What is the difference between internal combustion engine and heat engine?
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.
What invention did internal combustion engine make possible?
The internal combustion engine made possible the invention of automobiles, which revolutionized transportation by providing a faster and more convenient way for people and goods to travel long distances. It also played a critical role in the development of other industries such as aviation, agriculture, and manufacturing.
Can water be used as fuel in internal combustion engine?
No, water cannot be used as a direct fuel in an internal combustion engine. However, water can be used in a process called electrolysis to produce hydrogen, which can then be used as a fuel source in internal combustion engines.
The source of thermal energy in an internal combustion engine?
The source of thermal energy in an internal combustion engine is from the combustion of fuel (such as gasoline or diesel) inside the engine cylinders. The controlled explosion of the fuel-air mixture generates heat energy that is converted into mechanical energy to power the vehicle.
What is an example of an external combustion engine?
Examples of external combustion engines:
1) wood-burning or coal burning steam-powered locomotives
2) coal and oil-fired boilers on steamships
3) Stanley Steamer, an early steam-powered motorcar
4) nuclear reactors
Toxic gas produced by internal-combustion engines?
Carbon monoxide (CO) and nitrogen oxides (NOx) are the primary toxic gases produced by internal combustion engines. These gases can have harmful effects on human health and the environment, contributing to air pollution and smog formation. It is important to reduce emissions from engines through proper maintenance and use of emission control technologies.
Convert kw to cubic capacity of an internal combustion engines?
You can't, because they're all different.
I'm going to use horsepower instead of kW here because I'm an American and that's how we think; if you'd like to convert to kW, one HP is roughly 750 watts.
Let us examine the very common 1.6 liter engine. Every automaker has built one and they're all different. A Volkswagen Beetle 1.6 liter engine produced somewhere between 50 and 60 HP. Honda made one that put out about 120 HP. Mini Coopers have available to them an engine of the same size that makes 180 HP, and the 2014 Formula 1 race engine is a 1.6 liter V6 that makes 600 HP.
How was the internal combustion engine invented?
The internal combustion engine was invented in the 19th century by various engineers and inventors, with Nikolaus Otto being credited for developing the first practical four-stroke engine in 1876. The engine's design evolved through the contributions of many others, including Karl Benz and Gottlieb Daimler, leading to the creation of the gasoline-powered engine that revolutionized transportation and industry.
Why is there incomplete combustion in an internal combustion engine?
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 is more dense in colder weather, leading to more oxygen in each cc3 of air introduced to the cylinder and petrol is not going to be precisely the same throughout either. The aim of engine designers is to get a close match which results in an efficient as possible engine without too high a cost to the end user.
What device mixes air and petrol for the internal combustion engine?
The device that mixes air and petrol for the internal combustion engine is the carburetor. It controls the air-fuel ratio to ensure efficient combustion in the engine.
What does an internal combustion engine run on?
an internal combustion engine means the source for ignition burns internally so the power gets soon without any loss. an external combustion means the source of ignition was outside so there was loss so less efficiency. an internal combustion engine means the source for ignition burns internally so the power gets soon without any loss. an external combustion means the source of ignition was outside so there was loss so less efficiency.
What year was the internal combustion car invented?
The internal combustion engine-powered car was invented in 1885 by Karl Benz, who is often credited with creating the world's first automobile.
E2 technology (Energy and Environmental) refers to strategies and solutions that focus on improving energy efficiency and reducing environmental impact. This can include technologies such as renewable energy sources, energy-efficient appliances, smart grid systems, and sustainability practices in various industries to minimize carbon emissions and promote a healthier environment.
What are the four strokes of a internal combustion engine?
The four strokes of an internal combustion engine are intake, compression, power, and exhaust. During the intake stroke, air and fuel are drawn into the combustion chamber. In the compression stroke, the mixture is compressed. The power stroke is when the compressed mixture is ignited to create power, while the exhaust stroke expels the burned gases from the chamber.
Who built the first combustion engine?
In 1859 a Belgian engineer Jean Joseph Étienne Lenoirdeveloped the first internal combustion engine for gas.
It was a single-cylinder two-stroke engine which burnt a mixture of coal gas and air ignited by a spark-ignition system. He patented it in 1860.
Then Nicolaus Otto invented a gasoline motor engine in 1876. He built the first practical four-stroke internal combustion engine - called the "Otto Cycle Engine" - and built it into a motorcycle.
Otto's patent was later revoked when it was contested by Beau de Rochas.
Why petrol engines called constant volume engines?
In a engine, well 99.9% of them the piston is conected to a crank via a conrod, as nothing changes during the strokes of the piston and the cylinder bores dont change.
The swept volume of the stroke is always constant.

= Internal Combustion = The Âprinciple 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 into potato motion. You can also use it for more interesting purposes. For example, if you can create a cycle that allows you to set off explosions like this hundreds of times per minute, and if you can harness that energy in a useful way, what you have is the core of a car engine!
Figure 1 Almost all cars currently use what is called a four-stroke combustion cycle to convert gasoline into motion. The four-stroke approach is also known as the Otto cycle, in honor of Nikolaus Otto, who invented it in 1867. The four strokes are illustrated in Figure 1. They are: * Intake stroke * Compression stroke * Combustion stroke * Exhaust stroke You can see in the figure that a device called a pistonreplaces the potato in the potato cannon. The piston is connected to the crankshaft by a connecting rod. As the crankshaft revolves, it has the effect of "resetting the cannon." Here's what happens as the engine goes through its cycle: # The piston starts at the top, the intake valve opens, and the piston moves down to let the engine take in a cylinder-full of air and gasoline. This is the intake stroke. Only the tiniest drop of gasoline needs to be mixed into the air for this to work. (Part 1 of the figure) # Then the piston moves back up to compress this fuel/air mixture. Compression makes the explosion more powerful. (Part 2 of the figure) # When the piston reaches the top of its stroke, the spark plug emits a spark to ignite the gasoline. The gasoline charge in the cylinder explodes, driving the piston down. (Part 3 of the figure) # Once the piston hits the bottom of its stroke, the exhaust valve opens and the exhaust leaves the cylinder to go out the tailpipe. (Part 4 of the figure) Now the engine is ready for the next cycle, so it intakes another charge of air and gas. Notice that the motion that comes out of an internal combustion engine is rotational, while the motion produced by a potato cannon is linear(straight line). In an engine the linear motion of the pistons is converted into rotational motion by the crankshaft. The rotational motion is nice because we plan to turn (rotate) the car's wheels with it anyway.
Is a boiler an internal combustion engine?
No, a boiler is not an internal combustion engine. A boiler is a closed vessel that uses heat to generate steam or hot water for heating or power. Internal combustion engines, on the other hand, are machines that generate power by burning fuel within a combustion chamber.
What is a combustion reaction?
Any rxn that is (generally) and organic molecule + O2 -> H2O + CO2
Thats just generally what it looks like.
Ancient Greeks such as Empedocles and Heraclitus were among the first to theorize about combustion. However, the modern understanding of combustion as a chemical reaction involving oxygen was developed by scientists such as Robert Boyle and Antoine Lavoisier in the 17th and 18th centuries.
What a heat engine does What a heat mover does?
A heat engine converts heat into mechanical energy, typically by using the heat to produce steam and drive a turbine. A heat mover, on the other hand, transfers heat from one place to another, such as in a refrigerator or air conditioner, by using a refrigerant to absorb and release heat through a thermodynamic cycle.
When was internal combustion engine invented?
The internal combustion engine was invented in 1876 by German engineer Nikolaus August Otto. Otto's engine, commonly known as the "Otto engine," was the first successful four-stroke engine and revolutionized the way people think about and use engines. The internal combustion engine has since become a crucial technology for powering everything from cars and boats to generators and airplanes.
What is used to measure fluids?
You can measure fluids in beakers, graduated cylinders or liquid measuring glasses. It depends on what you're measuring and why.
Does a tachometer in an internal combustion engine measure crankshaft revolutions per minute?
Yes, a tachometer in an internal combustion engine measures the crankshaft revolutions per minute (RPM). The tachometer provides real-time feedback on the engine's speed and helps the driver or operator monitor and control the engine's performance.
How powerful was the engine in Concorde the airplane?
Rolls-Royce/SNECMA Olympus 593 Mark 610 turbojets. With afterburner, each of four engines produces 38,050 pounds of thrust on takeoff. Take-off thrust is limited for only a few minutes and after-burner is very limited. For normal operation, the thrust is 10,000 lbs. Powerplant Specifications Engine Model Olympus 593 Mrk610 turbojet Engine Manufacturer Rolls-Royce/SNECMA Number fitted Four Maximum thrust produced at take off, per engine 38,050 lbs (170 KN) (with afterburner reheat in operation) Maximum thrust produced during supersonic cruse, per engine 10,000 lbs Reheat contribution to performance 20% at full thrust during take-off This link has some great info and figures on the Concorde engines and a comparison ofwith the turbo-fan engines(watch for pop-up windows). http://www.concorde-jet.com/e_moteurs.htm The Concorde jet engine is a standard turbotjet with after-burner, much like the fighter jets. Most airliners utilize the turbo-fan engines. This engine has a jet engine as the main core and one of its turbines powers a large multi-bladed fan that blows air over the outside of the engine. This is why it is called a high-bypass turbo-fan. This design uses fuel more efficiently to save costs for the passengers. As a comparison to the Concorde engine, General Electric has designed theCF6-80E1A3 for use on the Boeing 777 thatproduces a thrust of72,000 lbs at takeoff.
