spark ignition technology was first developed more than fifteen years ago and has proved very popular for power generation on land. Dry Masses Bergen K engines have dry masses between 22500 and 30500 kg Longevity These marine diesel and gas engines have design lives of more than 20 years and engines are installed in more than 150 power plants throughout the world. Bergen K-G4 (discontinued) Also available as a gas engine for powers from 1190 – 3970 kW the Bergen K-G4 lean burn gas engine is the result of development based on the K type diesel and heavy fuel oil engine parent. Bergen B32:40 and 35:40 The Bergen B Series is a twenty-year-old (est. 1986) marque of reciprocating diesel engines. They serve a wide range of ocean-going vessels and; can be supplied as propulsion units or as generator sets for the provision of electrical power. The range includes in-line and Vee cylinder configurations. The liquid fuel engine has a cylinder bore of 320 mm and a stroke of 400 mm. The gas fueled engine has a 350 mm bore with the same stroke. The Bergen B Series Marine Diesels have power outputs in the range 2,880 - 8,000 kilowatts These engines have a reputation for being "a Rolls-Royce product" in terms of quality which is ironic because when they were designed, the company was not part of the Rolls-Royce organization. The Bergen B35:40 gas engine has high power and efficiency in the 720-750 rpm class and, is designed for low emissions of NOx, CO, and UHC combined. It builds on the latest B diesel hardware, specifically redesigned and modified for the gas variant.
