What is the difference between search engine and heat engine?

What is a search engine?


A search engine is a set of programs of various software used to search and display as per specific keywords, specific data, or information.

What is a heat engine?

A heat engine is defined as a device of durable materials that converts heat or thermal energy into useful mechanical motion.

Laws of thermodynamics, enthalpy and other concepts will clarify the issues.

Types of heat engine by use

What are the types of heat engines by use?
Aircraft engines
Automobile engines
Model engines
Motorcycle engines
Marine propulsion engines such as outboard motor
Railway locomotive engines
Spacecraft propulsion engines such as rocket engine
Traction engines


There are various classifications of heat engines.

This type of classification is most useful.

After elaborating these types of heat engines, elaborate specific heat engine by use.

1. Internal combustion engine( combustion of fuel takes place internally)
2.External combustion engine( combustion of fuel takes place externally)

There are two types of internal combustion engine
1. Reciprocating
2. Rotary

Even the internal combustion engine used for automotive is sub-categorized into-
1. Spark ignition engine (Working on Otto cycle).
2. Compression ignition engine (Working on Diesel cycle).

Some of the other important classification of internal combustion engine is based on working cycle or number of piston strokes.
1. Four stroke.
2. Two stroke.

What are the categories of aircraft engines?

Categories of various types of heat engine by use

What are the categories of automobile engines?

There are at least 18 categories of automobile engines.

What are the categories of model engines?

What are the categories of motorcycle engines?

What are the categories of marine propulsion engines?

What are the categories of rocket engines?

What are the categories of traction engines?

How do you manufacture these types of heat engine?

What do you understand by heat engine speed?

Heat engine speed is measured in revolutions per minute (RPM).

What is thermal energy?
Laws of Thermodynamics

First law of thermodynamics: Energy and matter are interchangable but cannot be created or destroyed. The total amount of energy in the whole universe remains constant, only changing from one form to another.

Second Law of thermodynamics: This law states that any system always tends to move toward its probable state of energy. For example, a spring watch will run until the potential energy in the spring is used up. If no new energy is input into it (in the form of winding the spring up) then it has returned to its most probable state, which is really not to run. The most misunderstood law.

Third Law of Thermodynamics: This law is a little more complicated and deals with the state of a system of atoms and molecules at an absolute zero temperature. Absolute zero is theoretically impossible to achieve considering any force acting upon the atoms and molecules to remove heat from them are not at absolute zero and therefore cannot make anything else reach absolute zero. The third law says that entropy of atoms and molecules at absolute zero is zero.

How do you measure heat engine efficiency?

Measures of engine performance Engine types vary greatly in a number of different ways: energy efficiency fuel/propellant consumption (brake specific fuel consumption for shaft engines, thrust specific fuel consumption for jet engines) power-to-weight ratio thrust to weight ratio Torque curves (for shaft engines) thrust lapse (jet engines) Compression ratio for piston engines, overall pressure ratio for jet engines and gas turbines

How do you classify heat engines?

The engine are classified based on combustion (ignition), fuel used, cooling, application and constructions.

Based on the combustion type : 1. External combustionengines and 2. Internal combustion engines

Based on fuel used : 1. Diesel engines, 2. Petrol engines, 3. CNG engines and LPG engines

Based on cooling system : 1. Air cooled engines and 2. Liquid cooled engines

Based on applications : 1. Statinary engine 2. Rocket engine and 3. Automobile engine

Based on construction : 1. Inline engines, 2. Opposed engines, 3. Rotary engine, 4. V-engines and 5. W engines
