Cursor engines

The Stralis tractors and wagons are equipped with Cursor 10 engines in two power levels :

- 400 HP ( 294 kW ) and 430 hp ( 316 kW ) and the Cursor 13 engine with 480 hp ( 353 kW ) and 540 hp ( 397 kW ) . Both engines are equipped with direct injection high pressure . The single pump-injectors are actuated by a camshaft in the head. The supercharger is guaranteed by the variable geometry turbocharger , optimized in order to achieve the best performance at all engine speeds . The action of the decompression engine brake is powered by the turbocharger . All the engine functions are controlled by electronics : injection advance, geometry turbo , engine brake and cruise control . The control unit is connected to other electronic units that control the gearbox , brakes and transmission braking . The two are obviously Cursor engines comply with Euro 3 of the Directive on emissions.

Of all calibrations engine is available for approval 4 ecopoints
Cursor engines are characterized by a wide range of torque (400 rev / min) , which was followed by a field of constant maximum power of 500 rev / min on the Cursor 10 and almost 400 rev / min on the Cursor 13. The new Cursor 13-540 so delivers the maximum power already at 1600 rev / min.

The new 540 HP Cursor 13
The Cursor 13 possesses the structural characteristics common to other Cursor . The rigidity of the engine block is ensured by a " sub-block " that integrates the seven bearing caps on which rests the crankshaft , and a cylinder head block. The distribution is on the side of the flywheel to transmit, without vibration and with little noise , the driving forces of the 24 valves and 6 injectors . The pistons aluminum monobloc favor the dispersion of the combustion heat to the wet shirts suspended , avoiding peaks of temperature harmful to the oil circulating in the piston head .
The latest addition , the Cursor 13 engine with 540 HP, runs for a long time on customers' vehicles . With the experience accumulated in four years of trials and working with customers from the other two engines of this range , the Cursor 13 engine has an estimated life span unbeatable.

Iveco Turbo Brake : a retarding power of 408 hp continuously
All Cursor engines are equipped as standard with a decompression brake " supercharged " : the partial reopening of the exhaust valves at the end of the compression phase will increase the " engine braking " , taking advantage of the resistant strain . With the help of variable geometry turbocharger , which fills with air cylinders, the braking power of the ITB (Iveco Turbo Brake ) reaches 280 kW (380 hp ) at 2600 rev / min in a continuous way on the Cursor 10 and 300 kW ( 408 hp ) at 2400 rev / min in continuous mode or 240 kW (326 hp) at 1900 r / min on the Cursor 13. The performance of the ITB are comparable to those of a transmission brake . Finally, the decompression brake , modulated by action on the geometry of the turbo , you can adjust the speed downhill. The technique of decompression brake is superior to that of the brakes on the drain, as it does not cause overheating of the upper parts of the engine. Another advantage , the heat produced by the absorption of energy by the ITB is largely dissipated with the exhaust gases and does not go to overload the cooling system of the engine , which remains available for the transmission brake .
