Shayyish Engine is different from all existing engines which are fuel-functioned that consume considerable energy. While Shayyish Engine operates without the need for external energy or fuel and is operated manually or by another engine, then the engine operates independently without the need for any external energy or fuel, contrary to the currently existing engines which stop working when the fuel or energy run out. Shayyish Engine is a gearbox, which is different from the usual gearbox which gives less speed with greater torque or greater speed with less torque, where Shayyish Engine has a totally different way of work, where it can produce torque greater than initial torque with rotational speed greater than initial rotational speed, therefore, we can connect both ends of movement axes (initial movement axes with final movement axes) by toothed levers make the movement permanent with both very high and surplus torque and speed. Shayyish Engine can be fastened to cars, trains, planes, ships, stations of electricity generation, all kinds of devices, from the biggest ones to the mobile charger, all that has to do with energy, and all depending on size and ability. Shayyish Engine can be manufactured from different materials have solidarity and strength depending on the necessity and the amount of torque and speed required.
