AI Technical Summary
Technical Problem
Existing injector gripping devices are difficult to automate in internal combustion engines, and the bolted connections lack elasticity, leading to loss of sealing force and settlement, which affects the ease of assembly and maintenance.
Method used
The gripper device with a sleeve structure uses an expansion bolt connection between the sleeve and the gripper to increase the elasticity of the bolt connection. The tapered contact surface and stepped hole design prevent incorrect assembly, thereby improving assembly efficiency and sealing performance.
Benefits of technology
It improves the elasticity of bolted connections, reduces sealing force loss, enhances ease of assembly and maintenance, and ensures stable fixing and sealing of the injector.

Abstract
This invention relates to an internal combustion engine, particularly an internal combustion engine for motor vehicles, and especially a diesel engine, having at least one working cylinder and a cylinder head that seals the working cylinder. An injector for fuel injection is provided in the cylinder head for the working cylinder. A tensioning clamp is provided for the fuel injection injector, one end of which is supported on the other end. The tensioning clamp has at least two arms, which are configured such that the arms of the tensioning clamp act on the fuel injection injector and the fuel injection injector is pressed in a sealed manner against a seat or seal in the cylinder head with a defined force. The clamp bolt, implemented as a through bolt, has a bolt head shoulder and a corresponding thread in the cylinder head. The clamp bolt secures the tensioning clamp to the cylinder head. The arms of the tensioning clamp are configured such that they are supported on a support surface on the injector and on a support surface on the cylinder head.
