Agroplus F Ecoline tractors are equipped with three

and four cylinder SDF Series 1000 TIER III engines with simple turbo or turbo-intercooler forced induction and an electronic governor system.
Incredibly tough and reliable, these engines are specifically built to keep on working uninterruptedly for hours on end with low running costs and extremely limited maintenance for minimised loss of productivity.
The modern high pressure injection system uses a single pump for each cylinder. This is a far more advanced solution than the rotary or in-line pumps used in conventional injection systems, and ensures superlative performance with extraordinary reliability.
Euro III A engines are equipped with HRT (Hydraulic Roller Tappets) technology, a system controlled by an electrohydraulic valve to optimise the injection of fuel into the combustion chamber. During engine starts while the engine oil is still cold, the system increases valve lift slightly to advance the injection timing, optimising engine efficiency right from the start of the day and in any weather conditions, and eliminating the unpleasant white exhaust smoke typically produced by engines under cold starting conditions.
The fuel injection system is controlled electronically by the engine management ECU, which continuously monitors engine load and optimised engine function accordingly.
The driver can also set and store engine speeds for specific operations. Whenever an application calls for a constant engine speed, the governor automatically maintains the preset engine speed value. This increases productivity and also makes headland turns quicker and easier.
Agroplus F Ecoline also features internal EGR exhaust gas recirculation (with recirculation taking place directly in the combustion chamber).
During the intake cycle, a dedicated cam lobe keeps the exhaust valve partially open. This mixes a small proportion of exhaust gas and returns it to the cylinder, where a second combustion process eliminates any unburnt hydrocarbon particulate, keeping exhaust emissions as low as possible.
