Power ratings from 410 to 500 HP
The Cursor 13 is a 12,880 cc, in-line six-cylinder engine available with three power ratings:
o 410HP with fixed-geometry turbo and waste-gateo 450 and 500HP with variable-geometry turbo (VGT).
The Cursor 13 500HP engine delivers peak torque of 2,300Nm from 1,000 rpm and keeps it constant up to 1,525 rpm.
The Cursor 13 410HP engine is equipped with Iveco's Combined Engine Brake.
CEB: Double-acting engine brake
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 reliabilityThe 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.
