1.2.2.10. Controls and Instruments

The diesel engine is controlled remotely, from the operator’s place. The diesel engine

controls and instruments are to be mounted by the user when installing the engine in the tractor

(machine).

The rotational speed of the crankshaft is changed by means of the fuel pump governor

lever. When moving the lever to the rearmost position (towards the flywheel) the engine runs at

the highest rotational speed and when moving the lever to the extreme front position (towards the

fan) the fuel feed is shut (turned off).

When starting the diesel engine, the electric torch pre-heater and starter are switched on

by means of the three-position switch of the VK-316-B type. When the switch is set to the I posi-

tion, the electric circuit of the heating coil of the pre-heater is energized, when it is set to the II

position, the starter circuit is closed and the fuel valve of the pre-heater is opened.

The instruments for monitoring the diesel run are located in the tractor (machine).

The pressure gauge of oil in the lubricating system is connected to the union of the cen-

trifugal oil filter via the oil duct. The sensor of the emergency oil pressure alarm of the D-243, D-

245 diesel engines is located in the housing of the centrifugal oil filter and the sensor of the emer-

gency coolant temperature alarm is mounted in the thermostat housing.

The sensor of the air-cleaner clogging alarm is mounted in the intake path of the diesel

engine.

The sensor of the coolant temperature gauge in the cooling system is located in the cyl-

inder head.

The crankshaft rotational speed and the number of engine service hours are monitored by

means of the tachometer with the counter of the number of engine service hours driven from the

engine camshaft via flexible shaft and reduction gear.

The number of running house of the D-242 and D-244 diesel engines can be monitored

also by means of the SCh-114B up counter mounted on the camshaft cover instead of the reduc-

tion gear and driven from the camshaft.

The air compressor is controlled by means of the handle located on its housing. To en-

gage of disengage the compressor, it is necessary to set the handle to the required position.
