Description

Technical Field

[0001] The invention relates to the technical field of engines, in particular to an engine cylinder head cover. Background Art

[0002] The cylinder head cover of the engine is located at the top of the engine. Its main function is to prevent foreign matter from entering the engine and to seal it. Inside the cylinder head cover are engine rocker arms, valves, camshafts and other parts that are running at high speeds, which will generate a lot of oil particles and oil mist that will splash onto the cylinder head cover.

[0003] When the engine is burning, some gas will leak out of the combustion chamber and eventually be discharged outside the engine through the oil pan, cylinder head cover, and breather. At present, the new emission regulations require the crankcase ventilation to be connected to the engine intake to avoid the emission of pollutants. The exhaust gas produced by engine combustion contains a small amount of water vapor. If the fuel is natural gas, more water vapor will be produced. In cold weather, this water vapor will condense on the top of the cylinder head cover where the temperature is lower. The oil particles and oil mist produced by the engine contact and mix with these condensed water to form oil emulsions. The emulsified oil enters the oil-gas separator, supercharger and intercooler through the crankcase ventilation system. When there is a lot of emulsified oil, it is very easy to block the crankcase ventilation system, resulting in high crankcase pressure and oil leakage. At the same time, the oil emulsion will also contaminate the supercharger, intercooler, etc., affecting the normal operation of the engine.

[0004] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0005] The object of the present invention is to provide an engine cylinder head cover, which has a simple and reasonable structure and prevents water vapor in the engine from generating condensed water and oil emulsion on the inner wall of the cylinder head cover, thereby ensuring the normal operation of the engine.

[0006] To achieve the above-mentioned purpose, the present invention provides an engine cylinder head cover, comprising: a cylinder head cover body, an electric heating mechanism and a connector. The electric heating mechanism is evenly arranged on the four walls of the cylinder head cover body. The connector is arranged on one end of the cylinder head cover body, one end of the connector is electrically connected to the electric heating mechanism, and the other end of the connector is electrically connected to the ECU. The ECU can control the opening and closing of the heating mechanism.

[0007] In one embodiment of the present invention, the engine cylinder head cover further includes a temperature sensor electrically connected to the ECU, and the temperature sensor is used to detect the temperature of the cylinder head cover body in real time.

[0008] In one embodiment of the present invention, the electric heating mechanism is an electric heating wire.

[0009] In one embodiment of the present invention, when the temperature of the cylinder head cover body is lower than a first preset value, the ECU controls the electric heating mechanism to turn on, thereby heating the cylinder head cover body.

[0010] In one embodiment of the present invention, when the temperature of the cylinder head cover body is higher than a second preset value, the ECU controls the electric heating mechanism to be turned off.

[0011] Compared with the prior art, the engine cylinder head cover according to the present invention has a simple and reasonable structure, which prevents water vapor in the engine from generating condensed water and oil emulsion on the inner wall of the cylinder head cover, thereby ensuring the normal operation of the engine.

[0017] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.

[0018] Unless explicitly stated otherwise, throughout the specification and claims, the term “comprise” or variations such as “include” or “comprising”, etc., will be understood to include the stated elements or components but not to exclude other elements or components.

[0019] Figure 1 1 is a schematic diagram of a top view of an engine cylinder head cover according to an embodiment of the present invention. Figure 2 yes Figure 1 Schematic diagram of the cross-sectional structure at AA in the middle. Figure 3 The figure is a schematic structural diagram of an engine cylinder head cover installed on an engine according to an embodiment of the present invention.

[0020] like Figures 1 to 3As shown, an engine cylinder head cover according to a preferred embodiment of the present invention comprises: a cylinder head cover body 1, an electric heating mechanism and a connector 3. The electric heating mechanism is evenly arranged on the surrounding walls of the cylinder head cover body 1. The connector 3 is arranged on one end of the cylinder head cover body, one end of the connector 3 is electrically connected to the electric heating mechanism, and the other end of the connector 3 is electrically connected to the ECU 5. Among them, the ECU 5 can control the opening and closing of the heating mechanism.

[0021] In one embodiment of the present invention, the engine cylinder head cover further comprises a temperature sensor which is electrically connected to the ECU 5 , and the temperature sensor 6 is used to detect the temperature of the cylinder head cover body 1 in real time. The electric heating mechanism is an electric heating wire 2 .

[0022] In one embodiment of the present invention, when the temperature of the cylinder head cover body 1 is lower than a first preset value, the ECU 5 controls the electric heating mechanism to turn on, thereby heating the cylinder head cover body 1. When the temperature of the cylinder head cover body 1 is higher than a second preset value, the ECU 5 controls the electric heating mechanism to turn off.

[0023] In practical applications, the cylinder head cover of the engine of the present invention is uniformly provided with electric heating wires 2 (or other electric heating materials, the present invention is not limited thereto) on the surrounding walls of the cylinder head cover body 1, and the electric heating wires 2 are connected to the engine ECU5 through the connector 3. The ECU5 can control whether the electric heating wires 2 in the cylinder head cover body 1 are working and the degree of heating according to the data detected by the temperature sensor 6, the running state of the engine 4 and other information, thereby realizing the intelligent temperature control of the cylinder head cover body 1. When the temperature of the cylinder head cover body 1 is low and the engine 4 is in the state of just starting or low load working, the ECU5 controls the electric heating wires 2 in the cylinder head cover body 1 to work, so that the cylinder head cover body 1 is constant in a certain temperature range. When the engine 4 works for a long time and the temperature of the cylinder head cover body 1 is high, the electric heating wires 2 stop working. The water vapor generated by the combustion of the engine 4 will not condense when it encounters the hot cylinder head cover, but directly enters the crankcase ventilation system, thus avoiding the water vapor from generating condensed water and emulsified engine oil on the inner wall of the cylinder head cover.

[0024] In summary, the engine cylinder head cover of the present invention has a simple and reasonable structure, which prevents water vapor in the engine from generating condensed water and engine oil emulsion on the inner wall of the cylinder head cover, thereby ensuring the normal operation of the engine.
