Rapid depletion of conventional fossil fuels and increasing environmental concern are
demanding an urgent carry out for research to find an alternate fuel which meets the fuel …

Spark ignition gasoline vehicles comprise most light duty vehicles worldwide. These
vehicles were not historically associated with PM emissions. This changed about 15 years …

Modern spark ignition engines mostly use one injection system to deliver gasoline into the
combustion chamber, using either direct injection or port fuel injection. Both technologies …

The particulate matter (PM) emissions of gasoline vehicles were much lower than those of
diesel vehicles until the introduction of diesel particulate filters (DPFs) in the early 2000s. At …

Octane rating is an essential property for gasoline-type fuels because it is the major factor
that determines the maximum compression ratio (CR) allowed in spark-ignition engines. In …

Energy crises and environmental issues require the development of green fuels for engines.
Isopropanol is an excellent performance renewable alternative fuel for SI engines. It can be …

The DPF regeneration is crucial for reducing backpressure, minimizing negative impacts on
engine power and fuel economy, but the changes in particulate emission characteristics it …

This paper aimed to study the effects of water injection and spark timing on performance of a
hybrid hydrogen-gasoline engine. For this aim, a modified four-cylinder turbocharged …

Flash boiling can enhance fuel breakup and atomization via the quick growth and eruption
of bubbles when the high temperature fuel exiting the nozzle. For multi-hole fuel injectors, a …

The uneven temperature field, flow field, and internal low temperature of the catalytic
converter can cause substrate thermal deformation and catalytic ability decrease, which is …
