic aspect and several function are added. Software is compatible with Windows (Xp, Vista, Seven, Eight).

 

 

DATA INPUT

A main window is used to select the engine simulation, or to run other software about 2-stroke engine.

 

2TBase, the main window

 

There are some dialog-windows to input the data, starting by the port areas configurations:

 

PORT AREAS COMPUTING

The first thing to do is to input the port area data, because they are the most important for a good simulation. Firstly, it's possible to enable / disable the port by clicking the coresponding shape in the port areas condiguration window, adding secondary transfert port, boost, bridges etc... Later, it's possible to input the timing (the ports phases and durations), and finally each port can be directly planned giving its own shape. This shape can be a regular figure (rectangle, circle, ellipse, trapetium) or not. In this second case, it's possible to design any kind of shape by placing control point in a milimetric background, or by modifing an elliptical figure.

  Area computing for any shape port (in this example, the exhaust port)

 

 

 Area computing for the reed valve

  

   

REED VALVE COMPUTING

If there is the reed valve it's possible to input all data about reeds, petals and port stop, so the "reed valve" model can be imposed to simulation:

 

Reed valve data input

 

INTAKE AND COMBUSTION COMPUTING

Input these data to simulate the combustion during the engine simulation:

 

Intake data input

  

Combustion data input

 

EXHAUST SYSTEM CONFIGURATION

The exhaust system configurationn is most important to get a good result, so it's possible to input all muffler parts. It's possible to input up to 8 divergent and 4 convergent cones. For each part it's necessary to input diameters and lengths.

 

Exhaust data input

   

SIMULATION

After all data introduction, the software is ready to simulate the engine! During the simulation you can see the pressure curves in the cylinder.

RESULTS

 Horsepower diagram, the result of the simulation procedure

 

2TBASE gives several results, shown  by printable diagrams and charts. There is also a special chart, "Resumptive data" showing the main parameters values.

The main quantities computed by the software are: 

 

ENGINE DIAGRAMS:

  • Horsepower;

  • Torque;

 

CRANKSHAFT - KINEMATICS:

Diagrams and charts of:

  • Piston Displacement, Velocity, Acceleleration (1st order and 2nd order components);

  • Volume swept by piston (its peak value is the cyclider cubic capacity);

 

PORT AREAS:

  • Port areas (diagrams and chart);

  • Port heights (charts);

  • Max. Area, Average Area, Angle-Area, Specific Angle-area, Time-area, Specific Time-area (numeric values in the "Resumptive charts");

  • Blowdown range (numeric values in the "Resumptive charts");

 

 

DIAGRAMS, CHARTS AND OTHER FEATURES

For each ENGINE, CRANKSHAFT and AREAS FACTORS computed quantity  (the most important) the following options are available:

  • Max., min. and mean value; cursor to read all curve points;

  • Zoom, graph scale management;

  • Sizeable graphics window with complete colors management;

  • Comparison of different "2TBASE" projects (max 6 projects);

  • File section: it is possible to create directories to classify projects in a single session;

  • Long filename management;

  • Different projects  compared charts;

  • Printing page setup, with remarks,  logo and graphics management;

  • Chart of all quantities.
