Description
Technical Field
The invention relates to the technical field of automobile engine control, in particular to a spark plug and a hydrogen engine deicing control method for a vehicle.
Background
The fuel of the hydrogen engine is pure hydrogen, and the product of the fuel after combustion is basically water, so that residual water vapor in a cylinder after shutdown is very easy to condense on the surface of a combustion inner wall surface, especially a spark plug, in the process of gradually reducing the temperature of the engine under the extremely low temperature environment, for example, when the temperature is lower than 0 ℃, condensed liquid water can freeze, so that the spark plug cannot be effectively ignited when the hydrogen engine is in low-temperature cold start, and the problem of difficult cold start is caused. At present, a hydrogen engine does not have a low-temperature environment cold-start spark plug quick deicing device, but in the field of similar natural gas engines, before the engine is shut down, an ECU controls a throttle valve to be fully opened to realize the operation of quickly discharging residual water vapor in an engine cylinder, and through the operation of scavenging in the cylinder, the water vapor residue in the cylinder can be reduced, and the phenomenon that the residual water vapor freezes on a spark plug under the low-temperature condition is avoided. However, the operation of in-cylinder scavenging can only be applied in certain situations; for example, when the ambient temperature is higher than zero degrees centigrade and higher than the set ambient temperature threshold value, the engine is directly stopped, and a certain amount of saturated water vapor is still contained in the cylinder. However, since the ambient temperature varies periodically during the day, as the ambient temperature gradually decreases, the temperature gradually falls below the temperature threshold, two strategies are considered: firstly, after the temperature is lower than the temperature threshold value, the ECU is powered off at the moment, and the engine cannot be controlled to enter a scavenging mode again, so that the anti-icing method fails; secondly, after the temperature is lower than the temperature threshold value, because the ECU is always in the electrified state and continuously feeds back the signal of the temperature sensor until the engine is restarted and enters a scavenging mode, at the moment, because the ECU is electrified for a long time, the electric quantity of the storage battery is easily and rapidly lost, and the problem of restart failure possibly exists.

Example two
Referring to fig. 2, an embodiment of the present invention provides a method for controlling deicing of a hydrogen engine of a vehicle, the hydrogen engine using a spark plug according to any one of the embodiments, the method including:
s1: detecting a current ambient temperature after the vehicle is unlocked and powered on;
after the vehicle is electrified, the temperature sensor is adopted to detect the current ambient temperature, so that the real-time property of the detected ambient temperature can be ensured.
S2: and when the environmental temperature is lower than a preset icing temperature threshold, introducing alternating current to the coil winding so as to heat the central electrode to finish the deicing operation of the spark plug.
Wherein the freezing temperature threshold may be set to an initial value of 0 degrees celsius. After the vehicle is unlocked and powered on, the current environment temperature is detected through the temperature sensor, when the environment temperature is lower than the freezing temperature threshold value, alternating current is introduced into a coil winding of the spark plug, and due to the electromagnetic induction effect, eddy current is generated inside the center electrode, so that the center electrode is heated up rapidly, the deicing operation is realized, the problem of difficult ignition caused by freezing of the surface of the spark plug of a hydrogen engine in a low-temperature environment is solved, and the starting failure of the hydrogen engine is avoided.
In an alternative embodiment, the vehicle is provided with a coil control unit; wherein, after the vehicle is unlocked, the triggering time of the coil control unit for electrifying is earlier than the triggering time of the ECU of the vehicle for electrifying;
then, when the ambient temperature is less than a preset freezing temperature threshold, passing an alternating current through the coil winding, including:

or when the ambient temperature is greater than or equal to the freezing temperature threshold value, controlling the hydrogen engine to start through the ECU.
For example, the spark plug deicing control may be performed by a separate coil control unit or the ECU of the vehicle after the vehicle is unlocked. When the ECU or the whole vehicle is electrified, the temperature sensor feeds the detected ambient temperature back to the ECU or the coil control unit, the ECU or the coil control unit judges whether the ambient temperature is lower than an icing temperature threshold value or not, if the ambient temperature is higher than the icing temperature threshold value, the ECU directly controls the ignition module to generate high voltage and output the high voltage to the spark plug, the spark plug normally trips, and the engine enters a starting state; if the environmental temperature is lower than the freezing temperature threshold, the ECU or the coil control unit controls a coil winding of the spark plug to be electrified and generate alternating current, eddy current can be generated inside the columnar central electrode under the action of electromagnetic induction, so that the deicing operation is realized after the central electrode is quickly heated, then the ECU controls the ignition module to generate high voltage, the spark plug is ignited, and the engine enters a starting state; therefore, the problem of difficult ignition caused by icing on the surface of the spark plug of the hydrogen engine in a low-temperature environment is avoided, and the failure of starting the hydrogen engine is avoided.
As shown in fig. 3, a flow chart of the coil control unit controlling the deicing operation is given. The coil winding of the spark plug is subjected to power-on control by adopting the independent coil control unit, namely, the temperature sensor inputs the detected ambient temperature into the coil control unit instead of an ECU (electronic control unit), because the coil control unit can trigger power-on operation when the whole vehicle is unlocked, the power-on operation can be advanced compared with the power-on operation of the ECU, sufficient time is reserved for preheating and deicing of the center electrode, and the deicing effect is improved.
In an optional embodiment, the method further comprises:
detecting the ambient air pressure of the current location of the vehicle to which the hydrogen engine belongs;
and correcting the icing temperature threshold according to the ambient air pressure.
The higher the ambient air pressure, the lower the freezing temperature. Therefore, the icing temperature threshold can be corrected according to the local ambient air pressure, so that the vehicle is prevented from starting the deicing operation by mistake.
Compared with the prior art, the embodiment of the invention has the beneficial effects that:
1. after the vehicle is unlocked and powered on, when the ambient temperature is lower than the freezing temperature threshold, alternating current is introduced into a coil winding of the spark plug, and due to the electromagnetic induction effect, eddy current is generated inside the center electrode, so that the center electrode is quickly heated, the deicing operation is realized, scavenging action is not required to be carried out after the engine is stopped, and the driving experience is improved.
2. The method can ensure that the surface of the spark plug is deiced at an extremely low temperature, and avoid the problems of poor spark plug sparking and failed starting of the hydrogen engine caused by icing on the surface of the spark plug.
3. After the temperature of the central electrode is increased, the temperature gradient between the high-temperature plasma in the electrode gap and the electrode body can be reduced, the heat transfer loss from the plasma to the electrode is reduced, the heating energy ratio of the mixed gas is increased, and the starting process is improved.
