Precautions for using diesel engine

First of all, various dynamics have their due position and timing for development. Not starting to research and develop new technologies such as gas fuel vehicles, hybrid vehicles, electric vehicles and fuel cell vehicles would be falling behind. However, it is wrong to unilaterally emphasize the possibility of large-scale promotion in the short term, or even to oppose the normal development of conventional power. Secondly, gas fuel engines should be evaluated in two parts. Although gas fuel engines can better meet current emission requirements and are of great significance to the adjustment of energy utilization structure, the total amount of hydrocarbons (mainly methane) emitted by natural gas engines is higher than that of diesel. In order to meet the Euro IV emission standards There will also be many difficulties encountered. Third, emissions and energy conservation are equally important, and both should be considered comprehensively. Energy conservation is not only about saving oil resources, but also an important environmental issue. Taking the current international concern about the global greenhouse effect as an example, diesel engines have low fuel consumption and much lower carbon dioxide emissions than gasoline engines, and can reduce greenhouse gas emissions by more than 45%.
1. Key component technologies: such as oil pump nozzle and supercharged intercooling technology.
2. Fuel quality: High-quality, low-sulfur diesel is the prerequisite for diesel engines to meet increasingly stringent emission regulations.
3. Electronic control technology: Diesel engine electronic control technology is crucial to the optimization and improvement of overall engine performance.
4. Key emissions post-treatment technologies: such as exhaust gas recirculation (EGR) technology, particulate capture technology and NOx catalytic conversion technology.
5. Whole machine development and matching technology: such as matching and optimization technology for diesel engine fuel, air intake and combustion systems, and diesel engine technology for heavy-duty vehicles and cars.
6. Diesel engine manufacturing, technology and materials technology.
