Like most of the developed countries, France's car market also belongs to the mature market, tend to be saturated, most new car sales are no longer a first-time buyers of consumer is bought, is more of a used car. Subject to regional economy, the cost of living, and the influence of cultural background, etc, the French are more keen to sta domestic car, in French, so we will find that their vehicle seems to is not match with the national economic development level, and it is precisely the characteristics of these European developed countries have in common, they did not imagine the high to the requirement of cars, more practical. Psa Peugeot Citroen sold 51,188 cars in France in 2014, down 2.2% from a year earlier, according to data from the auto industry. Sales at Renault also fell 0.4 per cent year on year to 37,898 units. In addition, Volkswagen, ford, Toyota and most other car companies suffered declines in France in 2014, and France's current car market is not expected to sell well. Security is very important, reduce risk is big potential! 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. Loading is the work load that is allocated to a work centre. For example, time might be lost while changing over from making one ingredient of another. If the machine in time breaks down, it will not be available. If there is machine reliability data available, this also needs to be taken into account. Sometimes the equipment could possibly be awaiting parts to reach or be 'idling' for a few other reason. Other losses could include an allowance for the device being run below its optimum speed as well as an allowance for that 'quality losses' or defects which the machine may produce. Of course, many of these losses must be small or non-existent in a well-managed operation. Finite loading is definitely an approach which only allocates work to a work up to and including set limit. This limit will be the estimate of capacity to the work centre (based on the times designed for loading). Infinite loading is surely an method of loading work which does not limit accepting work, but rather tries to cope with it. Until then, depositors had not even seen a rise. In November 2017, Advisor Perspectives published an article said that in addition to the improvement of fuel efficiency, petrol consumption decline is due in large part to the following factors: the ageing staff away from the workplace; The home office model is developing more and more; Social media takes the place of face-to-face communication, and travel is unnecessary. More and more young people are no longer driving their cars. And urban population growth accelerated, reducing per capita gasoline dependence.
