Welding Precaution

Correct welding procedures are necessary in order to

avoid damage to the following components:

•   Electronic Control Module (ECM) on the engine

•   Clean Emissions Module (CEM)

•   Sensors

Illustration 1

g01143634

•   Associated components

Service welding guide (typical diagram)

Components for the driven equipment should also be

considered. When possible, remove the component

that requires welding. When welding on an engine

that is equipped with an ECM and removal of the

component is not possible, the following procedure

must be followed. This procedure minimizes the risk

to the electronic components.

5. When possible, connect the ground clamp for the

welding equipment directly to the engine

component that will be welded. Place the clamp as

close as possible to the weld. Close positioning

reduces the risk of welding current damage to the

engine bearings, to the electrical components, and

to other components.

1. Stop the engine. Remove the electrical power from

the ECM.

6. Protect the wiring harnesses from welding debris

2. Ensure that the fuel supply to the engine is turned

and/or from welding spatter.

off.

7. Use standard welding procedures to weld the

materials together.

3. Disconnect the negative battery cable from the

battery. If a battery disconnect switch is installed,

open the switch.

4. Disconnect all electronic components from the

wiring harnesses. Include the following

components:

System Operation

The governor uses the throttle position sensor to

determine the desired engine speed. The governor

compares the desired engine speed to the actual

engine speed. The actual engine speed is determined

through interpretation of the signals that are received

by the ECM from the engine speed/timing sensors. If

the desired engine speed is greater than the actual

engine speed, the governor injects more fuel in order

to increase engine speed.

Engine Governor

The ECM governs the engine. The ECM determines

the timing, the injection pressure, and the amount of

fuel that is delivered to each cylinder. These factors

are based on the actual conditions and on the desired

conditions at any given time during starting and

operation.

KENR9101

Electronic Troubleshooting

•   Injection timing

•   Fuel delivery

The flash file inside the ECM establishes certain limits

on the amount of fuel that can be injected. The  “FRC

Fuel Limit” is a limit that is based on the intake

manifold pressure. The “FRC Fuel Limit” is used to

control the air/fuel ratio for control of emissions. When

the ECM senses a higher intake manifold pressure,

the ECM increases the “FRC Fuel Limit” . A higher

intake manifold pressure indicates that there is more

air in the cylinder. When the ECM increases the

“FRC Fuel Limit” , the ECM allows more fuel into the

cylinder.

The  “Rated Fuel Limit” is a limit that is based on the

power rating of the engine and on the engine rpm.

The  “Rated Fuel Limit” is like the rack stops and the

torque spring on a mechanically governed engine.

The  “Rated Fuel Limit” provides the power curves

and the torque curves for a specific engine family and

a specific engine rating. All of these limits are

determined at the factory. These limits cannot be

changed.

Illustration 4

Typical example

Customer Parameters and Engine Speed

Governing

The desired engine speed is typically determined by

one of the following conditions:

•   The position of the throttle

A unique feature with electronic engines is customer

specified parameters. These parameters allow the

owner of the machine to fine-tune the ECM for engine

operation. Fine-tuning the ECM allows the machine

owner to accommodate the typical usage of the

machine and the power train of the machine.

•   The desired engine speed in Power Take-Off

(PTO)

Timing Considerations

Many of the customer parameters provide additional

restrictions on the actions that will be performed by

the ECM in response to input from the operator. The

“PTO Top Engine Limit” is an engine rpm limit that is

used by the ECM to limit the fuel during operation of

the PTO. The ECM will not fuel the injectors above

this rpm.

Once the governor has determined the amount of fuel

that is required, the governor must determine the

timing of the fuel injection. Fuel injection timing is

determined by the ECM after considering input from

the following components:

•   Coolant temperature sensor

Some parameters are intended to notify the operator

of potential engine damage (engine monitoring

parameters). Some parameters enhance fuel

economy (machine speed, engine speed limit, and

idle shutdown). Other parameters are used to

enhance the engine installation into the machine.

Other parameters are used to provide engine

operating information to the owner of the machine.

•   Intake manifold air temperature sensor

•   Intake manifold pressure sensor

•   Barometric pressure sensor

The ECM adjusts timing for optimum engine

performance and for fuel economy. Actual timing and

desired timing cannot be viewed with the electronic

service tool. The ECM determines the location of top

center of the number one cylinder from the signals

that are provided by the engine speed/timing sensors.

The ECM determines when injection should occur

relative to top center. The ECM then provides the

signal to the injector at the desired time.

Other ECM Functions for

Performance

The ECM can also provide enhanced control of the

engine for machine functions such as controlling the

cooling fan. Refer to Troubleshooting, “Customer

Specified Parameters” for additional information.

Fuel Injection

ECM Lifetime Totals

The ECM sends a high voltage signal to the injector

solenoids in order to energize the solenoids. By

controlling the timing and the duration of the high

voltage signal, the ECM can control the following

aspects of injection:

The ECM maintains total data of the engine for the

following parameters:
