oil for Hummer Agricultural machinery, construction
The most popular when it comes to automotive, enjoy, of course, cars and motorcycles. With the increasing number of drivers also increases the number of such vehicles on our roads. However, in everyday life may be useful also other machines connected to the most popular vehicles. A good example can be here the equipment needed in agriculture, which is often not independent of the vehicle. Many agricultural machines and used in the construction industry we can associate, for example, a tractor suitable brand, which will certainly be of interest holders of such a vehicle. Of course, there is also a lot of self-propelled agricultural machines, but they are often very expensive.
engine - wikipedia
An engine or motor is a machine designed to convert one form of energy into mechanical energy.12 Heat engines, including internal combustion engines and external combustion engines (such as steam engines), burn a fuel to create heat, which then creates a force. Electric motors convert electrical energy into mechanical motion; pneumatic motors use compressed air and others?such as clockwork motors in wind-up toys?use elastic energy. In biological systems, molecular motors, like myosins in muscles, use chemical energy to create forces and eventually motion.

History of car
The first working steam-powered vehicle was designed?and most likely built?by Ferdinand Verbiest, a Flemish member of a Jesuit mission in China around 1672. It was a 65-cm-long scale-model toy for the Chinese Emperor that was unable to carry a driver or a passenger.72122 It is not known if Verbiest's model was ever built.22
Cugnot's 1771 fardier ? vapeur, as preserved at the Musée des Arts et Métiers, Paris
Nicolas-Joseph Cugnot is widely credited with building the first full-scale, self-propelled mechanical vehicle or car in about 1769; he created a steam-powered tricycle.23 He also constructed two steam tractors for the French Army, one of which is preserved in the French National Conservatory of Arts and Crafts.24 His inventions were, however, handicapped by problems with water supply and maintaining steam pressure.24 In 1801, Richard Trevithick built and demonstrated his Puffing Devil road locomotive, believed by many to be the first demonstration of a steam-powered road vehicle. It was unable to maintain sufficient steam pressure for long periods, and was of little practical use.
The development of external combustion engines is detailed as part of the history of the car, but often treated separately from the development of true cars. A variety of steam-powered road vehicles were used during the first part of the 19th century, including steam cars, steam buses, phaetons, and steam rollers. Sentiment against them led to the Locomotive Acts of 1865.
