A set of explanatory diagrams with text can be displayed. You may also define a single straight cone and print the patterns of each of the pieces which, when welded together, will provide an equivalent bend section. The number of pieces and the overall bend angle are entered through the keyboard.
A MOTA engine data file may also be accessed and the pattern of each section of the expansion chamber printed. Alternatively, any one section may be selected and patterns suitable for the construction of an equivalent bend section printed. We now have a simple 2 stroke expansion chamber design program. This program is not a part of MOTA, but it has been put together by the same engineers as a starting point for those wishing to begin from scratch. It calculates the dimensions for both double and triple stage diffuser expansion chambers from a few basic engine dimensions.
Those used in this program have been chosen for petrol engines, and are in the range 50cc up to about cc per cylinder. It is doubtful these formulae would work on small capacity glowplug engines, since the exhaust gas temperature is much lower, and the engine speed is much higher.
How it all began MOTA is an engine simulation program suitable for everyone from the enthusiast to the university researcher - from the beginner racer to the professional tuner.
See testimonials. You can test your own engine and then re-test and compare your modifications - or build your ultimate engine right on the screen.
Millions of fluid and thermo-dynamic calculations are made by MOTA representing the conditions inside your two-stroke engine throughout it's complete operating cycle.
No previous knowledge of the two-stroke cycle engine is required - just input the required data and then run MOTA to set in motion this powerful process. Test your own theories on porting and exhaust pipe design; explore the limits of various intake methods; or just look for the highest power output from your own engine. MOTA will accept a single-cylinder design, which will also cater for many multi's where 2, 3 or more cylinders of the same basic layout are repeated.
Easy-to-operate, accurate and hours of fascinating results to enjoy! 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.
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..
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. Download Free PDF. A short summary of this paper. Download Download PDF. Translate PDF. Bhattacharya1, A. Basu2, S. Chowdhury3, Y. Upadhyaya4 1 B. Analysis of piston is required because of its shape and it is subjected to both structural and thermal loads.
In the present study, piston of a two stroke spark ignition internal combustion engine having maximum power of 6. The piston made up of Aluminium alloy is designed by conventional approach and then both thermal and transient structural analysis have been carried out. In order to improve the design of piston, two alternative designs have been considered by providing openings at the skirt region of the piston.
The analysis showed that this modification improved the thermal performance of the piston. An alternative design with large openings at the skirt region showed the best thermal performance.
Keywords: Piston, Aluminum , structural analysis, thermal analysis. As shown by Mon et al. In an cooling system, thermal properties of engine component Internal Combustion IC engine, it is acted upon by the materials. It was also found that the choice of material for pressure of the expanding combustion gases in the the component in the combustion chamber is one of the combustion chamber and the motion is transmitted to solutions, in order to improve engine performance.
Besides, through the piston-connecting rod assembly to the the geometry and dimension of the engine parts are also crankshaft. A piston is a major component in an IC engine considered in order to improve the engine performance.
Gudimetal and Gopinath[1] successfully The objective of the present study focusses on the design used reverse engineering to generate a CAD model of a and analysis of the piston based on the structural and damaged IC engine piston and using finite element method thermal considerations.
The use of computational fluid carried out a linear static and a coupled thermal-structural dynamics and generation of a combustion model, as carried analysis. They concluded that reverse engineering could be out by Toppo[6], has limited application in this analysis. According to them, by altering the design parameter e.
The piston considered for the present study is of a 2 stroke thickness of the crown, barrel thickness, thickness of the single cylinder petrol engine. The engine specifications are ring lands, an optimal solution to the existing design could shown in Table 1.
The most common material used for be obtained. Although other elements are Parra[3] showed that the empirical correlations to calculate present in smaller amounts, the alloying element of concern the gas-side heat transfer coefficient, could be evaluated on is silicon in aluminum pistons. Using an alloy having a a comparative basis using data from a current production composition beyond the eutectic point i.
