What else can I help you with?
Is it possible to construct a heat engine that produces no thermal pollution?
Atmospheric engines, or 'Stirling' engines, can make use of waste or naturally occuring heat differences, to work.
How does a heat engine differ from steam engine?
A heat engine is a broad term that encompasses any device that converts thermal energy into mechanical work, utilizing various heat sources and cycles. A steam engine, on the other hand, is a specific type of heat engine that primarily uses steam as its working fluid, typically generated by boiling water. While all steam engines are heat engines, not all heat engines are steam engines, as heat engines can also use gases or other fluids in their operation. The principles of operation may vary based on the type of working fluid and thermodynamic cycle employed.
How does a jet engine divert the heat flow to perform work?
Depends on the engines manufacture. most use a bleed air valve which takes air off the low pressure stages. this method of utilizing the heat for other purposes such as deicing the wings or providing heat to the cabin also improves the accleration of the engine.
Why can't the heat generated by a combustion engine can be used as a source of energy instead of cooling engine and wasting it?
What you are after is perpetual motion, which isn't going to work. Any type of energy can be converted to heat, but heat can only partially be converted to energy. Most of the problems stem from trying to remove heat, rather than allowing it to accumulate. Heat is the graveyard of energy. ------------------------------------------------------------------- Some heat from engines can be recovered and used for space heating. The heaters in automobiles do just that. However, more often than not the build up of heat from an engine is more than is desired for auxiliary uses, and it must be discarded to keep from overheating the equipment. Some building emergency generators can use some of that heat in a heat exchanger for heating non-domestic water supplies, but the potential for leaks precludes it from use for domestic water heating.
When should you use em heat on the thermostat?
EM (or emergency heat) can be used if you have a problem with your other heat source such as a heat pump. In most cases, you will not need this but what it does is bi-passes the primary heat source and allows your secondary heat source (normally your furnace) to become the primary.
Does heat engines use heat to do work?

How do heat engines use heat to do mechanical work?
Heat engines convert thermal energy into mechanical work by utilizing the principles of thermodynamics. They absorb heat from a high-temperature source, which causes a working fluid (like steam or gas) to expand and perform work, typically by moving a piston. As the fluid expands, it does work on the surroundings, and then it releases some heat to a lower-temperature sink before being compressed to repeat the cycle. This continuous process allows the engine to convert a portion of the absorbed heat energy into useful mechanical work.

Do internal combustion engines use a heat sink?
Many engines use a Heat Sink. The most common are air cooled engines like a lawn mowers, or some motorcycles. The metal fins you see around the spark plug and the cylinder are heat sinks. A heat sink just provides additional surface area for the heat to be exchanged with the cooler temperature of the air.
How do heat engines use thermal energy and how do refrigerators keep things cold?
Heat engines use thermal energy to generate mechanical work by transferring heat from a high-temperature reservoir to a low-temperature reservoir. Refrigerators keep things cold by using a refrigerant to absorb heat from the inside of the unit and release it outside, thereby maintaining a lower temperature inside.
Air-cooled engines use what form of heat transfer to remove most of the heat from their cylinder head and cylinder?
C. Convection

Explain what heat engines do and name the process in which they use to burn fuel?
Combustion
How does fossil fuel work?
You burn it; it gives off heat; you use the heat.
Do diesel engines require spark plugs?
No diesel engines use the "heat of compression" to cause fuel to ignite not electrical ignition.
Can heat be converted other types of energy?
The most common method is to convert the heat into steam and use the steam to drive mechanical devices such as engines and turbines.
