What is choke in an internal combustion engine?
The choke is used on petrol engines with carburettors, to increase the fuel to air ratio, for better starting.
It is called a 'choke' because it actually chokes off some of the air entering the carburettor and is a simple metal flap across the air intake.
By choking off some of the air, a greater vacuum is formed, which draws more fuel from the jets.
A cold engine requires slightly more petrol than a warm engine for the spark to ignite the mixture. Once warm, the engine needs less fuel in the mixture (14:1 , air:fuel)and will run rough and waste fuel if the choke is left on.
Modern engines do not have carburettors or chokes, being fuel injected.
The choke function is taken care of by a cold start program where the computer varies the quantity of fuel injected with respect to the air mass and temperatures.
Diesel engines also need a 'cold start device', but this is not a choke. As diesels are injection engines, this is taken care of by changing the fuel pump setting via a switch, or by computer control of common rail injectors.
An internal combustion engine is the main part of a vehicle. It transforms the gas in a car into energy to run on.
This is because there is either more fuel to oxygen; too rich a mixture, or more oxygen to fuel; too lean a mixture. To get the mix precisely correct may be theoretically possible but would lead to a very expensive, complex engine management system as the air being introduced for each fireing of each cylinder would have to be analysed for it's number of oxygen molecules and the number of molecules of petrol matched. Air… Read More
Because it was found that ICEs deliver power more simply and weigh less than ECEs.
maybe bec. theres two types of i.c.e. the gasoline and diesel ingine
No because there isn't any combustion happing inside the boiler the water is heated by an external flame and boils the water.
If the lawnmower is not electric powered then is is probably operated by an internal combustion engine (petrol or diesel. Oddly enough, very early lawnmowers were steam powered, which means they were examples of external combustion engines.
What is the most important difference between an internal combustion engine and an external combustion engine?
in internal combustion engine combustion happens internally in cylinder and in external combustion engine combustion happens externally in boiler
There are way too many answers for that question. Basically any machine that uses natural gas, diesel fuel, petrol (Gasoline-USA) and kerosene will be driven by an internal combustion.These include most road going vehicles, most earthmoving equipment, marine vessels as well as a lot of fixed plant; generators, compressors refrigeration plant etc.Some electric vehicles are driven via a generator that runs of an internal combustion engine. Diesel-electric locomotives are a classic example of this.
1 (One) crankshaft. There may be 1 or 2 camshafts but always 1 crankshaft.
Internal combustion engines burn a fuel in the presence of oxygen in order to create thrust or compression (to drive an engine or turbine). The fuel can be any of the following (although there are others): Petrol Diesel Oil Gas Butane Methane Kerosine
Internal engine has its energy ignited in the cylinder. like 99.9% of engines today An external combustion example is a steam engine where the heating prosses is done in an boiler out side the engine.
In an Internal Combustion Engine, the fuel is burned in the cylinder or vessel. Eg. Diesel or Petrol engine used in Cars. Internal engine has its energy ignited in the cylinder, like 99.9% of engines today. In an External Combustion Engine, the internal working fuel is not burned. Here the fluid is being heated from an external source. The fuel is heated and expanded through the internal mechanism of the engine resulting in work. Eg… Read More
YES the oxidizer and propelant are mixed into a chamber the ignited.
They become oxides of nitrogen or the emission NOx, this is controlled by the EGR valve to lower combustion temperatures and lower the NOx gas wich contributes to phot chemical smog, the stuff you see in the air.
a functioning properly insulated and sealed internal combustion engine is only designed to burn gas... though when malfuntioning is able to burn anything that comes in contact with it (i.e. anti-freeze and/or oil) if that happens then blue smoke (if it's burning oil) will come out the tail pipe... if it's burning antifreeze then thick white smoke (think smoke screen) will come out the back of the tailpipe.. if all is well then you might… Read More
Exhaust, which is made up of different carbon compounds such as co2, co, ect.
sunil is really gay and sucks a call of duty 4!!!!!! There are several types: gasoline and diesel fueled are the two main types. Within those they have various combustion cycles: 2 cycle, 4 cycle, otto cycle, atkensen cycle, wankle cycle are some that apply to gasoline engines. The thing they all have in common is combustion is fully contained in a sealed chamber(s) inside the engine on a fixed charge of fuel and air… Read More
An internal combustion engine burns the fuel inside the engine itself, i.e. gasoline burning in the cylinders. An external combustion burns the fuel outside the engine, i.e a steam engine on a locomotive.
This sounds like a home work question. But as I don't know what your teacher wants for an answer. I will discuss what I know. Nickel is: A high hardness metalCan be and is used in alloysIs relatively inexpensive for its propertiesIs very resistant to corrosionCan be plated to other materials (The coating system most used in automotive)This all makes it ideal to coat other materials to increase the wear resistanceIn alloys it tends to… Read More
If I understand the question this is caused by liquid getting in the cylinder and the liquid not allowing the engine to turn over.
"Part Load" is short for partial load. "Load" is when the engine is doing work. Whatever work the engine is doing places a "load" on the engine which resists the engine's turning motion and slows the engine down so it requires more throttle to maintain speed. "Partial load" is when the engine is doing work that would stall the engine at idle, but does not require full throttle, just partial throttle. A good example would… Read More
Not very. only about 15% of the energy is used to drive your car on the road. 62% of the energy is used up in the engine itself, converting the gas to energy. 17% is used when the vehicle idles. 5% is expended in the transmission 2% is used for accessories.
Temperatures in the combustion chamber can reach 4,500*F or 2,500*C.
Gasoline is a hydrocarbon obtained by separating crude oil into component fractions in a fractionating column; so yes a hydrocarbon can power an internal combustion engine.
Essentially, they are the same, pressurised gas in a closed cylinder forcing a piston along which turns a crank via a con rod converting linear to rotary force.The main difference is how the pressurised gas is delivered:In an internal combustion engine, fuel and air are sucked into the cylinder, valves are closed, fuel/Air is ignited, combustion takes place, heat makes pressure.So the pressure by combustion is created inside the cylinder (internally)In an external combustion engine… Read More
The combustion stroke is where all of the power from an engine is derived making it the most important however the other strokes play a role in how well the combustion process is completed. Each stroke is vital in the process of combustion.
The external combustion engine ( a steam engine is a good example) burns it fuel to create an energy source that is then transported (piped) to a device to create mechanical motion.The internal combustion engine burns its fuel inside the device creating the mechanical motion (piston car engines and Aircraft jet engines are two examples)
The source of thermal energy in an internal combustion engine is from a combination of pressure (the piston compressing the air/fuel mixture), ignition of air/fuel mixture by spark plug (largest contributor), and friction of moving parts inside the engine.
All fossil fuel, and biodeisel engines are internal combustion engines. Internal combustion engines are engines that requier a propellant (Gas, diesel etc..). The fuel gets injected into the engine and mixes with air, the mixture gets injected into a cylinder, a piston compresses the mixture and then a small spark from a spark plug ignites the mixture. this lets the engine drive a shaft that can be connected to a number of things, tires, lawnmower… Read More
carbon monoxide, due to improper combustion Hydrocarbon and nitrogen oxidesAlso, if the fuel contains sulfur, oxides of sulfur
lean mixture..results to increase NO2,, increasing the fuel will reduce NO2 but increase carbon monoxide, so the EGR is developed to reduce NO2 without increasing the fuel in turn increasing the CO.
Examples of internal combustion engines: Gasoline engine in a car, where fuel-air mixture burns inside a cylinder and the expansion pushes a piston coupled to a crankshaft. Diesel engine works exactly as described above for a gasoline engine, except that the fuel requires no spark to ignite (and other differences in detail). Gas turbine engine in a jet or turboprop airplane or helicopter, where fuel-air mixture burns inside a turbine and the expansion pushes the… Read More

What is the average temperature inside the combustion chamber of an internal combustion diesel engine?
the air temp at the end of the compression stroke for the ignition of diesel fuel within the combustion chamber is approx between 450*c - 675*c Brent
What is the average temperature inside the combustion chamber of an internal combustion petrol engine?
Any where between 1500-3000 Fahrenheit (800-1700 Celsius) Type in "Martin Vagn Hansen thesis" in Google, You will find his thesis on measuring flame temps in IC engines.
Its purpose is to open the right valves at the right times.
Engine types based on stroke :1. Two stroke engine (in which ignition is takes place twice that is in incoming stroke and second in outgoing stroke )2. four stroke engine (in which 4 process are done that is Suction,compression,power transmission and exhaust. and ignition is takes only once ) There are two types of engine commonly named as : 1. Spark ignition engine 2. Combustion engine here are many types of engine such as inline… Read More
There are many components but the most noteable are the block, head, crankcase, cylinder, piston, piston rod, crank shaft, camshaft, and flywheel.
Dr R Diesel in 1892, A German engineer, Brent
Hi, this is from www.howstuffworks.com New HCCI Engine * More Auto Videos » = Internal Combustion = The principle behind any reciprocating internal combustion engine: If you put a tiny amount of high-energy fuel (like gasoline) in a small, enclosed space and ignite it, an incredible amount of energy is released in the form of expanding gas. You can use that energy to propel a potato 500 feet. In this case, the energy is translated… Read More
a gasoline engine is an Internal combustion engine
Why combustion of gasoline occurs more rapidly in an internal combustion engine than in open container?
There is a complicated physics/chemistry answer for this question and a "mechanic" answer. I will give the mechanics answer. I am assuming that you are asking this question in regards to a specific amount or volume of gasoline, because the obvious answer otherwise would be that the fuel is being pumped in the engine at a high rate and an open container is just....sitting there. With a specific amount of gasoline, in a container, the… Read More
