SENSORS
Air Flow Sensor (Incorporating Atmospheric Pressure
Sensor)
To reduce pressure losses and thus improve performance,
Mitsubishi Motors developed a new air flow sensor known
as MUKAS. In contrast with a conventional sensor, which
senses Kármán vortices downstream of a vortex-inducing pillar
using a pressure-sensitive element, the MUKAS sensor counts
Kármán vortices in a bypass passage using a hot-wire arrangement.
Pressure losses
reduced by 50%
Size and weight
reduced by 20%
Improved resistance
to contamination and
noise
Increased sensitivity at low air flow
rates enables the use of a larger air
inlet. Thus, pressure losses are reduced.
A more condensed circuit layout
and a new, compact connector enable a significant reduction in overall length.
Only a small amount of air flows
through the bypass passage, so
contamination is greatly reduced.
Also, Kármán vortices are mea-
sured digitally in accordance with
the difference in signals received
from left and right hot-wire arrangements, so the sensor is resistant to
noise and to changes in the components that occur over time.

ACTUATORS
Secondary Air Control Solenoid Valve
The secondary air control valve is an ON/OFF solenoid valve.
It switches the pressure applied to the secondary air valve
between the intake manifold vacuum pressure and the atmospheric pressure.
When the coil is not energized, continuity exists between the
X-nipple and ambient air. When the coil is energized, continuity
exists between the X-nipple and Y-nipple.
Secondary Air Valve
The secondary air valve turns ON and OFF the secondary
air supply by opening and closing in accordance with the vacuum pressure applied to the diaphragm chamber.

SECONDARY AIR CONTROL
During deceleration from a high speed, secondary air is introduced upstream of the turbocharger. This
operation prevents the turbine’s speed from dropping and thus enhances responsiveness when the driver
next wishes to accelerate. For maximum effectiveness, secondary air is introduced into the exhaust manifold
immediately downstream of each cylinder.
