QUIZ
Forum Discussion
It's quite obvious some posting negative comments about the quiz didn't read and/or comprehend the question or the 3 choices given. The quiz was about engines as in general but some seem to put their own nebulous into the questions asked. Basically shows their lack of documented formal education gained.
For instance: There are 4 distinct stroke cycles in a 4 stroke engine. 2 beginning at piston TDC and 2 at BDC. 2 distinct stroke cycles in a 2 stroke engine. The "fire in the hole" burn creating the expansion of gasses occurs only after the spark plug fires and occurs only in the power stroke which begins after piston has passed TDC from the compression stroke which is what was asked about in the quiz. Timing signal for the current to be sent to the spark plug to create the explosion is only relevant to and by the RPM the crankshaft is turning, not the piston's actual location. There's a time lapse that requires the signal/current setting required to be advanced before TDC! The power stroke only occurs AFTER piston reaches TDC.
