Si engines still kicking
Written by Allesandro Ferrari and Pietro Pizzo, a
new SAE International book covers spark-ignition
engines from their birth to the present day. Its title is
Injection Technologies and Mixture Formation
Strategies For Spark-Ignition and Dual-Fuel Engines.
Gasoline engines had dominated the market of

passenger cars from the beginning of the automobile
history until the 1990s. In the mid-1980s, the
introduction of electronic controls for injection
timing and delivered fuel mass as well as the
application of turbocharging led to the opportunity
of using direct injection diesel engines in passenger
cars.
The introduction of common-rail technology in the
Fuel injection systems and performance is fundamental to combustion
engine performance in terms of power, noise, efficiency, and exhaust
emissions. There is a move toward electric vehicles (EVs) to reduce
carbon emissions, but this is unlikely to be a rapid transition, in part due
to EV batteries: their size, cost, longevity, and charging capabilities as
well as the scarcity of materials to produce them. Until these isssues
are resolved, refining the spark-ignited engine is necessary address
both sustainability and
demand for af fordable
and reliable mobility. Even
under policies oriented to
smart sustainable mobility,
spark- igni ted engines
remain strategic, because
they can be applied to
hybridized EVs or can
be fueled with gasoline
blended with bioethanol or
bio-butanol to drastically
reduce particulate matter
emissions of direct injection
engines in addition to lower
CO2 emissions.

is an accurate review
of spark-ignited engine
fuel injection systems,
which have represented
a key technology in the
development of the
gasoline engines during
the last decades. "

In Fuel Inject Systems, Alessandro Ferrari and Pietro Pizzo provide a full
review of spark-ignited engine fuel injection systems. The most popular
typologies of fuel injection systems are considered, with special focus
on state-of-the-art solutions. Dedicated sections on the methods for air
mass evaluation, fuel delivery low-pressure modules, and the specific
subsystems for idle, cold start, and warm-up control are also included.
The authors pay special attention to mixture formation strategies, as
they are a fundamental theme for SI engines. An exhaustive overview of
fuel injection technologies is provided, and mixture formation strategies
for spark ignited combustion engines are considered. Fuel Injection
Systems illustrates the performance of these systems and will also serve
as a reference for engineers who are active in the aftermarket, offering
detailed information on fuel injection system solutions that are mounted
in older vehicles.

late-1990s gave a decisive impulse to the
penetration of direct injection diesel engines with
increased specific power within the automotive
market. Diesel share in total passenger cars
progressively increased during the 2000s in Europe,
South Korea, India, South America, and Australia,
whereas North America, China, Japan, and Russia
remained overwhelmingly gasoline markets.
In particular, the European community supported
diesel engine development by maintaining separate
emissions standards, with less severe targets than
those for gasoline engines. During the early-2010s,
diesel engine passenger cars sold in Europe were
able to overcome those fueled with gasoline. The
diesel engine became the primary resource to satisfy
the progressively stringent fleet-wide targets on
CO2 for passenger cars, established as mandatory
regulation in Europe since 2009.

engineers professionally because it provides an

updated and exhaustive
overview about fuel injection
technologies and mixture
formation strategies for sparkignited
combustion engines. It
offers a full illustration of the
performance of these systems
and of the engines, in which
they are installed, and detailed
technical data pertaining to the
different injection components.
The book could also represent a
reference for engineers that are
active in the aftermarket
because it is generally difficult
to obtain detailed scientific
information on fuel injection
system solutions that are still
mounted in older vehicles. n
