In addition to finding the "sweet spot" as the other poster indicated which is the RPM and load that the engine uses the least amount of fuel per KWm HFO reduction can also been realized by using new technology, E-Fuel.
E-Fuel, reduces emissions as traditional emulsions but in the case of HFO can increase the fuel efficiency using HFO up to 38% in a rotating engines.
There are two reasons that the 38% effective can be reached, the heavies don't have to be removed from HFO to prevent damage to the engine and the fuel is 43% more efferent in converting the HFO into mechanical energy.
MDO and HFO prices for ships
no it should increase fuel consumption as the oxygen sensor should compensating by adjusting the engine to run rich.
its consumption by one person does not reduce its consumption by others.
taxation helps in having fear of more consumption because of chance of losing more money so people reduce consumption .
Hypofluorous acid
No, there is not. There are lots of devices that claim to reduce fuel consumption but none of them actually work. Not one.
HFO = Heavy Fuel Oil 380 CST = the grade of fuel oil representing viscosity, quality, etc.
The simple answer is "yes" it does. Adding ANY load to the engine will reduce its efficiency by some degree.
Drink less.
Why the fuel consumption is less in 4 stroke engine as compared to 2 stroke engine
The consumption of lubricating oil for a diesel engine depends on the operating conditions and the design of the engine. There are some averages depending on the year of the engine. Pre 1980's engine are around 25% of fuel consumption. Pre 1990 engines are around 20% of fuel consumption and more recently built diesel engines are around 1% of fuel consumption.
Depends on the type of engine
