Development of a method to investigate the influence of engine oil and its additives on combustion anomalies in hydrogen engines

Abstract

To counteract the anticipated consequences of climate change, significant efforts are required across all industries. The use of hydrogen in internal combustion engines can make a valuable contribution as a carbon-neutral bridging technology. One challenge in developing a suitable combustion process is the high ignition propensity of hydrogen, impacting combustion stability due to combustion anomalies. Avoiding such combustion phenomena is of utmost relevance to ensure a long-term stable engine operation. Oil entry into the combustion chamber can impact the occurrence of combustion anomalies. Therefore, a specific method for controlled oil entry into the combustion chamber has been developed, and this method is detailed in the following article.
