This is another on-demand post and its purpose is to explain the 4-stroke lubrication system from operational point of view. All running gear of the 4-stroke engine is forced lubricated by an engine-driven gear type pump which takes the oil from the engine sump tank. The same oil from engine sump tank is also provided…
Regular engine performance test helps in evaluating the current condition of engine and optimizing engine performance. Performance test of engines will also help in identifying drop in its performance due to any deteriorating condition related to exhaust valve, fuel injector etc. If possible, the engine cylinder balance must be checked as often as possible. Measurements…
Filters remove particles from liquids and gases, decreasing wear and tear on downstream systems and increasing operating stability and dependability. Filters should have a high level of cleaning efficiency, create minimal resistance, have a high impurity pick-up capacity, and be simple to clean. Filters eliminates solids in the flowing media undergoing filtration, almost completely above…
Author – Daniel G. Teleoaca – Marine Chief Engineer Understanding the Scavenging Air System The turbocharger uses the exhaust gas from the engine to compress new air and charge the engine with a positive pressure higher than ambient conditions. Exhaust gas temperature convection and compression raises the temperature of the air and this cannot be…
I believe that most of the marine engineers encountered, at least once in their career a turbocharger surging. This is not a pleasant experience, especially if you a in the close proximity of the turbocharger when at such happens, due loudly noise and backpressure effect. Turbochargers are designed to match the engine and balance the…
