The development of modern automotive engines in environmental protection technology is reflected in multiple aspects, and the following are some key environmental protection technologies:
1. CVVD technology (continuously variable valve duration technology):
The CVVD technology developed by Hyundai Motor is a groundbreaking engine technology that optimizes the ratio of the mixture in the combustion chamber by adjusting the opening time and lift amount of the valves in real time, thereby improving combustion efficiency. This technology not only improves fuel economy and reduces harmful emissions, but also ensures the power performance and response speed of vehicles at various speeds.
2. Hydrogen fuel cell technology:
Modern cars have also made significant progress in the field of hydrogen fuel cell vehicles. For example, the NEXO model is equipped with Hyundai's fourth generation fuel cell technology, which uses hydrogen and oxygen in the air to undergo an electrochemical reaction to generate electricity to drive the engine. The final emissions are only water, purifying the air up to 99.9%. In addition, the hydrogen fuel cell heavy-duty truck XCIENT Fuel Cell has strong power and environmental performance, equipped with a 180kW hydrogen fuel cell system consisting of two 90kW hydrogen fuel cell stacks, which improves durability and overall fuel efficiency of the vehicle.
3. Hybrid technology:
The hybrid technology of modern cars combines the advantages of internal combustion engines and electric motors, improves fuel efficiency and reduces emissions by optimizing the power system adaptation. For example, the hydrogen hybrid sports car concept car Vision FK combines a hydrogen fuel cell energy converter with a high-power rear wheel drive plug-in PE power system, providing a high-performance and environmentally friendly driving experience.
4. High efficiency combustion system and electrification of accessories:
Modern automobiles have achieved a maximum thermal efficiency of over 45% for a hybrid engine with a combustion equivalence ratio of 1.5T by integrating and innovating technologies such as high-efficiency combustion systems, electrification of accessories, and intelligent control, which is at the international leading level.
5. Application of environmentally friendly materials and energy-saving technologies:
Modern cars actively adopt environmentally friendly materials and energy-saving technologies in their products to reduce carbon footprint and improve energy efficiency. For example, the standard booth at the exhibition has fully adopted E0 grade panels to ensure recyclability and compliance with fire safety standards; Replace traditional building materials with reusable materials such as profiles and Kabu spray painting.
The development and application of these technologies demonstrate the efforts and achievements of modern automobiles in reducing environmental pollution and improving energy efficiency, while also reflecting the global trend of environmental protection technology in the automotive industry.
