Chapter 5 Front Suspension SystemSection 1 Front Suspension SystemDescription on front suspension structureThis 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.See the table for the front suspension technical parametersFront Suspension SystemFront Suspension System4-38Item

compressor, condenser and evaporator etc, it adsorbs heat in the air through circulation of refrigerant, so as to
reduce air temperature in car body and eliminate water vapour in air, to achieve the purpose of temperature drop
and dehumidification. Heating system mainly consists of heat exchanger and heater unit. It utilizes heat of engine
cooling water to heat air via heat exchanger, so as to achieve the purpose of heating. Regulation and control of
temperature, humidity and flow rate of air in car body is realized via heating and refrigeration systems separately
or jointly.
For parameters of refrigerating system, see the table:

General Information

Fault symptom
Flameout, poor idle speedChapter 9 Engine EFI SystemI. Outline This system includes sensor that detects engine functioning. Engine ECU utilizes sensors installed at differ-
ent parts of engine to measure various working parameters of engine, accurately control oil injection quantity
according to control procedure set in engine electronic control unit, so engine could work in optimum mode
under various operating conditions, i. e. optimal power output, the most economical oil consumption, optimal
exhaust emissions. Engine ECU is capable of start up control, idle speed closed-loop control, air fuel ratio
closed-loop control, canister control, transient operation control, angle of ignition control, knocking control, air
conditioning control, coasting fuel cutoff and overspeed fuel cutoff control, ternary catalyst heating and protec-
tion control, system self-diagnosis etc.II. Inspection of control element1. Manifold intake pressure temperature sensor
(1) The part to measure intake pressure is piezo type sensor, could provide controller with "load signal "
according to the difference between atmospheric pressure and manifold pressure; controller will supply 5V
voltage, and feed back 0-5V voltage to controller according to different intake pressures. The part to measure
intake temperature is NTC type (negative temperature coefficient) sensor, resistance changes with intake
temperature, this sensor conveys a voltage representing intake temperature change to the controller.
(2) Simple measuring method:
Temperature sensor part: (remove joint) turn digital multimeter
to Ohm position, two meter pens connect sensor 1 #, 2 # pinrespectively, rated resistance is 2. 5k ohm±5% at 20°C, correspond-ing resistance value may be measured from the above characteristic
curve. Simulation method may also be used for measurement, spe-
cific procedure is to use electric drier to blast sensor (pay attention not
to be too close), observe change of sensor resistance, here resistanceEngine EFI System-Engine EFI System5-120Possible cause
There is abnormal high voltage or reverse heavy current during useVacuum
unit is damaged during repair
Repair precautions: it is prohibit to use high pressure gas to impact vacuum unit during repair; when replace
sensor case of trouble, check whether generator output voltage and current is normal or not.1 2 3 4Manifold intake pressure temperature

Fault symptom Possible cause
Poor speedup etc Man made fault1 2 3Throttle position sensorFault symptom Possible cause
Difficult to start Man made fault Repair precautions: pay attention to mounting position.
(2) Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect
two meter pens with sensor 1 #, 2 # pin respectively, its resistance
value at room temperature is 2k ohm±20 %. Connect two meter pens
with 1 #, 3# pin respectively, rotate throttle, its resistance value shows
linear change with opening of throttle, while situation is reverse for
2 #, 3# pin.
Note: when observe change of resistance value, pay attention to observe whether has large leap.
3. Coolant temperature sensor
(1) This sensor is a negative temperature coefficient (NTC) thermistor, its resistance value decreases with
increase of temperature, but not a linear relationship. This thermistor is installed in a copper heat conducting sleeve.Engine EFI System-Engine EFI System5-121should drop.
Pressure sensor part: (connect joint), turn digital multimeter to DC voltage position, black meter pen is earthed,
red meter pen is connected with 3#, 4# pin respectively. In condition of idle speed, 3# pin should have reference
voltage of 5 V, 4 # pin voltage should be about 1. 3 V (specific value is related with vehicle type); in no-load
condition, open the throttle slowly, change of voltage of 4 # pin is not large; open the throttle quickly, voltage of
4 # pin may reach about 4V in no time (specific value is related with vehicle type), then it drops down to about
1. 5 V.
2. Throttle position sensor
(1) This sensor is actually corner potentiometer with linear output characteristic. Potentiometer tumbler is
mounted coaxially with throttle, when throttle rotates, it drives potentiometer tumbler to slide to certain position,
potentiometer outputs voltage signal proportional to throttle position. Mounting torque: 20 N.m(Max)
(2) Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect two meter pens with sensor pins respectively,rated resistance at 20°C is 2.5 k ohm± 5%. Simulation method may also be used for measurement, specificprocedure is to put sensor work area into boiled water (pay attention to soak for sufficient time), observe changeof sensor resistance, now resistance should drop down to 300 ohm-400 ohm (specific value subjects to temperatureof boiled water).

4. Knocking sensor
(1) Knocking sensor is a vibration acceleration sensor. Mounted on engine cylinder body. Sensing element of
the sensor is a piezocrystal. Vibration of engine cylinder body is transferred to piezocrystal via mass block in the
sensor. Since pressure generated by vibration of mass block is applied to piezocrystal, it generates voltage on two
polar planes and turns vibration signal into voltage signal for output.5-122Symptom
Poor accelerationPossible cause
Various liquids, such as engine oil, cooling fluid, brake fluid, water etc
contact the sensor for a long time, which cause corrosion to the sensor. Mounting torque: 20 ± 5 N.M
Repair precautions: sensor must be fitted closely to cylinder body with its metal surface, any type of washer
is not permitted for installation. For wiring of sensor signal cables, note that do not let resonance occur to signal
cables, otherwise they might be broken. Energizing of high voltage between sensor 1 # and 2 # pins must be
avoided, otherwise piezoelectric element might be damaged.
(2) Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect two meter pens with sensor 1 #, 2 # pin
respectively, its resistance value at room temperature should exceed 1M ohm. Turn digital multimeter to millivolt
position, use a hand hammer to tap near knocking sensor, now voltage signal output should be available.
5. Oxygen sensor
(1) Its sensing element is a ceramic tube, outside is open to exhaust, inside is open to atmosphere. When
temperature of sensing ceramic tube reaches 350°C, it will have the characteristic of solid state electrolyte. Just
utilizing this characteristic, it converts concentration difference of oxygen into electric potential difference, thus
forms electrical signal output. If mixed gas is a bit concentrated, inside and outside oxyanion concentration
difference of ceramic tube is high, electric potential difference is a bit high.
A large number of oxyanions move from inside to outside, output voltage is high (approximate 900mV); if
mixed gas is a bit thin, inside and outside oxyanion concentration difference of ceramic tube is low, electric
potential difference is low, only a small quantity of oxyanions move from inside to outside, output voltage is low
(approximate 100mV).
Possible cause
1. humid water vapor ingresses inside of sensor, temperature
changes rapidly, probe is broken.
2. oxygen sensor "is poisoned". (Pb, S, Br, Si) Symptom
Poor idle speed, poor speedup, tail gas
overproof, too high oil consumption1 2 3 4Oxygen sensor Mounting torque: 40-60 N.m
Repair precautions: it is prohibited to use cleaning fluid, oily liquid or volatile solid on oxygen sensor during
repair.
(2) Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect
two meter pens with sensor 1# (white), 2# (white) pin respectively, its
resistance value at room temperature is 1- 6 ohm.
(Connect joint) in idle speed condition, when oxygen sensor
reaches its working temperature of 350°C, turn digital multimeter to
DC voltage position, connect two meter pens with sensor 3# (grey),Engine EFI System-Engine EFI System
