(Non-wind powered) Self-Propelled Vehicles

Introduction A self-propelled vehicle is one that does not need man or animal power to run. Every modern vehicle now falls under this category, with the most notable one being the automobile.
An automobile is a wheeled motor vehicle used for transporting passengers, which also carries its own engine or motor [1]. Many of the denominations for automobiles include motor car, auto car, or car. Numerous dictionaries and sources that define the word automobile, state that they run on an internal-combustion engine. While this is true, not all automobiles run on gasoline or petroleum. The electric car and steam engines have shown that many alternatives exist to power vehicles. Dictionaries also

Austrian inventor Siegfried Marcus soon resolved this when he effectively installed a liquid-fuelled inner combustion engine on a plain handcart in 1870, which makes him the first man to thrust a vehicle using gasoline.
These breakthroughs in the development of engines later led to the invention of other types of vehicles which include: the airplane, the submarine, the helicopter, and modern ships.

Scientific explanations
Steam engines
Heat and water are indispensable ingredients to make a steam engine function. Water is heated inside a boiler, which turns it into steam. Steam engines and motors usually have a “chimney” to draw out the gases generated from the heat, depending on what exactly is heating the water but if it is fire, then this is essential. The boiler usually contains two large tubes at the top of it that collect the steam and relocate it to the steam chest and cylinders. Once there is sufficient pressure generated, the steam passes from the primary steam pipe to the cylinders. The steam then obliges the piston to move which then turns a wheel, mechanism, gear, or turbine. At the end of the stroke the steam goes in through the other end and the piston shifts the opposite way, ousting the exhaust.
Combustion Engines All internal combustion engines rely on the combustion of a chemical fuel. This process normally outcomes in the production of a large quantity of
