An oil heating apparatus 10 for an engine according to an embodiment of the present invention will be described in detail with reference to fig. 1 to 2.
Referring to fig. 1 to 2, an oil heating apparatus 10 for an engine according to an embodiment of the present invention includes: the exhaust pipe 1 is communicated with an oil heating manifold 2, the exhaust pipe 1 is communicated with an exhaust port of the engine, the oil heating manifold 2 is suitable for being communicated with the exhaust pipe 1, namely, the oil heating manifold 2 suitable for being communicated with the exhaust pipe 1 is arranged on one side of the exhaust pipe 1 of the engine, and the oil heating manifold 2 is positioned close to an oil pan 4 of the engine.
Therefore, when the engine works, when the exhaust gas exhausted by the engine is exhausted to the outside through the exhaust pipe 1, part of the exhaust gas can flow through the oil heating manifold 2, and because a large amount of heat exists in the exhaust gas, the oil heating manifold 2 is positioned at the position close to the oil pan 4 of the engine, therefore, the heat of the exhaust gas flowing through the oil heating manifold 2 can be partially transferred to the oil pan 4, so that the oil in the oil pan 4 can be heated, further, the fuel in the oil pan 4 can be volatilized, the oil in the oil pan 4 is ensured not to be increased, and the oil increase is prevented.
Wherein, the engine oil heating manifold 2 can be communicated with the exhaust pipe 1 and can be closed, so that the oil pan 4 can be selectively heated, in a specific embodiment, when the engine is cold started or is in a low ambient temperature condition, if the load of the engine is enough and the temperature of the engine oil in the oil pan 4 is low, at this time, because the amount of fuel oil sprayed by the engine is large, the possibility of the fuel oil falling into the oil pan 4 is high, therefore, the engine oil heating manifold 2 is communicated with the exhaust pipe 1, the engine oil in the oil pan 4 can be heated, thereby effectively heating the fuel oil dropping into the oil pan 4, further volatilizing the fuel oil, not only preventing the engine oil from emulsifying and deteriorating due to the increase of the engine oil and ensuring the quality of the engine oil, but also being beneficial to improving the temperature rising speed of the engine due to the temperature rise of the engine oil, and the emission pollution of the engine is reduced.
It should be noted that the fuel in the present application refers to a fuel that can be volatilized by heating, such as gasoline.
According to the oil heating device 10 for the engine of the embodiment of the invention, the oil heating manifold 2 of the oil heating device 10 is suitable for being communicated with the exhaust pipe 1, and the oil heating manifold 2 is positioned close to the oil pan 4, so that when the engine is in cold start or under the condition of low ambient temperature, the oil heating manifold 2 can be communicated with the exhaust pipe 1, and therefore, part of exhaust gas in the exhaust pipe 1 can flow through the oil heating manifold 2, so that the oil heating manifold 2 can heat the oil in the oil pan 4, further the fuel in the oil pan 4 is volatilized, the oil in the oil pan 4 is ensured not to be increased, the oil increase is prevented, and the temperature rising speed of the engine is increased due to the temperature rising of the oil, and the emission pollution of the engine is reduced.
Further, as shown in fig. 2, a heating intake port 11 and a heating exhaust port 12 are provided on the exhaust pipe 1, one end of the engine oil heating manifold 2 is communicated with the heating intake port 11, and the other end is communicated with the heating exhaust port 12, that is, when the engine oil heating manifold 2 is communicated with the exhaust pipe 1, the exhaust gas entering the engine oil heating manifold 2 from the heating intake port 11 also flows back into the exhaust pipe 1 from the heating exhaust port 12, thereby preventing the exhaust gas in the engine oil heating manifold 2 from being discharged unintentionally.
Furthermore, an on-off control device is arranged on the engine oil heating manifold 2 and is suitable for controlling the connection and the disconnection between the engine oil heating manifold 2 and the exhaust pipe 1.
Therefore, by controlling the on-off control means, the oil heating manifold 2 and the exhaust pipe 1 can be communicated when the oil pan 4 needs to be heated, and can be closed when the oil pan 4 does not need to be heated.
It should be noted that, when the engine has a certain load and the temperature of the engine oil in the oil pan 4 is low, at this time, the engine is generally in a cold start state or under the condition of low ambient temperature, the cylinder wall of the engine is prone to "wet wall", so that the engine oil in the oil pan 4 is heated by communicating the engine oil heating manifold 2 with the exhaust pipe 1, and the fuel oil dropping in the oil pan 4 can be volatilized quickly.
The on-off control device is used for closing the space between the engine oil heating manifold 2 and the exhaust pipe 1, and the requirement that the temperature of the engine oil in the oil pan 4 is enough, no matter how much the load of an engine exists, the temperature of the engine oil is enough to heat and volatilize fuel oil dropping in the oil pan 4, so that the condition of 'engine oil increase' can be guaranteed, the engine oil is prevented from losing efficacy due to overhigh temperature of the engine oil, and the quality of the engine oil is guaranteed to be good by closing the engine oil heating manifold 2 and the exhaust pipe 1. And, when the temperature of the oil in the oil pan 4 is low and the load of the engine is low, the power of the engine is low at this time, and the amount of injected oil of the engine is small, so that the fuel does not drip into the oil pan 4, and it is also unnecessary to communicate the oil heating manifold 2 with the exhaust pipe 1.
Further, as shown in fig. 1 to 2, the on/off control means may include: the active control valve 31 is located near the heating intake port 11, and the passive control valve 33 is located near the heating exhaust port 12.
By providing the active control valve 31 and the passive control valve 33 at the heating intake port 11, it is possible to accurately control the communication and the closing between the oil heating manifold 2 and the exhaust pipe 1.
The active control valve 31 is an electronic control valve, the passive control valve 33 is a mechanical control valve, and the engine ECU is electrically connected with the active control valve 31;
the active control valve 31 and the passive control valve 33 are formed as follows: when the engine load is not less than the preset load threshold value and the temperature of the engine oil in the oil pan is lower than the preset temperature threshold value, the engine ECU controls the active control valve 31 to be opened, and when the pressure value in the engine oil heating manifold 2 is not less than the preset pressure threshold value, the passive control valve 33 is opened.
That is to say, whether the active control valve 31 works or not is controlled by the engine ECU, wherein the engine ECU detects the load of the engine and detects the temperature of the engine oil in the oil pan 4, when it is detected that the load of the engine is not less than the preset load threshold and the temperature of the engine oil in the oil pan 4 is lower than the preset temperature threshold, the engine ECU controls the active control valve 31 to open, the exhaust gas enters the engine oil heating manifold 2 from the active control valve until the pressure of the exhaust gas in the engine oil heating manifold 2 reaches the preset pressure threshold, which indicates that the amount of the exhaust gas in the engine oil heating manifold 2 is enough, so that the engine oil heating manifold 2 can be heated quickly, the temperature of the engine oil in the oil pan 4 is quickly increased, the quality of the engine oil is ensured to be good, and the. And is then opened by the control valve 33 to discharge the exhaust gas in the oil heating manifold 2 into the exhaust pipe 1.
And by arranging the controlled valve 33 at the heating exhaust port 12, the tightness between the engine oil heating manifold 2 and the exhaust pipe 1 can be ensured to be better when the engine oil heating manifold 2 and the exhaust pipe 1 are closed, and the working reliability of the engine oil heating device 10 is ensured to be high.
Specifically, as shown in fig. 1 to 2, the opening and closing control device further includes: and a booster pump 32, the booster pump 32 being located on the oil heating manifold 2 between the active control valve 31 and the passive control valve 33.
The booster pump 32 is an electronic booster pump, the engine ECU is electrically connected to the booster pump 32, and the booster pump 32 is formed such that: when the active control valve 31 is opened, the engine ECU controls the booster pump 32 to operate.
Set up booster pump 32 on machine oil heating manifold 2, can accelerate the speed that waste gas enters into in machine oil heating manifold 2 to guarantee that machine oil heating manifold 2 can be very fast heat oil pan 4, and then guarantee that the fuel can volatilize fast.
In an exemplary embodiment, the boost pump 32 may be located close to the active control valve 31, so that the inlet may boost the exhaust gas to the oil heating manifold 2 in time, thereby ensuring high efficiency of the oil heating apparatus 10.
Further, the exhaust pipe 1 communicates with a catalyst 5.
