Exam 1: Introduction to the Automobile

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 ___________________.

On a vehicle with automatic transmission, which of the following would MOST-Likely cause the rear wheels to rotate at different speeds as the vehicle goes around corners?

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 ____________________.

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

While discussing the four-stroke cycle, Technician A says that during the intake stroke, the piston is pulled down by the turning crankshaft, creating a vacuum above it. Technician B says this event occurs during the exhaust stroke. Who is right?

Which of the following would LEAST-Likely be found on a rear-wheel drive vehicle?

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

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

____ 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.

What is the relationship between the charging system and the ignition system? What is the role of the alternator?

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

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

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

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

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

What is the purpose of the ignition system and how does it operate?

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?

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

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