4L42C Hatz 4L42C Specifications & Technical Data (2017—2026)

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.

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.

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.

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.

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.
