Knock is an abnormal and stochastic combustion phenomenon which limits the efficiency of
spark ignition engines. It occurs because of autoignition initiated locally in hot spots in the …

Knock combustion is one of the primary factors limiting thermal efficiency improvement in
spark ignition (SI) engines. After a century of research, scholars have made significant …

Of late there has been a resurgence in studies investigating parameters that quantify
combustion knock in both standardized platforms and modern spark-ignition engines …

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 automotive industry is experiencing radical changes under the pressure of institutions
that are increasingly reducing the limits on CO< sub> 2 and pollutant emissions from road …

Knock in spark ignition engines is stochastic in nature. It is caused by autoignition in hot
spots in the unburned end-gas ahead of the expanding flame front. Knock onset in an …

In this work an exhaust gas temperature and a piston damage model are coupled, with the
aim to develop an innovative model-based strategy for the calibration of the lambda map …

Downsized turbocharged engines have been increasingly popular in modern light-duty
vehicles due to their fuel efficiency benefits. However, high power density in such engines is …

The objective of this work is to analyze the signal of a piezoelectric washer installed under
the spark plug and to compare the combustion metrics evaluated with such signal to the …

Certain oxygenated compounds, when blended with gasoline, have the ability to inhibit the
occurrence and decrease the intensity of engine knock, helping improve engine efficiency …
