In recent years, global warming and air pollution have become more and more serious, which are caused by oil and other traditional fuels. Therefore, seeking clean energy without pollution has become an urgent problem to be solved. Recently, alcohol-free vegetable oil fuel technology has appeared, which has the advantages of low temperature combustion, cleanliness and non-toxicity. Alcohol-free vegetable oil fuel is very suitable as a fuel to replace petroleum fuel because of its low combustion temperature. In addition, its engine performance is much better than traditional fuel. Because there is no hydrocarbon in alcohol-free vegetable oil fuel, it has lower gasoline leakage, which is also an incomparable advantage of traditional fuel. The formula of alcohol-free vegetable oil fuel technology includes different kinds of vegetable oils, such as palm oil, sesame oil, flax oil, cycad oil and so on. , as well as vitamins and vitamin A, which can make the fat and lecithin in plants swell, making it easier for them to produce methane gas. In addition, the technical formula of alcohol-free vegetable oil fuel also includes different silicone oil and polymer materials, such as rubber, PVC, PVC fiber, polypropylene, etc., which can improve the performance of fuel and make it cleaner and safer to use. In addition, atypical additives, such as calcium chloride, aluminum hydroxide, calcium hydroxide, etc. , can be added to make the fuel cleaner, help protect the engine and combustion chamber, and prevent carbon deposition. The technical formula of alcohol-free vegetable oil fuel can solve air pollution and energy crisis, and it is an important part of clean energy development in the future. It can not only improve energy efficiency, but also help reduce greenhouse gas emissions, thus making our society greener.
