Exhaust gas recirculation (EGR)
For years already the Hatz 4L42C has been successfully fitted with a
robustly designed exhaust gas recirculation system for fulfillment of
the emission standards in Europe and the USA.
22
Wide power range, one engine platform
The L-series of the Hatz diesel engines is available as two-cylinder (2L41C) with
15 up to 24 kilowatts, three-cylinder (3L41C) with 23 up to 37 kilowatts and
four-cylinder (4L41C and 4L42C) with 30 up to 49 kilowatts. This saves both time
and money for the development and construction of entire machinery series.
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
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.
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 is fitted with an exhaust
gas recirculation. The engines fulfill the strict emission
standards of EU Stage IIIA as well as the regulations of
the US EPA Tier 4 interim. In the configuration below
19 kilowatts the Hatz 2L41C even fulfils the requirements of EU Stage V and US EPA Tier 4 final.
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 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.
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 automatically stopped to
prevent engine damage.
The Silent Pack
The innovative Hatz Silent Pack is still unrivaled today
by competitors. Radiated noise emission is reduced by
90 percent due to use of the engine capsule. This
means, 10 Silent Pack 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, Silent Pack engines – like
all other Hatz engines – can be used under virtually all
climatic conditions.
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 120 countries are
available quickly and dependably with advice and assistance as well as Hatz Genuine Spare Parts.

Power ratings
For the power ratings, refer to standard reference
conditions of ISO 3046-1 (IFN):
+25°C (77°F), 100 kPa, relative humidity 30%. The
specified power is reached during the running-in period,
and can be 5% less on delivery. Power reduction acc. to
ISO 3046-1. Standard values: More than 100 m above
sea level approx. 1% per 100 m. Above 25°C approx. 4%
per 10°C. The power taken from the alternator also has
to be added to the power calculation.
