INTRODUCTION AND PURPOSE :

This document is intended to provide necessary information for correct electrical & electronic application and installation of a C7 or C9 truck engine into an on-highway truck, bus, motor coach or vocational chassis. Caterpillar expects there will be some additions and modifications to this document as the engine program development continues, and as OEM requests for information not currently addressed are added. The information contained in this version of the document reflects the Caterpillar design for production C7 and C9 engines built with March 2004 software.

General Electronic Engine Operation
1.0 Engine Functions
1.1 Electronic Governing
Two engine speed range electronic governors are available for use. These electronic governors are selectable through a programmable parameter.
1.2 Fuel/Air Ratio Control
The control system has full authority over engine fuel delivery. The mechanical fuel/air ratio control is eliminated. Electronic control of the fuel/air ratio provides optimum performance with reduced emissions.
1.3 Injection Timing Control
Injection timing is varied as a function of engine operating conditions to optimize engine performance for emissions,
noise, fuel consumption, and drivability.
1.4 Torque Rise Shaping
Electronic controls provide increased flexibility to tailor the torque curve over a wide speed range.
1.5 Cold Mode Operation
When the engine is started with cold coolant, the engine will operate in “Cold Mode”. The engine will operate with reduced performance until the coolant temperature has warmed. The Caterpillar electronic service tool software will indicate when the engine is operating in Cold Mode. The C7 engine will operate in Cold Mode below 64 Deg C and the C9 engine will operate in Cold Mode below 40 Deg C.
