Engine production: Engine manufacturers launch new products to improve fuel efficiency. With people's increasing attention to environmental protection and UEFA live freeenergy saving, the fuel efficiency of automobile engines has also become a key factor for car owners when buying cars. In order to meet market demand, automobile engine manufacturers are also constantly developing and launching new products to improve the fuel efficiency of engines. At present, many engine manufacturers on the market have launched a variety of high-efficiency engines, which can maximize fuel efficiency in addition to achieving higher power output. Next, let's take a look at the characteristics and advantages of these engines. 1. Hybrid-based engines. Engines based on hybrid technology are an important trend in the field of automobile engines at present.This engine consists of a power system and a fuel system, which realizes the coordination of the two systems through intelligent control, thus improving the fuel efficiency of the engine. Engine manufacturers such as Toyota, Honda and Ford have launched many high-efficiency engines, including hybrid power, which can increase fuel efficiency to more than 30%. Two. Turbocharged engine Turbocharged engine is an engine with a turbocharged device, which increases the intake pressure by adding a turbocharger to the intake duct, thus improving the power output and fuel efficiency of the engine. At present, most car manufacturers have used turbocharged engines in their models to achieve more efficient fuel consumption and improve the driving experience of the vehicle. 3.Direct injection engine Direct injection engine can effectively improve fuel efficiency, because in this engine, the fuel is directly injected into the cylinder for combustion, instead of flowing through the valve. This kind of engine can use fuel more efficiently, thus improving fuel efficiency. Automakers such as Audi and BMW have begun to use direct injection engines in their vehicles. Some studies show that direct injection engines can increase fuel efficiency by about 15%. Four. Variable speed and start-stop system The automatic start-stop system can help the vehicle turn off the engine in the parked state and start it again when the vehicle restarts. In addition, the design of the gearbox and the use of the variable valve timing system can also improve the fuel efficiency of the car engine. These improvements can help car manufacturers improve fuel efficiency by 10% to 15%. In shortAutomobile engine manufacturers are actively developing various high-efficiency engines. The purpose of these engines is to improve fuel efficiency as much as possible while reducing the impact on the environment. Although these high-efficiency engines usually require higher costs, they do provide owners with lower fuel consumption and a better driving experience. Therefore, with the development of technology, we can expect more high-efficiency engines to appear in the future and inject more vitality into the automobile industry.
