摘要

The heat exchanger (HE) has a first stage and a second stage (E1, E2) which are seated and affixed in a connecting block seated and affixed to the engine (M). The first stage (E1) is provided with a fuel inlet nozzle and a fuel outlet nozzle which are connected to the supply of fuel to the engine (M), and the connecting block defines: a return conduit, communicating an outlet of a cooling water circuit of the engine (M) with a water inlet in the first stage (E1); an interconnecting conduit communicating a water outlet of the first stage (E1) with a water inlet of the second stage (E2); an outlet conduit communicating a water outlet of the second stage (E2) with an inlet of a water radiator having an outlet; and two oil conduits, communicating a lubricant oil circuit of the engine (M) with the second stage (E2).
