Abstract:

The concept of a hydrogen diesel with direct gaseous hydrogen injection, despite the obvious dvantages as compared to a traditional diesel, is poorly explored. In this article, the problem of the determination of the rotational charge motion intensity value in a hydrogen diesel cylinder is first formulated and solved in order to establish the limits for the heat loads on the main parts (on a piston) of a motor under the hydrogen combustion. 3D Mathematical modeling of local non-stationary heat transfer in the combustion chamber was performed for the experimental single-cylinder hydrogen diesel MAN 24/30.

Keywords: hydrogen diesel, direct injection, 3D-mathematical model, local heat transfer, piston.
