Wärtsilä 46F Product Guide1. Main Data and Outputs

2. Operating Ranges

2.1 Engine operating range

Running 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 load versus speed
curve (“engine limit curve”) is exceeded, overriding the combinator curve if necessary. The
engine load is derived from fuel rack position and actual engine speed (not speed demand).

The propulsion control must also include automatic limitation of the load increase rate.
Maximum loading rates can be found later in this chapter.

The propeller efficiency is highest at design pitch. It is common practice to dimension the
propeller so that the specified ship speed is attained with design pitch, nominal engine speed
and 85% output in the specified loading condition. The power demand from a possible shaft
generator or PTO must be taken into account. The 15% margin is a provision for weather
conditions and fouling of hull and propeller. An additional engine margin can be applied for
most economical operation of the engine, or to have reserve power.

Wärtsilä 46F Product Guide - a19 - 1 December 2017 2-1

2. Operating RangesWärtsilä 46F Product Guide

2.2 Loading capacity

Controlled load increase is essential for highly supercharged diesel 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 also be ensured.
This is especially important for larger engines.

If the control system has only one load increase ramp, then the ramp for a preheated engine
should be used. The HT-water temperature in a preheated engine must be at least 60 ºC,
preferably 70 ºC, and the lubricating oil temperature must be at least 40 ºC.

The ramp for normal loading applies to engines that have reached normal operating
temperature.

Emergency loading may only be possible by activating an emergency function, which generates
visual and audible alarms in the control room and on the bridge.

The load should always be applied gradually in normal operation. Class rules regarding load
acceptance capability of diesel generators should not be interpreted as guidelines on how to
apply load in normal operation. The class rules define what the engine must be capable of, if
an unexpected event causes a sudden load step.

2.2.1 Mechanical propulsion, controllable pitch propeller (CPP)

Fig 2-2 Maximum load increase rates for variable speed engines

If minimum smoke during load increase is a major priority, slower loading rate than in the
diagram can be necessary below 50% load.

In normal operation the load should not be reduced from 100% to 0% in less than 15 seconds.
When absolutely necessary, the load can be reduced as fast as the pitch setting system can
react (overspeed due to windmilling must be considered for high speed ships).

2-2 Wärtsilä 46F Product Guide - a19 - 1 December 2017

Wärtsilä 46F Product Guide2. Operating Ranges

2.2.2 Diesel electric propulsion

Fig 2-3 Maximum load increase rates for engines operating at nominal speed

In normal operation the load should not be reduced from 100% to 0% in less than 15 seconds.
In an emergency situation the full load can be thrown off instantly.

The maximum deviation from steady state speed is less than 10%, when applying load
according to the emergency loading ramp. Load increase according to the normal ramp
correspondingly results in less than 3% speed deviation.

2.2.2.1 Maximum instant load steps

The electrical system must be designed so that tripping of breakers can be safely handled.
This requires that the engines are protected from load steps exceeding their maximum load
acceptance capability. The maximum permissible load step for an engine that has attained
normal operating temperature is 33% MCR. The resulting speed drop is less than 10% and
the recovery time to within 1% of the steady state speed at the new load level is max. 5
seconds.

When electrical power is restored after a black-out, consumers are reconnected in groups,
which may cause significant load steps. The engine must be allowed to recover for at least
10 seconds before applying the following load step, if the load is applied in maximum steps.

2.2.2.2 Start-up time

A diesel generator typically reaches nominal speed in about 25 seconds after the start signal.
The acceleration is limited by the speed control to minimise smoke during start-up.

2.3 Operation at low load and idling

The engine can be started, stopped and operated on heavy fuel under all operating conditions.
Continuous operation on heavy fuel is preferred rather than changing over to diesel fuel at low
load operation and manoeuvring. The following recommendations apply:

Absolute idling (declutched main engine, disconnected generator)

● Maximum 10 minutes if the engine is to be stopped after the idling. 3 minutes idling before

stop is recommended.

Wärtsilä 46F Product Guide - a19 - 1 December 2017 2-3

2. Operating RangesWärtsilä 46F Product Guide

● Maximum 6 hours if the engine is to be loaded after the idling.

Operation below 20 % load

● Maximum 100 hours continuous operation. At intervals of 100 operating hours the engine

must be loaded to minimum 70 % of the rated output.

Operation above 20 % load

● No restrictions.

2.4 Low air temperature

In cold conditions the following minimum inlet air temperatures apply:

● Starting + 5ºC

● Idling - 5ºC

● High load - 10ºC

The two-stage charge air cooler is useful for heating of the charge air during prolonged low
load operation in cold conditions. Sustained operation between 0 and 40% load can however
require special provisions in cold conditions to prevent too low HT-water temperature. If
necessary, the preheating arrangement can be designed to heat the running engine (capacity
to be checked).

For further guidelines, see chapter Combustion air system design.

At ISO 15550 conditions (ambient air temperature 25°C, LT-water 25°C). Flow tolerance 5% and temperature tolerance
15°C.

Note

2

At ISO 15550 conditions (ambient air temperature 25°C, LT-water 25°C) and 100% load. Tolerance for cooling water heat
10%, tolerance for radiation heat 30%. Fouling factors and a margin to be taken into account when dimensioning heat ex­changers.

Note

3

According to ISO 15550, lower calorific value 42700 kJ/kg, with engine driven pumps (two cooling water + one lubricating
oil pumps). Tolerance 5%. The fuel consumption at 85 % load is guaranteed and the values at other loads are given for in­dication only.

Note
