Manufacturing of Crankcases, Manufacturing of Housing-like Engine Parts

We produce crankcases, housing-like engine parts for V-engines and in-line engines.

The Anton Mauss GmbH in Cologne specializes in the manufacturing of crankcases and housing-like engine parts.
We produce crankcases and housing-like engine parts in the range of 1 kg to 2500 kg.

We produce crankcases using modern CNC controlled machining centers and turning lathes. Crankcases are exposed to extremely high stress. In order to hold out against this extreme load, a true to dimension work is required when manufacturing crankcases.

What is a Crankcase?

The crankcase, also referred to as engine or motor block is just the trunk of the engine without its cylinder head.
Therein, the crankshaft in its bearing shell, as well as the connecting rod with its piston, are constantly revolving.
The crankcase forms a central part of the engine, to which various components are connected. That also goes for all pipes and hoses, passing through this constructional element. The high strain results from the piston stroke itself, and the combustion process as well as the elevated temperatures of the oil (>100°C), circulating inside the casing.

A crankcase can be classified into three types of crankcases, depending on their cylinder arrangement:
In this regard, one differentiates between in-line engines, flat engines and a so-called V-engines.
in-line engines, the cylinder’s array in a row, while flat engines cylinders’ mount opposite to each other and in V-engines, two rows form a V-shape.

The number of cylinders varies from one to eight cylinders in in-line engines, in flat engines from two to eight cylinders and in the V-engines from two to sixteen cylinders and over.
The crankcases in four-stroke engines usually close outward with oil pans.

Function of the Crankcases

Functions of the crankcases are among other things:

  • absorbing the forces, like the gas and inert forces, resulting from the combustion process and the oscillatory piston stroke;
  • cooling of the engine
  • in some cases, attachment point of cylinder liners
  • gas-exchange cycle, scavenging pump, initial compression of unburnt gas with two-stroke engines.
