Abstract(E)	Carbon-neutral mobility has become the focus of all highly regulated markets and currently proposed regulations favor battery-electric powertrains solutions. In markets and application use cases, however, where the supply of electricity is limited and fast charging infrastructure is still under development, alternative solutions will be needed for the foreseeable future. Here, Diesel engines will remain a robust and reliable technology, offering improvement potential by using the latest engine technology and an advanced fuel injection system to achieve an indicated efficiency of almost 50%. Key is the enhancement of cylinder peak firing pressure up to 300 bar in combination with the latest nozzle technology for optimal mixing formation. Furthermore, adding a serial-hybrid powertrain offers the potential of significant fuel saving, which results in CO₂ reduction of up to 20% for off-highway applications. Such topology uses advanced cooling solutions, due to the amount of power generation and depletion. In addition to CO₂ saving, the future Diesel engine needs to comply with the next generation of emission legislation. For commercial vehicles, these are given by the European EUVII and the US C.A.R.B. low-NOx regulation program. To achieve the published limits, a combination of different technologies for the engine and the aftertreatment system are required. The proposed paper will present these technology solutions and their impact on CO₂ and emissions by means of engine testing and simulation.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
