4L43 Hatz 4L43 Specifications & Technical Data (2015—2018)

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.

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 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 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.

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.
