Too much air results in a __________ air-fuel mixture that burns more slowly and hotter.

57% Answer Correctly

	lean
	rich
	light
	heavy

Solution

The stoichiometric ratio defines the proper ratio of air to fuel necessary so that an engine burns all fuel with no excess air. For gasoline fuel, the stoichiometric ratio is about 14.7:1 or for every one gram of fuel, 14.7 grams of air are required. Too much air results in a lean air-fuel mixture that burns more slowly and hotter while too much fuel results in a rich mixture that burns quicker and cooler.

The steering __________ transfers the motion of the steering gear output shaft to the steering arms that turn the wheels.

57% Answer Correctly

	column
	cylinder
	linkage
	arms

Solution

The steering linkage is a system of pivots and connecting parts between the steering gear and the control arms. The steering linkage transfers the motion of the steering gear output shaft to the steering arms that turn the wheels.

For inline cylinder arrangements in an engine, how are the cylinders numbered?

50% Answer Correctly

	sequentially from the front of the engine to the back
	sequentially from the back of the engine to the front
	alternating from the front of the engine to the back
	alternating from the back of the engine to the front

Solution

Inline cylinder arrangements number cylinders sequentially (1, 2, 3, ...) front to rear.

The distributor is responsible for:

71% Answer Correctly

	distributing power to the correct drive wheels
	utlizing battery power to start the engine
	timing the spark and distributing it to the correct cylinder
	recharging the battery

Solution

The distributor is driven by the engine's camshaft and is responsible for timing the spark and distributing it to the correct cylinder. The distributor cap contains a rotor that connects the ignition coil (and its high voltage) to the proper cylinder at the proper point in the stroke cycle.

Spark plugs receive current from the:

51% Answer Correctly

	distributor
	alternator
	ignition coil
	battery

Solution

Spark plugs receive current from the distributor and use it to spark combustion in the combustion chamber of a cylinder.
