Environmental aspects
Hatz diesel engines in the L/M series are the only
exhaust-compliant, air-cooled engines available
in this power range. The 4L42C with exhaust gas
recirculation (EGR), the 3L43C as well as the 4L43C
are also fitted with an electronic speed governor and
removable diesel particulate filter (DPF). Engines in
the 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 % 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 mounted 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 cool-
ing fan malfunctions, there is not enough oil, or the
inclination is too high, the engine is automatically
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 g/kWh testify
to the optimized combustion 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 exceptionally long
service life. The best
possible materials and
components coupled with
uncompromising quality
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 115 countries are available quickly and depend-
ably with advice and assistance as well as original
spare parts.
Hatz L-series:
Economic, fail-safe, quiet
These are the qualities that characterize L-series engines. Their rugged design
gives them an extremely long service life. The crankcase and single cylinders
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 applications
without constant monitoring.
