The Caterpillar 3406 Diesel Truck engine is direct fuel injected, turbocharged and an air-to-air aftercooler arrangement (ATAAC). The cooling system consists of a gear driven centrifugal pump, with one thermostat which regulates the engine coolant water temperature, an oil cooler and an OEM radiator incorporating a shunt system.The engine lubricating oil, which is both cooled and filtered, is supplied by a gear-type pump. Bypass valves provide unrestricted flow of lubrication oil to the engine parts when oil viscosity is high, or if either the oil cooler or the oil filter elements should become plugged.Engine efficiency, efficiency of emission controls and engine performance depend on adherence to proper operation and maintenance recommendations, and the use of recommended fuels and lubrication oils.Electronic Engine Control (if equipped)
The programmable electronic engine control is designed to provide electronic governing, automatic air-fuel ratio control, torque rise shaping, injection timing control and system diagnostics with the capability for future expansion.Other benefits such as improved cold starting capability, tamper diagnostics, cruise control, vehicle speed limiting, low and high gears engine rpm limiting (progressive shift engine speed control), PTO governor, ATA data link (SAE J1587) and an Engine Monitoring Package.The fuel system is mechanically actuated and electronically controlled combining the pumping, electronic fuel metering and injecting elements to produce higher injection pressures.High injection pressures help to reduce fuel consumption and particulate emissions.Individual injection pumps, one for each cylinder, meter and pump fuel under high pressure to an injection valve for each cylinder.A full range electronic governor controls the fuel injection pump output to maintain desired engine rpm. The governor functions like the Caterpillar mechanical governor in the mid-range, but includes additional features. These include programmable isochronous low idle and 20 to 200 rpm governor overrun.Automatic timing advance provides the best fuel injection timing over the full range of engine speed. The injection timing is varied as a function of engine operating conditions.This optimizes the engine's performance for starting, emissions, noise, fuel consumption and driveability.The Electronic Engine Control has built-in diagnostics to assure that all components are functioning and operating properly.In the event of a system component deviation from programmed limits, the operator will be alerted to the condition by a dashboard mounted CHECK ENGINE/DIAGNOSTIC lamp.A Caterpillar service tool or cruise control switches (if equipped) are needed to read the numerical code of the diagnostic flash code. There are three types of diagnostic codes; active (fault), logged and event. These codes are logged and stored in the system memory.Multi-Torque Rating (if equipped)
Multi-torque ratings provide for additional torque as engine load increases. This feature provides higher torque levels and better driveability while in the top gears ONLY. The engine electronics are able to determine when
