Fuel Heaters
Fuel heaters prevent the waxing of the fuel, and the plugging of the fuel filters in cold weather. The engine does not dissipate enough heat to prevent waxing during cold-weather conditions. There are two types of fuel heaters that can be used: thermostatically controlled and self-adjusting. Heaters that are not thermostatically controlled can heat the fuel in excess of 65 °C (149 °F). High fuel temperatures can have the following effects:
Reduced engine efficiency
Fuel pump damage
Premature wearNote: Never use fuel heaters without some type of temperature regulator. Ensure that fuel heaters are turned OFF during warm-weather conditions.Fuel System Electronic Control Circuit
The injection pump, the fuel lines, and the nozzles that are used in the traditional Caterpillar diesel engines have been replaced with an electronically controlled, mechanically actuated electronic unit injector in each cylinder. A solenoid on each injector controls the amount of fuel that is delivered by the injector. An Electronic Control Module (ECM) sends a signal to each injector solenoid to provide complete control of the engine.There are two major components of the electronic control system that are necessary to provide control of the mechanical electronic unit injectors:
ECM
Personality module (storage for the ECM flash file)The ECM is the computer that is used to provide control for all aspects of engine operation. The personality module contains the software that defines the characteristics of the engine control. The personality module contains the operating maps. The operating maps define the following characteristics of the engine:
Horsepower
Torque curves
Engine speed (rpm)
Other characteristicsThe ECM, the personality module, the engine sensors, and the unit injectors work together to control the engine. Neither of the four can control the engine alone.The ECM maintains the desired engine speed by sensing the actual engine speed. The ECM calculates the amount of fuel that must be injected to achieve the desired engine speed.Fuel Injection
The ECM controls the amount of fuel that is injected by varying the signals that are sent to the injectors. The ECM sends a high-voltage signal to the solenoid to energize the solenoid. The injectors will inject fuel only while the injector solenoid is energized. By controlling the timing and the duration of the high-voltage signal, the ECM can control injection timing and the amount of fuel that is injected.The ECM sets certain limits on the amount of fuel that can be injected. The Fuel Ratio Control (FRC) is an adjustment which controls the amount of air and of fuel for emission control. This limit is based on the boost pressure. When the ECM senses a higher boost pressure, the ECM increases the FRC limit. Also, the Rated Fuel Position (RFP) is also a limit that is based on the horsepower rating of the engine. This limit is like the rack stops and to the torque spring on a mechanically governed engine. The RFP provides horsepower and torque curves for a specific engine family and for a specific engine rating. All of these limits are programmed into the personality module by the factory. These limits are
