2.

Air is burned in the combustion chamber.

True
False

Correct Answer

A. True

Explanation

In the given statement, it is stated that air is burned in the combustion chamber. This implies that combustion is taking place in the chamber, which typically involves the reaction of a fuel (in this case, air) with oxygen to produce heat and light. Therefore, the statement is true.

3.

Fuel is burned in the combustion chamber.

True
False

Correct Answer

A. True

Explanation

In a combustion engine, fuel is indeed burned in the combustion chamber. This is where the fuel-air mixture is ignited and combustion occurs, resulting in the release of energy that powers the engine. The combustion chamber is designed to facilitate the combustion process, ensuring efficient burning of the fuel and the generation of power. Therefore, the statement is true.

4.

What part keeps contaminants from getting to the combustion chamber?

Carbeurator
Fuel injector
Fuel lines
Capacitor
Fuel filter

Correct Answer

A. Fuel filter

Explanation

The fuel filter is responsible for keeping contaminants from reaching the combustion chamber. It is designed to remove impurities such as dirt, rust, and debris from the fuel before it reaches the engine. This helps to ensure that only clean fuel enters the combustion chamber, preventing any potential damage or clogging of the engine components.

5.

Most of today's cars use a carburetor to mix the fuel components into the combustion chamber.

True
False

Correct Answer

A. False

Explanation

Today's cars do not use a carburetor to mix the fuel components into the combustion chamber. Instead, they use a fuel injection system which directly injects fuel into the combustion chamber. This system is more efficient and allows for better control of fuel delivery, resulting in improved fuel economy and reduced emissions.

What critical adjustment is done by the mechanic to ensure the spark is ignited at the correct time?

Fuel flow
Spark size
Timing
Top dead center
Carbuerator

Correct Answer

A. Timing

Explanation

The critical adjustment that the mechanic does to ensure the spark is ignited at the correct time is timing. Timing refers to the precise moment when the spark plug fires in the engine's combustion cycle. It is crucial to adjust the timing correctly to optimize engine performance and fuel efficiency. By adjusting the timing, the mechanic ensures that the spark plug ignites the fuel-air mixture at the most optimal moment, allowing for efficient combustion and power generation in the engine.

7.

Which system controls the temperature of the engine?

Ignition
Heating
Coolant
Fuel

Correct Answer

A. Coolant

Explanation

The coolant system controls the temperature of the engine. Coolant, also known as antifreeze, circulates through the engine to absorb heat and prevent it from overheating. It transfers the heat to the radiator where it is dissipated into the air. The coolant system also helps to maintain the engine at an optimal operating temperature, preventing it from getting too hot or too cold, which can cause damage. Therefore, the coolant system is responsible for regulating and controlling the engine's temperature.

8.

What absorbs the heat from the engine?

Water
Radiator
Fan
Air
Anti-freeze

Correct Answer

A. Anti-freeze

Explanation

Anti-freeze is the correct answer because it is a coolant that absorbs heat from the engine. It circulates through the engine and absorbs the excess heat, preventing the engine from overheating. The anti-freeze then transfers the heat to the radiator, where it is dissipated into the surrounding air. This process helps to regulate the temperature of the engine and prevent damage due to overheating.

9.

What part moves the coolant through the engine?

Fan
Water Pump
Hoses
Force

Correct Answer

A. Water Pump

Explanation

The water pump is responsible for moving the coolant through the engine. It is a vital component that circulates the coolant, ensuring that it flows through the engine block, radiator, and other cooling system components. The water pump is typically driven by a belt connected to the engine, allowing it to pump the coolant and maintain proper engine temperature. Without a functioning water pump, the coolant would not be able to circulate effectively, leading to overheating and potential engine damage.

10.

The heater is part of the cooling system.

True
False

Correct Answer

A. True

Explanation

The explanation for the given correct answer is that the heater is indeed a part of the cooling system. While it may seem counterintuitive, the heater in a car is connected to the cooling system. The cooling system circulates coolant through the engine to regulate its temperature. A heater core, which is essentially a small radiator, is also connected to the cooling system. When the heater is turned on, the coolant flows through the heater core, and the heat from the coolant is transferred to the air that is blown into the car's cabin, providing warmth to the passengers. Therefore, the heater is an integral part of the cooling system.
