Description

Technical Field

[0001] This invention relates to the field of automotive engine auxiliary starting technology, specifically to a device for low-temperature, wear-free starting of automotive engines, particularly suitable for cold start protection of automotive engines in cold climates and other low-temperature environments. Background Technology

[0002] During normal engine operation, lubricating oil (engine oil) plays a crucial role in lubrication and heat dissipation. The oil film it forms on the surfaces of various moving parts effectively isolates direct metal-to-metal contact, reducing friction loss and heat generation. When the engine stops working, the engine oil gradually drains back into the oil pan under gravity. Although the engine has multiple oil check valves to slow down the backflow, the oil film in various lubrication points will basically disappear as the downtime increases. Especially in cold winter regions, where the ambient temperature often drops below -20°C and can even reach -40°C in extreme cases, the viscosity of the engine oil will increase exponentially, and its fluidity will decrease significantly. The effect of the oil check valves in slowing down the backflow will be further weakened. The oil film in core lubrication points such as crankshaft main bearings, connecting rod bearings, and camshaft tappet and pushrod contact surfaces will basically break down after 1-2 hours of downtime. If the downtime exceeds 8 hours, the oil film will almost completely disappear. When the engine is started again, the moving parts will be in a state of dry friction without oil film protection at the moment of starting. The dry friction time of only 0.5-1 second may cause scratches and wear on the metal surface. Long-term accumulation will significantly shorten the service life of the engine and even lead to failures such as abnormal bearing noise and cylinder wall scoring.

[0003] To address the aforementioned problems, some auxiliary devices have emerged in the prior art, but they generally suffer from significant drawbacks:

[0004] Firstly, the oil heating efficiency is low. For example, some devices only have a single heating rod at the bottom of the oil pan, which uses the oil to flow and heat at the same time. This results in a large heating power requirement (usually more than 300W) and a long heating time. It takes more than 30 minutes of continuous heating to reduce the overall oil viscosity to a reasonable range, which is not only time-consuming but also consumes additional battery power.

[0005] Secondly, the oil passage is not fully filled. The output pressure of some auxiliary oil pumps can only meet the oil passage filling from the oil pan to the main oil passage inlet. For the small-diameter oil passages from the main oil passage branch to the camshaft and turbocharger, the oil cannot be effectively delivered, resulting in these key components being in an oil-free lubrication state at the moment of startup.

[0006] Third, the oil pressure builds up slowly during startup. The existing device has not optimized the oil circuit design, and the oil needs to flow through multiple bends in the pipeline, resulting in a large pressure loss. It still takes 2-3 seconds for the main oil passage to reach effective lubrication pressure, which cannot completely avoid the risk of dry friction in the early stage of startup.

[0007] Furthermore, existing technologies lack specific protection for high-speed rotating components such as turbochargers that rely on oil lubrication and cooling. Turbochargers operate at speeds of up to 100,000-200,000 rpm, requiring far more oil for lubrication and cooling than ordinary components. Existing auxiliary devices do not have dedicated oil supply paths designed for their lubrication channels. Even if pressure is established in the main oil passage, it takes a long time for the oil to reach the turbocharger's lubrication chamber. The brief lack of oil during the initial startup can cause severe wear on the turbine shaft and floating bearing, leading to abnormal noise, reduced efficiency, or even premature failure of the turbocharger. This technology cannot fundamentally solve the problem of dry friction wear during engine cold starts in low-temperature environments. Summary of the Invention

[0008] In view of the shortcomings of existing technologies, such as insufficient lubrication, severe dry friction wear, and poor starting during low-temperature cold starts of engines, as well as the lack of pre-lubrication protection for key components such as turbochargers before starting, and the technical defects of traditional heating rods with high heating power and long heating time, this invention provides a low-temperature wear-free pre-start device for automobile engines. It uses a core component heating chamber to replace traditional heating rods, realizing pre-heating and pre-pressurization of engine oil before starting, ensuring the formation of an effective oil film in each lubrication part, reducing cold start wear, and improving engine starting smoothness and durability.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] A device for low-temperature, wear-free starting of an automobile engine includes an oil pan (18), a main oil passage distribution mechanism (13), an oil pressure sensor (4), and a pressure lubrication component, which comprises a crankshaft connecting rod mechanism (14), a camshaft valve train mechanism (15), a piston cooling nozzle (16), and a timing chain tensioner (17). The device is characterized by:

[0011] It also includes a pre-start oil supply heating control section, which includes a three-way adapter (1), a one-way valve (2), a motor oil pump (3), a heating distributor (6), a heating chamber (7), a first delay switch (8), a second delay switch (19), a car 12V power supply (9), a remote control receiver (10), a buzzer (11), and an oil dipstick sleeve (12);

[0012] One end of the three-way adapter (1) is connected to the interface of the oil pressure sensor (4), and the other end is connected to the motor oil pump (3) through the oil supply pipe (5). The one-way valve (2) is connected in series on the oil supply pipe (5) between the motor oil pump (3) and the three-way adapter (1).

[0013] The heating distributor (6) has an installation interface on its side and a manual gear adjustment knob (including neutral, gear 1, and gear 2) on its top. It also has circuit connection terminals inside. The heating chamber (7) has a heating chamber inlet (71) on the lower part of one side and a heating chamber outlet (72) on the upper part of the opposite side. It has a heating unit (73) inside. The heating chamber (7) has a volume of 300-350 ml and is made of metal or hard plastic, forming a closed heating space. The heating distributor (6) is electrically connected to the heating unit (73) inside the heating chamber (7) through the circuit connection terminals to achieve heating control.

[0014] The oil dipstick sleeve (12) mates with the existing engine oil dipstick, and the heating chamber inlet (71) of the heating chamber (7) is connected through... The oil supply pipe (5) is connected to the oil dipstick sleeve (12), and the connection is sealed. The heating chamber outlet (72) of the heating chamber (7) is connected through... The oil pipeline (5) is connected to the oil inlet of the motor oil pump (3);

[0015] The 12V power supply (9) of the car is electrically connected to the motor oil pump (3), the heating unit (73) of the heating chamber (7), the first delay switch (8), the second delay switch (19), the remote control receiver (10), and the buzzer (11) through the circuit respectively; the remote control receiver (10) is connected in parallel to the control circuit, the first delay switch (8) is connected in series to the power supply circuit of the heating unit (73) of the heating chamber (7), the second delay switch (19) is connected in series to the power supply circuit of the motor oil pump (3), and the buzzer (11) is electrically connected to the power supply circuit;

[0016] The main oil passage distribution mechanism (13) is connected to the three-way adapter (1) and is used to distribute the oil to each pressure lubrication component.

[0017] Furthermore, the gear knob of the heating distributor (6) can switch between neutral, gear 1 and gear 2 modes. Neutral is a non-powered state, used for filling with oil when working for the first time; gear 1 is a normal heating mode, which raises the oil temperature in the heating chamber (7) by 10-15°C; gear 2 is a high-heat mode, which raises the oil temperature in the heating chamber (7) by 20°C.

[0018] Furthermore, the first delay switch (8) is used to control the heating time of the heating unit (73) of the heating chamber (7), which is set to 30 to 50 seconds to ensure that the oil is heated to a state of excellent fluidity; the second delay switch (19) is linked with the first delay switch (8) and automatically turns on after the first delay switch (8) completes the timing, driving the motor oil pump (3) to work; the total automatic power-off time of the first delay switch (8) and the second delay switch (19) is 20 to 30 seconds (starting from the start of the engine), and the power-off time can be set as needed.

[0019] Furthermore, the effective control range of the remote control receiver (10) is 10 meters.

[0020] Furthermore, the buzzer (11) emits an audible alert when the device starts oil heating and stops audibly when the device is powered off.

[0021] Furthermore, the motor oil pump (3) is a miniature high-pressure oil pump with a rated pressure that matches the engine's main oil passage pressure requirements; the heating power of the heating unit (73) in the heating chamber (7) is 100 to 200 watts, which is significantly lower than that of traditional heating rods, and the heating is concentrated and fast.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] (1) Significantly reduce cold start wear: Before starting, the oil is heated statically and centrally through the heating chamber (7). The oil can reach excellent fluidity in 30 to 50 seconds. Then, it is pre-pressurized and delivered to key lubrication parts such as crankshaft connecting rod mechanism and camshaft valve train mechanism to form an effective oil film, completely avoiding dry friction at the moment of cold start and significantly extending the service life of the engine.

[0024] (2) Protect the reliability of key components: For high-speed rotating components such as turbochargers, ensure that the engine oil is quickly in place at the moment of start-up to avoid dry friction due to lack of oil, thereby improving the reliability and service life of key components;

[0025] (3) Improved low-temperature starting performance: The viscosity of the heated oil is reduced and its fluidity is improved, which shortens the oil pressure build-up time of the main oil passage distribution mechanism, reduces motion resistance, makes the engine start more smoothly, and reduces the load on the starter and battery.

[0026] (4) High heating efficiency and low energy consumption: The heating chamber (7) has a small volume (300-350ml), the oil is still and does not flow, the heating is concentrated, and the power of the heating unit (73) is only 100-200 watts. Compared with traditional heating rods (300W or more), the energy consumption is reduced, and the heating time is shortened from more than 30 minutes to 30-50 seconds, which greatly improves the ease of use.

[0027] (5) Convenient and flexible operation: It supports operation within 10 meters via remote receiver, and the heating level can be manually adjusted via heating distributor (neutral, level 1, level 2). The power-off time of the delay switch can be set to adapt to different low-temperature environments and usage habits.

[0028] (6) High safety: It is equipped with a buzzer to indicate, a dual delay switch to realize orderly control of heating and oil supply, a one-way valve to prevent oil backflow, and a sealing treatment at the connection between the heating chamber inlet (71) of the heating chamber (7) and the oil dipstick sleeve (12). The structural design is safe and reliable and does not affect the original operating logic of the engine.

[0029] (7) Strong adaptability: It can be widely used in the most popular family cars. During installation, it is connected to the original engine oil circuit and electrical circuit through components such as three-way adapter. It requires little modification, has good compatibility, and the oil dipstick sleeve does not affect daily oil testing. Attached Figure Description

[0052] Device operation process

[0053] Before starting the engine in a low-temperature environment (ambient temperature ≤ 0℃), the device operates in three stages:

[0054] First stage (oil filling): The user adjusts the gear knob of the heater distributor (6) to neutral (no power supply) and sends a start signal through the remote transmitter within a 10-meter range. After receiving the signal, the remote receiver (10) turns on the power supply circuit of the motor oil pump (3), and the motor oil pump (3) starts, pumping the oil in the oil pan (18) through the dipstick sleeve (12). The oil pipe (5) is drawn into the heating chamber inlet (71) of the heating chamber (7) until the heating chamber (7) is completely filled; after filling is completed, the remote control signal is turned off and the motor oil pump (3) stops working. Due to the action of the one-way valve (2), the oil in the heating chamber (7) will not flow back and will remain full of oil.

[0055] Second stage (centralized heating): The user adjusts the gear knob on the top of the heating distributor (6) according to the ambient temperature: select gear 1 when the ambient temperature is between -10℃ and 0℃, and select gear 2 (high heat mode) when the ambient temperature is below -10℃; press the start button of the remote transmitter again, and the remote receiver (10) will receive the signal and turn on the heating circuit. The car 12V power supply (9) supplies power to the heating unit (73) of the heating chamber (7) through the first delay switch (8). The buzzer (11) emits a prompt sound. At this time, the second delay switch (19) is in the closed state, and the motor oil pump (3) does not work; the oil in the heating chamber (7) is still and does not flow, and is heated in a concentrated manner. The heating power of 100 to 200 watts can heat the oil to a state with excellent fluidity within 30 to 50 seconds.

[0056] The third stage (pressurized oil supply and automatic stop): After the first delay switch (8) completes the 30-50 second heating timer, the second delay switch (19) is automatically triggered to open, and the motor oil pump (3) starts to pressurize the heated oil in the heating chamber (7) (pressure 0.2-0.3MPa), and then sequentially passes it through the heating chamber outlet (72). The oil supply pipe (5), one-way valve (2), and three-way adapter (1) enter the main oil passage distribution mechanism (13), quickly filling all lubricating oil passages and forming an effective oil film on the surfaces of key components such as crankshaft connecting rod mechanism (14), camshaft valve train mechanism (15), and turbocharger. After the user starts the engine, the first delay switch (8) and the second delay switch (19) start to accumulate time. After reaching the set time of 20 to 30 seconds, the circuit is automatically cut off, the motor oil pump (3) and the heating unit (73) of the heating chamber (7) stop working, the buzzer (11) stops prompting, and the engine enters normal operation.
