| 20090090318 | METHOD FOR CONTROLLING AIR-FUEL RATIO FOR AN ALTERNATING VALVE ENGINE - A method for controlling the air-fuel ratio of an internal combustion engine operating with alternating intake valves is presented. According to the method, engine air-fuel ratio can be adjusted by changing valve timings or fuel during a cylinder cycle. | 04-09-2009 |
| 20100012088 | ENGINE CONTROL INCLUDING KNOCK COMPENSATION - Systems and methods are described, including one example method of controlling an engine having a cylinder with at least one valve operated by a variable valve mechanism (VVM) having a sensor coupled to the valve, the method comprising: adjusting at least one operating parameter in response to an indication of detonation of a combustible mixture in the cylinder, the indication based on the sensor coupled to the valve. | 01-21-2010 |
| 20100180840 | METHOD FOR CONTROLLING AIR-FUEL RATIO FOR AN ALTERNATING VALVE ENGINE - A method for controlling the air-fuel ratio of an internal combustion engine operating with alternating intake valves is presented. According to the method, engine air-fuel ratio can be adjusted by changing valve timings or fuel during a cylinder cycle. | 07-22-2010 |
| 20110000463 | FUEL SYSTEM WITH ELECTRICALLY-CONTROLLABLE MECHANICAL PRESSURE REGULATOR - A method for operating an engine direct injection fuel system is provided. The direct injection fuel system includes a mechanical fuel pressure regulator that has a spring actuatable by an electric motor. The method includes adjusting a preload of the spring by operating the electric motor to adjust a set-point fuel pressure from a first set-point fuel pressure to a second set-point fuel pressure in response to an operating condition, and maintaining the preload of the spring mechanically when the electric motor is not operating. | 01-06-2011 |
| 20110071746 | ASSISTED DIRECT START ENGINE CONTROL FOR ENHANCED LAUNCH PERFORMANCE - A system and method for controlling an internal combustion engine include anticipating vehicle launch in response to vehicle position relative to a traffic stream and controlling automatic restart and shut down in response to an anticipated vehicle launch to prevent an automatic engine shut down or to initiate an automatic engine restart. Embodiments include determining vehicle position and traffic position using GPS coordinates. Automatic restart may be initiated in response to movement of a forward vehicle away from the vehicle or in response to a signal from a traffic control device, for example. Automatic shutdown may be inhibited in response to movement of a forward vehicle in cross traffic, in response to a turn indicator being active, or in response to wheel angle, for example. | 03-24-2011 |
