What are the two most commonly used internal combustion engines?
Gasoline and Electric
Diesel and Electric
Gasoline and Diesel
Hybrid and Electric
Why are gasoline engines less noisy compared to diesel engines?
Due to smoother combustion process
Due to better structural design
Due to better fuel economy
Due to higher compression ratio
What is the main difference in the combustion process between gasoline and diesel engines?
Gasoline engines have a pre-mixed fuel and air while diesel engines mix during combustion
Gasoline engines have a controlled combustion process while diesel engines have uncontrolled combustion
Gasoline engines have a fuel injector while diesel engines use a spark plug
Gasoline engines have a higher compression ratio than diesel engines
Why is it not advisable to put gasoline in a diesel engine?
It will improve fuel economy
It will cause detonations due to highly compressed air
It will lead to smoother combustion
It will not cause any firing
What is the reason behind diesel engines having better fuel economy compared to gasoline engines?
Due to smoother combustion process
Due to higher compression ratio
Due to better structural design
Due to pre-mixed fuel and air
What happens if atomized diesel is sprayed into high temperature air?
Spontaneous combustion occurs
Smooth combustion occurs
No combustion occurs
Detonations occur
Why do diesel engines require a more rugged structural design than gasoline engines?
Due to smoother combustion process
Due to better fuel economy
Due to uncontrolled combustion process
Due to higher compression ratio
What is the main difference in the way fuels burn between gasoline and diesel engines?
Diesel is less volatile than gasoline
Gasoline readily evaporates while diesel does not properly mix with air
Diesel readily evaporates while gasoline does not properly mix with air
Gasoline is less volatile than diesel
What is the purpose of a fuel injector in diesel engines?
To mix fuel and air before combustion
To achieve a high compression ratio
To reduce excessive vibration and noise
To initiate combustion
Why can diesel engines achieve a good compression ratio without the risk of self-ignition?
Due to compressing only the air
Due to pre-mixed fuel and air
Due to better structural design
Due to smoother combustion process
What is the main reason why gasoline engines are preferable for lightweight applications?
Due to higher compression ratio
Due to less noise and vibration
Due to better fuel economy
Due to smoother combustion process
What is the outcome of putting gasoline in a diesel engine?
Improved fuel economy
No firing
Detonations
Smooth combustion
What is the outcome of putting diesel in a gasoline engine?
Improved fuel economy
No firing
Detonations
Smooth combustion
Why does combustion in a diesel engine turn out to be an uncontrolled process?
Due to combustion beginning anywhere in the combustion chamber
Due to high compression ratio
Due to better fuel economy
Due to smoother combustion process
What is the main reason behind the excessive vibration and noise in diesel engines?
Due to smoother combustion process
Due to better fuel economy
Due to uncontrolled combustion process
Due to higher compression ratio
