The invention discloses a membrane-type high-pressure air spring completely wrapped with a sleeve. The membrane-type high-pressure air spring comprises an air bag assembly and the limiting sleeve. The air bag assembly comprises a spring upper end cover, an air bag and a piston which are sequentially connected. The air bag is wrapped with the limiting sleeve. One end of the limiting sleeve is open, and the other end of the limiting sleeve is used for being connected with a vehicle body. The spring upper end cover is located at the end, connected with the vehicle body, of the limiting sleeve and fixedly connected with the limiting sleeve. By the adoption of the membrane-type high-pressure air spring completely wrapped with the sleeve, the damage caused by interference with other portions of a suspension frame by the air bag is avoided, and meanwhile due to the fact that the bearing area is constant, the designability of the stiffness of the air spring is improved, the structure is compact, the bearing capacity is high, and the occupied space is small.

The invention discloses a control method of a double-discharge mode plasma igniter, including: a control method on a piston engine, specifically: a crankshaft position sensor judges the crankshaft position, and if the current crankshaft rotation angle does not reach the set value, continue Judgment; if the set value has been reached, the ECU will output a low-voltage discharge command to the power supply; after the power supply receives the discharge command, it will output a certain voltage U1 to the upper anode, which is recorded as time t1; at this time, the upper anode and the ground electrode are discharged. A dielectric barrier discharge is formed in the ionization space a, and the gas in the ionization space a is ionized into a non-equilibrium plasma, and then the ionized gas moves downward, and enters the ionization space b through the isolation area after Δt time; this method solves the problem of existing heat balance The plasma igniter has problems such as low ignition energy, poor ignition reliability, and low utilization rate of ignition energy.

A composite type HID electric arc tube comprises a discharge tube and two outlet tubes. The discharge tube is a composite type double-layer shell body, the casing of which is formed by blowing meltdown quartz glass or Bach quartz glass, and the inner side of which is coated with a semi-transparent polycrystal alumina(PCA) layer. The outlet tubes are made of the meltdown quartz glass or the Bach quartz glass. The insides of the two ends of the two outlet tubes close to an electric arc cavity body are partially coated with a polycrystal alumina layer. After being sintered at the high temperature, the electric arc tube adopts the method of sealing electrodes at two sections. The first sections of the outlet tubes internally coated with PCA adopt glass solders for sealing, and the second sections thereof adopt molybdenum foil press seal. The HID electric arc tube with the structure has the advantages of easy shaping of quartz glass electric tubes, good voltage resistant property, standardphysical dimension inside the PCA electric cavity body, high temperature resistance and strong sodium penetrability resistance. In addition, the electric arc tube can improve the HID, particularly, photochromic stability and light efficiency of MH light, and prolong the service life of the light.
