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.
