Presentation
The charge air cooler (CAC) reduces the temperature
of the intake air. This provides the cylinders with
greater volumes of air. This makes a high power out-
put possible while keeping the combustion and ex-
haust gas temperatures to appropriate levels. In addi-
tion, the emission of nitrous oxides is reduced.
The engines are equipped with an electrical starter
element. This facilitates starting and reduces exhaust
emissions in cold weather conditions. Does not apply
for engines 520/720 (COM1).
The instruction book covers industrial and generator
set engines from 4 to 16 liter swept volume.
The engines are four-cycle, 6-cylinder in-line diesel
engines with direct diesel injection (420/520 are 4-
cylinder diesel engines). The engines have replace-
able wet cylinder liners (the 420 does not have liners
and the 620 has dry liners), and have turbochargers.
All engines have piston cooling.
The TAD engines have an air-cooled intercooler, as
distinct from the TWD engines, which have a water-
cooled intercooler.
