To maximize engine performance most important factor is to maintain engine temperature such as:

• • Optimize engine temperature by using nano technology particles that have magnetic properties has higher thermal conductivity than any other material.
• • Heat conduction also affect engine performance the better heat distribution the more engine power.
• • Circulation of cooling water

It is known that colloid material containing Nano particles that have magnetic properties has higher thermal conductivity than any other material. Nano-fluid is based on the principle that when a small amount of Nano particles are injected into regular fluid, such as water or oil, the fluid comes to have much higher thermal conductivity. Theories on Nano-fluid have been proven by researching every year and the application of Nano-fluid technology is increasing. In addition to cooling devices for electronic part, Nano-fluid is used widely for high efficiency heat exchange devices, such as heat exchange system, refrigerators and automobile engines.

When the cluster of water particles is small, the area that contacts the engine increases, thus the speed of heat absorption increases and the cooling efficiency of engine increases. The action mechanism of Car-vita is based on its role as catalyst that induces complete combustion and optimizes cooling of engine by activating ions in the coolant in the automobile and turning it into Nano-fluid.
