[DiBryce]

Here is a detailed introduction to the advantages and disadvantages of a DVVT engine: 1. Advantages: The DVVT engine features advanced technology that reduces intake and exhaust overlap, ensuring stable combustion; it minimizes intake loss, improves combustion efficiency, enhances fuel economy, and saves on fuel costs. DVVT technology can better regulate the air-fuel mixture ratio, reduce the generation of nitrogen oxides, and make emissions more environmentally friendly. 2. Disadvantages: Since DVVT is a relatively advanced technology, its drawbacks include high manufacturing difficulty, elevated production costs, and higher maintenance and repair expenses in the long run.
