Abstract
A particularly reasonably priced cylinder liner (1) for combustion engines, especially for one-cylinder diesel engines with a cylinder (2) cast on the crankcase, is produced from steel by deep drawing or deformation by compression and inserted with a tight sliding fit into the cylinder bore (12).
Claims23
A combustion engine with one or several cylinders (2), which are lined with cylinder liners (1) characterized in that the cylinder liner (1) is inserted with tight sliding fit into the assigned cylinder bore (12) with a tolerance, which ensures an annular gap (9) between the liner (1) and the cylinder wall (7) with a gap width of 20 to 40.mu. at the operating temperatures, and in that the annular gap (9) is connected to cycling lubricating oil.
A combustion engine, comprising:
- at least one-cylinder bore having an inner-wall;
- at least one cylinder liner, a cylinder liner being positioned respectively in each said at least one cylinder bore, said liner having an inner running surface, said inner wall of said cylinder bore and said liner having a tight sliding fit between them, an annular gap with a width of 20.mu. to 40.mu. existing between said bore and said liner at engine operating temperatures;
- communication means providing an inlet to said annular gap for connection to a pressurized source of circulating lubricating oil,
- thereby said gap fills with said pressurized oil and is a flow path therefor.
