How does the fuel supply circuit work in a caterpillar?
How does the fuel supply circuit work in a caterpillar?
The fuel supply circuit is a conventional design for engines with electronic unit injection. A fuel tank (12) is used to store the fuel prior to use by the engine. A primary fuel filter/water separator (11) is placed into the fuel supply circuit in order to remove large debris from the fuel.
Where is the fuel transfer pump located in a caterpillar?
An outlet check valve is used in order to prevent pressurized fuel leakage back through the pump. The fuel transfer pump is located in the front of the engine. The fuel transfer pump is driven by the front gear train.
How does the ECM control the amount of fuel injected?
The ECM sets certain limits on the amount of fuel that can be injected. “FRC” is a limit 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.
How does the ECM work in a Caterpillar engine?
An Electronic Control Module (ECM) sends a signal to each injector solenoid in order to provide complete control of the engine. 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 in order to energize the solenoid.
What kind of fuel heater does caterpillar use?
The two types of fuel heaters that can be used: thermostatically controlled and self-adjusting. 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.
What kind of engine does a Caterpillar C18 have?
With plenty of options to keep the engine package size to a minimum, the Cat C18 is a fully-configurable engine giving owners t… Available SAE No. 1 power take off with optional SAE A, SAE B or SAE C power take off drives. Engine power can also be taken from the front of the engine with optional attachments. (Tier 4 Final, Stage V).
What is the Def capacity of a Cat C18?
With a DEF capacity of 93.7 liters and 5,000-hour service intravals, the Cat C18 also features transparent regeneration technology giving owners the power to stay more productive—when its needed the most. Whether you own a fleet of machines or even just one, it’s important to keep lifetime costs of the engine low.
