Cylinder And Valve LocationThe Caterpillar 3406B (PEEC III) Truck Engine is an inline 6 cylinder arrangement with a bore of 137 mm (5.4 in) and a stroke of 165 mm (6.5 in) giving a total displacement of 14.6 liter (893 cu in) displacement. The firing order is 1,5,3,6,2,4 and the direction of crankshaft rotation is counterclockwise, as viewed from the flywheel. The engine is turbocharged and air-to-air aftercooled with direct fuel injection.The Programmable Electronic Engine Control (PEEC III) system was designed to provide electronic governing, automatic air-fuel ratio control, torque rise shaping, injection timing control, and system diagnostics. Additional benefits such as Cruise Control, Vehicle Speed Limiting, Low And High Gears RPM Limiting (progressive shift engine speed control), PTO Governor, Idle Shutdown Timer and Data Link provide for additional engine economy, driver comfort, and serviceability.A full range electronic governor controls the fuel injection pump output to maintain the engine rpm desired by the PEEC III system.Individual injection pumps, one for each cylinder, meter and pump fuel under high pressure to an injection nozzle for each cylinder. Electronic timing advance control provides the best fuel injection timing over the full range of engine speed.Starting The Engine
The PEEC III equipped engine may need to crank slightly longer than a mechanically governed engine, because some oil pressure is required for the electronic actuator to move the rack. The check engine light should be ON while the engine is cranking, but should GO OUT, within 10 seconds after the engine starts. At temperatures below 0°C (32°F), it may be necessary to spray starting fluid into the air cleaner inlet. If the engine fails to start in 30 seconds, release the starter switch. Allow the starter motor to cool for two minutes before using it again.Cold Mode Operation
The PEEC III system automatically idles the engine at 900 to 1000 rpm for the correct warm up time after a cold engine start [approximately less than 5°C (40°F)]. The PEEC III system will reduce the idle speed down to the programmed low idle, when the engine is warm enough to drive the truck. The PEEC III system considers the engine warm enough to drive when the engine response is acceptable, vehicle speed reaches 30 mph, or 15 minutes have expired. The time needed for the engine to reach the normal mode of operation is usually less than the time necessary for a walk-around-inspection of the vehicle.
A truck equipped with a 3406B PEEC III Engine should not be moved until it is out of the cold mode. If the engine is operated in the cold mode, rpm will be reduced to 1700 rpm and power will be noticeably reduced.
After Cold Mode is completed, the truck should be operated at low rpm and low power until normal operating temperature is
