Description

Technical Field

[0001] This utility model belongs to the field of diesel engine technology, specifically a single-sided fuel supply device for a diesel engine in an internal combustion locomotive. Background Technology

[0002] A diesel engine is an internal combustion engine that uses diesel fuel. It works by converting the chemical energy of diesel fuel into mechanical energy. It operates based on the principle of compression ignition. During the intake stroke, air is drawn into the cylinder. During the compression stroke, the piston compresses the air, causing the air temperature and pressure to rise sharply. Then, diesel fuel is injected into the cylinder through the injector. The diesel fuel mixes with the high-temperature and high-pressure air and ignites spontaneously, pushing the piston downward to complete the power stroke. Finally, during the exhaust stroke, the piston expels the combusted exhaust gas from the cylinder. This cycle repeats continuously, converting the chemical energy of diesel fuel into mechanical energy for output.

[0003] When the locomotive is idling, the diesel engine continuously supplies fuel to both cylinders, resulting in unnecessary fuel waste. For example, during maintenance operations or crew meal times, the diesel engine maintains a low speed, and the dual-cylinder fuel supply at this time leads to high fuel consumption, increasing operating costs. Moreover, the fuel delivery system lacks flexibility in adjusting the fuel delivery volume. Under different operating conditions, it is difficult to accurately adjust the fuel delivery volume to meet the actual needs of the diesel engine. This not only affects the performance of the diesel engine but also causes unreasonable use of fuel to a certain extent. Therefore, this application proposes another technical solution to address this problem. Utility Model Content

[0004] The purpose of this utility model is to provide a single-sided fuel supply device for diesel engines in internal combustion locomotives, in order to solve the problem that in the existing technology, when the locomotive is idling or in other operating conditions, the diesel engine continuously supplies fuel to both cylinders, resulting in unnecessary fuel waste. For example, during maintenance operations or when the crew is eating, the diesel engine maintains a low speed, and the fuel supply from both sides at this time results in high fuel consumption, increasing operating costs. Moreover, the fuel delivery system lacks flexibility in adjusting the fuel delivery volume, making it difficult to accurately adjust the fuel delivery volume to meet the actual needs of the diesel engine under different operating conditions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a single-sided fuel supply device for a diesel engine of an internal combustion locomotive, comprising a high-pressure air source, wherein a fuel supply control mechanism is provided on one side of the high-pressure air source;

The high-pressure air source, the single-sided fuel supply solenoid valve, the drive cylinder, the fuel injection pump, and the diesel engine body are all electrically connected to an electronic control module.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This diesel locomotive's single-sided fuel supply device uses an electronic control module to control a single-sided fuel supply solenoid valve to cut off the high-pressure airflow to the drive cylinder, stopping fuel supply to one side of the injection pump and achieving single-sided fuel supply. This significantly reduces fuel consumption and saves operating costs. A pressure sensor constantly monitors the high-pressure air pressure in the intake pipe and feeds the data back to the electronic control module to ensure stable operation of the device.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1-3 A single-sided fuel supply device for a diesel engine of an internal combustion locomotive includes a high-pressure air source 1, and a fuel supply control mechanism is provided on one side of the high-pressure air source 1.

[0023] The oil supply control mechanism includes an intake pipe 2 fixedly connected to one side of the high-pressure air source 1. A pressure sensor 3 is installed on the outside of the intake pipe 2. The pressure sensor 3 is a high-precision strain gauge sensor. A single-sided oil supply solenoid valve 201 is fixedly installed on the right side of the intake pipe 2. A delivery pipe 4 is fixedly installed on one side of the single-sided oil supply solenoid valve 201. A drive cylinder 5 is fixedly connected to one side of the delivery pipe 4. The intake pipe 2 and the single-sided oil supply solenoid valve 201 are connected through a sealing joint. The delivery pipe 4, the single-sided oil supply solenoid valve 201, and the drive cylinder 5 are all connected by threads, which facilitates connection and fixation.

[0024] Among them, the left side of the drive cylinder 5 is fixedly installed with the fuel injection pump 6, the side of the fuel injection pump 6 is fixedly connected with the fuel supply pipe 7, the side of the fuel supply pipe 7 is fixedly connected with the diesel engine body 8, the high pressure air source 1, the single-sided fuel supply solenoid valve 201, the drive cylinder 5, the fuel injection pump 6 and the diesel engine body 8 are all electrically connected to the electronic control module 101, which consists of a power supply, a display screen, an operation panel and an alarm.

[0025] In embodiment two, a conveying adjustment assembly is provided on the outside of the oil pipeline 7. The conveying adjustment assembly includes an installation box 9 fixedly installed on the top of the oil pipeline 7. A stepper motor 10 is fixedly installed on the top of the installation box 9. A threaded rod 11 rotatably connected to the installation box 9 is fixedly installed on the output shaft of the stepper motor 10. A threaded block 12 is threadedly connected to the outside of the threaded rod 11. A threaded groove is opened inside the threaded block 12. The threaded block 12 is threadedly connected to the threaded rod 11 through the threaded groove, which helps the threaded block 12 to move on the outside of the threaded rod 11.

[0026] Among them, the threaded block 12 is fixedly installed on both the left and right sides with limiting blocks 13 that are slidably connected to the mounting box 9. The bottom of the threaded block 12 is fixedly installed with a sealing cylinder 14 that is slidably connected to the oil pipeline 7. The top of the oil pipeline 7 is provided with a movable groove. The sealing cylinder 14 is movably connected to the oil pipeline 7 through the movable groove, so that the sealing cylinder 14 can be raised and lowered to adjust the internal space of the oil pipeline 7.

[0027] When the diesel engine is running normally, the electronic control module 101 controls the high-pressure air source 1, the single-sided fuel supply solenoid valve 201 and other components to be in normal working state. The high-pressure air source 1 generates high-pressure air, which is delivered through the intake pipe 2. The pressure sensor 3 monitors the pressure of the high-pressure air in the intake pipe 2 in real time and transmits the signal to the electronic control module 101. At this time, the single-sided fuel supply solenoid valve 201 opens, and the high-pressure air enters the drive cylinder 5 through the delivery pipe 4. However, the drive cylinder 5 does not affect the normal operation of the fuel injection pump 6. The fuel injection pump 6 supplies fuel to both sides of the diesel engine body 8 through the fuel supply pipe 7. The cylinders on both sides of the diesel engine body 8 operate normally. When the diesel engine enters the idling state, the electronic control module 101 receives the idling signal and controls the single-sided fuel supply solenoid valve 201 to act, cutting off the air path of the high-pressure air to the drive cylinder 5. The drive cylinder 5 acts, causing the fuel injection pump 6 connected to it to stop supplying fuel on one side, realizing single-sided fuel supply to the diesel engine and reducing fuel consumption.

[0028] If it is necessary to adjust the amount of oil supplied, the electronic control module 101 can be operated to make the delivery adjustment component on the outside of the oil supply pipe 7 work. The stepper motor 10 starts, and its output shaft drives the threaded rod 11 to rotate in the mounting box 9. Since the threaded block 12 is threadedly connected to the threaded rod 11 through the internal thread groove, and the limit blocks 13 on the left and right sides slide in the mounting box 9, the threaded block 12 is restricted to only move up and down. The sealing cylinder 14 at the bottom of the threaded block 12 rises and falls in the movable groove at the top of the oil supply pipe 7, thereby adjusting the internal space of the oil supply pipe 7 and realizing the control of the amount of oil supplied. When the idle signal disappears, the electronic control module 101 controls the single-sided oil supply solenoid valve 201 to restore the air path, and the diesel engine restores the dual-sided oil supply.

[0029] In summary, the single-sided fuel supply device for the diesel engine of this internal combustion locomotive uses an electronic control module 101 to control a single-sided fuel supply solenoid valve 201 to cut off the high-pressure air supply to the drive cylinder 5, thus stopping fuel supply to one side of the fuel injection pump 6 and achieving single-sided fuel supply. This significantly reduces fuel consumption and saves operating costs. The pressure sensor 3 constantly monitors the high-pressure air pressure in the intake pipe 2 and feeds the data back to the electronic control module 101 to ensure stable operation of the device. When it is necessary to adjust the fuel delivery volume, the electronic control module 101 is activated to start the delivery adjustment component. The stepper motor 10, threaded rod 11, threaded block 12, and sealing cylinder 14 work together to flexibly adjust the internal space of the fuel delivery pipe 7 and accurately control the fuel delivery volume. In addition, when the idle signal disappears, the electronic control module 101 controls the single-sided fuel supply solenoid valve 201 to restore the air supply, and the diesel engine quickly resumes dual-sided fuel supply, ensuring smooth operation of the locomotive under different operating conditions.
