7. VVT-i (Variable Valve Timing-intelligent) System
General
The VVT-i system is designed to control the intake camshaft within a range of 40 (of Crankshaft Angle)
to provide valve timing that is optimally suited to the engine condition. This realizes proper torque in
all the speed ranges as well as realizing excellent fuel economy, and reducing exhaust emissions.
Using the engine speed signal, vehicle speed signal, and the signals from mass air flow meter, throttle
position sensor and engine coolant temperature sensor, the ECM can calculate optimal valve timing for
each driving condition and controls the camshaft timing oil control valve. In addition, the ECM uses
signals from the camshaft position sensor and crankshaft position sensor to detect the actual valve timing,
thus providing feedback control to achieve the target valve timing.

11. Charging Control
General
This system lowers the generated voltage when the vehicle is idling or is being driven at a constant speed,
and raises the generated voltage when the vehicle is decelerating. This reduces the load on the engine as
a result of the electric generation of the generator, thus contributing to the fuel economy of the engine.
During acceleration, this system regulates the generated voltage in order to place the amperage estimation
value close to the target value.
This control consists of the ECM, battery current sensor with a built-in battery temperature sensor,
generator, and various sensors and switches.
The ECM detects driving condition based on signals from various sensors and switches, and detects
charging condition based on signals from the generator, battery current sensor and battery temperature
sensor. Then the ECM outputs signals to the IC regulator to control the genetated voltage of the generator.
The ECM stops the charging control and the generator switches to normal power generation mode under
the following conditions:
Low battery capacity
Low or high battery temparature
Wipers operating or blower motor operating with tail lamp relay ON

2. Air Cleaner
A nonwoven, full-fabric type air cleaner
element is used.
A charcoal filter, which adsorbs the HC that
accumulates in the intake system when the
engine is stopped, is used in the air cleaner case
in order to reduce evaporative emissions. This
filter is maintenance-free.
Along with the use of the air intake control
system, an air intake control valve is provided
on the air cleaner case. For details, see page
EG-128.
Resonators have been provided to reduce the
amount of intake air sound.
3. Throttle Body
A linkless-type throttle body in which the throttle position sensor and the throttle control motor are integrated
is used. It realizes excellent throttle valve control. For details, see page EG-118.
In the throttle control motor, a DC motor with excellent response and minimal power consumption is used.
The ECM performs the duty ratio control of the direction and the amperage of the current that flows to
the throttle control motor in order to regulate the throttle valve angle.

IGNITION SYSTEM
1. General
A DIS (Direct Ignition System) is used. The DIS improves the ignition timing accuracy, reduces high-voltage
loss, and enhances the overall reliability of the ignition system by eliminating the distributor.
The DIS is an independent ignition system which has one ignition coil (with igniter) for each cylinder.
2. Ignition Coil
The DIS provides 6 ignition coils, one for each
cylinder. The spark plug cap, which provides
contact to the spark plug, are integrated with an
ignition coil. Also, an igniter is enclosed to
simplify the system.
