<p>In order to enhance fuel integrity, the fuel injectors (18) together with the associated fuel feed and return passages (22) and (24) are formed in a single block (10) which also includes the air feed passages (16) to the engine cylinders. The incorporation of all these elements into a single block means that the block can be pre-assembled and tested for fuel tightness before being built into an engine.</p> |
