DESC:TECHNICAL FIELD
[001] The embodiments herein generally relate to internal combustion engines and more particularly, but not exclusively to cylinder block assembly and method for coolant flow in internal combustion engines.

BACKGROUND
[002] Generally, an engine cooling system is used to keep an engine of a vehicle operating at optimum temperature by extracting the heat generated by the engine. The two types of engine cooling are air cooling and water cooling. In air cooled engines, cooling of the engine is achieved by passing air over the fins that are provided externally on a cylinder block of the engine. In water cooled engines, cooling of the engine is achieved by circulation of water inside the engine. In conventional water cooled engines, a water pump is used to circulate a coolant to the engine by drawing the coolant from a radiator of the vehicle, such that the coolant first flows through a coolant jacket of the cylinder block and then flows to a coolant jacket of a cylinder head of the engine to absorb heat. The heated coolant is then routed back to the radiator through a coolant outlet provided on the cylinder head. This leads to usage of long coolant hoses/pipes. Further, the method and flow of coolant in the aforementioned engine is subjected to high pressure drop across the cylinder block to cylinder head thereby leading to increased power consumption by the water pump resulting in increased fuel consumption of the vehicle.
[003] Therefore, there exists a need for a cylinder block assembly and a method for coolant flow in an engine, which obviates the aforementioned drawbacks.

OBJECTS
[004] The principal object of an embodiment of this invention is to provide a cylinder block assembly for an engine, which enables cross flow of coolant in the engine thereby facilitating effective cooling of the engine.
[005] Another object of an embodiment of this invention is to provide a method for coolant flow in an engine, which facilitates effective cooling of the engine.
[006] Yet, another object of an embodiment of this invention is to provide a cylinder block assembly for an engine, which enables cross flow of coolant in the engine thereby facilitating reduced pressure drop across cylinder block to cylinder head and reduced power consumption by the coolant pump of the engine.
