A V6 internal combustion engine from a Mercedes car
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.
How do you get your car repaired?
Defects or minor failures occur in every car, and this is due to its operation. It would seem that the older the car, the more trouble, however, and the latest models can sometimes give bone its owner. In such a situation, there is nothing else to look for a mechanic who not only repair the vehicle, but the occasion does not demand for the service a lot of money. The cost will depend on how large the scope of work will need to be carried out and whether it is necessary to buy spare parts. Surely every driver wants to give up your car in the best possible hands, so it is worth looking mechanics guided by the opinion of customers who have already benefited from its services and are happy with the result.
On September 6, 1866 American John Ellis founded the Continuous Oil Refining Company (Later to become Valvoline). While studying the possible healing powers of crude oil, Dr. Ellis was disappointed to find no real medicinal value, but was intrigued by its potential lubricating properties. He eventually abandoned the medical practice to devote his time to the development of an all-petroleum, high viscosity lubricant for steam engines ? then using inefficient combinations of petroleum and animal and vegetable fats. He made his breakthrough when he developed an oil that worked effectively in high temperatures. This meant no more gummed valves, corroded cylinders or leaking seals. In 1873 Ellis officially renamed the company to Valvoline after the steam engine valves the product lubricated.
