A new technology that can be applied to automobiles is a matter of course that all automobile companies want to obtain, but it is confusing if the only purpose of obtaining it is to lock it in a safe. What kind of technology is this?
The caption at the end gives the answer—catalytic exhaust purification system. The main function of this modern car’s equipment is to purify car exhaust. The key is “catalysis”, which uses catalysts to purify the exhaust The harmful substances are converted into harmless gases such as nitrogen, carbon dioxide, and water vapor. It stands to reason that this technology is beneficial to humans without any harm. Automobile companies should rush to adopt it. But why does the situation in the film appear?
The film colluded with various auto companies to conceal the scientific and technological achievements for 15 years without explanation. We can explore it based on the principle of the catalytic exhaust purification system. Catalytic exhaust gas purifier has a fatal shortcoming. It can only be applied to cars with unleaded gasoline as fuel. Because leaded gasoline is used, the lead in the exhaust gas will cover the catalyst, making the purifier stop working. Any effect. The prerequisite for the use of catalytic exhaust gas purifiers in automobiles is to use unleaded gasoline. At this point, the big boss appeared.
Leaded gasoline is considered one of the worst inventions of the 20th century. Before 1923, there was no gasoline in gasoline, and there was almost no lead in the earth's atmosphere. All these changes are due to the idea of a "smart" person. It is the American chemist Thomas Midgley Mailer (ThomasMidgleyJr). The engine is the "heart" of the car. This frequent "premature beats" has brought about a decrease in power, an increase in fuel consumption and mechanical damage. "Knock" has become a major problem that plagues the automotive industry. In 1921, a young Mickley who was working at General Motors in the United States discovered that gasoline added with tetraethyl lead compound can improve the operating efficiency of car engines and can also remove the car’s cata-crash sound. This discovery has brought huge economic benefits to the company, and tetraethyl lead has been hailed as a "gift of God" for a while. In 1923, General Motors, DuPont and Mobil Petroleum Company of New Jersey set up a joint venture called Tetraethyl Lead Gasoline Company (referred to as "SiB Company"), which specializes in the production of tetraethyl lead compounds. The product was quickly promoted all over the world. The elimination of "knock" has also brought about a surge in car sales, making the United States a "country on wheels" more quickly. As a result, a continuous flow of lead in the exhaust pipe of a car is mixed with exhaust gas and discharged into the atmosphere, causing great harm to human health. Many scientists have conducted research on this, but it is not easy to talk about. In the past half century, every research on the impact of lead in the United States has been funded by the manufacturers of lead additives. Four B companies continue to declare: Lead is non-toxic and harmless. Until influence in the 20th century is known as the greatest geologist Clair Cameron Patterson ( to calculate the age of the earth man ) under the joint efforts of the leader and the led many scientists medical workers, in 1970 the US Environmental Protection The bureau issued the Air Cleaner Act and began to make regulations on motor vehicle exhaust emissions. The environmental policy of phasing out leaded gasoline was determined in 1973, and tetraethyl lead was gradually abolished in 1975.
In such a big environment change, the technology that has been kept secret in the safe finally sees the light of day. Greedy people took money that they shouldn't have, and the result was either a dead end or nothing, while the greedy capital did evil but retreated. The power of capital is so terrifying. In the face of such a BOSS, all ordinary people can do is No Sudden Move.
