Technical Field

The invention belongs to the technical field of engine oil consumption measurement, and particularly relates to a device and a method for measuring engine oil consumption of a diesel engine.

Background

The measurement of the oil consumption of the engine mainly comprises a direct method and an indirect method at present. The direct method determines oil consumption by measuring changes in the amount of oil in the engine sump. The indirect method is mainly used for calculating the oil consumption of the engine by detecting the content of a tracer element in the exhaust gas of the engine. The former is realized more simply and quickly with less investment, and the latter needs special detection equipment.

However, it takes time to measure the engine oil by the direct method, and an observation error occurs when the oil level of the oil pan is observed artificially, thereby affecting the accuracy of measuring the engine oil consumption.

Disclosure of Invention

In order to solve the problems in the prior art, the invention aims to provide a device and a method for measuring the oil consumption of a diesel engine, which are accurate and convenient to measure.

The technical scheme adopted by the invention is as follows:

the utility model provides a diesel engine oil consumes measuring device, includes the oil pan, is provided with first oil cup by the oil pan, through the pipeline intercommunication between the lower extreme of first oil cup and the oil pan, is provided with the oil spilling mouth on the first oil cup, and the oil spilling mouth department of first oil cup has the second oil cup that is used for connecing the oil spilling through the pipeline intercommunication.

When the first oil cup is filled with oil, the oil flows to the oil pan, so that the oil is filled into the oil pan. When the oil is spilled from the oil spilling port of the first oil cup, the engine oil does not flow to the oil pan any more. At this time, the engine oil in the first oil cup overflows to the second oil cup. The oil overflowing amount in the second oil cup is subtracted from the oil filling amount, and the oil filling amount in the oil pan can be calculated. And the computer oil consumption rate can be calculated, which is (filling weight-overflowing weight)/(operating power operating time).

The oil level is calibrated through the oil overflow port, so that the problem that errors occur when the oil level is observed manually is solved, and the accuracy of calculating the actual oil consumption and the oil consumption rate is improved.

In a preferred embodiment of the present invention, a first valve is connected to a pipe between the first oil cup and the oil pan. The first valve may be closed when oil does not need to be filled to the oil pan through the first oil cup.

As a preferable scheme of the present invention, a second valve is connected to a pipe between the first oil cup and the second oil cup. The second valve may be closed when it is not necessary to spill the oil in the first cup into the second cup.

A diesel engine oil consumption measuring method comprises the following steps:

s1: adjusting the height of the first oil cup; when the oil spilling port of the first oil cup begins to spill oil, calibrating the oil level on the oil pan;

s2: filling oil into the first oil cup, wherein the oil in the first oil cup flows into an oil pan until the first oil cup overflows;

s3: calculating the weight of the filled engine oil; weighing the weight of the overflowed engine oil;

s4: and subtracting the weight of the overflowed engine oil from the weight of the injected engine oil to obtain the actual engine oil consumption.

As a preferable scheme of the invention, the method further comprises the following steps:

s5: recording the running time and power in the time period between two times of filling the engine oil;

s6: computer oil consumption rate; wherein, the computer oil consumption rate is (filling weight-overflowing weight)/(operating power operating time).

And the oil spilling port of the first oil cup is enabled to begin to spill oil by adjusting the height of the first oil cup so as to calibrate the oil level of the oil pan. Therefore, when engine oil is filled to the oil spilling at each time, the oil levels in the oil pan are all consistent, and the problem of error in manual oil level observation is solved. In the time period of two times of filling mechanisms, the method can accurately calculate the actual oil consumption, namely subtracting the weight of the overflowed oil from the weight of the filled oil to obtain the actual oil consumption. And, the computer oil consumption rate is (fill weight-spill weight)/(operating power operating time). Because the oil level is accurately calibrated through the oil overflow port, the actual engine oil consumption and the engine oil consumption rate are more accurately calculated.

As a preferable aspect of the present invention, in step S3, when the weight of the engine oil to be filled is calculated, the weight of the engine oil to be filled is obtained by recording the amount of oil before the filling and the amount of oil after the filling by the filling device, and subtracting the amount of oil after the filling from the amount of oil before the filling. The oil filling amount can be directly read by oil filling equipment, or obtained by subtracting the oil amount after filling from the oil amount before filling.

The invention has the beneficial effects that:

after the height of the first oil cup is adjusted, the oil spilling port of the first oil cup begins to spill oil so as to calibrate the oil level of the oil pan. Therefore, when engine oil is filled to the oil spilling at each time, the oil levels in the oil pan are all consistent, and the problem of error in manual oil level observation is solved. In the time period of two times of filling mechanisms, the method can accurately calculate the actual oil consumption, namely subtracting the weight of the overflowed oil from the weight of the filled oil to obtain the actual oil consumption. And, the computer oil consumption rate is (fill weight-spill weight)/(operating power operating time). Because the oil level is accurately calibrated through the oil overflow port, the actual engine oil consumption and the engine oil consumption rate are more accurately calculated.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

As shown in fig. 1, the diesel engine oil consumption measuring device of the embodiment includes an oil pan 1, a first oil cup 2 is disposed beside the oil pan 1, the lower end of the first oil cup 2 is communicated with the oil pan 1 through a pipeline, an oil overflow port is disposed on the first oil cup 2, and a second oil cup 3 for containing oil overflow is communicated with the oil overflow port of the first oil cup 2 through a pipeline.

When the first oil cup 2 is filled with oil, the oil flows toward the oil pan 1, thereby achieving oil filling of the oil pan 1. When the oil is spilled to the oil spill port of the first oil cup 2, the engine oil no longer flows to the oil pan 1. At this time, the engine oil in the first oil cup 2 overflows to the second oil cup 3. The amount of oil that is filled into the oil pan 1 can be calculated by subtracting the amount of oil spilling in the second oil cup 3 from the amount of oil that is filled. And the computer oil consumption rate can be calculated, which is (filling weight-overflowing weight)/(operating power operating time).

The oil level is calibrated through the oil overflow port, so that the problem that errors occur when the oil level is observed manually is solved, and the accuracy of calculating the actual oil consumption and the oil consumption rate is improved.

Furthermore, a first valve 4 is connected to a pipeline between the first oil cup 2 and the oil pan 1. When it is not necessary to fill the oil pan 1 with oil through the first oil cup 2, the first valve 4 may be closed. And a second valve 5 is connected on a pipeline between the first oil cup 2 and the second oil cup 3. When it is not necessary to overflow the oil in the first oil cup 2 to the second oil cup 3, the second valve 5 may be closed.

The method for measuring the oil consumption of the diesel engine comprises the following steps of:

s1: adjusting the height of the first oil cup 2; when the oil spilling port of the first oil cup 2 begins to spill oil, calibrating the oil level on the oil pan 1;

s2: filling oil into the first oil cup 2, wherein the oil in the first oil cup 2 flows into the oil bottom shell 1 until the first oil cup 2 overflows;

s3: calculating the weight of the filled engine oil; weighing the weight of the overflowed engine oil;

s4: and subtracting the weight of the overflowed engine oil from the weight of the injected engine oil to obtain the actual engine oil consumption.

As a preferable scheme of the invention, the method further comprises the following steps:

s5: recording the running time and power in the time period between two times of filling the engine oil;

s6: computer oil consumption rate; wherein, the computer oil consumption rate is (filling weight-overflowing weight)/(operating power operating time).

The height of the first oil cup 2 is adjusted to enable the oil spilling port to begin to spill oil so as to calibrate the oil level of the oil pan 1. Therefore, when engine oil is filled to the oil spilling at each time, the oil levels in the oil pan 1 are all consistent, and the problem of error in manual oil level observation is solved. In the time period of two times of filling mechanisms, the method can accurately calculate the actual oil consumption, namely subtracting the weight of the overflowed oil from the weight of the filled oil to obtain the actual oil consumption. And, the computer oil consumption rate is (fill weight-spill weight)/(operating power operating time). Because the oil level is accurately calibrated through the oil overflow port, the actual engine oil consumption and the engine oil consumption rate are more accurately calculated.

Further, in step S3, when the weight of the engine oil to be filled is calculated, the weight of the engine oil to be filled is obtained by recording the amount of oil before the filling device is filled and the amount of oil after the filling device is filled, and subtracting the amount of oil after the filling device from the amount of oil before the filling device is filled. The oil filling amount can be directly read by oil filling equipment, or obtained by subtracting the oil amount after filling from the oil amount before filling.

The invention is not limited to the above alternative embodiments, and any other various forms of products can be obtained by anyone in the light of the present invention, but any changes in shape or structure thereof, which fall within the scope of the present invention as defined in the claims, fall within the scope of the present invention.
