Control device for a diesel-operated internal-combustion engine and oil-heating system

A control system for a diesel internal combustion engine, comprising:

• a diesel fuel line for a diesel internal combustion engine;
• a cylindrical mixing chamber having an open end opening perpendicularly and vertically into said diesel fuel line and formed with a cylindrical wall extending to said open end;
• a cylindrical air-guiding body in said chamber, surrounded by said wall and having one end of said body turned toward said diesel fuel line and another end of said body turned away from said diesel fuel line, said body having a cylindrical wall between the ends of said body defining an annular air-flow gap with said cylindrical wall of said mixing chamber;
• an air supply line communicating with said chamber at an end thereof opposite said open end of said chamber and containing:
• a heater for dehumidifying air fed to said mixing chamber heating the air to a uniform temperature, and
• a limiter in said air supply line downstream of said heater and upstream of said mixing chamber for establishing a maximum air flow from said air supply line to said mixing chamber;
• a plunger on said other end of said body axially movable in said mixing chamber and controlling flow of said air between said walls to said diesel fuel line.
