Abstract
In an internal combustion engine, especially a multi-cylinder four-stroke diesel engine with split cast crankcase comprising two half-shells (1a, 1b) clamped together by fastening studs, with the joint plane running in the direction of the crankshaft and cylinder axis, there are disposed, in recesses provided therefor in the half shells (1a, 1b), separate cylinder sleeves (2), each closed at its top end by a separate cylinder cover (10) with a circumferential rim. These cylinder covers (10) are completely clamped sealingly between the crankcase half shells (1a, 1b). A method for making such an internal combustion engine is also described.
Claims8
A multi-cylinder internal combustion engine, especially as a four-stroke diesel engine, with split cast crankcase comprising two half-shells (1a, 1b) clamped together by fastening studs (22, 24), with the joint plane running in the direction of the crankshaft and cylinder axis, characterized in that
- separate cylinder sleeves (2) are disposed in recesses provided in the half shells (1a, 1b), and in that the recesses are closed at their top ends by separate cylinder covers (10), each provided with a circumferential rim (14) with which they are clamped sealingly at least partly between the crankcase half shells (1a, 1b).
