DL06K Interim Tire-4 Diesel Engine Commissioning and Operation
165
4.2.3. Operating after break-In
When starting a cold engine, always allow the engine to warm up gradually. Never run
the engine at full throttle until the engine is thoroughly warmed up. Be sure to check
the oil level frequently during the first 50 Hr of operation, since the oil consumption will
be high until the piston rings are properly seated.
4.3. Inspections after Starting
During operation the oil pressure in the engine lubrication system must be monitored.
If the monitoring devices register a drop in the lube oil pressure, switch off the engine
immediately. And the charge warning lamp of the alternator should go out when the
engine is running.
z Do not disconnect the battery or pole terminals or the cables.
z If, during operation, the battery charge lamp suddenly lights up, stop the engine
immediately and remedy the fault in the electrical system.
z Engine should be stopped if the color, the noise or the odor of exhaust gas is not
normal.
z Confirm the following things through warning lamps and gauge panel.
4.3.1. Pressure of lubricating oil
The normal pressure comes up to 1.0 ~ 3.0 kg/cm2 (1.0 ~ 3.0 bar) at idling and 3.0 ~
6.0 kg/cm2 at maximum speed. If the pressure fluctuates at idling or does not reach
up to the expected level at high speed, shut down the engine immediately and check
the oil level and the oil line leakage.
4.3.2. Temperature of cooling water
The cooling water temperature should be 75 ~ 90 °C in normal operating conditions.
Abnormally high cooling water temperature could cause the overheating of engine
and the sticking of cylinder components. And excessively low cooling water
temperature increases the fuel consumption, accelerates the wears of cylinder liners
and shortens the engine life-time.
4.3.3. Over-speed control
The electric control unit (ECU) have a system of preventing the engine over-speed
among many system. This system involve many function of fuel flow control, ignition
time delay, fuel shut off, and ignition shut off etc.
These values are set up in advance in the memory of the ECU, and should not be
revised by user.
This engine with ECU should not be run at the over-speed rating speed for a regular
time, if the vehicle is speeded, the fuel and ignition is shut off until the engine speed is
up to the proper level.
