Question 8
8.
Which of the following happens during intake?
The air-fuel mixture gets drawn in through intake valves and sent to the cylinders.
Both intake and exhaust valves are closed during the compression stroke. As pistons move up, the air and fuel mixture is compressed.
The spark plugs ignite the air-fuel mixture with a spark, creating a small explosion. This causes the pistons to get pushed down forcefully.
The final process in the cycle is the exhaust stroke. The exhaust valve opens, and gases created during combustion are expelled as the piston moves back up.
