TRANSPORTATION DEVICE AND POWER SYSTEM THEREOF
A power system suitable for use in a transportation device is provided. The power system includes an engine, a gas tank and a gas pipe. The engine has at least a gas cylinder with a piston. The gas tank is used for storing a high pressure noninflammable gas. The gas pipe is connected to the engine and the gas tank. The high pressure noninflammable gas is delivered into the cylinder via the gas pipe to drive the piston so as to drive and move the transportation device. Therefore the transportation device of the present invention can replace the transportation device which uses fuel as the power source.
1 . A power system, suitable for use in a transportation device, the power system comprising:
an engine, comprising at least a cylinder having a piston;
a gas tank, for storing a high pressure gas, wherein the high pressure gas is noninflammable; and
a gas pipe, connected to the engine and the gas tank, for delivering the high pressure gas to the cylinder of the engine.
2 . The power system according to claim 1 , wherein the gas pipe comprises a switch valve, and when the switch valve is turned on, the high pressure gas enters the cylinder and when the switch valve is turned off, entry of the high pressure gas to the cylinder is stopped.
3 . The power system according to claim 1 , wherein the gas pipe comprises a throttle valve disposed between the engine and the gas pipe.
4 . The power system according to claim 2 , wherein the engine comprises a plurality of cylinders, and each of the cylinders is connected to the gas pipe, and the gas pipe comprises a switching valve disposed between the cylinders and the switch valve.
5 . The power system according to claim 1 , wherein the gas tank stores a liquefied gas including liquid nitrogen or liquid helium.
6 . The power system according to claim 1 , wherein the high pressure gas comprises high pressure air, high pressure helium or high pressure nitrogen.
7 . The power system according to claim 1 , wherein the gas tank comprises a check valve, and the high pressure gas enters the gas tank via the check valve.
8 . The power system according to claim 7 , wherein an end of the check valve is connected to an air compressor for filling the high pressure gas from the air compressor to the gas tank for storage.
