System: Main Engines, 3 pcs. For example, your diesel engine will go through a break-in period, in which it will consume more oil. The core of this technique is to measure the concentration of atomic sulfur in the exhaust gas stream while running sulfur-free fuel (actually 1.0 to 1.2 ppm) and sulfur-containing oil (around 4000 ppm), … With the unit running at minimum operating speed and the frame lube oil at operating temperature, 170°F (77°C), set the … Oil consumption primarily occurs near or through the combustion chamber, either downward through valves or upward past the piston ring-pack. Brake specific fuel consumption (BSFC) is a parameter that reflects the efficiency of a combustion engine which burns fuel and produces rotational power (at the shaft or crankshaft). Wärtsilä 6R32. A lubricant refers to a substance that makes parts of something move smoothly and liquid lubricants account for about 80% of it. On most equipment such as pumps, compressors, winches and the like, lubricant levels need only regular checks and the occasional change.
