An air bulk change engine is provided to produce large power with low energy in a small space by using characteristics of air. An air bulk change engine includes a crank shaft(10), a coupling unit(11), a bearing(12), a support(13), a supporting bar(19), a cylindrical large cylinder(20), a piston(30), a connecting rod(31), a fixing bolt(32), a gear box(40), a rotational shaft(41), and an electric generator(50). The crank shaft rotates by power of the connecting rod. The coupling unit couples the crank shaft with the connecting rod. The bearing is installed at the support and holds the crank shaft. The supporting bar is installed on the support and fixes the cylinder. The piston reciprocates according to change of the volume of air inside the cylinder. The connecting rod transmits power of the crank shaft. The gear box converts rotary power of the crank shaft into a proper rotational frequency. The electric generator generates electricity by receiving power from the rotational shaft.
