motor and engineNote that if there isn’t any combustion, there is no engine. Purely electric automobiles don’t have engines. An engine is a motor that converts thermal vitality to mechanical work. A motor is a machine that converts other types of energy into mechanical vitality and so imparts movement.

Medium-dimension motors of highly standardized dimensions and characteristics provide handy mechanical power for industrial makes use of. The very largest electrical motors are used for propulsion of enormous ships, and for such purposes as pipeline compressors, with rankings in the hundreds of kilowatts. Electric motors may be categorized by the supply of electric energy, by their inside construction, and by their software. The largest internal combustion engine ever constructed is the Wärtsilä-Sulzer RTA96-C, a 14-cylinder, 2-stroke turbocharged diesel engine that was designed to energy the Emma Mærsk, the biggest container ship on the planet when launched in 2006. This engine has a mass of 2,300 tonnes, and when operating at 102 RPM (1.7 Hz) produces over 80 MW, and can use up to 250 tonnes of gas per day.

Some had been quite complex, with aqueducts, dams, and sluices to keep up and channel the water, along with systems of gears, or toothed-wheels manufactured from wooden and steel to manage the pace of rotation. More subtle small devices, such as the Antikythera Mechanism used complex trains of gears and dials to act as calendars or predict astronomical occasions. In a poem by Ausonius within the 4th century AD, he mentions a stone-cutting noticed … Read More
