Filed:

Oct 14, 2004

Appl. No.:

10/965416

Inventors:

Victoriano Ruiz - Brighton MI, US
Douglas J. Babcock - Dexter MI, US

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F02D 23/00
F02B 33/44
F01N 3/00

US Classification:

60602, 606051, 60276, 60285, 60298, 60284, 60274

Abstract:

A turbine temperature control (TTC) system for regulating operation of an engine to control a temperature of a forced air induction device. The system includes a sensor that is responsive to an exhaust gas temperature and that generates a signal. A control module determines a temperature based on the temperature signal and compares the temperature to a threshold temperature. The control module regulates operation of the engine to decrease the temperature when the temperature exceeds the threshold temperature.

F02D 11/10

US Classification:

701103, 123350, 123399, 606051, 701110

Abstract:

An engine system includes an engine having an intake manifold and a turbocharger that supplies compressed air to the intake manifold. An engine control module calculates a desired pre-throttle pressure of air before the throttle and calculates a desired manifold air flow into the engine. The engine control module determines a desired pre throttle pressure area based on the desired air per cylinder, desired manifold pressure and RPM and generates control signals to control the engine with the turbocharger.

International Classification:

F02D 41/14
G06F 14/48

US Classification:

123399, 701103, 701115

Abstract:

An engine control system comprises a predicted airflow module, a first actuator determination module, a first desired air module, and an actuator position module. The predicted airflow module determines a predicted engine airflow based on a desired torque. The first actuator determination module determines a first engine actuator value based on the predicted engine airflow. The first desired air module selectively determines a first desired engine air value based on the first engine actuator value and the desired torque. The actuator position module determines a desired engine actuator value based on the first desired engine air value.

B60W 20/00

US Classification:

701 22, 180 65275, 180 65265

Abstract:

A hybrid controller for controlling a hybrid vehicle is set forth. The hybrid vehicle has an engine, an electric motor and an engine controller determining a crankshaft torque. The hybrid controller includes an optimization module determining an electric motor torque, determining an engine torque and communicating the engine torque from the hybrid controller to the engine controller. The hybrid controller also includes a motor control module controlling the electric motor based on the electric motor torque.

S. Miller Weisman - Farmington Hills MI

Assignee:

Detroit Diesel Corporation - Detroit MI

International Classification:

B60K 3104
F02D 1304

US Classification:

123322

Abstract:

A method for comprehensive integrated control of a compression-ignition internal combustion engine having integral fuel pump-injectors utilizing an electronic control unit is disclosed. The control strategy integrates various functions of engine control including fuel delivery, cooling fan control, engine speed governing and overspeed protection, engine braking, torque control, and vehicle speed diagnostics and control. Cooling fan control is integrated with vehicle speed diagnostics and control as well as fuel delivery to provide an integrated cruise control function which incorporates engine braking. The method also includes improved control over the various engine speed governors while improving idle quality by balancing the power delivered by each of the engine cylinders when at idle. The integrated torque control employs functions to reduce NOx emissions and noise utilizing adaptive fuel delivery timing and a split injection strategy.

US Classification:

701 36

Abstract:

A method for comprehensive integrated control of compression-ignition internal combustion engine, wherein the control strategy integrates various functions of engine control with cooling fan control, and wherein the cooling fan control automatically ramps down cooling speed for multi-speed cooling fans whenever monitored engine conditions effecting cooling fan operation dictate transition of the multi-speed cooling fan from a high speed to an off condition.
