Product Guide 1. Main Data and Outputs Main Data and Outputs Maximum continuous output Table 1.1 Rating table for Wärtsilä 34DF Cylinder configuration The mean effective pressure Pe can be calculated using the following formula: where: Pe = mean effective pressure [bar] P = output per cylinder [kW] n = engine speed [r/min] D = cylinder diameter [mm] L = length of piston stroke [mm] c = operating cycle (4) Product Guide Wärtsilä 34DF - 3/2012

Product Guide 1. Main Data and Outputs Derating of output in gas mode 1.3.1 Derating due to methane number and charge air receiver temperature Figure 1.1 Derating due to methane number and charge air receiver temperature Compensating a low methane number gas by lowering the charge air receiver temperature below 45 °C is not allowed. Minimum charge air receiver temperature is 35°C. Compensating a higher charge air receiver temperature than 55 °C by a high methane number gas is not allowed. The dew point shall be calculated for the specific site conditions. The minimum charge air receiver temperature...

Figure 1.2 Derating of output for gas feed pressure and LHV Derating factor (KQAS' NOTE! The above given values for gas feed pressure is before the engine (after the gas regulating unit). No compensation (uprating) of the engine output is allowed, neither for gas feed pressure higher than required in the graph above nor lower heating value above 36 MJ/m3N . If the gas pressure is lower than required, a pressure booster unit can be installed before the gas regulating unit to ensure adequate gas pressure. If pressure arise is not possible the engine output has to be adjusted according to above. A...

Product Guide 1. Main Data and Outputs Reference conditions The output is available within a range of ambient conditions and coolant temperatures specified in the chapter Technical Data. The required fuel quality for maximum output is specified in the section Fuel characteristics. For ambient conditions or fuel qualities outside the specification, the output may have to be reduced. The specific fuel consumption is stated in the chapter Technical Data. The statement applies to engines operating in ambient conditions according to ISO 3046-1:2002 (E). total barometric pressure relative humidity charge...

Product Guide 2. Operating Ranges Operating Ranges Engine operating range Below nominal speed the load must be limited according to the diagrams in this chapter in order to maintain engine operating parameters within acceptable limits. Operation in the shaded area is permitted only temporarily during transients. Minimum speed is indicated in the diagram, but project specific limitations may apply. 2.1.1 Controllable pitch propellers An automatic load control system is required to protect the engine from overload. The load control reduces the propeller pitch automatically, when a pre-programmed...

Product Guide 2. Operating Ranges Remarks: The maximum output may have to be reduced depending on gas properties and gas pressure, refer to section "Derating of output in gas mode". The permissible output will in such case be reduced with same percentage at all revolution speeds. Restrictions for low load operation to be observed. Loading capacity Controlled load increase is essential for highly supercharged engines, because the turbocharger needs time to accelerate before it can deliver the required amount of air. Sufficient time to achieve even temperature distribution in engine components must...

Product Guide 2. Operating Ranges 2.2.1 Mechanical propulsion, controllable pitch propeller (CPP) Figure 2.2 Maximum load increase rates for variable speed engines The propulsion control must not permit faster load reduction than 20 s from 100% to 0% without automatic transfer to diesel first. 2.2.2 Electric propulsion Figure 2.3 Increasing load successively from 0 to 100% MCR The propulsion control and the power management system must not permit faster load reduction than 20 s from 100% to 0% without automatic transfer to diesel first.

In electric propulsion applications loading ramps are implemented both in the propulsion control and in the power management system, or in the engine speed control in case isochronous load sharing is applied. When the load sharing is based on speed droop, it must be taken into account that the load increase rate of a recently connected generator is the sum of the load transfer performed by the power management system and the load increase performed by the propulsion control. The electrical system must be designed so that tripping of breakers can be safely handled. This requires that the engines...
