摘要： Exemplary embodiments are disclosed of controllers (e.g., control panels, etc.) configured to be operable for detecting cavitation using torque load and/or instantaneous fuel consumption. In exemplary embodiments, a controller is configured to be operable for monitoring at least one of engine torque load and/or engine instantaneous fuel consumption for fluctuation (e.g., significant drop/downward fluctuation in average magnitude and/or erratic, noisy, fluctuating data, etc.) indicative of pump cavitation, thereby enabling the controller to be operable for alerting to indications of pump cavitation when fluctuation of the monitored engine torque load and/or engine instantaneous fuel consumption indicate pump cavitation.

摘要： A method for controlling an internal combustion engine system (1) so as to avoid turbo surge and/or shorten power cut off during gearshift, wherein the internal combustion engine system (1) comprises: an internal combustion engine (2) and a gearbox (3) operatively connected to the internal combustion engine (2); a turbocharging arrangement (4) configured to provide a boost pressure of air fed to the internal combustion engine (2); and a control system (5) configured to control operation of the internal combustion engine system (1), the method comprising: providing information about i) a point of time for initiating an upcoming gearshift (ti), ii) a target engine speed after the upcoming gearshift, iii) a target engine torque after the upcoming gearshift, and iv) current operation conditions of the internal combustion engine system (1); determining, based on said information and before the upcoming gearshift is initiated, whether there is a risk of having turbo surge during the upcoming gearshift; and, if such a risk is determined, lowering the boost pressure before initiating the upcoming gearshift.

摘要： A two-stroke combustion engine (100) for use with a tool associated with an inertia, the combustion engine (100) comprising a user-operated throttle control (170), an adjustable valve (150) arranged to control one or more air intakes (140) of the combustion engine, and a control unit (160) arranged to control a state of the adjustable valve (150),
wherein the user-operated throttle control (170) is arranged to control a throttle valve (210) of the combustion engine (100) that is arranged separate from the adjustable valve (150).-
