It will be necessary to slightly modify the engine to burn individual fuels, but the basis should be the same.

Cummins, one of the major producers of internal combustion engines, has also begun working in recent years on solutions for zero-emission or low-emission transportation. However, in addition to the development of electrification, it does not depreciate traditional combustion engines, for which it has several alternative solutions in reserve.
In the past, the company mentioned that it was working on the development of a new pure hydrogen internal combustion engine. A few days ago, however, it reportedly introduced the first fuel-agnostic (independent or universal) internal combustion engine in its industrial sector, which should become a universal solution for decarbonizing current fleets using low-emission fuels.

It is not a universal engine into which almost anything could be poured, but rather a platform that uses the same engine blocks and key components. Common components should be located from the engine head gasket down, while the upper part of the engine uses slightly different components – adapted to the specific type of alternative fuel.
The company plans to apply this new design approach to its established B, L and X series engines, which will learn to burn alternative diesel, natural gas and hydrogen. The most universal engine will be the B6.7 unit, which should be able to burn clean diesel, natural gas, petrol, propane and hydrogen. However, it will always be an adjustment to only one type of fuel.

According to the company’s representatives, the new approach to the design and development of low-emission internal combustion engines should meet the unique demand in the transportation industry and at the same time benefit from a similar product architecture. The similarity of the components should facilitate the manufacture and service, the training of staff or the installation of engines burning different fuels in the same chassis.
The company also believes the new engine will make it easier for it to reduce greenhouse gas emissions and help improve the environmental impact of the transportation industry. Cummins also plans to achieve zero emissions, but by 2050.
