The lubrication method is a fully force-fed, full-flow fil-
tration type. The engine oil pump is a trochoid type
which is driven by the crankshaft <4G1>.The engine
oil pump is a gear type which is driven by the crank
-
shaft via the balancer timing belt <4G6>.

Health Warning
Prolonged and repeated contact with mineral oil will
result in the removal of natural fats from the skin,
leading to dryness, irritation and dermatitis. In addi
-
tion, used engine oil contains potentially harmful con-
taminants which may cause skin cancer. Adequate
means of skin protection and washing facilities must
be provided.
Recommended Precautions
The most effective precaution is to adapt working
practices which prevent, as far as practicable, the
risk of skin contact with mineral oils, for example by
using enclosed systems for handling used engine oil
and by degreasing components, where practicable,
before handling them. Other precautions:
•Avoid prolonged and repeated contact with oils,
particularly used engine oils.
•Wear protective clothing, including impervious
gloves where practicable.
•Avoid contaminating clothes, particularly under-
pants, with oil.
•Do not put oily rags in pockets, the use of overalls
without pockets will avoid this.
•Do not wear heavily soiled clothing and
oil-impregnated foot-wear. Overalls must be
cleaned regularly and kept separate from per
-
sonal clothing.
•Where there is a risk of eye contact, eye protec-
tion should be worn, for example, chemical gog-
gles or face shields; in addition an eye wash
facility should be provided.
•Obtain first aid treatment immediately for open
cuts and wounds.
•Wash regularly with soap and water to ensure all
oil is removed, especially before meals (skin
cleansers and nail brushes will help). After clean
-
ing, the application of preparations containing
lanolin to replace the natur al skin oils is advised.
•Do not use petrol, kerosine, diesel fuel, gas oil,
thinners or solvents for cleaning skin.
•Use barrier creams, applying them before each
work period, to help the removal of oil from the
skin after work.
•If skin disorders develop, obtain medical advice
without delay.

IGNITION SYSTEM
ENGINE ELECTRICAL16-30
IGNITION SYSTEM
GENERAL INFORMATIONM1163000100294
This system is equipped with two ignition coils (A and
B) with built-in power transistors for the No. 1 and
No. 4 cylinders and the No. 2 and No. 3 cylinders
respectively.
Interruption of the primary current flowing in the pri-
mary side of ignition coil A generates a high voltage
in the secondary side of ignition coil A. The high volt
-
age thus generated is applied to the spark plugs of
No. 1 and No. 4 cylinders to generate sparks. At the
time that the sparks are generated at both spark
plugs, if one cylinder is at the compression stroke,
the other cylinder is at the exhaust stroke, so that
ignition of the compressed air/fuel mixture occurs
only for the cylinder which is at the compression
stroke.
In the same way, when the primary current flowing in
ignition coil B is interrupted, the high voltage thus
generated is applied to the spark plugs of No. 2 and
No. 3 cylinders.
The engine-ECU or engine-A/T-ECU
turns the two power transistors inside the ignition
coils alternately on and off. This causes the primary
currents in the ignition coils to be alternately inter
-
rupted and allowed to flow to fire the cylinders in the
order 1-3-4-2.
The engine-ECU or engine-A/T-ECU
determines which ignition coil should be controlled
by means of the signals from the camshaft position
sensor which is incorporated in the camshaft and
from the crank angle sensor which is incorporated in
the crankshaft. It also detects the crankshaft position
in order to provide ignition at the most appropriate
timing in response to the engine operation condi
-
tions. It also detects the crankshaft position in order
to provide ignition at the most appropriate timing in
response to the engine operation conditions.
When the engine is cold or operated at high alti-
tudes, the ignition timing is slightly advanced to pro-
vide optimum performance.
When the automatic transmission shifts gears, the
ignition timing is also retarded in order to reduce out
-
put torque, thereby alleviating shifting shocks.
