『CarUp』is the remarkable item to realize reduction of fuel consumption and reduction of the exhaust gas (CO & HC), by putting it into the coolant reserve tank for the radiator. 『CarUp』 is of the cylindrical shape made of stainless steel which contains the patented BioGlass balls. BioGlass is the safe and non-hazardous glass which is made of the natural mineral ores. Among the items to help the improvement of the fuel consumption, there are of the materials which radiate the radioactivity, however, BioGlass does not radiate radioactivity. 『CarUp』put into the coolant reserve tank of the radiator ionizes the coolant to the negative as the temperature of the coolant rises while driving. The negative ions surrounding the engine housing will act to the inside of the engine through the radiator coolant. With this action, the fuel increases its combustion speed and maintains the perfect combustion conditions, which leads the fuel consumption improved.
