QUICK FACTS
The HJ SIP ”Swirl Injection Principle” is a cylinder lube oil injection valve that sprays oil in tiny droplets utilizing the centrifugal power of the scavenging air swirl, ensuring optimum distribution of injected oil and thus an efficient use of the lube oil. HJ SIP works on all engine types and designs
- Gain massive savings in cylinder oil
- Reduce particulate matter emission of approximately 25 %
- Achieve optimized cylinder condition
- Injection of cylinder oil above the piston
- Uniform distribution in top of liner – also on super long stroke engines
- Effectively fights the sulphuric acids
- Reduces risk of cold corrosion

Nozzle
The cylinder lube oil is sprayed into the cylinder through the nozzle opening. By spraying the lube oil in tiny droplets, into the scavenging air swirl a large surface area of the liner is covered to ensure optimal distribution of the cylinder oil. This in turn, ensures proper utilisation of the oil.
The nozzle opening is turned at an angle and injects the oil upwards onto the upper part of the cylinder liner where it is most needed, overlapping the next HJ SIP injection point.
-
Pressure plug
Adjustment of closing pressure (35-60 bar) of the HJ SIP valve is done by an adjustable screw on top of the pressure plug. The adjustable screw is kept in place by a lock cover and a screw.
-
Drain pipe
The drain pipe (T) is for the leak oil internally in the HJ SIP valve and is connected to the return pipe where the oil will be recirculated into the system.
-
Pressure pipe
The Pressure Pipe (P), is the oil inlet side of the HJ SIP valve.
The pressurized oil is pumped from the lubricator.
A strainer is mounted in the inlet of the HJ SIP valve at delivery. This must be removed after 500 running hours.
