What is the source of energy for the strokes other than power stroke in 4 Stroke engines?

There are intake and exhaust "cycles". A 2 stroke goes so much quicker because it it simply intake exhaust, generating power rather fast compared to the 4 cycle engines making power in the cycle half as often. The valving on 4 strokes allows for many things but they are never quite as quick as two stroke engines.

What energy source was used to power steam engines?
water
What energy source can you use in cars?
Internal combustion gasoline, propane, or diesel engines. Electric motors. Steam engines, fuel cell engines are examples of energy sources.
The fuel used to power most automobile engines comes from what source of energy?
nonrenewable source
What are the basic important components of IC engine?
The air intake system, carbourator or fuel injection system, combustion chamber, ignition source (spark or compression), and exhaust port or valve. This is very broad you could find much more by specifics looking into 4 stoke gasoline engines, 2 stroke gasoline engines, 4 stroke Diesel engines, and 2 stroke Diesel engines.
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 is the difference between two and four stroke engines?
In a 4-stroke engine, the steps (strokes) are:Intake stroke: During the intake stroke, the piston goes down from the top of the cylinder to the bottom, reducing the pressure inside the cylinder. It then draws a mixture of fuel and air into the cylinder through the intake port, ready for the compression stroke.Compression stroke: With both intake and exhaust valves closed, the piston goes back up to the top of the cylinder compressing the fuel-air mixture. This is what happens during the compression stroke.Power stroke: The compressed air-fuel mixture is then ignited by a spark. The pressure from the fuel-air mixture combustion drives the piston back down with humongous force, keeping the crankshaft turning. This is the power stroke phase, which is the main source of the engine's torque and power.Exhaust stroke: Finally, during the exhaust stroke, the piston again goes up and pushes the burned gas from the cylinder out the exhaust valve.Something worth mentioning is that the spark plug only fires once every two revolutions in a 4-stroke engine. Unlike the four stroke one, a two stroke engine has three strokes combined into one action, meaning the intake and exhaust are both integrated into the compression movement of the piston, therefore eliminating the need for valves. This is thanks to an inlet and exhaust port integrated into the wall of the combustion chamber.As the piston goes down from combustion, spent gasses are allowed to exit the chamber through the exhaust port. The air-fuel mixture is drawn through an inlet located lower in the chamber. As the piston rises again, it blocks off the inlet and exhaust ports, compressing the gasses at the top of the chamber. The spark plug fires and the process starts over.The spark plug fires on every revolution.=====A two stroke engine can produce twice the amount of power (and makes twice as much noise) than a four stroke engine of the same size. This is because it fires once every revolution, giving it twice the power of a four stroke, which only fires once every other revolution. Significantly, it also has a higher weight-to-power ratio because it is much lighter.Two stroke engines are simpler and cheaper to manufacture compared to four stroke engines because of their simpler design. Four stroke engines are longer lasting than two stroke engines that don't have a dedicated lubricating system. However, the spark plugs in a two stroke engine last longer than those in a four stroke engine.Four stroke engines are more fuel efficient and environmentally friendly when compared to two stroke engines that also create an unpleasant smell. Two stroke engines are responsible for much more pollution due to the combustion of the oil that has to be added to the fuel to lubricate the piston.
Does geothermal renewable?
Geo = earth and thermal = heat. Yes it is a renewable source of energy. Steam engines can be run of this type of energy which will essentially be clean burning fuel.
An engine that burns fuel in a chamber inside the engine is called?
It is called an Internal Combustion Engine(ICE for short) and covers a broad range of engine types not just the specified piston-cylinder engines asked about, but covers any kind of power source where fuel is burned with air(oxidised), inside a confined space and the resulting energy is used to turn a shaft through pistons and levers or turbines so that the energy can be used for a desired purposed. There are many different types of piston-cylinder engines but the most common ones in cars are four stroke petrol or diesel engines, less common are two stroke petrol and diesel engines. There are other types but of no real note to anyone except engineers and related disciplines.
During the 1840s and 1850s US factories were able to become more productive because?
steam engines began to be used as an energy source
What is the source of energy in a steam engine?
The energy source in a steam engine is the heat source that converts water into steam thus creating pressure. The heat source itself can be a coal, wood, gas or petroleum burner but can also be something different like a solar panel or a nuclear reactor (most nuclear reactors are themselves steam engines-generators).
When did coal replace wood as a chief energy source?
Coal began to replace the wood in the 1800s because the wood became scarce in some places. in the 1900s coal replace wood as a chief energy source because of its many used such as the fuel for steam engines which powered the many railroad engines popular during the period, and fuel for the steam turbines used in the production for electricity.
Are pistachios good for your health?
They are a rich source of energy with minerals, antioxidants and vitamins. They are rich in mono-unsaturated fatty acids like oleic acid, which prevent artery disease and strokes. The nuts are an excellent source of Vitamin C, Vitamin B6 and folates.
