LR3/Disco 3
The aluminium gravity die cast cylinder heads are unique to each cylinder bank. Eight deep-seated bolts, to reduce
distortion, secure each cylinder head to the cylinder block. The cylinder head bolts are located beneath the camshafts,
four under the inlet camshaft and four under the exhaust camshaft. Two hollow dowels align each cylinder head with the
cylinder block.
NOTE :
NOTE :
The cylinder head has four ports machined at each cylinder location, two exhaust ports and two inlet ports. One of the
inlet ports is helical and functions as a swirl port, the other is arranged laterally as a tangential port and functions as a
charge port.
The six fuel injection nozzles are centrally mounted; one above each cylinder and each is fixed to the cylinder head by
means of a clamp and two M6 x 35 bolts. For additional information, refer to
