Ans. (c) Mixing of the fuel more thoroughly. Improved mixing had to be accomplished by imparting additional motion to the air, most commonly by induction-produced air swirls or a radial movement of the air, called squish, or both, from the outer edge of the piston toward the centre. Various methods have been employed to create this swirl and squish.

Squish in Four-Stroke Diesel Engines
Squish refers to the entry of air into the combustion chamber in four-stroke diesel engines. This process is essential for the proper functioning of the engine and helps in achieving better fuel efficiency and reduced emissions. Here's a detailed explanation of how squish works in diesel engines:
What is Squish?
Squish is the process of compressing the air-fuel mixture in the combustion chamber to create a turbulence that promotes better combustion. It is achieved by designing the combustion chamber in such a way that the piston, at the top of its stroke, comes very close to the cylinder head, compressing the air-fuel mixture between the two surfaces.
Why is Squish Important?
Squish is important for several reasons:
1. Better Combustion: The turbulence created by squish helps in better mixing of the air and fuel, leading to more complete combustion and reduced emissions.
2. Increased Efficiency: Squish helps in achieving more complete combustion, which translates into better fuel efficiency.
3. Reduced Knocking: Squish can also help in reducing engine knocking, which is caused by incomplete combustion.
How is Squish Achieved?
Squish is achieved by designing the combustion chamber with a specific shape and size. The shape of the combustion chamber is designed to create a space between the piston and the cylinder head that is small enough to compress the air-fuel mixture but large enough to allow proper combustion.
Conclusion:
In conclusion, squish is a critical process in four-stroke diesel engines that helps in achieving better fuel efficiency, reduced emissions, and reduced engine knocking. It is achieved by designing the combustion chamber with a specific shape and size that allows for the compression of the air-fuel mixture.
