Fuel flow path is formed with lower oil guide groove 5；The position of all oil groove partition boards in the axial direction is located at fuel inlet 10 and fuel outlet 11
Between.Fuel inlet 10 is connected with lower 5 right end of oil guide groove, and fuel outlet 11 is connected with lower 5 left end of oil guide groove.
In order to buffer the fuel pressure for entering oil guide groove, it is further additionally arranged surge-chamber, is fired in 2 outer wall face of heats
The import surge-chamber 8 of annular is provided at the position of oil inlet 10 around exhaust steam passage, is given up at the position of face fuel outlet 11
Gas channel is provided with the outlet surge-chamber 9 of annular.8 bottom of annular entrance surge-chamber is connected with lower 5 right end of oil guide groove, annular
Outlet 9 bottom of surge-chamber is connected with lower 5 left end of oil guide groove.
Since the thermal conductivity of fuel oil is very low, about 1/4000 or so of red copper class thermal conducting material, fuel oil is repeatedly turned back
The turbulence level of fuel flow can be increased, therefore be provided with kicker baffle 6 among lower oil guide groove 7, by kicker baffle 6 by lower Oil Guide
Slot 7 divides left and right two parts mutually to completely cut off.Kicker baffle 6 can be arranged 1-2, to shorten heat transfer distance, improve heating
Efficiency.Discharge capacity is in 1.5 liters of engines below, and kicker baffle 6 can be arranged 1, and discharge capacity is led in 1.5 liters or more of engine
