MAKE THE POINT: Power Stroke Turbocharging Basics
Turbocharger
A turbocharger (or turbo for
short) uses the engine‘s exhaust
gases to spin a turbine, which
in turn drives a compressor to
force more air into the engine.
Increasing the airflow allows
more power to be generated.
A turbo consumes very little
power under light loads or easy
engine use and allows smaller
engines to generate the power
of a larger displacement. When
extra power is needed, the turbo
spins into action.
Turbo Lag
This is the time it takes for the
turbocharger to spin after the driver
steps on the accelerator. This delay
can be caused by the turbo having to
wait for the exhaust gas to spin the
turbine and drive the compressor.
Anotherfactorinlagisthesizeofthe
turbo. Bigger turbos make more power,
but take longer to respond. In the past,
the typical solution was to use two
smaller turbos for faster response.
However, this approach added the
cost and complexity of two turbos,
and generated twice the heat.
The Innovative
Power Stroke Approach
The 6.7L Power Stroke uses a single-
sequential turbocharger design.
Instead of two separate turbos, a
single-sequential turbo places two
compressors back-to-back on a
common shaft in a single housing.
The Power Stroke Benefit
This design allows the system to
have a response time similar to a
twin-turbo package, while reducing
cost, weight, complexity and
underhood heat.
