Description

Energy-saving and environment-friendly method and energy-saving and environment-friendly equipment available for internal combustion engine

Technical Field

The invention relates to the field of internal combustion engines, in particular to an energy-saving and environment-friendly method and energy-saving and environment-friendly equipment for an internal combustion engine.

Background

Along with the development of human activities, the energy required by human beings is more and more scarce, and the pollution of human beings to the environment is more and more serious. Especially in big cities, as automobiles gradually enter households and automobiles on streets are more and more, the exhaust emission of the automobiles becomes an important environmental pollution source. In addition, due to the large consumption of limited energy resources on earth, the price of fuel is increasing, and an internal combustion engine with low oil consumption and low pollution discharge is increasingly required as a power source for various vehicles or other fixed equipment. It is important to control the combustion of an internal combustion engine to reduce the fuel consumption of the internal combustion engine and to simultaneously purify the exhaust emissions of harmful substances. In the prior art, various modes such as (1) oil additives, (2) magnetized oil, (3) ignition voltage enhancement, (4) harmful substance catalysis, (5) tail gas recovery secondary combustion, (6) electronic injection, (7) engine production precision improvement and the like are adopted to achieve the purposes of oil saving and environmental protection, and certain effect is achieved. However, the existing technologies have more or less various defects. Such as: (1) The electronic injection effect is best, but (1) the cost is too high, and common vehicles or equipment are difficult to bear; (2) it is only applicable to internal combustion engines fueled by gasoline. (2) improving the production precision of the engine: has extremely high requirements on production technology and production equipment and is difficult to reach the standard. (3) tail gas recycling: the cost of the modification is too high. (4) oil additives: the effect is unclear, neither stable nor obvious. (5) magnetizing oil: the ignition point of the oil is reduced, the oil is easy to ignite, and the oil has little effect on energy conservation and environmental protection. (6), boosting the ignition voltage: the ignition safety factor is enhanced, the fuel is prevented from being discharged without being ignited, and the energy-saving and environment-friendly effects are small. (7), catalytic harmful substances: the energy loss is increased while the environmental protection is realized at the cost of sacrificing a part of power. The method has various advantages in energy conservation and environmental protection, but neglects a most basic problem, namely that combustion and explosion of combustible mixed gas need a large amount of oxygen to support combustion when the internal combustion engine works. The conventional internal combustion engine is far from satisfying the demand for oxygen during the operation of the internal combustion engine because the oxygen content in the combustible mixture of the internal combustion engine is supplied by 21% of the oxygen contained in the naturally aspirated air. Therefore, the internal combustion engine works in an oxygen-deficient state, and the fuel cannot be fully combusted, so that the energy conversion rate (availability) of the fuel is very low, and the fuel consumption is increased. In fact, the turbocharging device and the method for increasing the number of the valves are both used for increasing the air suction amount, but the essence is to increase the oxygen intake amount. But the negative effect of doing so is: because the proportion of oxygen in the air is fixed, the consequence of increasing the amount of oxygen by increasing the amount of air intake is that other 79% of the air is increased in proportion to the amount of air intake of the gas which is not beneficial for the blasting operation, and the gas which is not usable in the air is subjected to the chemical combination action of high temperature and high pressure in the combustion chamber, so that a large amount of carbon monoxide, nitrogen oxides, hydrocarbons and other harmful substances which pollute the environment are inevitably generated and discharged in the tail gas, and the discharge capacity of waste gas is greatly increased. The result is energy savings, but increased emissions, which are not reimbursed.

The purpose of the invention is: on the premise of not changing the working principle and structure of the existing internal combustion engine, the energy-saving environment-friendly method which can increase the oxygen supply amount to ensure that combustible mixed gas can be fully and completely combusted in a combustion chamber and can reduce the discharge amount of harmful substances in tail gas under the condition of not influencing power is provided for the internal combustion engine.
