What is internal-combustion engine?
An internal combustion engine is one where a gas/air mixture is ignited and burned in a closed cylinder, and forces a piston to move. In other words, all piston engines in cars, trucks, bikes aircraft.
What is an combustion engine is about?
Combustion means fire. A combustion engine means that an engine puts a fire in a particular place. A steam engine places a fire underneath a boiler. The water in the boiler expands and drives a piston or turbine. That is attached to a drive shaft and drives the wheels or generator. In a jet engine, the combustion occurs in the combustion chamber. That makes the gas expand and the expanding gas goes out the rear of the engine and pushes the airplane forward. However, I suspect you are interested in the Internal Combustion Engine. In an Internal Combustion Engine, Gasoline or other fuel is mixed with air in the intake manifold. A valve opens. A piston comes down. When the piston goes down, the fuel-air mixture is sucked into the cylinder. Then the valve closes. The piston pushes the mixture up compressing and heating the mixture. When the piston reaches the top, a spark plug sends a spark into the mixture. It burns. It pushes the piston down. That is called the power stroke. It sends power to the crankshaft and to the wheels. Then a valve opens. The piston comes back up and pushes the burned gas out of the cylinder into the exhaust manifold. That is how gasoline becomes useful energy.
What causes ignition to occur in a diesel engine?
When the piston compresses the fuel-air mixture, the spark ignites it, causing combustion
During which stage of engine operation does the burning mixture of air and fuel force the piston downward?
This is during "combustion" which is the "power" stage of the operation.
What type of reaction powers a car?
The combustion of the air and fuel mixture in the combustion chamber gets lit on fire by the spark plug and and pushes the piston down which gets it moving faster and makes it work harder to get the piston back up to TDC (top dead center)
What is the most strokes in a car engine?
Internal combustion engines are 4 stroke: 1) Intake (air/fuel mixture is introduced to combustion chamber) 2) Compression (piston rises to compress this mixture) 3) Ignition (spark is introduced to compressed fuel/air mixture ignited same) 4) Exhaust (waste product is expelled from combustion chamber)
What does the internal combustion engine work?
rising piston compresses air/fuel mixture , then ignited at top, heat raises pressure, pressure on piston crown creates force, force over stroke = work
What does a piston do in a combustion engine?
A piston is attached to a piston rod in a combustion engine. It compresses the air in the cylinder block and that air ignites when fuel is injected into the block, giving the car power.
What is combustion in vehicle?
when the piston and valve meet the fuel is compressed and with spark you have combustion
How does piston get power to rotate the crankshaft?
From the combustion of air and fuel in the combustion chamber.
What is an internal-combustion engine?
An internal combustion engine is an engine that uses air, fuel, and spark to create the power to move. A perfect air-fuel mixture is pulled into the cumbustion chamber, its compressed by the piston, and once its compressed the spark plug ignites the air-fuel mixture and the process is completed.
The source of thermal energy in an internal combustion engine?
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.
