Team UKM-Solar Car
In order to highlight solar energy as one of the main alternative energy implemented, UKM-SOLAR CAR has made a prototype car, MYNUCAR4. MYNUCAR4 considered an important factor which is efficiency of photovoltaic cells where the efficiency is 17% and the weight is about 1150 g / m². Solar radiation will produce peak radiation at the equator measuring approximately 1000 W/m2. If the solar cells directly facing the sun, then the total maximum output power that can be produced is 348.5W. Weight distribution of the car directly affects many vehicle features such as handling, acceleration, traction and the components life. If the weight of the car is not distributed properly, there is a chance where the wheel of car will slip rather than rotating. Weight distribution for MYNUCAR4 will be focused on the middle of the car and will be balance by the weight of the components in other parts. Fabrication of MYNUCAR4 divided into two parts, the car body and chassis. For the solar car body, fiberglass materials used and the order is modified by using tricycle frame to emphasis lighter weight. The weight of the entire car is about 40 kg. MYNUCAR4’s design is more focused on the body surface that is large enough to fit six solar panels on it.
Team UKM – Fuel Cell
Kencana has many advantages that enable for our team to achieve success in Sepang. One of the advantages of Kencana is the aerodynamic body design and light weight allows Kencana to move faster thus saving more energy. Besides, the cells that were used is zero emission fuel cell where there is no harmful gaseous release such as carbon dioxide. The motor used to move Kencana is mounted directly on the wheel. Lastly, the handling system used are based on go kart handling system enable Kencana be easily controlled to avoid the accident happened on the day of the competition later.
Team UKM - LPG
Under the hood of the blazing red and white exterior with black detailing, a prominent feature of the MYNUCAR 2 is its usage of liquefied petroleum gas, or LPG as fuel. LPG is a low-carbon-emitting fuel that consists of a flammable mixture of propane and butane. It is synthesized by refining petroleum, and is derived from fossil fuel sources extracted from oil or gas streams that emerge from the ground. It has a calorific value of 94 MJ/m3, and can be mixed with air to produce synthetic natural gas (SNG) which easily substitutes natural gas, which has a calorific value of 38 MJ/m3. The LPG evaporates at normal temperatures and pressures, and is usually stored in pressurized steel cylinders. The advantages of using LPG are many. Firstly, it is an efficient fuel, because it has a higher net calorific value, 46000 kJ/kg compared to an equivalent amount of diesel, which has a net calorific value of 42600 kJ/kg and petrol, 42900 kJ/kg. This allows it to burn more cleanly and completely, making it an environmentally friendly fuel alternative.
LPG is a commonly used fuel alternative to gasoline and diesel in highly developed countries like the United States, United Kingdom, Europe, Australia, and in some Asian countries, namely Thailand. It has yet to exude significant presence in the Malaysian automotive industry, most likely due to the abundance petroleum, lack of necessity for change and weak market for alternative fuels. By integrating simplicity in design, confidence in the performance of new fuel alternatives and a steadfast principle towards the conservation of the environment, MYNUCAR 2 is an embodiment of not only man and machine, but also of nature.
