High-performance piston engine, in particular Internal combustion engine

The invention relates to a high-performance piston machine, in particular an internal combustion engine

In such a machine, the engine block "that of cylinder b" generally forms "w". Cylinders and crankcase consists of a solid frame in which the crankshaft is mounted and on which the cylinder head is fastened. The internal pressure in the cylinder exerts a force on the cylinder head as well as on the crankshaft via the piston and connecting rod, which puts the !! © gate block under tension. Is still a significant thermal load in internal combustion engines to this mechanical stress.

Because of this heavy load, the engine blocks in internal combustion engines are mostly made of gray cast iron, cast steel or welded steel cast.For simple and quick production and to save on weight, however, we particularly endeavor to manufacture the engine blocks from borrowed metal cast iron in the case of propulsion engines.

The weight saving compared to iron or steel constructions is in this case about 35 JtV on the other hand

the service life of the engine block can be doubled and the rigidity quintupled with the same weight> if it is made of light metal.

Because of the ease with which light metal can be machined, the machining costs are only a fraction of that Costs that are to be expended for the processing of Elsen and steel structures,

However, the aforementioned tortelles are faced with serious disadvantages in lightweight metal constructions.

So, above all, the tensile forces in an engine block are from Light metal cast difficult to control · light metals have only a low fatigue strength with alternating and increasing tensile stress and tend to Material fatigue. The course of the Kraftfluesee in one Complex shaped component such as an engine block can also difficult to determine. Se is therefore very difficult to make an exact calculation of strength «,

In particular with Fahrseug diesel engines with high specific power and high speed, there are frequent breaks in operation if the engine block © is made of light metal.

Another disadvantage of a light metal engine blooke lies in the difficulty in finding the thread for that

heavily loaded fastening screws for cylinder head and crankshaft bearings to be attached. Such threads can

easily ripen.

In Pig. Conventional type shown 1 is fixed to the cylinder head 2 on Kotorblock 1, inside which the piston 3, the connecting rod 4, and the crankshaft 5 are calibrated · in the engine block and the lower bearing shell 6 is attached dos crankshaft bearing ·

The pressure prevailing in the cylinder exerts a force on the cylinder head 2 and via the piston 3 ₉ connecting rod 4 and the crankshaft S on the lower bearing shell 6, which is illustrated by the solid arrows. The power flow closes via the Hotorblook 1 as shown by the dashed lines. As a result, the engine block 1 is subjected to tensile and bending stress »which is particularly unfavorable in the case of engine blocks made of light metal.

In Pig. 2, in contrast to the conventional design, the crankshaft 5 is supported in a bearing support made of steel, which consists of an upper part 7 and a lower part 6 and is connected directly to the cylinder head 2 by means of screws 8 ® Mofesfelook 1 hinduoh. The upper part 7 and the lower part 6 of the bearing stud are fastened to the engine block 1 by further screws.

In this type of construction, the force flow closes over the Screws 8, as shown in Fig. 2 by the dashed lines Lines is shown. The engine block is thus from Tensile and bending stress relieves and only needs still assume the compressive forces resulting from the preload the screws 8 originate.

It is also much cheaper to use the thread for the Fixing screws of the cylinder head in the steel existing bearing supports 6, 7 to be attached ale in the aua Light alloy existing engine block.

It is also a lot easier to get the permanent feed of the steel components, in particular the screws 8 in the doorway, than is the case with a light metal engine block the pail is.
