STEYR diesel technology – where innovation is tradition

STEYR Profi tractors bring you a powerful range of 4 and 6 cylinder engines to meet your specific farming requirements at the same time as complying with environmental legislation for over the next decade. Profi engines feature an enhanced power to weight ratio and extra torque in abundance. Take on the heaviest tillage jobs or the most critical of haymaking schedules. Profis continue to deliver extremely high torque at low revs, but "tread lightly" when you need to protect the sward for rapid re growth.

STEYR common rail technology for efficiency and response
All Profi 4-valve engines feature high-pressure common rail technology. Whereas standard diesel injection systems need to build up pressure for each cycle, this system maintains a constant pressure of up to 1400 bar in a fuel rail connected directly to the injection nozzles. The torque needed to drive the pump is only 10% of that needed for a standard distributor pump. The engine control unit (ECU) governing the timing and fuel flow rate is connected to the on-board CAN bus system. In addition to saving fuel consumption, there is also an exciting gain in responsiveness to be experienced.
