CHEMICAL-FREE ENGINE USING SPRING, CAPABLE OF GENERATING KINETIC ENERGY IN RESTORING WITH POTENTIAL ENERGY ACCUMULATED IN COMPRESSING OR EXTENDING A SPRING AND CONVERTING KINETIC ENERGY INTO LINEAR MOTION AND ROTATION WITH A PISTON AND A CRANKSHAFT

摘要

PURPOSE: A chemical-free engine using a spring is provided to prevent environmental pollution, and to reduce cost by generating kinetic energy in restoring with potential energy accumulated in compressing or extending a spring and converting kinetic energy into linear motion and rotation with a piston and a crankshaft. CONSTITUTION: An engine comprises a linear motion unit(200) having a spring(260) radiating internal potential energy accumulated in compressing or extending into kinetic energy in restoring, and a linear motion frame(240) containing the spring and linearly reciprocating up and down in expanding or contracting the spring; a rotation unit(300) having a crankshaft(320) including a first crank(322) rotating by receiving linear motion of the linear motion frame in the lower part of the linear motion unit and a second crank(324) transmitting rotation to the linear motion frame, a power transmission gear(340) attached to the end of the crankshaft to output rotational force of the crankshaft, and a flywheel(360) rotating actively and continuously; a motion transmission unit(400) having a chain train(410) and a first connecting rod(420) rotating the crankshaft by converting linear motion of the linear motion frame into rotation to the first crank, and a hydraulic unit(430) and a second connecting rod(490) converting rotation of the second crank into linear motion to the linear motion frame; and an auxiliary unit(500) having a starting motor(520) starting the engine by rotating the flywheel, a generator(540) generating electricity by using rotational force of the crankshaft, and a charging battery(550) accumulating the electricity.
