Marine diesel engines are advantageous in that they can be operated at high torque in the middle and low, suitable for most applications.

Such marine diesel engines, especially large diesel engines, are produced by using the diesel engine of Wartsila of Finland which merged MAN B & W of Germany and Sulzer of Switzerland or by technical cooperation with them.

Conventionally, diesel engines for marine vessels refer to the engine performance curves provided by these engine manufacturers to determine the performance and operating condition of the engine, and operate the vessels based on this.

However, due to the difficulty in calculating the necessary data for the useful use of the curve, the captain of the ship or the shipping company that owns the ship does not fully utilize the engine performance curve.

As a result, there has been a possibility that an engine operation method based on normal experience has been commonly used, so that operating loss due to a decrease in speed, frequent engine damage due to overload operation, or damage to the outer shell of a hull may occur.

For example, experienced and experienced drivers tend to pursue low-load operation for safe operation of the engine, so that they usually operate at a lower speed and thus may cause operational loss, In the case of a skilled driver, there is a possibility that an engine may be damaged due to an overload operation by operating to keep the speed of line.

The captain of the vessel and the shipping company did not find a sharp solution to such extreme driving method and forced the driver to drive safely. there was.

On the other hand, the present applicant filed a "Method for managing the performance of a marine diesel engine" of Korean Patent No. 10-1823074 (Patent Document 2), and using the operation data of the diesel engine installed in the marine vessel, The present invention relates to a method for controlling the performance of a marine diesel engine capable of operating with sufficient engine characteristics by analyzing the state of consumption of the marine vessel and the operation status of the marine vessel to overcome the operating loss due to a decrease in the marine speed in the marine vessel, It is possible to avoid the damage of the engine or the hull, so that it is possible to expect an economical operation of the ship. However, there is a disadvantage that the master must manually calculate and analyze various data and graphs in order to perform the optimum operation.

In the following description of the present invention, it is to be understood that the present invention is not limited to the above-described embodiments, and various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention. It is to be understood that the detailed description of the configuration and the like may be omitted.

First, let's look at the relationship between horsepower, speed, and engine load line.

If the total resistance (hull resistance) of the ship is R, the area of the lower surface of the water is A, the speed is V, the displacement is D, the length of the ship is L, the horsepower is PS and the fuel consumption is Q, in, it meets the a * V ² α R, α D L ^3, a α L ^2, holds the relationship a α D ^2/3.

From this, we can obtain the relationship of R α V ² * D ^2/3, and ^{R * V α V 3 * D} 2/3.

Further, since the relation of PS alpha R * V is satisfied, a relation of PS alpha V ³ * D ^2/3 can be obtained.

Further, since Q? PS, a relation of Q? V ³ * D ^2/3 can be obtained.

Therefore, in a ship equipped with a diesel engine having a fixed pitch propeller, when the displacement D is constant, that is, it can be assumed that the hull resistance R is constant, the horsepower PS is equal to 3 And the fuel consumption amount Q is also proportional to the third power of the speed V, which can be expressed by the following equations (1) and (2).

From equations (1) and (2), since the horsepower PS and the fuel consumption Q are proportional to the third square with respect to the speed V of the ship, The horsepower PS and the fuel consumption Q do not substantially increase in comparison with the speed V but when the vehicle passes the specific speed section, the horsepower PS and the speed V increase according to the fuel consumption Q, It can be seen that the horsepower (PS) and the fuel consumption (Q) may increase rapidly to raise the speed (V) slightly.

Thus, for example, for a bulk ship, it can be seen that the reduction in fuel consumption (Q) versus the reduction in speed (V) can be significantly reduced by only 2 knots at a nominal flight speed of 14 knots.

When the speed V is constant, the horsepower PS and the fuel consumption Q are proportional to the 2/3 power of the displacement D, which can be expressed by the following equations (3) and (4).

From equations (3) and (4), it can be seen that the horsepower PS and the fuel consumption amount Q when the speed V of the ship is constant are proportional to the 2/3 power of the displacement D, It is preferable to avoid an excessive speed V for the operation of the ship, but it is preferable to increase the displacement D of the ship because the displacement D is relatively dull compared to the displacement D of the ship.

Next, by introducing a constant (K ₁ ) as a constant value with respect to Equation ( ₁ ), the following equation (5) can be expressed.

On the other hand, in the case of a nautical voyage with deteriorated marine climate or an increase in the pollution of the outer shell of the ship, the resistance R of the hull becomes large and the engine speed, that is, the speed V, Pe can be expressed by the following equation (6) by introducing another constant (K ₂ ) as the second constant value with respect to the engine load Pe at this time.

When the overload operation is performed, not only the direct damage to the engine may be caused but also the damage to the outline of the ship may be caused. Therefore, it is found that such an overload operation is not preferable from the economical viewpoint.

On the other hand, when the diesel engine is in the overload operation state, it means an average effective pressure Pe in the cylinder, that is, an increase in the thermal load. Therefore, if the overload operation state is maintained, various damages may occur.

Expected damage that may be caused by overload operation may include a sudden rise in exhaust temperature, a turbocharger surge, and / or burnout or cracking of the cylinder cover, exhaust valve burnout or blow-by, Burns or cracks, abnormal wear or breakage of the piston ring, or damage to the combustion gas contacts such as scuffing or cracking of the cylinder liners.

In particular, when the cycle of wearing the ship in the dry dock for the period of the docking period, that is, the repair of the ship, becomes longer and the contamination of the outer shell of the hull continues, the movement of the operating point, that is, So that the diesel engine enters the overload region.

Therefore, the operation management body of the concerned ship (skipper or shipping company) should pay attention to the movement of the operating point in the management of the engine, and in particular, it is necessary to carefully manage the horsepower of the engine.

The ship engine manufacturer described above has specified the allowable range of horsepower for each engine. Operators can observe the permissible range of the horsepower to extend the life of the engine and enable other economic vessels to operate. have.

Regardless of the marine engine manufacturer, the horsepower acceptable range of each engine may be set to, for example, 90% of the Maximum Continuous Rating (MCR).

For example, from Equation (5), assuming the case of setting a driving horsepower (PS) for safe operation at 90% of the maximum horsepower (MCR), and limiting the driving speed to 100% of the maximum speed K ₁ = PS / V ³ , and from this, K ₁ = 100/100 ³ can be calculated, so that K ₁ = 10 ^-4 , and the safe load limit value of the marine engine can be calculated by the following equation (7).

Thus, it can be seen that the ^{V = (90/10 -4)} 1/3 = 96.55%.

On the other hand, from Equation (8), the load (Pe) of the engine can be obtained by using Equation (6).

Therefore, K ₂ = 100 * 100/100, from which K ₂ = 10 ² can be calculated.

As a result, Pe = 10 ² * 90 / 96.55, and it can be understood that the load (Pe) of the engine is 93.22%.

According to the above calculation results, if the driving horsepower (PS) is set to 90% of the maximum horsepower (MCR) for safe driving and the running speed is limited to 100% of the maximum speed, the running load is 93.22% A safety load limit value that can be set to about 93% for convenience) can be obtained.

At this time, restrictions on other operation data (for example, intake / exhaust temperature, maximum cylinder pressure, number of revolutions of the turbocharger, air pressure of the turbocharger, etc.) during the operation in compliance with the safety load limit value are not limited to the above- .

For reference, the exhaust temperature limit value for each engine may be as follows.

Engine type The inlet gas temperature of the turbocharger The outlet gas temperature of the turbocharger WARSILA 515 DEG C - MAN B & W 490 ° C 315 ℃

At this time, the graphs can be manually displayed. However, in the case of using the configuration of an electronic computer system (or computer system) including a server, not only the various data and the related limit values can be displayed simultaneously in real time , The operation management body will be able to immediately carry out the current state of the diesel engine and the future operation.

Then, the horsepower ratio PS (%) and the speed ratio N (%) of the engine are calculated, and then the current operating point is located.

The horsepower of the engine must be carefully managed. Specifically, it should be kept within the safe load operation range or the allowable load operation range during operation of the engine. For example, since the operation of the engine in the overload operation range is very dangerous, Should be avoided.

In particular, in the case of marine diesel engines, it is ideal to operate in the safe load operating region, that is, in the region below the propeller design curve.

Therefore, continuous operation in the permissible load operating area beyond the safe load operating area and passing the propeller design curve means that the debris of the shell is progressing. Therefore, In the event of cleaning or inevitability of living creatures, it is possible to determine the time of arrival of the ship in dry dock at a later stage.

On the other hand, in the case of operation in the allowable load operation region, various operation data (e.g., horsepower (PS), load (Pe), etc.) of the engine is referred to the limit value of each engine manufacturer, , And special precautions should be taken to avoid exceeding the limits.

For reference, it is preferable that the inlet gas temperature and the outlet gas temperature of the turbocharger according to each engine type of the engine manufacturer maintain the following temperature range.

In this way, maintaining the inlet gas temperature and the outlet gas temperature of the turbocharger within a predetermined range is effective in preventing damage to the engine itself and / or damage to the engine itself, particularly when the temperature of the inlet gas and particularly the outlet gas This may cause damage to various parts constituting the engine.

The maximum operating point allowed in each of the operating regions (for example, the safe load operating region or the overload operating region) can be obtained.

Specifically, the estimated speed ratio due to horsepower ratio for the current operating point is the calculation using Equation 5 V = automatically calculated because the value of the (non-horsepower / ^10-4 in the current operating point), ^{one third} estimated speed ratio , The current speed ratio is subtracted from the expected speed ratio. If the value is "+", it is interpreted as operating in the safe load operating region. If the value is "-", it is interpreted as operating in the overload operating region.

For each of the operation regions, a limit line can be set, for example, the speed ratio is 100%, the horsepower ratio is 90%, or the load ratio is 93%.

First, let us examine the safe load operating area.

If the limit line of the speed ratio in the safe load operating region is 100%, then inputting the K ₁ value and the speed limit value in Equation (5), the horsepower PS = current horsepower ratio / current speed ratio ³ * 100 ³ The maximum allowable horsepower ratio can be obtained from the formula.

On the other hand, if the horsepower ratio is limited to 90%, the equation (5) is modified to V = (PS / K ₁ ) ^1/3 and the K ₁ value and the horsepower limit value are input to this equation, Horsepower ratio / current speed ratio ³ ) From the expression of ^1/3 , the value of the maximum allowable speed ratio can be obtained.

The operation load at this time can be limited to, for example, 93%. In this case, when the value of K ₂ = 10 ² and the operation load unlimited value are input in Equation 6 , 93 = 10 ² * PS / V can be obtained.

If we calculate this equation again for V, we can get V = 10 ² * PS / 93.

By substituting the value of this speed ratio and the value of K ₁ into the equation (5), the allowable maximum horsepower ratio can be obtained from the equation of PS = current speed ratio / current speed ratio ³ * (10 ² * PS / 93) ³ .

Substituting the value of the maximum allowable horsepower ratio and the value of K ₂ = 10 ² and the operation load limit value into the equation (6), the value of the maximum allowable speed ratio is obtained from the formula of V = 10 ² * Can be obtained.

3, Case 1 and Case 2 are all indicated as having a positive ("+") value of the operation region, while cases 3 to 5 indicate that the value of the corresponding operation region is negative ("-") value.

For example, for the current operating point of the horsepower ratio 82 and the speed ratio 97, the estimated horsepower ratio becomes 89.8% when the speed ratio is limited to 100%, and the estimated horsepower ratio (PS) It should be noted that in the case of the operation area, it is possible to designate the "safe load operating area", and in this case, the horsepower (PS) can be increased a little more.

Alternatively, for the current operating point of the horsepower ratio 84 and the speed ratio 96, the predicted speed ratio becomes 98.2% when the horsepower ratio is limited to 90%, and the predicted speed ratio N (% Area, it is possible to designate the "permissible load operating area", and in this case, it is necessary to raise the horsepower (PS) further than the "safe load operating area" point.

Further, for example, when the load ratio is limited to 93% with respect to the current operating point, the estimated horsepower ratio and the predicted speed ratio can be determined to be 87.9 and 94.6, respectively.

When the above results are gathered, it is possible to obtain the point of the safe load operating region by finding the maximum permissible operating point which is the intersection point with the limit line while moving along the above-mentioned cubic curve with respect to the present operating point.

At this time, the method of finding the maximum permissible operating point which is an intersection point with the limit line while moving along the third-order curve is also possible by hand, as described above. However, since the real-time property is lowered, In this case, it is expected that a real-time city is possible.

Here, if it is in the safe load operating range, it is possible to drive to the maximum permissible operating point.

However, if it belongs to the overload operation area, it should be operated by descending to the maximum permissible operating point.

In this way, for each operation point, it can be seen that, when the operation management subject belongs to the safe load operation area, it can be raised when the operation point is lower than the allowable maximum operation point. In case of belonging to the overload operation area, So that the engine can be safely operated and the speed of the engine can be increased.

Next, the calculation method of the horsepower including the estimation will be described.

In order to calculate the horsepower, basic data is required. In order to model the ship in actual operation, the ballast water of the ship is filled and the operation data during the voyage is obtained from the sea under 3 wind power with the cargo loaded.

Measurements of fuel consumption (Q), cylinder oil consumption, RPM, cylinder lubricator, and revolving system are performed once every 2 hours in the operation data, and recording of PV diagram can be performed during the above measurement time.

The calculation method of the horsepower (BHP1 to BHP5) may be as follows.

BHP1 is the horsepower calculated from the PV diagram (INDICATOR diagram), BHP2 is the horsepower calculated by the fuel consumption, and BHP2 can be expressed by the following equation (9).

From here,

BHP: Land trial run 90% load horsepower

POS: Land trial run Electricity tank fuel pump average value / indicator of load indicator

N: Land trial run Number of revolutions

POSA: current value of the electric fuel pump indicator of the current engine / indicator of the load indicator

NA: Actual average value of the number of revolutions

GA: Weight of fuel currently in use

HUA: Low calorific value of current fuel

On the other hand, BHP4 is the horsepower calculated by the number of revolutions of the turbocharger and the fuel consumption rate, and can be calculated by the following equation (11).

From here,

WO: The present turbocharger rotational speed is plotted on the performance curve and crossed with the fuel consumption rate curve, and the fuel consumption rate
