What is up with these engines?

Why are they so small?

Why is the air inlet shaped that way?

What is between the air inlets?

I also noticed that the engine shrouds between the aircraft are shaped differently. Why does the one on the top picture on the inside shroud have that extra hole below the air intake?

Top photo. Inboard engine lower vent is for Air conditioning.
The other vents are for engine cooling. Notice the small top vents. Additional engine cooling. These engines obviously ran hot.
The lower photo the opening vent between the inlets is same engine cooling but a newer design.

Great looking airplane but it had problems with structural failures causing deaths. Square passenger windows caused problems for early hulls. I dont think the design ever recovered from the bad press after the break ups. I remember learning about the airplane in a&p school..
