Exam 1: Introduction to the Automobile

What is the difference between a front-wheel drive and a rear-wheel drive vehicle?

All of the following are included in the engine's electrical system EXCEPT:

____ react to temperature, airflow, engine load, road speed, and oxygen content in the exhaust stream.

All of the following support the engine's operation EXCEPT:

____ is circulated by the water pump through water jackets in the engine's cylinder block. It carries heat to the radiator, where it can be carried away by the outside air.

Unlike diesel engines, gasoline engines do not have spark plugs or an ignition system because spark timing is controlled by the fuel injection system.

The purpose of the ____________________ is to reduce or eliminate any remaining pollutants in the engine's exhaust.

The ____________________ includes the suspension and also supports the engine and the car body.

Liquid gasoline does not burn.

During the four-stroke cycle, which event is LEAST-Likely to occur during the power stroke?

Older cars had heavy frames, but most cars are built today with what is known as a unibody design.

During a discussion about the lubrication system, Technician A says that, in theory, during a 1,000-mile trip a properly operating lubrication system will allow about as much wear between parts as occurs during the first 15 minutes of engine operation. Technician B says that the system will allow about as much wear between parts as occurs during the first 15 seconds of engine operation in the morning before oil has reached all of the engine's parts. Who is correct?

In a spark-ignition engine, gasoline is especially combustible when one part of it is atomized with about 15 parts of air.

On a manual transmission vehicle, the MOST-Likely cause of a change in torque would be:

Three types of fuel delivery systems have been used on automobile four-stroke cycle engines: carburetor, gasoline fuel injection, and ____________________.

Briefly describe the basic operating principle of a reciprocating gasoline engine.

The piston is sealed to the cylinder with ____________________ that slide against the cylinder wall as the piston moves up and down.

Air rushing through an engine's intake system is mixed with fuel on its way to the cylinders. This results in lower pressure in the intake manifold, which is known as ___________________.

What is the purpose of the exhaust system and what are its components?

Vintage engines have a fuel injection system that mixes fuel and air in response to the amount of air that flows through it.
