• a computational unit configured to receive said first temperature value and/or said second temperature value, and further configured to compare said first temperature value with a first predetermined

temperature value and said second temperature value with a second predetermined temperature value to determine whether said valve (108) should be operative or inoperative.
3. The system (100) as claimed in claim 2, wherein said computational unit
includes:
• a repository configured to store said first predetermined threshold temperature value corresponding to said first temperature value and said second predetermined threshold temperature value corresponding to said second temperature value; and

6. The system (100) as claimed in claim 1, wherein said valve (108) is a solenoid actuated valve selected from the group consisting of electrically actuated

solenoid valve, pneumatically actuated solenoid valve and thermally actuated valve.
7. The system (100) as claimed in claim 2, wherein said first temperature sensing module is selected from a group consisting of thermistors, resistance temperature detectors, thermocouples, and semiconductor-based sensors.
8. The system (100) as claimed in claim 2, wherein said second temperature sensing module is selected from a group consisting of hermetically sealed resistance temperature detectors sensors, hermetically sealed thermistor sensors, and hermetically sealed thermocouples.
9. The system (100) as claimed in claim 1, wherein said conduit (104) is a metal pipe.
10. The system (100) as claimed in claim 9, wherein a portion of said conduit (104) from said exhaust gas inlet to said oil sump (102) is covered by a layer of heat insulated material.
11. A method for maintaining the temperature of the oil in the oil sump (102), said method comprising the following steps:
a. sensing the temperature of the gas at the exhaust gas inlet of the engine
(106) by a first temperature sensing module to generate a first temperature
value;
b. sensing the temperature of the oil in the oil sump (102) by a second
temperature sensing module to generate a second temperature value;
c. receiving the first temperature value and the second temperature value by
a computational unit;

d. comparing the first temperature value with a first predetermined threshold
value stored in a repository, by a first comparator to generate a first
compared signal when the first temperature value is greater than the first
predetermined threshold value;
e. comparing the second temperature value with a second predetermined
threshold value stored in a repository, by a second comparator to generate
a second compared signal when the second temperature value is less than
the second predetermined threshold value; and
f. operating a valve (108) based on the compared signal by the
computational unit for leading hot gas from the exhaust gas inlet through
the oil sump (102) in a controlled manner when the temperature of the
exhaust gas is greater than the predetermined temperature value and/or the
temperature of the oil falls below a predetermined temperature value to
facilitate warming of the oil.
