SKF cylinder lubrication system for diesel engines

Reliable and durable systems are required for the cylinder lubrication of 2-stroke large diesel engines, as a ship or generator drive. The pulse lubrication system CLU4-C is based on a modular stroke pump with external monitoring electronics in connection with a downstream lubrication nozzle (pulse feed). When using special lubrication nozzles with an integrated spray nozzle, the inside of the cylinder can be wetted with lubricating oil (Pulse Jet).

The stroke pump is hydraulically supplied via two separate lines, the lubricating oil and servo oil lines. These are connected to all stroke pumps. If the 4/2-way solenoid valve is switched to passage by the monitoring electronics of the stroke cycle pump, the servo oil flows to the drive side of the central piston of the stroke cycle pump and actuates it. The central piston moves in the direction of the upper end position and takes the positively guided metering pistons with it. The lubricating oil supplied to the metering channels via the lubricating oil line is dynamically released to the lubricating nozzle under high pressure via check valves.

Their job is to inject the lubricant precisely, for example between the piston rings. Depending on the electronic activation time, the dosing process can take place earlier or later. When using special lubrication nozzles with a spray nozzle, the activation time can also be selected earlier. The spray nozzle wets the cylinder wall. The piston then transports the oil into the upper part of the cylinder so that optimal lubrication and corrosion protection can be achieved.

Depending on the engine type, 6 to 8 lubrication ports per cylinder are supplied with lubricant at the same time. Depending on the load and operating condition, a lubrication pulse is triggered with every 2nd, 3rd, 4th, etc. piston stroke or crankshaft revolution. With different timing, pre-defined lubrication can be achieved at different piston positions. This results in a significantly lower lubricant consumption. At the end of the working stroke, the directional valve directs the servo oil to the return side of the central piston, which thus moves to its starting position. The dosing chamber is filled with lubricating oil and is ready for the next lubrication cycle. The directional control valve is controlled by the motor management.
