International Classification:

B60R 4102

US Classification:

477 78, 123478, 123295

Abstract:

A method of generating a shift schedule and combustion mode schedule to optimize performance characteristics of a lean capable, multiple combustion mode engine with a time-variant after-treatment system is disclosed. The method comprises the steps of generating a lowest cost value for fuel economy and vehicle emissions as a function of an engine operating mode, wherein the engine operating mode is selected from a group consisting of a homogeneous stoichiometric mode, a homogeneous lean mode, and a stratified mode. The lowest cost value is stored in a shift schedule and combustion mode schedule along with the engine operating parameters that achieved the lowest cost value.

US Classification:

60285, 60274, 60277, 60276

Abstract:

An air/fuel control method for an engine including a NO sensor in operative relationship to a catalytic converter. The method comprises the steps of providing a base fuel signal related to a quantity of air inducted into the engine and generating a bias signal for biasing the base fuel signal towards a leaner air/fuel ratio. The output of the NO sensor is monitored to detect a predetermined exhaust gas NO value representing a predefined NO conversion efficiency. The base fuel signal is then modified as a function of the bias signal corresponding to the predetermined exhaust gas NO value to maintain the catalytic converter within a desired efficiency range. In one aspect of the invention, the process of detecting the edge of the NO conversion efficiency window is executed at predetermined time periods measured by the distance the vehicle traveled, or the elapsed time since last base fuel value modification.

International Classification:

F01L 1300

US Classification:

123 9015, 123 9011, 12340629, 123435

Abstract:

A valve timing system is provided for dynamically suppressing cylinder knock within an internal combustion engine. The engine is of the type including several cylinders , each having intake and exhaust valves. Valve timing system includes a controller , sensors , and actuators which selectively actuate valves in response to signals received from controller. Controller identifies knocking within one or more of cylinder(s) , and provides a modified control signal to the valve actuators which are associated with the identified cylinder(s). The modified control signal alters the duration in which the valves remain open, thereby suppressing knocking within the cylinder(s) without adversely effecting the vehicles fuel economy or emissions.

US Classification:

123685, 1231791, 12317921

Abstract:

In order to provide for reduced internal combustion engine exhaust emissions when cold starting an internal combustion engine, there is provided two methods and systems for cold starting an internal combustion engine, and one method and system for shutting down an internal combustion engine. The methods and systems are directed towards: (1) a preheating of a minimum of one thermally activated sensor within an internal combustion engine prior to cold starting of the internal combustion engine; (2) an autocranking of an internal combustion engine while metering fuel into the internal combustion engine and timing ignition within the internal combustion engine such as to reduce internal combustion exhaust emissions when cold starting the internal combustion engine; and (3) a phased shut down of fuel supply control followed by ignition source control when shutting down an internal combustion engine after operating the internal combustion engine.

US Classification:

701 34, 701 29, 701 35, 123505

Abstract:

A direct injection engine is coupled to a vacuum brake booster wherein vacuum created from engine pumping is used to supplement driver braking force. The brake booster is coupled through a check valve to the engine intake manifold. A method for estimating pressure in the brake booster uses various engine and vehicle operating conditions. A method for estimating operating parameters uses measured brake booster pressure. Further, a method for diagnosing degradation, or monitoring, a brake booster pressure sensor is based on engine or vehicle operating conditions. In addition, a method for diagnosing degradation in other vehicle and engine sensors uses measured brake booster pressure.

Abstract:

A system and method for controlling an internal combustion engine determine a catalyst gain based on an exhaust gas sensor positioned upstream relative to a catalyst and at least one exhaust gas sensor positioned downstream relative to at least a portion of the catalyst and use the gain to determine the condition or performance of the catalyst. The gain may be determined by modeling the catalyst as an integrator with an unknown gain and estimating the gain using a polynomial approximation. The gain is compared to an expected value or threshold associated with current operating conditions, such as catalyst temperature and/or mass air flow.
