The CEB – Combined Engine Brake is an uprated engine brake which combines two effects: decompression and braking torque. By means of a butterfly valve on the exhaust manifold, it generates sufficient exhaust gas counterpressure to slow the rotation of the engine and increase the braking force. Waste-gate: more torque, lower fuel consumption, high reliability The design of the waste-gate turbo allows high boost at low engine speeds, thereby optimising torque and fuel consumption. Once maximum turbo pressure (corresponding to high engine speeds) is reached, however, the engine and turbo must be mechanically protected. This task is performed by the waste-gate system, which limits the pressure on the turbo and keeps it constant, by allowing the gradual egress of gases directly to the exhaust manifold in certain conditions. Variable-geometry turbo: more power, no turbo lag The turbo system makes a major contribution to the performance of the engines, and offers strong acceleration, fluid power delivery and high power. It also enhances driving comfort by eliminating turbo lag, because the engine always responds immediately to inputs from the accelerator. By means of an electronic control system, the variable-geometry turbo adapts the geometry of the turbo to the engine speed: thanks to a system of coaxial rotor movement, the turbo adapts to the incoming volume of exhaust gas, thereby optimising control of turbo pressure. ECAS: Electronically Controlled Air Suspension ECAS stands for Electronically Controlled Air Suspension. It is a system which ensures the utmost driver comfort and constant chassis geometry regardless of speed, load and road type. It also acts on the braking pressure, which is delivered in proportion to the load on the axles.

Motor Cursor 13 je 6-cilindrični redni motor radnog obujma 12.880 cm3 dostupan u tri razreda snage: o 410 KS s turbopunjačem nepromjenljive geometrije i rasteretnim ventilom o 450 i 500 KS s turbopunjačem promjenljive geometrije (VGT). Motor Cursor 13 od 500 KS daje najveći okretni moment od 2.300 Nm od 1.000 okr/min i održava ga nepromjenljivim do 1.525 okr/min. Motor Cursor 13 od 410 KS opremljen je Ivecovom kombiniranom motornom kočnicom. CEB: Motorna kočnica s dvostrukim djelovanjem CEB (Combined Engine Brake – kombinirana motorna kočnica) je usavršena motorna kočnica koja objedinjuje dva učinka: dekompresijski i moment kočenja. Putem leptirastog ventila u ispušnoj grani stvara dovoljno protutlaka ispušnih plinova da uspori vrtnju motora i poveća silu kočenja. Rasteretni ventil: veći moment, manja potrošnja goriva, veća pouzdanost Konstrukcija turbopunjača s rasteretnim ventilom omogućuje veliko povećanje snage pri niskim brzinama vrtnje motora čime se postižu optimalni okretni moment i potrošnja goriva. Međutim, nakon postizanja maksimalnog tlaka prednabijanja (sukladno brzini vrtnje motora), motor i turbinu je potrebno mehanički zaštititi. Ovaj zadatak obavlja sustav rasteretnog ventila koji ograničava tlak turbopunjača i održava ga stalnim, omogućujući direktan izlaz plinova izravno u ispušnu granu u određenim uvjetima. Turbopunjač promjenljive geometrije: više snage, bez turbo rupe Sustav turbopunjača je glavni čimbenik u performansama motora te nudi snažna ubrzanja, glatki porast snage i veću snagu. On, isto tako, povećava komfor eliminacijom turbo rupe jer motor uvijek ima trenutačan odziv na pritisak papučice gasa. Putem elektroničkog upravljačkog sustava turbopunjač prilagođava geometriju turbine brzini vrtnje motora: zahvaljujući sustavu koaksijalnog zakretanja rotora, turbopunjač se prilagođava nadolazećem volumenu ispušnih plinova čime se postiže optimalno upravljanje tlakom prednabijanja.
