77IV. Exhaust Pipe Discharges Gas with Abnormal Color (or odor)When there is failure in engine combustion system, the exhaust pipe discharges gas with abnormal color.
1. The discharged gas is thickly black
This is caused by incomplete combustion. Since the mixed air is too thick, the combustion is not complete and
part of the fuel is discharged without combustion, leading to decrease of engine power. At this moment, you
should check fuel pressure regulator, throttle position sensor, injector and ECU system and correct the
problems in time.
2. Exhaust is blue and stinks
This is caused by large amount of oil vapor mixed in the exhaust gas that enters in the cylinder and partici-
pates in combustion. One of the primary reasons is that the piston oil ring is dirty and damaged, and shall be
replaced; another reason may be the failure of valve oil seal or excessive clearance between the valve stem
and guide bush hole resulting in oil entering the combustion chamber for combustion, oil seal or valve guide
bush shall be replaced to resume normal condition.
3. Exhaust is white
This is caused by water or fuel vapor mixed in the exhaust. The primary reason is that cylinder head gasket
is damaged, resulting in slow infiltration of coolant into cylinder and the water vapor entry into the exhaust
pipe after combustion, cylinder head gasket shall be replaced to resume the normal condition.Section 3 Engine Noise Diagnosis and TroubleshootingAbnormal sounds generated during engine operation (e.g. knocking sound, chuckle, hiss, rattle) are called
noise.
Engine noise is primarily generated in valve train, connecting rod piston crankshaft components and other
accessory system. The following description discusses the diagnosis and troubleshooting of the noise gener-
ated in valve train and crankshaft connecting rod mechanism.I. Diagnosis and troubleshooting of the noise in valve trainvalve train consists of intake & exhaust camshaft , valve, valve bushing, tappetand counter gear.
1. camshaft noise
(1) camshaft end play is excessively big (normal intake camshaft : 0.030~0.085mm, exhaust camshaft : 0.
035~0.090mm) , when it exceeds 0.11mm and noise is generated, replace it;
(2) Camshaft bend is another cause for noise; it shall be aligned or scraped. ;
(3) Camshaft journal is excessively worn, resulting in big radial clearance between camshaft and bearing and
noise, replace it;
2. Valve group knock noise
(1) Valve noise is caused by excessive valve clearance, the valve spring seat flange is damaged and shall be
replaced;
(2) Valve spring knock noise is caused by broken valve spring. It shall be replaced;

843. Output Level
ECU output level is designed to send control signal to the actuators of the electronic control system based on
the orders of the microprocessor in the micro-controller. The microprocessor control the output level by
controlling the occurrence position of the pulse, its length and duty ratio.
(1) Injection output level
The microprocessor controls the pulse length of the injection output level by making sure whether to
trigger to circuit or not in the injection output level.
(2) Ignition input level
The ignition output level is designed to amplify the ignition signal from the microprocessor into the primary
current of the ignition coil.
(3) Electric fuel pump output level
ECU microcontroller control the pump relay through electric fuel pump output level, and then control the
on and off of the electric fuel pump based on the current operating conditions.
(4) Other output levels
Control the output levels of the idle control valve, carbon canister solenoid valve, malfunction indicator
lamp. MR479Q, MR479QA, MR481QA engine idle control are closed loop control system, their injection
and ignition control are also closed loop control system.

103Chapter 5 Front Suspension SystemSection 1 Front Suspension SystemDescription on front suspension structure
This model uses strut swing arm independent suspension with stabilizer bar.
The shock absorber upper end is flexibly connected to the body through the shock absorber mounting seat,
the lower end is rigidly connected to the steering knuckle. The coil spring encloses the shock absorber (coil
spring geometrical axial line does not coincide with that of the shock absorber piston rod), and is supported
between the upper and lower spring seats.
Both ends of the stabilizer bar are connected to the shock absorber through the strut bar ball pin and the
intermediate part is supported on the lower front body by the rubber bushing and support frame.
The front cushion sleeves the shock absorber piston rod head to restrict the wheel jump limit position and
plays the role of buffer.
The thrust ball bearing, installed between the spring upper seat and the shock absorber mount, is used for the
relative rotation upon steering of the shock absorber rigidly connected to the steering knuckle to the shock
absorber mount flexibly connected to the body.
"L" type lower swing arm is secured to the lower engine compartment with the press plate through elastic
rubber bushing and hinge, and its outer end is connected to the steering knuckle through the ball stud pin
which is attached to the lower swing arm by 3 high intension bolts. The ball stud pin can be removed and
replaced when it is worn.
The ball seat material is saturated polyester containing oil, featured in comparatively high intensity and
wearability and good self-lubrication performance. Proper amount of grease has been added during the
assembly and there is no need for additional filling during the normal operation.
