What Are The Precautions When Using Diesel Engines?

Aug 03, 2021

It is caused by the lack of technical level, rather than the intrinsic problem of diesel engines, which can be solved through technological progress.

First of all, all kinds of power have their proper positions and timing for their development. It is lagging not to start research and development of new technologies such as gas-fuel vehicles, hybrid vehicles, electric vehicles, and fuel cell vehicles. However, it is wrong to one-sidedly emphasize the possibility of large-scale promotion in the short-term, and it is even contrary to the normal development of conventional power. Secondly, gas fuel engines should be evaluated in two. Although gas-fueled engines can better meet the current emission requirements, it is of great significance to the adjustment of energy utilization structure, but the total amount of hydrocarbons (mainly methane) emitted by natural gas engines is higher than that of diesel, which is meeting the Euro IV emission standards. There will also be many difficulties. Third, emissions and energy conservation are equally important, and the two should be considered comprehensively. Energy conservation is not only a saving of petroleum resources, but also an important environmental protection issue. Take the current international concern about the global greenhouse effect as an example. Diesel engines have low fuel consumption and carbon dioxide emissions are much lower than gasoline engines, which can reduce greenhouse gas emissions by more than 45%.

1. Key component technologies: such as oil pump nozzles and supercharged and intercooled technology.

2. Fuel quality: high-quality, low-sulfur diesel is a prerequisite for diesel engines to meet increasingly stringent emission regulations.

3. Electronic control technology: Diesel electronic control technology is essential for the optimization and improvement of the overall performance of the engine.

4. Key technologies for post-emission treatment: such as exhaust gas recirculation (EG R) technology, particulate capture technology, and NO x catalytic conversion technology.

5. Complete engine development and matching technology: such as matching and optimization technology for diesel fuel, intake and combustion systems, and diesel engine technology for heavy vehicles and cars.

6. Diesel engine manufacturing, process and material technology.
