What happens in the upstroke of the piston in the crankcase in a four stoke engine?

On compression the air is compressed, and on exhaust it is forced out of the cylinder.

What is the function of piston rings in engine?
Isolate the combustion chamber above the piston from the crankcase below the piston, so that the pressure does not blow-by the piston into the crankcase. Also they ensure an even spreading of crankcase oil along the walls of the cylinder to prevent wear. They also provide improved thermal contact from the piston to the cylinder walls, which are cooled by the cooling system.
Component of internal combustion engine?
There are many components but the most noteable are the block, head, crankcase, cylinder, piston, piston rod, crank shaft, camshaft, and flywheel.
Where is the crankcase located on a 1997 Pontiac Sunfire?
Generally speaking, the crankcase is the lower part of the engine. It's where the crankshaft connects to the piston rods. If you drop the oil pan and look inside, you'll be looking at the crankshaft and the bottoms of the piston connecting rods.
What do you mean by engine blowby in automobile section?
Blowby is a condition to where you have excessive pressure in the crankcase of an engine usually from worn piston rings. A faulty PCV system can also cause excessive engine blowby.
Why does your Briggs and stratton lawn mower blow blue smoke and oil?
Worn piston rings. Incorrect weight engine oil. Gasoline mixed with engine oil. Crankcase overfilled with engine oil.
What are the basic parts of an engine?
engine block, piston, cylinder head, cylinder liner, camshaft, crankshaft, valves, crankcase/sump, inlet manifold, exhaust manifold, cylinder head cover
Where is the jug on a motorcycle?
The 'jug' refers to the cylinder part of the engine, it's between the crankcase and the cylinder head. It's the section that the piston travels up and down in.
Why do you get so much oil blow-back on your 60 series Detroit engine?
Hole in one of the piston allowing combustion pressure into the crankcase.
In a two stroke piston port engine the transfer tube is used to transfer fuel from the?
B: from the crankcase to the top of the combustion chamber. good luck on test :->
What is the working principle of crankcase scavenged two stroke engine?
In crankcase scavenging , the crank case compression of air (in c.i engine)or air fuel mixture (in s.i engine) accrues in the crank case.The medium is introduced at atmospheric pr. into the space below the piston through a one way valve.The power stroke of the piston compresses the medium as well as pushed the compressed medium through a inlet port into the combustion chamber.
What is the PCV valve on your 96 dodge avenger and what does it do?
PCV stands for Positive Crankcase Ventilation, is a valve that releases air by turbulance created inside the engine when the crankshaft and piston are turning while engine is running.
Main difference between a steam engine and an internal combustion engine?
It's complicated but I'll summarize. An internal combustion engine sucks in air and fuel when the piston goes down, compresses it on the upstroke and spark plug ignites the fuel/air mix causing the fuel to expand pushing the piston back down creating the force. A steam engine uses pistons and valves as well but the pressure comes from an external boiler and the steam pressure piped into the cylinder pushes the piston up and down.
