During idling the pressure in the inlet manifold is 20-25% of the atmospheric pressure.At suction stroke,the inlet valve opens and the product of combustion in the clearance volume expands in the inlet manifold,as the piston moves down to BDC,the gases along with fresh charge go into the cylinder.So to counteract the tendency of dilution and to get a ignitable mixture ,rich mixture is neccessary.
What else can I help you with?
What amount of power required to make the 2 stroke petrol engine to 4 stroke diesel engine?
you cant turn a 2 stroke into a four stroke. and i don't think you can run diesel in a 2 stroke
How many rotations of the crankshaft are required to complete each stroke of a two stroke cycle engine?
one rotation
Can side cam engine be installed in 4 stroke or 2 stroke engine?
sidecam engine cannot be installed in 2 stroke engine because in 2 stroke engine we have inlet & exhaust ports not valves... so when piston moves up and down it automatically opens the inlet and exhaust ports so it does not require any camshaft for opening of valves as it is required in 4 stroke engine
What amount of power required to make the 2-strke petrol engine to 4-stroke diesel engine?
Twice
How do you fix a 4 stroke dirt bike engine?
It would depend on what was wrong with the engine. More details are required.
What is the least number of valves required at the top of a four-stroke cycle engine?
two
What is the least number of valves required at the top of a four stroke cycle engine?
two
What the stage are two stroke and four stroke engine bothe vaves closed?
During the compression stage.
How is engine vacuum created?
During the intake stroke of each cylinder.
What occurs during up stroke of a 2 stroke cycle engine?
The upstroke of a two-stroke engine has only one function: compression. The downstroke is where power, then exhaust, then intake occur. This is the greatest animation I've seen for explaining a two-stroke engine: http:/www.animatedengines.com/twostroke.shtml
What are the four strokes to a four stroke engine?
The four strokes of a four-stroke engine are the intake, compression, power, and exhaust strokes. During the intake stroke, the engine draws in air and fuel. The compression stroke then compresses this mixture, followed by the power stroke, where the spark plug ignites the mixture, generating power. Finally, in the exhaust stroke, the engine expels the burnt gases from the combustion process.
Advantages of two stroke engine over a four stroke engine?
Explain the advantages of four-stroke engine over two-stroke engine
