[0022] A cylinder head injector bushing testing tool for pressurizing two-valve cylinder heads includes an injector bushing 1, a first support plate 4, and a second support plate 6. The injector bushing 1 is an existing product and is not considered a technical protection point of this application; therefore, it will not be described in detail here. The first support plate 4 and the second support plate 6 support and position the injector bushing 1. A positioning groove 2 is formed on the surface of the injector bushing 1 for inserting a pin bolt 8. A bushing opening 3 is formed on the surface of the injector bushing 1 for installing a bushing cover 11. A first slot 5 is formed on the surface of the first support plate 4 for inserting the pin bolt 8. A second slot 7 is formed on the surface of the second support plate 6 for inserting the pin bolt 8. The surface of the support plate 4 is fitted with a pin bolt 8 for mounting the first support plate 4 and the second support plate 6 on the surface of the injector copper sleeve 1. The surface of the pin bolt 8 is fitted with a bolt washer 9 for dispersing pressure, preventing loosening, protecting the connection surface, and adapting to different working conditions. The surface of the pin bolt 8 is fitted with a nut 10 through a thread to fix the installation position of the pin bolt 8. The surface of the injector copper sleeve 1 is fitted with a copper sleeve cover 11 for mounting at the copper sleeve opening 3. The surface of the copper sleeve cover 11 is fixedly connected with an external threaded sleeve 12 for connecting the air nozzle 13. The surface of the external threaded sleeve 12 is fitted with an air nozzle 13 through a thread to connect the air source.

[0023] Furthermore, four sets of first slots 5 are evenly distributed on the surface of the first support plate 4, and four sets of pin bolts 8 are arranged. The four sets of first slots 5 are used to install the four sets of pin bolts 8. The pin bolts 8 are connected to the surface of the first support plate 4 through the first slots 5, and the pin bolts 8 are installed on the surface of the first support plate 4 through the first slots 5.

[0024] Furthermore, the bolt washers 9 are in four sets. The bolt washers 9 are connected to the surface of the first support plate 4 by the abutting connection between the bolt pin 8 and the surface of the first support plate 4. The bolt washers 9 are fitted onto the surface of the bolt pin 8, and then the bolt pin 8 is installed on the surface of the first support plate 4, so that the bolt washers 9 abut against the surface of the first support plate 4.

[0025] Furthermore, the positioning grooves 2 are evenly distributed in four groups on the surface of the injector copper sleeve 1. The pin bolts 8 are inserted and connected to the surface of the injector copper sleeve 1 through the positioning grooves 2. The first support plate 4 is connected to the surface of the injector copper sleeve 1 through the pin bolts 8. Then, the first support plate 4 is installed at the front end of the injector copper sleeve 1, so that the pin bolts 8 are inserted into the positioning grooves 2 until the first support plate 4 is close to the surface of the injector copper sleeve 1.

[0026] Furthermore, the second support plate 6 is in four groups, and the pin bolt 8 is connected to the surface of the second support plate 6 by inserting through the second slot 7. The second support plate 6 is connected to the surface of the injector copper sleeve 1 by abutting through the pin bolt 8. Then, the second support plate 6 is installed at the rear end of the injector copper sleeve 1, so that the pin bolt 8 passes through the positioning groove 2 from the second slot 7.

[0027] Furthermore, the nuts 10 are in four groups. The nuts 10 are connected by the abutting of the surfaces of the pin bolts 8 and the second support plate 6. The pin bolts 8 are fixedly connected to the surfaces of the injector copper sleeve 1 through the nuts 10. Then, the four groups of nuts 10 are tightened in sequence on the surfaces of the four groups of pin bolts 8, thereby fixing the first support plate 4 and the second support plate 6 to the front and rear end surfaces of the injector copper sleeve 1. Then, the injector copper sleeve 1 is placed in a water basin, so that most of the injector copper sleeve 1 is submerged in water.

[0028] Furthermore, the copper sleeve cover 11 is connected to the surface of the injector copper sleeve 1 by the copper sleeve opening 3, and the air nozzle 13 is fixedly connected to the surface of the copper sleeve cover 11 by the external threaded sleeve 12. Then, the copper sleeve cover 11 is installed at the copper sleeve opening 3, the air nozzle 13 is tightened on the surface of the external threaded sleeve 12, and the air source is connected to the air nozzle 13 to deliver gas into the injector copper sleeve 1. By observing whether water bubbles emerge in the water, it can be determined whether the injector copper sleeve 1 is leaking or damaged.

[0029] Working principle: When using the injector copper sleeve 1, the bolt washer 9 is placed on the surface of the pin bolt 8, and then the pin bolt 8 is installed on the surface of the first support plate 4, so that the bolt washer 9 abuts against the surface of the first support plate 4. Then, the first support plate 4 is installed on the front end of the injector copper sleeve 1, so that the pin bolt 8 is inserted into the positioning groove 2, until the first support plate 4 is tightly against the surface of the injector copper sleeve 1. Then, the second support plate 6 is installed on the rear end of the injector copper sleeve 1, so that the pin bolt 8 passes through the positioning groove 2 and emerges from the second slot 7. Tighten the four sets of nuts 10 sequentially onto the surfaces of the four sets of pin bolts 8, thereby fixing the first support plate 4 and the second support plate 6 onto the front and rear end surfaces of the injector copper sleeve 1. Then place the injector copper sleeve 1 in a basin of water, so that most of the injector copper sleeve 1 is submerged in water. Then install the copper sleeve cover 11 at the copper sleeve opening 3, tighten the air nozzle 13 onto the surface of the external thread sleeve 12, and then connect the air source to the air nozzle 13 to supply gas into the injector copper sleeve 1. By observing whether water bubbles emerge in the water, it can be determined whether the injector copper sleeve 1 is leaking or damaged.
