The transient event may be detected based on, for example, the change in input power or engine speed caused by the event. The transient event fuel substitution ratio may be specified, or may be calculated based on a knock limit air fuel ratio or other factors. | 12-18-2014 |

| 20080264381 | Fuel Injection System - There is well known that the much timing of fuel injection is advanced, the much start ability of an engine is improved. However, with regard to the conventional fuel injection system, when stopping process of the engine is performed, a timer piston determining timing of fuel injection remains at a position at which the piston exists at the time that the stopping process is performed. Then, at the time of next starting of the engine, the timer piston does not often exist in the advanced angle side and the start ability may be bad. | 10-30-2008 |

| 20140096744 | INTERNAL COMBUSTION ENGINE CONTROL METHODS - A control apparatus controls an actual output engine RPM close to a target RPM that is based on an operational amount of an operating member independent of engine load fluctuations. The control apparatus temporarily increases the target RPM relative to a basic target RPM previously determined according to the operational amount. An acceleration control gradually increases the target RPM equal to or greater than a predetermined increase rate. When the temporary increase and acceleration controls are performed simultaneously, and the temporary increase control is later canceled, an increase rate of the target RPM is set equal to or greater than an increase rate of a basic target RPM corresponding to the operational amount so the target RPM does not become lower than a present RPM. The target RPM and the basic target RPM are thereby gradually matched with each other. | 04-10-2014 |
