Elring can supply gaskets of all types - metal layer, metal-elastomer and metal-soft material - individually matched to the requirements of each particular engine.
Cylinder-head gaskets (CHG) have a crucial role to play in the advancement of engine technology, particularly with respect to high-performance diesel engines and petrol engines with direct injection. Development work at ElringKlinger always focuses on the entire engine system. Around 45,000,000 cylinder-head gaskets are produced each year. Whatever the engine concept, we can provide the right sealing system accompanied by an engineering service to speed up the development process from the original idea to production standard.
Requirements for cylinder-head gaskets:
- Gas-tight, coolant-tight, oil-tight
- Ductile, no re-torque, low distortion
- Resistant to chemical influences (combustion gas, lubricant/coolant)
- Engine designs with optimised weight help to cut fuel consumption and emissions and result in higher diesel engine ignition pressures
- Reduction in component stiffness through the use of light metals and thinner casting walls
No – you can find all the necessary steps in our TSIs or our installation films in our library. The fundamental difference between metal/soft-material and multi-layer steel (MLS) gaskets lies in the required surface quality of the components. Both the roughness and the topography must be much more precise and finer. It is assumed that the required quality can only be achieved through machining.
The gasket variant comprising black coated steel sheet with an additional protective layer (shim) promises better results. The shim must be fitted between gasket and head. There are many steps to follow with this vehicle, as this is not a simple repair. You will find further information on this topic in the TSI.
There are manufacturers who allow reuse even with modern anti-fatigue bolts. In this case the rate of expansion must be measured, and modified tightening instructions may need to be adhered to. As the structure of a modern screw may also be changed by the expansion and the thread may be considerably elongated, we recommend always using new screws, for which our enclosed installation instructions are designed.
