PRINCIPLES GASOLINE/DIESEL FUEL SYSTEMS - OD1620 - LESSON 2/TASK 1
cause a pressure differential that increases proportionally with viscosity
that, in turn, will cause the piston to seek a position in its bore that
becomes higher as viscosity increases.
(4) The upward movement of the servo piston will move a wedge-shaped
movable plate which will increase fuel delivery.
A lower viscosity fuel
will cause the piston to move downward causing the pump to decrease fuel
delivery.
3.
Conclusion
This task described the characteristics of diesel fuel.
Having gained an
understanding of diesel fuel, our attention in the next task will focus on
the function and construction of diesel fuel systems.
