Due to the high cost, the popularization of this technology is restricted. In the future, as the technology further matures, costs may also fall.
There is a clear sensory gap between Volkswagen's hybrid products and Toyota's hybrids. Although it has a good direct-injection turbine engine, Volkswagen's hybrid technology performance is not as good as Toyota's. The fundamental reason is still the technical patent issue. The technology in this area is in the hands of Japanese companies, or in the hands of Honda, Toyota, and Denso. If you want to get the right to use the corresponding technology, you must be as sincere as Toyota when purchasing German companies.
When the mixed injection system is under low load conditions, the manifold injector injects fuel during the intake stroke of the cylinder, the mixture enters the cylinder, and then the injector in the cylinder injects fuel during the compression stroke, thereby Achieve stratified combustion.
Under high load conditions, the mixed injection system will only perform direct injection in the cylinder during the compression stroke. In this way, it can not only improve the working efficiency of the engine, but also avoid the emission problems caused by excessive oxygen under low load conditions in engines with only in-cylinder direct injection technology.
