Cylinder LS
Pure Tech Cylinder LS is a special 40BN, SAE 50 cylinder lubricant, for improved piston running conditions in low speed crosshead diesel engines burning low sulphur fuels.
PERFORMANCE, FEATURES & BENEFITS
Reliable engine performance:
- Reduced piston deposits: The reduced ash level of Pure Tech Cylinder LS helps to avoid excessive piston top land deposits, which can sometimes build up when 70BN oils are used with low sulphur fuel.
- Greater feed rate flexibility: The control of deposits and lower ash allows Pure Tech Cylinder LS to be used over a wider range of feed rates with less danger of excessive deposits, than a 70BN cylinder oil.
- Good piston ring and port cleanliness: Pure Tech Cylinder LS contains “hidden” detergency, not reflected in the BN of the product. This enables it to keep the ring belt and scavenge air ports clean in spite of the reduced BN.
MAIN APPLICATION
- Cylinders of low-speed crosshead diesel engines burning fuels with sulphur content below 2%wt, where the designer recommends a lower Base Number (BN) oil to reduce the risk of “sudden severe wear” or scuffing.
