In some examples, the engine has at least a cylinder and a compression device coupled to an intake of the engine, and the method includes, during engine re-start operation of an engine idle-stop condition, commencing combustion in the cylinder from a non-combusting condition, the combustion in a two-stroke combustion cycle of the cylinder. However, in some examples, at least partially electrically powered boosting operation may also be used to extend the two-stroke operation during a start. | 05-10-2012 |

20090260596 | IGNITION AND FUEL SHUTOFF FOR ENGINE - A carburetor assembly includes a carburetor, a fuel supply valve, a valve member and a normally open switch. The fuel supply valve is coupled to the carburetor housing and is fluidly connected to the carburetor. The fuel supply valve includes a lever pivotable between first and second positions. The valve member is configured to move in response to the lever such that fuel is allowed to flow to the carburetor when the lever is in the first position and fuel is not allowed to flow to the carburetor when the lever is in the second position. The normally open switch is adjacent the fuel supply valve and includes a switch actuator. The lever is configured to engage and release the switch actuator to move the switch actuator between a non-actuated position and an actuated position respectively when the lever moves between the first and second positions. | 10-22-2009 |

20110265761 | Method and related system of dithering spark timing to prevent pre-ignition in internal combustion engine - Methods of mitigating the occurrence of a low-speed pre-ignition event in a multi-cylinder internal combustion engine ( | 11-03-2011 |
20110283971 | METHOD FOR MANAGING TRANSITIONS IN INTERNAL COMBUSTION ENGINES WITH COMBUSTION PHASING - A combustion mode transition control for controlling a transition between a homogeneous-charge compression-ignition (HCCI) combustion mode and a spark-ignition (SI) combustion mode includes slowly transitioning intake and exhaust camshafts from initial phase settings corresponding to one of the HCCI and SI combustion modes to target phase settings corresponding to the other of the HCCI and SI combustion modes. An ignition spark timing and an injected fuel mass are coordinated with the transitioning of the intake and exhaust camshaft phase settings to substantially maintain engine load continuity during the transitioning of the intake and exhaust camshaft phase settings. | 11-24-2011 |
20120222653 | SPARK IGNITION INTERNAL COMBUSTION ENGINE - An internal combustion engine provided with a variable compression ratio mechanism able to change a mechanical compression ratio and a variable valve timing mechanism able to control a closing timing of an intake valve. An actual compression ratio and ignition timing in a predetermined standard state after completion of engine warm-up are stored in advance as a reference actual compression ratio and a reference ignition timing. When the engine temperature is low or the intake air temperature is low, at the time of engine high speed operation, the actual compression ratio is made to increase over the reference actual compression ratio, while at the time of engine low speed operation, the ignition timing is made to advance over the reference ignition timing. | 09-06-2012 |
20130047956 | CONTROL SYSTEM AND METHOD FOR PREVENTING STOCHASTIC PRE-IGNITION IN AN ENGINE - A control system for an engine includes a spark module and a fuel module. The spark module advances spark timing of a cylinder R degrees past a spark limit for N consecutive cylinder firing events, and retards spark timing of the cylinder past the spark limit for M consecutive cylinder firing events after the N consecutive cylinder firing events. The fuel module supplies a rich fuel-air charge to the cylinder for the M consecutive cylinder firing events. According to the system, R is a real number greater than zero, N and M are integers greater than zero, and the spark limit is a control value used to limit an amount of spark advance to prevent spark-knock. A method for controlling an engine is also provided. | 02-28-2013 |
20130167803 | MULTI-CYLINDER INTERNAL COMBUSTION ENGINE AND METHOD FOR OPERATING SUCH A MULTI-CYLINDER INTERNAL COMBUSTION ENGINE - A linearly aligned four-cylinder internal combustion engine system operated in a 1-3-4-2 sequence, comprising a cylinder head connected with a cylinder block wherein each cylinder has at least one exhaust port to discharge exhaust gasses via an exhaust gas discharge system, for which an exhaust gas pipe is connected at each exhaust port; wherein the exhaust gas pipes of the cylinders that merge in stages into a common exhaust gas pipe and the exhaust gas discharge system emerges outside of the cylinder head. Thus exhaust gas from consecutive ignitions in adjacent cylinders is separated for a distance throughout the engine head to reduce mutual influencing in adjacent cylinders with consecutive ignitions. | 07-04-2013 |
