Heat can be removed from engine in three different ways.
· Conduction : transfer of heat through solid
· Convection : heat transfer by movement of molecules of substance
· Radiation : transfer across spaces as rays such as use of fins.
But, in internal combustion engine, usually heat is removed by passing coolant through air passages around engine blocks through radiator which absorb the heat by air passing over the fins and through radiator core.
Air flow is assisted by Fans
No, refrigerators and air conditioners are not examples of heat engines. Heat engines typically convert heat into mechanical work, while refrigerators and air conditioners transfer heat from one location to another using a refrigeration cycle.
An example of a reaction that gives out a lot of heat is the combustion of gasoline in engines. This reaction releases a large amount of energy in the form of heat and light.
The work of Sadi Carnot, a French engineer, on the efficiency of heat engines in the early 19th century led to the formulation of the second law of thermodynamics. Carnot's insights on the limitations of heat engine efficiency laid the foundation for the development of the second law, which eventually became a fundamental principle in thermodynamics.
Fire can "go away" if it runs out of fuel, is extinguished by water or another fire retardant, or if the conditions necessary for it to exist, such as heat, oxygen, and fuel, are removed. The extinguishing method depends on the type of fire and its surroundings.
The three elements necessary for combustion to take place are fuel, oxygen, and heat. Fuel provides the substance to burn, oxygen is needed for the reaction to occur, and heat is necessary to initiate the combustion process.
A necessary input for all heat engines is a high-temperature heat source to provide the thermal energy needed for the engine to operate. This heat source drives the conversion of heat energy into mechanical work through a thermodynamic cycle, making it an essential component of the engine.

You can do it if you remove the heat shield it works.
engines get discolored because of the heat . the heat comes from combustion from gass and air
by engine
Yes. Gasoline and diesel engines are both heat engines.
Yes. Heat engines come in various forms. For example, internal combustion using gasoline or diesel, external combustion (not much used), steam engines reciprocating or turbine, gas turbines, rocket engines.
heat engines are classified on the location of the combustion chamber , if it is outside the whole set up then it is external heat engine and vice versa.
A car engine is a heat engine, but there are various types of heat engines outside the realm of car and truck engines.
No, refrigerators and air conditioners are not examples of heat engines. Heat engines typically convert heat into mechanical work, while refrigerators and air conditioners transfer heat from one location to another using a refrigeration cycle.
An internal combustion engine is a type of heat engine that generates mechanical energy by burning fuel inside the engine. A heat engine, on the other hand, is a broader category of engines that convert heat energy into mechanical work through various processes, including combustion, thermodynamic cycles, and heat transfer. In essence, all internal combustion engines are heat engines, but not all heat engines are internal combustion engines.
