In recent years, the interests on transient operation and real driving emissions have
increased because of the global concern about environmental pollution that has led to new …

In recent decades, the importance of emerging alternative fuels has increased significantly
as a solution to the problems of global warming and air pollution from energy production. In …

Oxy-fuel combustion concept is studied in a compression ignition engine (CIE) using Mixed
Ionic-electronic Conducting Membranes (MIECs) to separate oxygen (O 2) from air in order …

The oxy-fuel combustion engine concept with onboard oxygen generation and carbon
capture (CC) is studied using as a starting point a baseline oxy-fuel combustion layout …

The possibility of applying oxy-fuel combustion to a compression ignition engine (CIE) at
different operating points regarding engine speed and load is studied in this work. To do so …

Sustainable and efficient refrigerants are essential due to increasing regulatory constraints
on traditional high-GWP refrigerants. This study investigates the potential of natural …

Several investigations related to increasing engine thermal efficiency focusing on the engine
hydraulic circuits (oil and coolant) were performed over the last years. According to …

The global push to reduce greenhouse gas emissions has led to the ban of high global
warming potential (GWP) refrigerants in the refrigeration sector, prompting the adoption of …

Due to the need to achieve a fast warm-up of the after-treatment system in order to fulfill the
pollutant emission regulations, a growing interest has arisen to adopt variable valve timing …

This study uses an optimization approach for developing a combustion system in a
compression–ignition engine that is able to operate under oxy-fuel conditions, and produces …
