“…It is suggested that engine oil is pressed past the sealing ring (oil squeezing) due to vibration movements of the turbocharger shaft. Increased wear can favour the mentioned transport processes over the engine operational life [7,10,11].…”

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.

<div class="section abstract"><div class="htmlview paragraph">Hydrogen internal combustion engines are a robust and cost-efficient solution to decarbonize the heavy- duty on- and off-highway vehicle sectors. Mature base technology, low additional system costs, and no dependence on expensive raw materials will enable a fast market penetration and thus a rapid reduction of CO2 emissions, provided customer expectations for performance, driving range and total cost of ownership as well as regulatory requirements such as ultra-low pollutant emissions can be met.</div><div class="htmlview paragraph">The power density of a hydrogen engine is currently limited by uncontrolled combustion events such as knocking, pre-ignition and backfiring. Tenneco, TME and FEV show in this paper how the optimization of components and combustion strategies minimizes these risks such that Diesel-like performance can be reached.</div></div>
