VOLVO D7D Engine Cylinder Liner Kit For EC240/EC290 20450773 Loader Engine Parts Low Tension Piston Rings 1004016A300

CASE the excavator engine

​​​​

Electronic control system:

It uses signal inputs from a number of sensors to determine the amount of fuel to be fed to the engine and the lead-in. The engine Control box (ECM-- Electronic Control Module) is loed on the left side of the engine. It has two sockets, each with 50A pins, for signal input and output. With the exception of the throttle sensor, idle sensor, and moisture sensor (water in diesel), the engine is connected to the front 50-pin socket, and the other electrical sockets are connected to the rear 50-pin socket edge. Needle socket connection.

Advantage of Engine Cylinder Liner Kit

• Greater resistance. Making liners separately from the engine block allows the use of special higher performance materials than those used for the construction of the block itself. Liners are generally made in special cast iron alloys containing elements with natural lubriing properties, like graphite. Other components are added like chrome, vanadium, and molybdenum to help ensure resistance to corrosion and wear caused by high temperatures.

• Easier maintenance. When liners are worn they can be replaced more easily than changing an entire cylinder block.

• Higher thermal conductivity. At operating temperatures the liners heat up more than the cylinders and must be able to expand in both diameter and length. If they were cast together with the cylinders, the resulting thermal loading would be high enough to fracture the materials.

• Less risk of defects. The more complex a casting, the more difficult it is to achieve perfectly even surfaces with low residual stresses.
