How much to you know about engine technology

The answers to questions 7 and 13 are wrong.

Spark plugs fire on the compression stroke, several degrees BTDC, just before the power stroke begins at TDC.

Pistons are connected to connecting rods, not the crankshaft.

Got 28 of 30.

Some engine timing is set for 0 degrees tdc, but you're right, technically they normally fire during the compression stroke.

Given the other answers, crankshaft is the most correct answer. :)
