TK 482, TK 486 and TK 486V
TK 482 and TK 486, direct injection diesel engines use an in-line injection pump. TK 486V injection diesel engines use an
mono-plunger and distributor injection pump. The mono-plunger and distributor injection pump uses a higher injection pressure
than the in-line injection pump. The higher injection pressure atomizes the fuel more efficiently, which reduces the emissions.
The injection pump camshaft is driven at one end by the engine timing gears. The cam lobes actuate the plungers, forcing fuel
through the injection nozzles. A governor assembly is connected to the other end of the injection pump camshaft. The governor
meters the amount of fuel delivered to the injection nozzles by controlling the position of the plungers.
