Biomass-burning organic-aerosol (OA) emissions are known to exhibit semi-volatile
behavior that impacts OA loading during plume transport. Because such semi-volatile …

We assessed the gaseous, particulate, and genotoxic pollutants from two current technology
gasoline direct injection vehicles when tested in their original configuration and with a …

To ensure reliable starting under cold weather conditions (< 0° C ambient), gasoline
engines use fuel enrichment, leading to higher soot formation and greater tailpipe particle …

We assessed the physical, chemical and toxicological characteristics of particulate
emissions from four light-duty gasoline direct injection vehicles when operated over the …

This paper presents a model-free reinforcement learning approach for optimal speed control
of gasoline engines. First, the physics of the controlled internal combustion engines are …

A comprehensive study on the effects of photochemical aging on exhaust emissions from a
vehicle equipped with a gasoline direct injection engine when operated over seven different …

The effects of the length of the gas flow path from the exhaust outlet in the cylinder head to
the catalyst inlet in the exhaust line, the ignition timing and the engine idle speed on the …

This paper presents a model-based control scheme to the cold-start speed control in spark
ignition (SI) engines. The multi-variable control algorithm is developed with the purpose of …

The combustion characteristics in the first cycle are very important for all kinds of spark
ignition engines, regardless of port fuel injection (PFI) or direct injection spark ignition (DISI) …

The first firing cycle is very important during cold-start for all types of spark ignition engines.
In addition, the combustion characteristics of the first firing cycle affect combustion and …
