Fuel is supplied from the fuel rail (2) to each cylinder via
electronically controlled fuel injectors (1), mounted to the
intake manifold (3) runners.
Air flow into the intake manifold is metered with a throttle
body assembly (4), which is fastened and sealed to the
intake manifold. The throttle body is controlled and
monitored by the ECM to adjust fuel/air mixtures.

Exhaust gases are expelled through the exhaust side of
the cylinder head into the exhaust manifold (5), which is
fastened and sealed to the cylinder head. Exhaust gases
are monitored with the oxygen sensor (6), which provides
the ECM with data to adjust fuel/air mixtures. The entire
exhaust manifold is surrounded by a heat shield (7) to aid
in prevention of accidental burns.
