Manufacturers and government agencies set their own "pure electric timetables". For example, luxury brand Bentley's model lineup will be adjusted to include only plug-in hybrids and electric vehicles by 2026, and all models will be electrified by 2030. In October, California Governor Gavin Newsom issued an executive order directing the state to stop selling gas-powered vehicles in the new car market by 2035. For a naturally aspirated engine, its power output increases linearly as your speed increases, so there will be no sudden power nodes.
Moreover, engines with larger displacements in the middle and rear sections accelerate faster, which means that the popular engine is not necessarily the best. Unless the cabin has very high power requirements and cannot accommodate a naturally aspirated engine, a supercharged engine will be more harmful than a naturally aspirated engine. Supercharged engines are a product of policy. Large-displacement naturally aspirated engines are far superior to small-displacement turbocharged engines in terms of driving quality and power performance. However, due to the restrictions of environmental protection laws and the impact of rising oil prices, they were gradually replaced by turbocharged engines, and even naturally aspirated engines have been adhered to.
Different from traditional manifold injection, direct injection (GDI) installs the fuel nozzle in the cylinder and injects fuel directly into the cylinder to mix with the intake air. The injection pressure is further increased, making the fuel atomization more detailed. At the same time, the special design of the nozzle position, spray shape, air intake flow control and piston top shape allows oil and gas to be fully and evenly mixed in the entire cylinder, resulting in higher energy conversion efficiency, improving engine efficiency and fuel economy. As early as the 1950s-1970s, in-cylinder direct injection technology already existed, but was ultimately shelved due to immature electronic control technology, high cost, and substandard nitrogen oxide emissions.
Today, with the improvement of the technical capabilities of car companies and the promotion of fuel consumption standards and regulations, vehicles equipped with in-cylinder direct injection engines are becoming more and more common in the market. Industry insiders pointed out that in the next three to five years, car companies will basically adopt this technology. For some electric car enthusiasts, this is undoubtedly another bold move to combat climate change, but it also leads to the problem that impure electric cars will still be with us in the next 10-15 years. While scaling up electric vehicles, improving the vehicle's fuel economy as much as possible remains an industry priority.
