-alternators can now only be installed on gas engines
-gas engines consume small amounts of electricity while running (for ignition system, ECU, etc.
-gas engines will die if battery hits 0
	-> exception: small engines (1 cyl) don't require electricity to run (they use a magneto instead)
-plasma engines produce electricity while running (output comparable to truck alternator)
-changed minimum idle rate to 1% of full throttle
