Pressurized liquid cooling system for internal combustion engines

Abstract
The report is a proposed pressurized liquid cooling system for an internal combustion
engines. Pressurized liquid cooling system in principle is more effective than other types of
the liquid cooling systems, due to superior heat extraction capacity as well increased range of
the operating performance characteristics. Also the pressurized heat cooling system in the
current report proposed with additional features like pressure bellows to regulate the pressure
during the start up operations to control the heat cooing rate at the critical points during the
start up operations. Also the performance characteristics using range of formulae as well as
the actual advantages of the proposed model presented in the report. Also there Is discussion
on the methodologies of the new technologies and background insights into the existing
technologies discussed appropriately.

Introduction:
Cooling system in internal combustion engines will remove the waste
heat from the internal combustion engines and will keep the system within the
allowable limits of operating temperatures. Such control is necessary for both
optimized operational performance of the engine as well as for the sake of
prolonging the life of the engine material. Most commonly employed cooling
system is air cooling system, where in the air drawn from the environment will
be used to take away the heat from the engine surface; however water cooling
systems is more effective, as it take out more heat in less time from the engine
surface. However this comes with an additional complexity of more weight of
the engine pump and the radiator units. However due to operational difficulties
mostly air engines are confined to low capacity engines, whereas water cooled
engines are used even for power ranges as high as 80MW and more. However
air-cooling systems are justified in the applicatio0ns like low power airplane
engines, where employing air cooling systems is more convenient and preferable
than water cooling systems. Apart from pure water, other types in liquid cooling
include using oil for cooling, using mix of chemical coolants along with water,
using sea water (Specifically for the marine engines) etc., the performance of
each of these models will be better than the pure water cooling system, as the
heat transfer rate will be higher and some times needs less substance than pure
water cooling systems (Ganesan, 2015).
Background
Cooling systems performance requirements typically need to take up about 30%
of the total heat generated in the combustion space. Neither more or less than
this is needed. Also the heat extraction process from the engine cylinder needs
to be faster. However extraction of the heat need to be slower at the start of the
engine, where in all the parts of the engine need to get heated for optimized
performance, once the engine catches up the normal running, the heat removal
rates need to be higher. Principally there are 4 different types of liquid cooling
systems there available, the non-return type of liquid cooling systems, employed
for large capacity HP engines, where there is availability of the plenty of water,
Thermo-syphone, which does not need high rate heat extraction, Hopper cooling
systems, works on the same principle of Thermo-syphone models, where in the
cooing occurs in the jackets of the internal combustion engines. Later models of
water cooling include pumped or forced circulation of water or coolant mixed
