Improving thermal efficiency and reducing carbon emissions are the permanent themes for
internal combustion (IC) engines. In the past decades, various advanced strategies have …

In spark ignition engines, knock onset limits the maximum spark advance. An inaccurate
identification of this limit penalises the fuel conversion efficiency. Thus it is very important to …

Water injection in highly boosted gasoline direct injection (GDI) engines has become an
attractive area over the last few years as a way of increasing efficiency, enhancing …

Artificial Intelligence is becoming very important and useful in several scientific fields.
Machine learning methods, such as neural networks and decision trees, are often proposed …

This work is focused on the development and validation of a spark advance controller,
based on a piston “damage” model and a predictive knock model. The algorithm represents …

The further thermal efficiency improvement of marine natural gas engine is constrained by a
knocking phenomenon that commonly occurs in gas-fueled spark-ignited engines. It plays …

Knocking combustions heavily limits the efficiency of Spark Ignition engines. The
compression ratio is limited in the design stage of the engine development, letting to Spark …

Both spark ignition (SI) natural gas engines and compression ignition (CI) dual fuel (DF)
engines suffer from knocking when the unburnt mixture ignites spontaneously prior to the …

Nowadays Spark Ignition (SI) engine developments focus on downsizing, in order to
increase the engine load level and consequently its efficiency. As a side effect, knock …

Traditional processing of knock signals reduces each recorded time history to a single scalar
knock intensity metric for each engine firing, thereby losing all information relating to the …
