| 123334000 | Engine speed reduction by partial or complete omission of the ignition | 8 |
| 20090159042 | Control Apparatus for an Engine - A control apparatus for an engine including a unit for retarding an ignition timing from an MBT by a predetermined value or more during cranking at engine starting or during a period from a first combustion up to an idling engine speed. | 06-25-2009 |
| 20090183711 | Fuel Supply Apparatus and Fuel Supply Method of an Internal Combustion Engine - A high-pressure pump ( | 07-23-2009 |
| 20100199949 | HAND-HELD ENGINE-POWERED TOOL - When throttle lever is pulled with the rotation lock member of the engine-powered tool in a state in which rotation of rear handle is permitted, the electrode terminal provided on the rotation lock member and the electrode terminal provided on throttle lever contact each other. As a result of this contact, the two output terminals of the engine generator are short-circuited, the supply of electric power to the ignition device from the engine generator is stopped and the supply of electric power from the ignition device to sparkplug in the engine is stopped. Through this, operation of the blade is prevented when rotating rear handle. | 08-12-2010 |
| 20130333663 | INTERNAL COMBUSTION ENGINE FEATURING PARTIAL SHUTDOWN AND METHOD FOR OPERATING AN INTERNAL COMBUSTION ENGINE OF THIS KIND - Systems and methods are provided for an engine wherein one group of cylinders is active and a second group of cylinders is switchable, such that under low loads the second group of cylinders is deactivated, and under high loads the second group of cylinders is activated. Following deactivation of the second group of cylinders a throttling element in an intake line for the second group of cylinders is gradually closed. The closing of the throttling element may reduce pumping losses and thus increase engine efficiency. | 12-19-2013 |
| 20160102616 | METHOD FOR CONTROLLING TRANSITIONS IN A VARIABLE DISPLACEMENT ENGINE - Methods and systems are provided for controlling transitions between engine operating modes in a four-cylinder engine. One method includes transitioning engine operation between two-cylinder, three-cylinder, and four-cylinder modes wherein the transitioning includes a sequence of firing events such that successive firing events are separated by at least 120 crank angle degree intervals. | 04-14-2016 |
| 20160131058 | MULTI-LEVEL SKIP FIRE - In one aspect, a method for controlling operation of an internal combustion engine is described. The engine is operated in a skip fire manner such that selected skipped working cycles are skipped and selected active working cycles are fired to deliver a desired engine output. A particular level of torque output is selected for each of the fired working chambers. Various methods, arrangements and systems related to the above method are also described. | 05-12-2016 |
| 123335000 | By electric means | 2 |
| 20110023822 | Intelli-tach - An electronic means for monitoring and controlling engine performance. The device takes input signals from vehicle engine speed sensor and ignition values. The electronic means is capable of recording an RPM event, and playing it back on the existing vehicle tachometer. Either the entire RPM event may be replayed, or the highest RPM value achieved during the event. Furthermore, the electronic means comprises a dial to set the RPM limit of an engine to prevent over-revving. Once the engine reaches the maximum user-defined RPM value, the electronic means interrupts the ignition system to prevent the engine from revving above such pre-determined value. The electronic means further comprises a shift light which illuminates once an engine reaches a pre-determined RPM value in order to alert the driver to shift gears. | 02-03-2011 |
| 20160040614 | MULTI-LEVEL SKIP FIRE - In one aspect, a method for controlling operation of an internal combustion engine is described. The engine is operated in a skip fire manner such that selected skipped working cycles are skipped and selected active working cycles are fired to deliver a desired engine output. A particular level of torque output is selected for each of the fired working chambers. Various methods, engine controllers, arrangements and systems related to the above method are also described. | 02-11-2016 |
