The light hybrid vehicle also has obvious problems, that is, the price is high, and the reliability of its power system is also affected because of the integration of fuel and electric technology models. In fact, the technical upgrading of fuel engines is carried out simultaneously with the electrification technology of automobiles. There is no obvious difference between excellent fuel engines and light-mixed vehicles in terms of fuel consumption and other indicators, but the cost is lower.
The CVVD technology of Hyundai Kia Motors is the latest example of the continuous improvement of fuel engine technology. At present, this technology has registered more than 100 patents in China, the United States, the European Union and other countries and regions. It breaks through the bottleneck and limitation of engine variable valve control technology so far and is regarded as an epoch-making technology. Hyundai-Kia Motors' profound accumulation in engine technology has been verified again.
The CVVD of Hyundai Kia Motors refers to the technology of continuously variable valve duration. Different types of engines have different performance and fuel efficiency because of different intake and exhaust valve control methods. Therefore, valve control technology is the core of engine technology, and it is constantly evolving under the impetus of major manufacturers. Porsche developed variable valve timing technology for the first time in the world; The appearance of variable valve lift technology is attributed to BMW, and CVVD technology is pioneered by Hyundai Kia Motors in the world, and its essence lies in the free control of valve opening and closing time. The engine adopting CVVD technology can improve the overall performance by 4%, fuel efficiency by 5% and exhaust emission by 12%, which is a real "black technology" in the field of automobile engines.
The emergence of CVVD technology is a milestone in the history of human automobile engines, and the biggest benefit to customers is the "double drop" of travel costs and car purchase costs. The improvement of fuel efficiency can significantly reduce fuel consumption. Kia Motors said that the fuel consumption of the 1.5T engine with CVVD technology is only 5.7L per 100 kilometers. This fuel consumption level can be easily achieved by many light-mixed vehicles, but hybrid vehicles reduce fuel consumption by reducing displacement and increasing motors. Additional costs need to be paid by users, and CVVD technology will not lead to a sharp increase in car prices. The appearance of CVVD technology proves that fuel vehicles are far from leaving the historical stage, which is enough to make people forget hybrid vehicles.
