Modifications of a spark ignition engine to operate with hydrogen and methane blends

Abstract

An investigation project is carrying out with the aim to analyze deeply the performance of spark ignition engines fuelled with hydrogen and methane blends in the widest range of operation conditions. This project comprises two phases. This paper is focused to the first one, which expose the selection of engines to achieve the aim of the investigation project, the modifications and sensorization that engines require for hydrogen and methane blends and testing and the gaseous fuel supply line implemented in the testing bench under the most strict safety and efficiency conditions according to technical specifications of installations and equipment for hydrogen.
