2. RESONANCE FLAP
1) Function
A pneumatically actuated resonance flap (5)
is located on the intake manifold, and will be
opened and closed by load, which operates
resonance flap according to engine and
controlled by ECU and rpm.
Resonance flap closed (at idle/partial
load: less than 3,800 rpm)
The switch valve (7) will be adjusted by
ECU and resonance falp will be colosed.
By increasing air flow passage through
dividing intaking air flow toward both ai
r
collection housing (8).
This leads to a signficant increase in the
torque in the lower speed range. ▶
Resonance flap open (at full load:
over 3,800 rpm)
The switch valve (7) will not be adjusted
by ECU and resonance falp (5) will be
open. The collected air in the ai
r
collection housing (8) will not be divided
and intaking air passage will be shorten. ▶

ENGINE CONTROL SYSTEM
RODIUS 2005.07
0452-01
When driving (part/full throttle), the servo motor controls the throttle valve in line with the
various load states and according to the input signals from the pedal value sensor according to
the input signals from the pedal value sensor according to the position of the accelerator pedal.
The function of the EA (electronic accelerator) in the ECM determines the opening angle of the
throttle valve through the throttle actuator.

1. OVERVIEW
DCAG 5-speed automatic transmission is an electronically controlled 5-speed transmission with
a lockup clutch in the torque converter.
The ratios for the gears are realized by three planetary gear sets. The 5th gear is designed with
a step-up ratio of 0.83 as an overdrive. The selector lever is controlled by electronically and
mechanically.
The gears are shifted by the corresponding combination of three hydraulically actuated
multiple-disc brakes, three hydraulically actuated multiple-disc clutches and two mechanical
one-way clutches.
This electronically controlled automatic transmission adjusts the operating pressure to provide
proper shifting in relation to engine power. This function improves shifting quality significantly.
And, the driver can select “S” (Standard) mode or “W” (Winter) mode according to the
driving conditions.
This automatic transmission provides two gears even during reverse driving.
The internal sensors and controls are connected to TCU by cylindrical 13-pin connector.
DCAG 5-speed automatic transmission offers the following advantages ▶
Improved shifting quality
More gears
Extended working life and reliability
Reduced fuel consumption -
