Would you like to learn about search engine, heat engine, or both? 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? 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 should be specifications of these types of heat engine? What tests are required for these types of heat engine? What do you understand by heat engine speed? Heat engine speed is measured in revolutions per minute (RPM). How do you classify heat engines? What materials are required to manufacture heat engines by use? What specifications should you include in an automobile engine? How do you manufacture an automobile engine? How do you manufacture an aircraft engine? How do you measure heat engine efficiency? 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. |

What is the difference between a gasoline engine and a diesel engine?
What is the difference between a two-stroke and a four-stroke engine? Are there any advantages to steam engines and other external combustion engines? Are there any other cycles besides the Otto cycle used in car engines? Why have eight cylinders in an engine? Why not have one big cylinder of the same displacement of the eight cylinders instead? I am looking to start making engine parts and eventually build my own engine. Where do you obtain the (_______) that is used for piston's and liners? Why does my engine over heat? Why does my engine leak coolant? How a cooling system works How to replace a radiator How does a car heater work? Why wont my car heater work? Why does steam come from the exhaust pipe? Why is there coolant in the oil? |

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 |
