In this diagram of the air induction and exhaust system, we seethe turbochargers (two), the air inlet system piping, theaftercooler, the air inlet plenum and elbows, the inletport and intake valves, the combustion chamber, the exhaust valves and the exhaust manifolds.
The location of the air inlet system, exhaust manifolds, turbochargers, piping, aftercooler and air plenum are all in the center of the vee of the block.
AIR INDUCTION AND EXHAUST SYSTEM
From the plenum chamber, the air goes throughpassages along the sides of the aftercooler, through aluminum elbows into the inlet ports, inlet valves and into the combustion chambers.
After the combustion or power stroke, the exhaust gases go out through the exhaust
valves, exhaust manifold, through theturbocharger turbine and goes out into the
This arrangement of the 3512 Engine has two turbochargers and an aftercooler.
The two turbochargers send air into the aftercooler air inlet.
The air inlet system, exhaust manifolds, turbochargers, piping, and aftercooler are all located in the center of the vee.
From left to right are the:
1. coolant manifold (left)
2. exhaust manifold (left)
4. rear lifting bail (eye)
5. exhaust manifold (right); and the
6. coolant manifold (right)
Watercooled manifolds and turbochargers are available on marine engines and are available as attachments on the industrial and generator sets.
On 3500 Engine Arrangements with water cooled exhaust manifolds, the coolant manifolds will be (combined with) the exhaust manifolds.
Here we see a generator set arrangement.

This is the rear of the engine. On the industrial generator set engines, the turbochargers are mounted on the rear of the engine.
Here we see the electrical connections for the solenoid of the emergency air shutoff valve.
The remote shutoff also activates the fuel shutoff solenoid to STOP engine.
This is the air inlet reset control of the emergency airshutoff. This is one style. There is another style.
