The main pollutants of diesel automobile exhaust are: carbon monoxide, nitrogen oxides, hydrocarbons, lead, sulfide and so on. Their pollution to the environment is mainly manifested in greenhouse effect, ozone layer destruction, acid rain, black rain and other phenomena. The harm to human body is mainly manifested in causing various diseases, seriously damaging the respiratory system and having strong carcinogenicity. Harmful substances emitted by cars while driving harm the environment and human health. These harmful substances are very complex, mainly including carbon monoxide, nitrogen oxides, hydrocarbons and so on. Carbon monoxide is the product of incomplete combustion of fuel in the engine, and its binding force with human hemoglobin is far stronger than oxygen and hemoglobin.

According to the way that diesel automobile exhaust enters the body, up to 60% of the total lead intake can remain in the human body permanently, and adult blood mixed with more than 0.8mg is called lead poisoning. Clean the three-way catalytic converter regularly to maintain the purification performance of motor vehicle exhaust. Popularize natural gas-fueled gas vehicles and transform them to solve the problems such as the decline of engine power performance and the large space occupied by gas cylinders. Strengthen the publicity of the importance of environmental protection, raise people's awareness of environmental protection, let people consciously use public transport, do not buy cars with substandard exhaust emissions, and resolutely do not buy or manufacture leaded and low-quality gasoline.

"Jienengbao" diesel purifier is a special equipment for purifying diesel oil. Its unique integrated multi-stage filtration technology can filter out more than 90% harmful impurities (including colloid and asphaltene in diesel oil), and it has strong oil-water separation function. It can ensure the cleanliness of diesel oil to the maximum extent, thus protecting the engine, reducing wear and tear, prolonging the service life of the engine, improving fuel utilization, reducing fuel consumption and improving exhaust emissions! The scientific name of automobile urea is diesel exhaust treatment liquid. Which is applied to diesel engines. It is a liquid used in SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. Its components are 32.5% high purity urea and 67.5% deionized water.
