SPOTLIGHT ON FUEL EFFICIENCY
Powering green performance
Delphi helps vehicle makers make smaller, lighter, more efficient engines
that enable greater fuel efficiency and lower emissions, without sacrificing
performance — because “fun to drive” is the essence of the driving
experience. Today’s leading vehicle makers employ many strategies to deliver
more fuel efficient performance, beginning with the type of fuel — gasoline,
diesel, natural gas — and the various injection technologies that enable
burning fuel as efficiently as possible. We embrace them all.
In gasoline systems, we’re at the forefront of GDi (gasoline direct
injection) systems and valve train solutions that deliver precise
amounts of air to the combustion chambers with sophistication and
control. In diesel, our award-winning common rail systems are found in
the best automobiles and commercial vehicles, delivering the benefits
of quieter operation, reduced emissions and better performance. With
natural gas, a fuel that naturally burns cleaner, we are active in every
kind of application, from dual-fuel systems combined with either gas
or diesel to engines that run entirely on natural gas.
The industry has come a long way since emissions regulation began
in the mid 1970s. Toxic emissions, such as carbon monoxide and
nitrous oxide, are down as much as 99% since then. Incremental
progress is still being made with toxic emissions, but the focus has
shifted to reducing CO2 emissions — the carbon footprint of vehicles.
That means fuel efficiency is paramount, and that’s what we deliver.
Down the road, we see significant developments in applying the
advantages of gasoline combustion to diesel and vice versa — bringing
low cost emissions control to diesel and free-breathing efficiency
to gas engines. A new gas combustion technology, gasoline direct
injection compression ignition or GDCI, allows unthrottled operation
without excessive NOx production. In diesel, stoichiometric
combustion promises much more complete, low emission combustion.
We are ready.
