PRINCIPLES GASOLINE/DIESEL FUEL SYSTEMS - OD1620 - LESSON 1/TASK 2
(c) The temperature sensor will at times bleed off only a portion
of vacuum, causing the damper door to remain between the hot and cold
position. This will regulate the temperature by providing a blend of hot
and cold air.
(d) Whenever the engine is heavily accelerated, the manifold
vacuum will drop and the damper door will move to the fresh air intake
position.

Conclusion
This task covered the principles, construction and function of gasoline fuel
systems, and completes lesson one. In lesson two, the function and
construction of diesel fuel systems will be covered beginning with a
discussion on the characteristics of diesel fuel. Before proceeding to
lesson two, however, test your knowledge of lesson one by completing the
practical exercise that follows.
