Beijing Fuel Quality Upgrading Automotive Direct Injection Engine Welcomes Spring

At the end of May, Phase V of vehicle gasoline and diesel standards implemented at the end of May adjusted the No. 93 and No. 97 gasoline to No. 92 and No. 95, and the price was temporarily unchanged. Some car owners worry that reducing the gasoline label means that the quality of gasoline is lower than before. On the contrary, this measure is an upgrade to the fuel standard. The aim is to reduce vehicle pollutant emissions through oil upgrading: Adjusted gasoline reduces the sulfur content limit from 50 mg/kg to 10 mg/kg, and the manganese limit to 0.002 g/L to 0.002 g/L. L. At the same time, in order to prevent insufficient combustion due to low vapor pressure, the lower limit value of vapor pressure indicators for gasoline is increased. The winter and summer vapor pressure limits are 45 to 85 kPa and 42 to 65 kPa, respectively. The changes in the refining process have adjusted the indicators such as the density and kinematic viscosity of automotive diesel.

So what impact does this new gasoline and diesel standard have on consumers? First of all, it should be stated that the improvement of fuel quality does not necessarily mean that fuel consumption can be reduced, but it can definitely reduce the amount of exhaust gas emitted by vehicles, thereby reducing the impact of vehicle emissions on the environment. In addition, since Beijing Gasoline has become “fine grain” in the future, the direct-injection technology models that were once deterred by the lack of gasoline quality may have regained the attention of consumers.

Direct injection technology, by definition, is the engine technology that injects fuel directly into the cylinder. Compared with the traditional engines, the direct injection technology makes the combustion of gasoline more complete, the power output is more powerful, but also reduces fuel consumption and exhaust emissions, and is one of the engine technologies that are currently widely used in Europe and the United States. However, due to the restriction of oil quality in the country, the brand of direct-injection engines is still a minority. The representative models of direct injection technology on the market today include Volkswagen's Magotan and Passat, as well as Buick's LaCrosse and Regal. The strong output from Volkswagen's TSI direct-injection turbocharging technology has always been its strength, and the DSG tiptronic gearbox has helped improve performance, in addition to having good fuel economy. Buick's 2.4L and 3.0LSI DI smart direct injection engines and the powerful 2.0TSIDI smart direct injection turbocharged engine also provide high power, low fuel consumption, and low emissions. Imagine that in the near future, with the gradual improvement of fuel quality in Beijing and even in the whole country, we can completely shake off the concerns about the quality of oil products. Then the engines with direct injection technology and more advanced technologies may be able to get bigger. The scope of the exhibition space.
