A work apparatus has an internal combustion engine and a starter device for starting the engine. Within a housing of the work apparatus, a first electrical component is arranged at a first location and a second electrical component is arranged at a second location. A control unit is provided which is connected to the first electrical component and to the second electrical component. The control unit detects a first temperature-dependent value of the first electrical component at the first location, and a second temperature-dependent value of the second electrical component at the second location, and identifies the starting conditions as a function of these values. The first electrical component is a first actuator and the second electrical component is a second actuator or a sensor.

A method for managing temperature of a piston of an engine of a vehicle, the method comprises determining, by a throttle position sensor connected to a controller, a throttle position of a throttle valve of the engine, determining, by an engine speed sensor connected to the controller, an engine speed (RPM) of the engine, and determining, by the controller, an estimated piston temperature based on at least the throttle position and the engine speed.

A thermal management system for controlling cooling of an engine system during shutdown, the engine system includes an engine configured to provide power to a working machine, wherein the thermal management system includes a controller which is configured to receive a signal indicative of an engine shutdown command. The controller is further configured to derive, infer or receive a temperature parameter of the engine system and to determine whether the temperature parameter of the engine system is above a first predetermined threshold; and wherein the controller is configured to signal the progressive reduction of a speed of the engine prior to issuing a signal to shutdown the engine in the event that the first predetermined threshold is exceeded when the engine shutdown command is received, thereby cooling the engine system prior to engine shutdown.
