different types of fuels used in ic engines

Most of the oil from the pump goes directly to the engine bearings and a portion of the oil passes through a cartridge filter which removes the fluid particles from the oil. When the oil pressure exceeds that for which the valve is set, the valve opens and allows some of the oil to return to the sump thereby relieving the oil pressure in the systems. The strainer is a fine mesh screen that prevents foreign particles from entering the oil circulating systems.Ī pressure relief valve is provided which automatically keeps the delivery pressure constant and can be set to High value. Classification of IC engines based on the method of charging. Classification of IC engines based on the type of fuel used. Here classified internal combustion engines that depend on the. It is collected up by a pump and circulated through the engine lubricating system. Internal combustion engines can be classified into the various several grounds. In the wet sump system, an oil pan is present at the crankcase, sump from which the lubricating oil is pumped to various engine components by a pump.Īfter lubricating these parts, the oil Bows back to the sump by gravity.

For the vehicle moving down the hill, during closed throttle operation the engine will suffer insufficient lubrication as the supply of fuel is less.

This system requires separate mixing to use of some additive to give the oil good mixing characteristics.this will increase the cost.

The corrosion of the bearing surface because the oil comes in close contact with acidic vapors produced during the combustion process.

The mist lubrication system causes exhaust smoke due to the burning of lubricating oil and forms carbon deposits on the piston crown and exhaust ports which reduces efficiency of the engine.Bearing life will increase by up to 150%.The oil mist is injected into the bearing housing for bearing lubrication and the manifold is used to collect the coalesced oil particles from the drop points.
