to provide the same air fl ow characteristics ( Fig. 2.190 ). Early engines, with
manifolds using pipes of differing lengths, often produced slightly different
combustion patterns in each of the cylinders.
At the entrance to the inlet manifold is the throttle body controlling the fl ow and
quantity of air entering the engine.
On most engines, the temperature of the incoming air supply is controlled.
Heating the air entering the inlet duct assists in atomization and fuel distribution
