Design of a test stand for a diesel engine powered by hydrogen, dedicated to HDV vehicles
The aim of this study was to design a test stand enabling experimental research on the feasibility of using hydrogen in heavy-duty vehicles, and to evaluate its impact on exhaust emissions, noise levels, and engine performance. The first part of the paper presents a literature review on the historical and contemporary use of internal combustion engines. An analysis of alternative fuels was also conducted, with classification based on international standards, along with a discussion of various hydrogen production methods. The subsequent section describes the complex process of converting a diesel compression-ignition engine into a spark-ignition engine fueled by a hydrogen–air mixture. This part of the study outlines the key components of the SW680 engine, which serves as the core of the proposed test stand. Emphasis is placed on the necessary modifications to engine subsystems, as well as the development of new systems for fueling, ignition, and control. The final chapter presents the design of individual components of the test stand, including the base structure, engine mounting frame, and selection of test and measurement equipment. Safety requirements for both the stand and its surroundings are also addressed, including references to specific solutions such as a ventilation system equipped with hydrogen detectors and the selection of an appropriate fuel tank.
