01. Designing an H H O Generator system in collaboration with Thermo-electric Generator
On this Thesis it’s trying to introduce a solution which can be used to existing vehicles which would give solutions to Fuel efficiency, exhaust gas emissions and Global warming. Since the HHO generator is a method that has been used in many Europe countries it is actually new for a country like Sri Lanka. Even though the use of HHO generator makes a considerable increase of the fuel efficiency still the vehicle is wasting the engine generated power to the environment as waste heat. It is found that about 30% of the engine generated power is dissipated to the environment as heat. Researches show that it actually effects Global warming. Therefore the introduction the thermo electric generator to regain that waste heat into electricity, which will be sufficient to power up the HHO generator which would require of 300W at its maximum efficiency and to eliminate alternator load.
According to the user reviews of the HHO generator only by it, self and with researches done with tail-pipe emissions with and without exhaust gas emissions shows significant results which will undoubtedly give better results and lower the exhaust gas heat and emissions with collaboration with the Thermo electric generator. The introduction of the total system in to a vehicle with conventional I C engine, it is expected to reach its efficiency from 25% to at least 40%.

02. DESIGN OF LPG COOKING STOVE WITH IMPROVED
LPG cooking stoves are investigated in order to improve the thermal efficiency. Existing designs were taken to the account to identify governing parameters. Relations between theseparameters have been developed numerically in order to predict affect in efficiency level.More extensive studies were done in an effort to improve thermal efficiency by recoveringheat from flame radiation. The efficiency levels of the existing cooking stoves are in therange of 50%-60%.Heat transfer effects were investigated since most of heat losses arehappened in the process of heat transferring. Existing model has been checked with theexperimental setup and simulated with Computational Fluid Dynamic (CFD) software.Improvements were introduced to existing design and simulated with the CFD. After the analysing results with existing design improvements were finalized.
The main objective of this project is to come up with an automatic tire pressure control system that can easily be retrofitted into any off-road vehicle and design futuristic improvements that can be implemented on new cars allowing the automatic tire pressure control to be one of the standard features
The current work involved the design, advancement and testing of a coconut Dehusker that will be able perform better than the previously implemented units overcome the drawbacks of the previously reported implements. The design and developmental stages called for a closer look at the scale and direction of the dehusking forces and their generation method. Particulars of an effortless, powerful and efficient hydraulic dehusker unit, financially beneficial to laborers and producers, are given here. Comparative assessment of this unit in relation to those reported in the literature is provided. Test results and assessment of the present unit in both laboratory and field conditions are also reported. The Safety measures are included. The unit can dehusk approximately 65 coconuts per hour compared with about 38 nuts per hour by a skilled labour using the spike method. It can be operated by unskilled laborers. Cost benefit analysis signify that it should be commercially throughble.
05 Rubber Roller mill design
The Rubber two roll Roller Mills Are Used for Rubber Sheet Industry for Rubber Sheet Manufacturing Process. Mill Consist of Two Horizontally Mounted Steel Rolls/ cylinder which were rotating toward each other. Gap of the Cylinders can be adjust according to product. The Designing based on Engineering Mechanics & Machine Design and Some polymer Theories. The Calculation was started from fundamental theories to advance Engineering Concepts. The Critical Point of design and development were identified and will be presented through images & CAD Drawings.
06 Arduino Based Security System
The idea of the project was to create a security system that has the ability to sense and detect an intruder and then give an output. This was chose mainly to protect the households or business places of people from thieves or any other person who wishes them and their property harm. This system was designed for the normal people who can’t afford security systems since they are expensive. It can be marketed and sold to normal people since the manufacture and design cost of the project is low.
The design was created with the use of a PIR sensor as the input. Then the input signal will travel to the Arduino Board (controller) with the use of wires. Then the Arduino board will send a signal to the GSM module which will in turn either send a message or a call. This is the basic summary of the design. The reasons for choosing these components are shown below and lots of research was carried out during this selection process. After the creation of codes and hardware a testing stage was carried out. This showed how the system works and how efficient it is. Then the conclusion and a further development was created.
