Engine Construction Description
The engine is water-cooled, in-line 4 cylinders, 4-stroke-cycle gasoline unit with its DOHC (Double Over Head Camshaft) valve mechanism arranged for "V" type valve configuration and has 16 valves (4 valves/one cylinder). The intake camshaft and exhaust camshaft are mounted over the cylinder head; They are driven by crankshaft through timing chain, and no push rod is provided in the valve train system.
IMT (Intake Manifold Tuning) System Description
The IMT (Intake manifold tuning) system consists of the following items.
- IMT valve (1) included in the intake manifold (2)
- IMT valve actuator (3) fixed on the intake manifold
- IMT vacuum solenoid valve (4)
- Vacuum tank (5)
The vacuum tank contains the one way check valve (6) to maintain negative pressure constantly regardless of variation in the intake manifold pressure.
There fore, the vacuum tank, supplies the IMT vacuum solenoid valve actuator with stable negative pressure in the whole of engine speed ranges.
Scheme 1
The IMT system varies effective length of the intake pipe by opening and closing the IMT valve (1) in order to improve air volumetric efficiency.
As the intake valve in the cylinder head is opened and closed repeatedly, intake air pulsation always exists. If the intake valve is opened when the air pressure is momentarily maximum in the intake manifold, the intake air volumetric efficiency is increased. This momentary maximum air pressure depends on the effective intake pipe length.
When the IMT valve is totally closed [A]
The effective intake pipe length is longer. The engine torque in the low engine speed range and the high engine speed range drops, however it is improved in the middle engine speed range.
When the IMT valve is fully open [B]
The effective intake pipe length is shorter. The engine torque in the low engine speed range and the high engine speed range are improved, however it drops in the middle engine speed range.
The IMT system utilizes above-mentioned characteristic of the engine torque. The IMT valve is closed in the middle engine speed range, and opened in the low engine speed range and the high engine speed range.
In this way, the engine torque is improved in the whole of engine speed range.

| Effective intake pipe length (only in intake manifold) | 420 mm (16.5 in.) at 43 mm (1.7 in.) diameter equivalent path | 270 mm (10.6 in.) at 45 mm (1.8 in.) diameter equivalent path |
SOLENOID VALVE SPECIFICATION
Scheme 4
- The IMRC (Intake Manifold Runner Control) system reduces fuel consumption and exhaust emission by producing the tumble air flow which makes A/F leaner when the engine is idling at low temperature.
- The tumble air flow is generated by opening/closing the IMRC valve located between the intake manifold and the cylinder head.
- The IMRC system consists of the following items. IMRC valve (1) IMRC valve actuator (2) (including in the IMRC valve motor and the IMRC valve position sensor)
- The ECM drives the IMRC valve motor which is included in the IMRC valve actuator according to a vehicle speed, an engine speed, a coolant temperature and an accelerator pedal position.
- When the IMRC valve (1) driving conditions are met, the ECM sends "closing" signal to the IMRC valve motor. The IMRC valve motor closes the IMRC valve to create the tumble air flow (2).
- When the IMRC valve driving conditions are not met, The ECM sends "opening" signal to the IMRC valve motor. The IMRC valve motor opens the IMRC valve.
- The ECM detects an IMRC valve position by a non-contact type IMRC valve position sensor.
IMRC valve closing condition
- Vehicle speed: Stop
- Engine speed: Idling speed
- Engine coolant temperature: Low
- Accelerator position: Fully released

If measured compression pressure is lower than limit value, check installation condition of special tool. If the measured compression pressure of particular cylinder is lower than limit, add a bit of engine oil into the cylinder through the spark plug hole, and then repeat the compression check. If the compression pressure increases after adding engine oil, there is possibility of the following cause. The pressure leakage is caused by worn piston rings or worn cylinder. If the compression pressure does not increase significantly, there is possibility of the following causes. Incorrect valve timing. The pressure leakage is at the valves and the valve seats. The pressure leakage is at the cylinder head gasket. Compression pressure Standard: 1,400 kPa (14.3 kgf/cm 2 , 203 psi) Limit: 1,100 kPa (11.2 kgf/cm 2 , 160 psi) Max. difference between any two cylinders: 100 kPa (1.02 kgf/cm 2 , 14.5 psi)
