Can anyone shed light on below answer;
Q. During a compression stroke in a four cycle engine. What describes best the position of piston and valves?
Ans 1. Piston rising to expel burnt gasses through exhaust valve
Ans 2. Inlet valve is open and sparking plug is parking to ignite air / fuel mixture
Ans 3. Piston falling and valve opens to pull in new air fuel mixture
Ans 4. Inlet and exhaust valves are used and piston is opening/gasing
Which of the above best describes??? :S
Many Thanks!
