A request for some information â€¦

Here's a message from Martin Nowak:

I'm trying to uncover the history of these old vehicles. Does anyone know which units they belonged to or what their original purpose was? One of the engines is currently in Chicago, located along Archer Avenue, and the ambulance can be found behind the Countryside Police Station. Any information you might have would be greatly appreciated.

Thank you,

Martin Nowak

Cylinder Liner For NISSAN
The Cylinder Liner is a cylindrical part that is placed in the cylinder block hole of the body and is secured by the cylinder head. The piston reciprocates in its inner hole and is cooled by cooling water outside.

The functions of the cylinder liner are:

1. Together with the cylinder head and piston, it forms the cylinder working space.

2. The cylinder liner of the cylinder piston diesel engine is the lead of the reciprocating movement of the piston, which is subjected to the side thrust of the piston.

3. The heat of the piston assembly and itself is transferred to the cooling water to make the working temperature appropriate.

4. The cylinder liner of a two-stroke diesel engine is arranged with an air port, which is opened and closed by a piston to realize gas distribution.

Engine requirements for cylinder liner:
The cylinder liner should have sufficient strength, stiffness and heat resistance, and should also have good wear resistance. There should be good lubrication and cooling in the work.
