How to Predict The Future Trend of Diesel Engine Technology?

From the perspective of diesel engines, there are two or three major trends.
Trend one
Better fuel economy, continuous reduction of carbon dioxide emissions to improve fuel efficiency, better use of waste heat, reduction of peroxide emissions, and lighter weight, these are major trends that will not change, but emissions regulations will be even more strict. The internal combustion engine cycle always produces waste, so it needs to work in other areas. This is a big trend.

From Cummins‘ point of view, we produce a lot of parts, such as fuel system, booster system, control system, filter, aftertreatment system, we invest a lot in these aspects, and always provide customers with high-efficiency fuel to meet stringent emission standards. engine.

Trend two
People have higher expectations for California standards, they will require NOx emissions to continue to decrease, and the next standard under discussion and negotiation will be more challenging and will be much lower than current standard emission limits, when national standards are There will be controversy, so every manufacturer is making technical reserves for this, but the trend is still unclear.

Cummins is currently conducting a forward-looking project to use existing energy sources to develop next-generation diesel engines with the goal of increasing fuel efficiency to 50% from truck aerodynamics, tires and engines, which will be significant Improvement. I think Cummins is leading this trend, breaking through new technologies, allowing customers to work more efficiently and reduce costs.

Trend three
How to apply new technologies such as electrification in heavy trucks. Because in the field of heavy trucks, it is difficult for batteries to replace the engine as the main power unit, but like hybrids, there is such a potential, so there will be a lot of work to be done in this area. So what can an electric car do, or what other help can be provided by electrification, such as a heater in a thermal management system, or a battery can help solve some of the problems in the cycle or use some of the braking energy, but on long distances In transportation, there is less braking, so less energy can be collected, so in order to improve fuel economy, we need other technical characteristics.
