economic function of profits and losses The importance of gasoline was not recognized in the 19th century, when it was used in a great deal of kerosene. The oil refining then relied on simple distillation processes to separate the different components of the oil from the boiling point. The boiling point of the kerosene component is higher, and the use of safety when lighting lamps becomes the main product of crude oil refining, while gasoline and other components are often burned as fuel. By the mid - to late 19th century, the successful use of gasoline engines in 1886, in 1886, the gasoline engine was successfully used as a driving force, thus the importance of gasoline increased. But using distillation, only 20% of the gasoline can be extracted from crude oil. In 1911, the standard oil company have solved the problem of low gasoline yield, by William burton and Robert hamm forest thermal cracking process of the invention, the heavy quality heating gas oil cracking of light gasoline fractions, such as to overall improve the gasoline yield, thermal cracking process in 1913 won the patent license in the United States. The subsequent catalytic cracking process has further improved the gasoline yield and octane value. , BMO capital markets of U.S. rates strategy director Ian Lygen is described: "we believe that prices change due to interest rate debt investors don't want to stand in front of a sell-off on the eve of the end of catch a falling knife." Cylinder work volume refers to the volume of gas swept by the piston from the top to the bottom, also known as single cylinder displacement, depending on the cylinder diameter and the piston stroke. Engine displacement is the total volume of working volume of each cylinder, usually expressed in milliliter (CC). Engine displacement is one of the most important structural parameters. It is more representative of engine size than cylinder diameter and cylinder number, and many indicators of engine are closely related to displacement. Financial staff are used to dividing the investment payback period into long-term, intermediate and short-term periods.
