Protection For Stationary Natural Gas Engines
Gas-powered engines are being used increasingly for power generation, various types of pumps and other ancillary machinery for site services.
Many maintenance engineers recognise the need for specialised lubricants that address common problems such as carbon deposits and port blockages. Other issues on gas engines used for continuous severe-service operation include valve recession and wear on piston rings, cylinder liners and bearings.
Although most gas engines are environmentally cleaner at the exhaust pipe, seriously abrasive particles will often find their way into the oil. To optimise return on investment in equipment, the installation of sub-micron oil filtration such as an oil centrifuge is also recommended for these applications.
AMSOIL® distributor, Enginecare Systems Australasia, says Amsoil Synthetic Stationary Natural Gas Engine Oil (ANGS) delivers continuous protection in stationary natural gas engines calling for an SAE 40, low-ash lubricant.
“Its shear-stable formula qualifies it as a multi-grade 20W-40 so it can be used over a broad ambient temperature range, eliminating the need for seasonal oil changes. This product is formulated with low sulphated ash to minimise carbon deposits and port blockage, resulting in reduced maintenance and extended equipment life,” said Enginecare Systems’ Laurie Hyland.
“Premium base oils and additives are designed to improve engine lubrication by keeping oil passages clean. The balanced formula of ANGS allows for a high total base number (TBN) to protect against corrosion while meeting low ash requirements.
“Nitration is a common concern in natural gas engines and can cause oil to thicken, reducing operational efficiency. This oil is naturally resistant to nitration, delivering maximum protection in natural gas engines.
In addition, low zinc and phosphorus levels prolong the life of emission catalyst systems without sacrificing wear protection,” Laurie said.
The company says Amsoil Synthetic Stationary Natural Gas Engine Oil is recommended for use in stationary four-stroke and select two-stroke engines that require low-ash (<.50%) engine oil and are fuelled by natural gas. The oils is recommended for use in gas engines produced by major manufacturers including, Cummins, Caterpillar, Jenbacher, MAN B&W, MWM Deutz, Wärtsilä NSD and Waukesha.
