we need order.

Read the text and do exercises:

Firstly, oil mist goes to the connection box.The mist is from the crankcase. There are pipes on the left and on the right, which are connected with the siphones on the crankcase.

Ejector sucks mist from the engine.

We use shock absorbers not to pass vibration from the engine to the measuring head.

Engineers must control the condition of shock absorbers.

Oil Mist Detector Part 3

infrared led beam – инфракрасный светодиодный луч receiving photodiode – приемный фотодиод

too much oil – слишком много масла cannot reach – не может достигнуть reflect from – отражаться от

alarm activates – активируется тревога

Put the words in gaps:

– Sunlight reflects from water.

– If the sensor fails to detect any movement for twenty seconds, an alarm activates.

– goes through oil mist.

– Beam must reach the not to activate the alarm.

– The engine is eating…………………….

– I the control panel.

Read the text and do exercises:

There is an infrared led beam and a receiving photodiode inside of the measuring head.

If there is too much oil in the mist, the infrared led beam cannot reach the receiving photodiode. It reflects from the oil. Alarm activates and then shut down of engine.

Put words in the gaps:
