How To Successfully Parallel Generators ? | Step By Step

How to succesfully parallel generators ? Step by step

When two or more generators with same frequency, voltage and phase difference are connected to the bus-bar; such that it increase their overall capacity, ease of maintenance, and active load management. Then they are called to be connected in parallel; and the method used is called paralleling. While the process used in this method to … Read more How To Successfully Parallel Generators ? | Step By Step

Why And How To Check Fuel Pump Timing in I.C Engine

fuel pump timing relation with engine performance

Have you wondered why some vehicles release visible blackish exhaust while other’s not? The darkness or blackish nature of exhaust gases depends much upon the fuel atomization and fuel pump timing. Proper injection at set point of time will lead to complete combustion producing clean exhaust gas; while any deviation in injection timing results in … Read more Why And How To Check Fuel Pump Timing in I.C Engine

Scavenging In Two Stroke Engine – Types, Advantage & Use

Scavenging In Two Stroke Engine and its types

Understanding scavenging requires us to understand why we need scavenging in first place. We knew that an adequate amount of oxygen is required to start and sustain any combustion. Now since air contains 21% of oxygen; something engine needs in large amount to burn  fuels. Oxygen in form of fresh air is taken in to … Read more Scavenging In Two Stroke Engine – Types, Advantage & Use

Detailed Working of Marine Fuel Pump And Injector

Fuel pump and injector maintaince

Fuel pump and injector directly affects the performance of a marine diesel engine. The quality of combustion in an engine depends on the working of a fuel injector; which leading to proper automation and optimum injection timing. Atomization is the process of breaking fuel in very small particles so that it mix well with the … Read more Detailed Working of Marine Fuel Pump And Injector

Bunkering Operation: Precaution, Procedures & Checklist

Ships require different grades of oil for their day to day operation. The delivery of oil supplies to the ship in the form of fuel and lube oil is refereed to as bunkering. And the process of transferring oil supplies to the ship is termed as bunkering operation. Conventionally bunkering is done in ports but … Read more Bunkering Operation: Precaution, Procedures & Checklist

Effects Of Poor Residual Fuel On Marine Diesel Engine?

Residual Fuel

Proper ignition and combustion of fuel is the key to efficient marine engine. With use of residual fuel for ignition other less important factors become critical; such as the delay period between the fuel injection and ignition. With most of the commercial ships running on residual fuel its obvious to ask; How the use of … Read more Effects Of Poor Residual Fuel On Marine Diesel Engine?

Turbocharger – Function, Construction And Working

basics of turbocharger

How can we increase power of an engine? To generate more power we require more Fuel and Air. Conventionally this was achieved by increasing length of piston stroke or number of cylinders. But what if there’s a way to achieve all without making any change in the engine. Yes! Using Turbocharger we can generate more … Read more Turbocharger – Function, Construction And Working

What’s the need to change Injection Timing? – Variable Injection Timing

Variable injection timing

Have you wondered, whats is the use for variable injection timing or “VIT” if we always learn and told to avoid early and late ignition ! Why am i asking this question? Variable injection timing is a process to alter ignition timing early or late for affecting engine performance. We all know early ignition can … Read more What’s the need to change Injection Timing? – Variable Injection Timing
