The recommended viscosity for Heavy Fuel Oil (HFO) 380 CST is typically around 380 centistokes (cSt) at 50°C. This viscosity is important for proper fuel combustion and performance in marine diesel engines. It is crucial to maintain the recommended viscosity range to ensure efficient and reliable engine operation.
The viscosity of HFO (heavy fuel oil) varies depending on its grade and temperature. Generally, HFO has higher viscosity than other fuels, such as diesel or gasoline. It has a thick, sticky consistency that makes it more challenging to flow and pump through pipelines and engines, especially at lower temperatures.
It is in use now in both Europe and America.
HFO, or Heavy Fuel Oil, is a type of fuel used predominantly in marine engines. It is a complex mixture of hydrocarbons, sulfur, nitrogen, and other elements. The precise chemical composition can vary depending on the source and grade of the fuel.
HFO-1234yf (2,3,3,3-tetrafluoropropene) is a low-global warming potential refrigerant known for its chemical stability and efficiency in refrigeration and air conditioning systems. It has a boiling point of about -29.5 °C and operates effectively at low temperatures, making it suitable for automotive applications. HFO-1234yf is mildly flammable, classified as A2L, which necessitates specific safety considerations during handling and use. Its environmental characteristics include a significantly lower ozone depletion potential (ODP) and a global warming potential (GWP) of 1, making it a more eco-friendly alternative to traditional refrigerants like HFC-134a.

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.

In the new HFO he does.

all of the answers are true
No. They are completely different refigerants. They are not interchangeable and should not be mixed.
