Abstract

Disclosed herein are a uniform pressure unequal surface engine and an engine for power generators using the same. The uniform pressure unequal surface engine includes a kernel cylinder having a fuel supply unit. A kernel piston is airtightly provided in the kernel cylinder and reciprocated by explosive force when fuel is burnt, thus providing rotating force to a rotating shaft. A pressure reducing cylinder is connected to the kernel cylinder via an openable exhaust gas pipe, has a relatively larger inner diameter than the kernel cylinder, and has no fuel supply unit. A pressure reducing piston has a relatively larger outer diameter so as to have a larger contact area with exhaust gas compared to the kernel piston, reciprocates in the pressure reducing cylinder while remaining airtight, and obtains power by acting with greater exhaust gas pressure on the pressure reducing piston because the pressure reducing piston has an area of contact with exhaust gas larger than that of the kernel piston when the exhaust gas pipe is opened. An air compressor inputs compressed air into the kernel cylinder when exhaust is being conducted from the kernel cylinder to the pressure reducing cylinder, thus pushing exhaust gas from the kernel cylinder into the pressure reducing cylinder, and providing new compressed air into the kernel cylinder.
