摘要: A power unit includes two or more power modules (1, 2, 3), each comprising an engine (11), a transfer case (12) connected to the engine (11) and a hydraulic pump set (13) connected to the transfer case (12). A controlling method for the power unit is also disclosed. Compared to the prior art of using a single super high power engine, the hydraulic mobile crane using the power unit has advantages of low cost, high reliability, and not being subjected to the restrictions by road transportation conditions during transportation.

摘要: Method for controlling the functioning of two heat engines connected to a torque distributor (5) in a fire-fighting vehicle, each engine being provided with automatic transmission and with a first clutch (K1) connecting the first (A) of said engines to a delivery pump of a liquid; with a second clutch (K2) connecting the first engine (A) to the vehicle's traction; with a third clutch (K3) connecting the second engine (B) to the vehicle's traction. The control has an activation or a deactivation step of said delivery pump, by closing or opening said first clutch (K1) at a vehicle speed lower than a threshold higher than zero, and in a condition of decelerating vehicle, with the simultaneous opening or closing of said second clutch (K2), and if said conditions are verified within an interval of time from an activation or deactivation request.
