YC4108D.YC4108ZD series diesel
engines are developed by Yuchai in the purpose of satisfying the diesel generator set market requirement.
This model bases on the
foundation of high - quality product YC4108Q, YC4108ZQ, and assimilate the
diesel engine technique characteristics of generator set,which is the
amalgamation of our company’s abundant experience and overseas advanced
technology. YC4108ZD engine bases on the model of YC4108D engine, adopt exhaust
gas turbocharging technique, which is good in motive force and fuel efficiency
and meet the emission and low noise requirement, The series has good
performance in motive force fuel efficiency and dependency. The model, compact,
simple, easy maintenance.
This manual introduces the main
technical specifications.the basic assemblage requirements,the engine
adjustment.the operation and maintenance and the troubleshooting of the
YC4108D.YC4108ZD engine. Proper operation and maintenance will prolong the use
life and ensure safety in operation. Please read this Manual carefully before
use, and pay special attention to CAUTIONS ON ENGINE USE. To ensure the engine
use properly and maximize the clients economic effectiveness, please make the
engine maintenance work actually.
This manual is only about the
basic model of this series generator set,which is the same for operation and
maintenance the modified models. As requirements for technology is developed so
fast,modification will be carried out without information.
YC4108D/YC4108ZD series diesel
engine generator uses the advanced technical design, the quality reliable, the
service life is long, has the good power and the efficiency. In order to enable
the machine the high performance to obtain a better display, and guaranteed the
machine the safe operation, invites you before the use first in detail reads
the textbook instruction for use below, and specially pays attention “the safe
driving matters needing attention”.
Cautions On Safe Driving
The oil pressure gauge
probe,water temperature gauge probe,and particularly the low pressure alarm are
the three very important components,of which immediate replacement is required
for any malfunction. It is desired to always maintain the normal function of
these components,any failure to comply with that may easily lead to crankshaft
bum due to oil shortage or cylinder head crack due to overheat from water
shortage.
After cleaning the oil filter
gauze or during the process of replacing filter gauze, it should be noted to
reinstall the filter only after refilling oil fully,and start the engine on
idle running immediately after reinstallation; meantime,check if there is any
sign of leakage to any filter. Correct the leaking filters or it may easily
lead to crankshaft burn caused by oil short-age.
Each time you start the
vehicle,first start the engine on idle running for 5 to 10 minutes till the
engine warms up and all gauges working in normal function,then start to move.
Never put the vehicle to sudden acceleration from cold - start. For any
dramatic speed - up on cold status will dam-age the instruments and their
corresponding parts and components and accelerate the wear and tear of engine's
kinetic parts,consequently it will shorten the engines life cycle.
Start the engine on first gear,no
chugged idling.
Avoid any sudden stall and
quenching the engine at high speed,high load status,the appropriate way is to
gear down the engine gradually and stop the vehicle after 5-10 minutes of
engine idle running.
Strictly adjust the injection
advance angle of the turbocharger engine according to the requirements
specified in the Operation Manual. When the engine power is decreasing,first
check the intake pipe to find if there is any leakage and check the air cleaner
for the clog of stuff.
Anytime you find the vehicle
and/or engine is not working normally, stop it immediately to correct the
malfunction ,never allow the vehicle running under an abnormal state.
Don't directly touch the high
temperature parts ( such as exhaust pipe) of the engine when you check it,don’t
open the radiator cover immediately just after stop,for this may cause physical
burn.
Send the engine to a consignment
technical service station of Yuchai for a run - in serviced when it reaches its
first 1500 - 5000 km of mileage, or you will the warranty for this engine.
Anti-freeze coolant shall be used
in the cooling system; otherwise no quality guarantee will be born by the
Manufacturer.
The engines normal working
condition is -150C ~400C in temperature and below 2000m in altitude,any
operation under water or in fire are prohibited. Clean the air filter gauze
during dusty and windy condition, replace the filter gauze immediately once it
is found to he damaged. Please consult Yuchai's technical or service
departments for working below 15℃ or above
400C or over 2500m in altitude, so that effective measures can be taken to
ensure normal function.
Operate and maintain the engine
improperly will lower the engine performance of power,economy,emission and life
cycle,and also do harm to the environment. The cause and troubleshooting can be
founded in the table I.table II table III and " safety caution".
Hoisting and transporting the
engine according to the notes on the engine s package, and store the engine in a condition of
dry,clean,good ventilate and with no corrosiveness things. The engine's storage
is no longer than 12 months( counted from the ex - factory date).
Please open the radiator cap in
the meantime while adding water to the diesel engine.
