The Volvo Penta Stage V D16 off-road engine provides ROPA sugar beet harvesters with great power and reliability.
Michael Gruber, Sugar Beet Technical Director at ROPA in an interview with Volvo Penta.
This engine was designed by Volvo Penta especially for use in the Tiger 6S. With a capacity of 16.12 liters, common rail injection, SCR catalytic converter, and AdBlue, this type of engine provides power more efficiently and "cleanly."
With doubled turbocharging, this power package generates enormous maximum torque of 3,650 Nm. Starting at 1,000 rpm, it provides 3,550 Nm, which means that you can harvest longer in the lower speed range and therefore save more fuel. Thanks to the modern engine technology, this diesel engine also complies with the European exhaust stage V without exhaust gas recirculation.
The basis for greater daily output with less fuel consumption and even more power at lower speeds.
As a unique selling proposition on the market of 3-axle sugar beet harvesters, the Tiger has a direct power transmission via directly linear situated cardan shafts from traction drive to both rear axles and front axle, which is a great advantage for better traction in changing or difficult soil and harvesting conditions. The hydraulic chassis always distributes the load evenly.
The new stepless traction drive was specifically developed by ROPA, Omsi and Bosch Rexroth for the ROPA Tiger with its high drive power. The "constant variable ROPA" transmission (CVR) consists of three hydraulic motors on a compound gearbox and is located between the engine compartment and the third axle. The maximum speed of 40 km/h can be reached by the Tiger 6S at economical 1200 rpm. Harvesting in the field requires an engine speed of only 1,100 rpm. Depending on power requirements the rotational speed of the Tiger is automatically regulated up to 1,650 rpm. The multi-disk differential brakes integrated into the axles (protected from dirt) running in an oil bath "tame" the Tiger as required.
