4. BASIC SYSTEM INFORMATION
[1] FUEL SYSTEM
KUBOTA FUEL SYSTEMS
Kubota LSI engines use EControls fuel system. In
this section of the manual, Kubota fuel system will be
explained further to provide the technician the ability to
understand how each system operates and the general
layout of each system. A typical installation schematic
has been included to identify where in the system the
components are located, and how the component
communicates to other fuel system components, and the
EControls ECM.
FUEL METERING SYSTEMS
In all cases where EControls has supplied the fuel
metering system for Kubota, EControls has designed the
system for peak engine performance, durability, precise
fuel metering and control of the exhaust emission. Each
design has been tested and developed in conjunction
with Kubota. When servicing an EControls system, you
should always follow the prescribed service instructions
and procedures, to repair the engine fuel system. When
replacing parts within the fuel metering system you
should use only Kubota replacement parts. Failure to do
so may result in improper performance, an unsafe
conditions, and lack of emissions control.
ENGINE CONTROL MODULE
Kubota fuel system will utilize an EControls Engine
Control Module (ECM), to control fueling and control
emissions output, in the exhaust. In some cases the
ECM provides signal output to the vehicle instrument
panel. The ECM will utilize signal inputs, from the engine
sensors, to control the fuel metering and speed control,
while the engine is running. As well, the ECM will provide
diagnostic control, over the fuel system.
The diagnostics within the ECM, continually monitor
the fuel system performance, by measuring sensor
voltage, and if the ECM determines that a sensor value
has exceeded the high or low threshold value, the ECM
will make changes in the fuel metering system operation,
to protect the engine fuel system. These changes were
developed during the EControls calibration activities,
and during the design of the system. To assist the
technician, in determining the fault condition, in the
EControls fuel system, Diagnostic Trouble Codes (DTC),
are used, to identify the fault conditions. These fault
codes can be identified, by using the EControls Global
Control Platform laptop diagnostic tool (GCP). To
determine fault codes and corrective action to be taken,
the technician will use the GCP and the Diagnostic
Trouble Code section, of this manual, to determine the
root cause of the failure, the effective changes in the
EControls fuel system, as well as what repairs must be
made, to correct the fault in the fuel system.
