How fuel is burnt in engine?
Fuel is mixed with air, compressed then ignited.
What is burnt in the car engine to release energy for the car to move. Can it burn without air or oxygen?
It's a mixture of fuel and air. It can't be done without oxygen - that's one of the elements needed for fire,
How is biofuel used to heat water?
The Bio-fuel is burnt in air to heat water.
Does aircraft fuel pollute the environment?
Yes. It's a fossil fuel, burnt and released into the air w/o any cleaning.
What does a cars manifold do?
The intake manifold routes the fuel/air mixture to the cylinders or just the air on a modern fuel injected engine. The exhaust manifold routes the burnt fuel gases out of the engine into the exhaust system.
What force sends a rocket to space?
The thrust, which is the force on the rocket due to air. When the fuels are burnt, air (including burnt fuel) is pushed downwards. From Newton's third law, the air exerts an upward force of equal magnitude on the rocket.
Why engine need air?
Air is fed into the cylinder - to mix with fuel. The fuel cannot burn without air !
Why is carbon monoxide more likely to be formed in engines than if the fuel was burnt in the open air?
When fuel is burnt, the carbon bonds with oxygen. If enough oxygen is available this will become carbon dioxide. In engines, less oxygen is available, and so burning the fuel is more likely to form carbon monoxide than in open air.
Is fuel pollution a type of air pollution?
Pollution from burning fuel in vehicles contributes to air pollution, yes. There are two kinds of emissions:# Exhaust emissions: carbon dioxide and water vapor (greenhouse gases), as well as dangerous gases such as carbon monoxide, oxides of nitrogen, hydrocarbons and particulates. # Evaporative emissions: vapors of fuel which are released into the atmosphere, without being burnt.
What is the function of engine valves in car?
Engine cylinder head valves admit the air/fuel mixture and release the burnt gases.
Why is fuel burnt?
They burn fuel so that they can make petrol.
Why thus the compression ignition engines produce fewer emissions?
Compression ignition engines can easier be made to run lean, meaning they'll havemore air than what's actually needed for the amount of fuel that's present. With excess air,(and higher temperature) it's easier to get more of the fuel burnt. With more of the fuel burnt, there's less unburnt fuel being vented as exhaust, meaning fewer emissions.
