I wish there were more of these engine part quizzes!

I have a few corrections/suggestions:

- "battery" should be accepted as well as alternator as both devices produce electricity.

- When looking for the word "coil" as the answer, I should be able to type in "ignition coil" and still have it accept it because the answer was part of the phrase I typed. This is how other quizzes on JetPunk work. When I typed in "ignition coil" it wouldn't accept it even though that is also a correct answer.

- For "the part that transfers power from the engine to the gearbox" you either need to specify a manual transmission, or you need to accept "torque converter" as another acceptable answer.

- The question about nitrogen isn't really an engine part, but I am just being nitpicky on this one.

- For "the largest casting in the engine", either "block" or "engine block" should be accepted. I have never heard it called a "cylinder block".
