Embodiments describe a method of controlling a two-stroke internal combustion engine is shown. The method includes selecting one set of two or more sets of engine parameter inputs or a weighted value of two or more sets of engine parameter inputs, determin...

An engine ECU executes a program including the steps of: detecting an engine speed NE and an engine load (S100, S 110); when determination is made of being in an idle region based on the engine speed NE and engine load (YES at S120), determining whether in...

When an engine speed is in a low speed region, a fuel injection amount is calculated at a first calculation timing (at an angle interrupt process of the crank angle) which is immediately after detection of a peak engine speed (S220). Accordingly, the peek ...

The method involves adapting different types of fuel-air mixture deviation by estimating the influence of a first type of mixture deviation on a previously conducted mixture deviation of a second type during or after adaptation of the first type of mixture...

To prevent the sticking of the valve body of an electromagnetic valve under idling conditions or under non-injection conditions in a control device of common rail fuel injection system of an engine wherein the fuel supplied from a feed pump (6) is pressuri...

The amount of a change in the fuel injection amount that needs be made in accordance with a change in the target idle speed NETRG is corrected by the rotation speed correction factor QIPNT. When the engine friction is changed due to a change in the actual ...

Based on rotational speed information on a rotational speed of an internal combustion engine, it is discriminated whether or not the rotation speed of the internal combustion engine increases to be out of control to generate a control signal and the rotati...
