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 …

Large-bore natural gas reciprocating generator engines will play crucial roles in future low-
carbon energy systems. Knock, as an abnormal combustion phenomenon, is a bottleneck for …

Knock is one of the main limitations on increasing spark-ignition (SI) engine efficiency. This
has been known for at least 100 years, and it is still the case today. Knock occurs when …

This paper presented an experimental and numerical study of pre-chamber volume, number
of orifices and orifice diameter influence on engine performance and emissions. All the …

ABSTRACT A correlation was developed to predict the ignition delay of PRF blends at a
wide range of engine-relevant operating conditions. Constant volume simulations were …

In experimental calibration of mass production spark-ignition (SI) engines, knocking cycles
are usually determined by a specified threshold of knock intensity (KI). In engine cycle …

Modern spark-ignited (SI) engines offer excellent emission reduction when operated with a
stoichiometric mixture and a three-way catalytic converter. A challenge with stoichiometric …

The numerical analysis of performance of a four cylinder highly boosted spark-ignition
engine at full load is described in this paper, with the research focused on introducing high …

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 …

Due to the ever increasingly stringent emission regula-tions for passenger vehicles, the
efficiency and performance increase of Spark Ignition (SI) engines have been under the …
