International trade knowledge base

* Title: The International trade knowledge baselatest automotive power solution of diesel engine manufacturers With the increasing global attention to environmental protection, automobile manufacturers are also paying more and more attention to the development and release of the latest automotive power solutions. Its green environmental protection performance. Among them, diesel engines, as one of the most widely used sources of power, have been further improved in terms of technical level and performance after some negative reports and adjustments, and have become qualified green environmental protection power. Diesel deliveryThe latest automotive power solutions of motivation manufacturers have made great progress in technology and environmental protection performance, allowing us to gain an in-depth understanding of its connotation. I. Technological innovation With the progress of science and technology, diesel engine manufacturers have made many attempts and innovations in technology. Traditional diesel engines have been greatly updated, mainly manifested in the following aspects: 1. The third-generation high-pressure common rail technology is adopted to greatly improve the pressure of fuel injection, so that the fuel can burn better and achieve low emissions and high efficiency. Two. Equipped with an efficient EGR (exhaust gas recycling) system, the engine exhaust gas can be reused, reducing exhaust emissions, and greatly reducing NOx emissions. 3. The use of DPF (diesel particle filter) can filter out the particles generated by the combustion of the diesel engine and greatly reduce its particle emissions.Four. And the unique SCR technology, when driving at medium and high speeds, the NOx substance produced after intake heating and combustion is absorbed and transformed by the urea liquefaction substance sprayed by the SCR nozzle. After conversion, only water and nitrogen enter the exhaust gas emission system, reducing the emission of nitrogen oxides by nearly 90%. 5. Intelligent low-noise technology, the application of technology to alleviate the noise caused by redundant airflow during the engine transition, and by introducing an intelligent control system to optimize the speed and emission of the engine, the overall noise reduction effect of the engine is more significant. II. Better environmental protection performance. In addition to technological innovation, the latest automotive power solutions of diesel engine manufacturers have also made great progress in environmental protection performance. The environmental protection performance of the new diesel engine is mainly reflected in the following aspects: 1. Less exhaust emissions: Adopt DPF particle filter and SCR technology to greatly reduce particulate matter and NOx in the exhaust gas. Because the urea solution needs to be transformed through a unique SCR technology, this method is relatively simple, has a wider range of improvement, and can be widely promoted in the industry. The emission standards of this low-emission engine are relatively high. Its emission standards mainly involve the four exhaust emission limits of NOx, CO, PM and HC. Among them, NOx emissions are the most critical one and are also the specific reasons for the restart of diesel engines by brands such as Audi, Porsche and BMW. Two. Lower fuel consumption: The fuel consumption rate of diesel engines is lower. With the continuous improvement of technology, the fuel consumption rate of diesel engines will be further reduced. 3. Greater contribution to the environment: the new diesel engine not only exhaustsIt has superior performance in terms of discharge and fuel consumption, and can also parasitize on electronic cars. If the driving conditions of the electronic control car and the emission exceed the standard, it will issue a warning sound. III. Wider scope of application. Due to the emergence of new diesel engines, the shortcomings of traditional diesel engines have been gradually improved, and the market for diesel engines has been opened up again. Because diesel vehicles are superior to gasoline vehicles in terms of natural loss of fuel, fuel quality, comfort and flexibility, diesel engines have a wider range of applications. For example, in Europe, the sales of diesel engines account for more than half of the entire automobile market. The efforts of diesel engine manufacturers in environmental protection and technological innovation have enabled new diesel engines to enter the market, and in the gradual large-scale promotion, this not only revives diesel technology, but also provides more effective choices for the wider market and consumers.
