Environmental aspects
Hatz diesel engines in the L/M series are the only
exhaust-compliant, air-cooled engines available
in this power range. The Hatz 4L42C with exhaust
gas recirculation (EGR), the Hatz 3L43C as well as
the Hatz 4L43C are also fitted with an electronic
speed governor and removable diesel particulate
filter (DPF). Engines in the Hatz L43 series fulfil the
strict emission standards of EU regulation 97/68/
EC Stage IIIB as well as the regulations of the US
EPA Tier 4 final.
The SilentPack
The innovative Hatz SilentPack is still unrivaled today by
competitors. Radiated noise emission is reduced by
90 percent due to use of the engine capsule. This means,
10 SilentPack engines emit no more noise than a single
non-encapsulated engine. The capsule consists of sheet
metal with structure-borne sound insulation that is mount-
ed on the engine. All control and service points have easy
outside accessibility. Due to the cooling air circulation,
SilentPack engines – like all other Hatz engines – can be used
under virtually all climatic conditions.
Unique automatic engine protection
The integrated, intelligent, mechanical automatic
engine protection protects the engine. When a
cooling fan malfunctions, there is not enough oil, or
the inclination is too high, the engine is automati-
cally stopped to prevent engine damage.
Fuel consumption and cold start
L-series engines are among the most efficient in
the market. Fuel consumptions of 232 grams per
kilowatt hour testify to the optimized combus-
tion process. 6-hole VCO nozzles, as well as the
monoblock single stage pumps, and the optimized
combustion chamber geometry all make their
contribution to this. Without a pre glow system the
engines start reliably as low as -10 °C; with a pre
glow system and corresponding resources even
-32 °C is no problem.
Robust and durable design
Hatz engines are designed for an ex-
ceptionally long service life. The best
possible materials and components
coupled with uncompromising qual-
ity assurance contribute to the fact
that Hatz engines have been setting
the benchmark in the industry for
many years when it comes to robustness and service life.
And should, contrary to expectations, a spare part actually be
needed, more than 500 service partners in 120 countries are
available quickly and dependably with advice and assistance
as well as original spare parts.
Hatz L-series:
Economic, fail-safe, quiet
These are the qualities that characterize Hatz L-series engines. Their rugged
design gives them an extremely long service life. The crankcase and single cyl-
inders are made from indestructible gray cast iron, the power train and bearing
points are generously dimensioned giving them an extremely long service life.
This allows L-series engines to be operated in even remote areas or for appli-
cations without constant monitoring.
