US Classification:
364424035
Abstract:
The system is provided for controllably monitoring data associated with operational characteristics of an engine. The system determines a maintenance activity requirement based on such characteristics. The system includes a plurality of transducers associated with the engine and connected to a programmable logic device. Signals from the transducers are continuously monitored and stored in an associated storage device. In response to predetermined sets of operational characteristics, an indication of when maintenance is due on the engine is produced by the logic device.
Automatic Elevated Idle Speed Control And Method Of Operating Same

Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
B60L 100
US Classification:
477 97
Abstract:
An automatic elevated idle speed control is disclosed for use with an internal combustion engine on a vehicle. The control includes an electronic controller connected with an engine speed determining means, and a sensor that determines the power requirements of a PTO device and produces a signal. The control automatically varies an engine speed command based on the signal.
Engine Speed Control And Method For Operating Same

Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
B60K 4102 B60K 4104 F16H 3700
US Classification:
477 73
Abstract:
A preferred embodiment of the present invention includes a power take off ("PTO") controller used on a vehicle. The controller includes a PTO on/off switch, a brake/clutch ignore switch, and a PTO set/resume switch connected to an electronic controller. The controller sets the engine speed command to a PTO default speed in response to the PTO on/off switch being in an on position. By placing the brake/clutch ignore switch in an ignore position, the vehicle operator can use the brake or clutch without affecting the PTO engine speed.
Fuel Delivery Temperature Compensation System And Method Of Operating Same

Assignee:
Caterpiller Inc. - Peoria IL
International Classification:
F23N 500
US Classification:
36443105
Abstract:
An engine control is provided for compensating the fuel delivery to an internal combustion engine as a function of the energy content of the fuel. The engine control includes a fuel temperature sensor connected to an electronic controller. A memory device including a standard fuel delivery map stored therein is connected to the electronic controller. The electronic controller calculates a compensated fuel delivery map as a function of the standard fuel delivery map and the fuel temperature, and the controller issues a fuel delivery command based on the compensated fuel delivery map.

Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
B60K 4106
US Classification:
477107
Abstract:
An elevated idle speed control is disclosed for use with an internal combustion engine on a vehicle. The control includes an electronic controller connected to a brake pedal sensor, a clutch pedal sensor, an engine speed determining means, a vehicle speed determining means, and a high idle mode selection means. The control permits a vehicle operator to select a desired high idle speed within a default high idle speed and a maximum high idle speed. The control permits the operator to select a high idle mode as a function of signals from said brake pedal sensor, said clutch pedal sensor, the engine speed determining means, the vehicle speed determining means and the high idle mode selection means.
Method For Controlling The Operation Of A Driver Circuit In Response To An Electrical Fault Condition

International Classification:
F02M 4702
US Classification:
123446
Abstract:
In one aspect of the present invention, a method for detecting an electrical fault condition of a driver circuit is disclosed. The driver circuit is used to energize an electrohydraulic device that regulates fluid pressure. The method detects the fault condition, and responsively switches from a normal fluid pressure control strategy to a fault mode fluid pressure control strategy in order to continue to control the fluid pressure during the fault condition.
Torque Limiting Power Take Off Control And Method Of Operating Same

Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
B60K 4120 F02D 3100
US Classification:
364426033
Abstract:
A control for limiting the torque output of an engine when operating in a PTO mode is provided. The control includes a microprocessor connected to a PTO on/off switch, a set/resume switch and a torque limit on/off switch. When the torque limit switch is in an on position, the microprocessor limits the maximum torque output to an operator programmed value. The operator can reprogram the torque limit value with a programming tool.
