HYUNDAI I:IMSEN D/G STARTING PROCEDURES

HYUNDAI I:IMSEN D/G STARTING PROCEDURES
	1.Preparation of the Engine for Starting
▬	Electric power ''ON'' for the control system.
▬	Check functions of monitoring panel,local and remote control,etc.
▬	Check cooling water tank level and fill,if needed.
▬	Operate cooling water supply system,if stopped.
▬	Check valves and set operation position.
▬	Check and correct any leakages.
▬	Check air venting in the cooling water circuit.
▬	Check water pressure and temperature.
	2.Preheating of the Engine
	Preheating of the engine is required for protecting the engine from thermal
	shock as well as proper circulation of fuel oil and lubricating oil.
▬	Operate cooling water heating system,if installed and necessary.
NOTICE:	Make sure to circulalate heating water through the cylinders at least for
	2 hours before starting.Temperature of the water shall be depending on
	the fuels for starting as below.
	●	Starting on HFO:over 60˚C
	●	Starting on MDO:over 40˚C
	3.Preparation of Fuel System
▬	Drain fuel tanks for water and check filters.
▬	Check fuel tank level and fill,if needed.
▬	Check cooling system for diesel fuel oil.
▬	For starting on HFO,recheck preheating of the engine ready for HFO circulation.
WARNING	Emergency cold satrting on HFO is not accepted.Cold engine may cause clogging
	of the fuel injection system by heavy fuel oil,which may cause serious damages
	on fuel injection system due to excessively high fuel injection pressure when
	starting.
NOTICE:	IF engine stopped on HFO without heating continuously,The HFO inside fuel
	injection system should be removed and cleaned by MDO before re-starting.All
	fuel injection pumps,valves and high pressure pipes should be dismantled and
	cleaned.
▬	Operate fuel supply system,if stopped.
▬	Check valves and set to operating position.
▬	Check any leakages and correct them.
▬	Check air venting in the circuit.
▬	Check fuel oil temperature,viscosity and pressure.
	4.Preparation of Lubricating Oil System
▬	Check oil sump tank level and fill,if needed.
▬	Check valves and set them to operating position.
	5.Pre-lubrication of the Engine
▬	Check lubricating oil temperature.
NOTICE:	If oil temperature is too low or oil viscosity is higher than normal 1500 cSt (10˚C SAE40)
	electric motor for pre-lubricating pump may be overloaded.
▬	Operate Pre-lubricating pump,if stopped.
▬	Check and correct any leakages of the system.
▬	Check Oil pressure rise and pre-lubricating condition.
NOTICE:	Prelubricating should be continued at least for 5 minutes before starting.If the engine
	has been stopped for period of time overhauled,make sure that oil comes out from
	bearings,rollers on cam and rocker arms on cylinder heads.Tapes attached du-ring
	maintenance may block the oil passages..
▬	Open Indıcator Cock.
NOTICE:	If there is any doubt abaut dry condition on running surface of cylinder liner,drop
	lubricating oil about 50cc through indicator cock and spray lubricating oil under
	the piston before turning the engine.
▬	Engage turning gear and rolate crankshaft manually at least two turns to ensure
	engine moving parts are in order and combustion chamber are free from any excessive
	fluid,i.e,water or lubricating oil or fuel oil.
NOTICE:	If there is any sign of escaping fluid through indicator cock,wrap the indicator cock
	with cleaning rags to avoid the fluid scattering over.And turn the crankshaft to ensure
	no escape of fluids from cylinder.
NOTICE:	Fuel remained inside cylinder before starting may cause over pressure and heavy
	smoke during starting.
▬	Disengage from turning gear.
	6.Preparation of Starting Air System
▬	Drain air tank for water and check filters
▬	Check air tank pressue and fill,if needed.(20~30bar)
▬	Check control air pressure.(5~7bar)
▬	Check valves and set the operating position.
▬	Check any leakages and correct them.
	7.Preparation of Fuel Control System
♦	Check smooth movement of fuel regulating linkages from governor to every rack
	of the fuel injection pump.
▬	Check 'Stop' and 'Max' position for both Governor Load Index and Fuel Pump rack.
▬	Check function of 'Emergency Stop' button and reset.Push the handle on fuel regulating
	shaft 'Max' position and press 'Emergency Stop' button,then every rack of fuel injection
	pump should be extruded to 'Stop' position.
▬	Check flexibility of each rack of fuel injection pump.Rack of fuel injection pump should
	be returned to original position when pushing or pulling it manually.
▬	Check mechanical fuel limiter for over load (Set 110% load).
NOTICE:	If mechanical fuel limiter is not set correctly,the engine may be seriously damaged.
▬	Check mechanical fuel limiter for over start (Set about 50% load).
	8.Air Running
▬	Check  if engine load is removed.(Set governor speed knob to minimum to prevent fuel entering)
▬	Check indicator cock opened.
▬	Check air intake and exhaust gas passages are free.
▬	Check 'Start Ready' lamp 'ON'.
▬	Check  if engine load is removed.(Set governor speed knob to minimum to prevent fuel from
	entering)
▬	Press 'Start' button and check air running condition.
▬	Close indicator cock.
▬	Press 'Start' button again and check air running condition.
NOTICE:	Air running is recommended to ensure pre-lubrication and rediness for starting,if
	only possible.
