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.
The choice between the original car parts and replacements
As you know, the original car parts can sometimes be very expensive, especially if we think about replacing parts in the car with the high-end class. Many people are looking for savings decides to invest in a used auto parts or replacements. Whether in this case the higher the price of a higher quality product and whether deciding on a replacement for a mistake? It actually depends on the individual case. Sometimes it may be that the replacement is just as valuable as the original part, and it is not necessary to install the original to the efficient operation of our car. However, there are also cases in which the replacement is very fast operation due to the lower quality of the product and must again replace the part.
Wikipedia about organic type of oil
Organic oils are produced in remarkable diversity by plants, animals, and other organisms through natural metabolic processes. Lipid is the scientific term for the fatty acids, steroids and similar chemicals often found in the oils produced by living things, while oil refers to an overall mixture of chemicals. Organic oils may also contain chemicals other than lipids, including proteins, waxes (class of compounds with oil-like properties that are solid at common temperatures) and alkaloids.
Lipids can be classified by the way that they are made by an organism, their chemical structure and their limited solubility in water compared to oils. They have a high carbon and hydrogen content and are considerably lacking in oxygen compared to other organic compounds and minerals; they tend to be relatively nonpolar molecules, but may include both polar and nonpolar regions as in the case of phospholipids and steroids.
