ABSTRACT:
An internal combustion engine comprises an iron block 2 and an aluminium head 3 held together by bolts 6. The bolts 6 extend through oil drainage passages 8 in the head and through bores 9 in the block and engage with the block at a point substantially spaced from the head/block interface. The increased length of the bolts 6 allows them to stretch to accommodate the relatively large expansion of the head as the engine warms up. Good thermal contact is provided between the bolts and the water jacket of the engine so that the bolts warm up quickly.
