Hydrogen generated from renewable sources is an eco-friendly fuel that can be used in automotive industry or for energy generation purposes. Hydrogen is a high-energy content gas and its carbonless chemical structure can provide significant benefits of high thermal efficiency and near zero or very low carbon emissions when combusted with other fuels.

In this study, the implementation of hydrogen fuel was tested at low and medium operating loads in a heavy-duty hydrogen-diesel dual-fuel engine. The paper provides a detailed experimental analysis of the effects of hydrogen energy share ratio and various combustion strategies such as exhaust gas recirculation, diesel injection pressure and diesel injection patterns.

At low load conditions, engine operation with an H₂ energy share ratio of up to 98% was achieved without any engine operation implications. This condition provided a simultaneous reduction of carbon and NOx emission of over 90% while soot emissions were dropped by 85% compared to the conventional diesel-only operation. At medium load, the increased NOx emission due to the high energy content of hydrogen fuel was found to be the primary challenge.

由可再生资源产生的氢气是一种环保燃料，可用于汽车工业或用于发电。氢气是一种高能量含量的气体，其无碳化学结构可提供显着的好处，即与其他燃料燃烧时具有很高的热效率以及接近零或非常低的碳排放量。

在这项研究中，在重型氢柴油双燃料发动机的中低运行负荷下测试了氢燃料的实施。本文对氢能份额比和各种燃烧策略（例如废气再循环，柴油喷射压力和柴油喷射方式）的影响进行了详细的实验分析。

在低负载条件下，实现了H ₂能量份额比高达98％的发动机运行，而没有任何发动机运行隐患。与传统的纯柴油操作相比，此条件可同时减少90％以上的碳和NOx排放，而烟尘排放却减少了85％。在中等负荷下，由于氢燃料的高能量含量而增加的NOx排放被认为是主要挑战。
