The inspection when KT(A)1150 diesel engine break-in test

The inspection when KT(A)1150 diesel engine break-in test
During the engine running, the following must be checked regularly.
Engine oil
1. When the engine reaches normal operating temperature after the engine at a certain speed and load, it’s oil pressure should be maintained at or close to a fixed value (idle 1.1 kg / square centimeter, the rated speed of 3.2-4.9 kg / cm) does not normal oil pressure is too high may indicate that the oil plug, not the normal low hydraulic oil pump may indicate insufficient, or because of damage caused by oil film bearing clearance increases.
2. If the oil temperature rapidly increased by more than 107 °C, should turn off the engine and check to be addressed as needed.
3. To put the new oil filter to absorb oil, so the engine is running 5 to 10 minutes later, we must stop, coupled with the injection oil to the oil dipstick on the plane to “H” mark the height of the run-in trial period, each stage To check the oil level.
Engine coolant
After starting the engine, filling the coolant as needed to fill the cooling system to remove air inclusions. During the engine operation, coolant temperature should not exceed 93 °C, or less than 7l °C.
After the operation with a load, can not shut down the engine immediately. If you take the heat when the engine when the air and cooling liquid stop the cycle, then the stored heat in the iron parts of the coolant will boil in the water jacket, so that the engine should be shut down before the idle a few minutes.
Deceleration stop device.
When the engine speed exceeds the maximum rating of about 15%, the abundance of speeding stop device (if used) should be adjusted to cut off the fuel pipeline from the road to the role of speed in identifying and excluding the reasons for stopping work after installation, re-adjust location of its movement
Engine fuel consumption.
ST-1190 fuel consumption measuring device, work-inch oil from the tank through the fuel injector return flow from the oil, the introduction of the float tank, when the fuel tank full inch, float valve opens to allow oil return flow to supplement the fuel flow meter amount of fuel consumed or the engine, flow meter, so showing in pounds / inch fuel consumption, refer to the Notice No. 3,379,068, “fuel pump manual correction.”
Channeling gas readings
1. In the run-in pressure during the test must always read the meter reading, it will give the technician noticed a certain operating speed and load, channeling gas has increased. If signs of increased channeling gas, the engine speed must be reduced for several minutes, then come back to the original rate to rise
2. During each test function, we should always pay attention to check the pressure meter; if the pressure rise that need more time on the run.
3. If the end of the experiment, the pressure is greater than the value specified should be the engine at 96-100% of rated load and speed, and then run 30 minutes if not more than 50.8 mm after the dramatic changes in the water column, or on behalf of readings does not exceed limit of the pressure, the gas is allowed channeling.
Note: The pressure fluctuations in the value of the meter reading should not be more than 7.62 mm.
