The normal startup of the Ricardo 20kW diesel generator set is affected by four key factors:   Battery type and charge level: The type and charge level of the battery directly affect the startup success rate.   Ambient temperature: Ambient temperature impacts the battery's discharge rate and the starting resistance torque of the diesel engine.   Starting resistance torque: It includes internal friction resistance torque, initial compression resistance torque, and the inertial torque required to accelerate the engine from a static state to the starting speed.   Starter motor power: The rated power of the starter motor is used to overcome the starting resistance torque, with energy entirely derived from the battery.
