Hatz launch new 4H50TIC engine

Latest product specially designed to meet upcoming EU Stage V emissions regulation

HATZ, the German manufacturers of diesel engines, have launched their new 4H50TIC engine, which has been engineered to meet the upcoming EU Stage V emissions requirements as the industry prepares to meet stricter emissions regulation.

For the first time, all industrial diesel engines with a power output of less than 19kW will have to comply with EU Stage V. The emissions legislation – which is set to be mandatory from January 2019 – stipulates that the particulate mass limit cannot exceed 0.6g/kWh, with the emissions limits for nitrogen oxides and hydrocarbons at 7.5g/kWh.

The new 4H50TIC is a two-litre engine equipped with a turbocharged intercooler. With a total weight of just 173kg and a maximum power output of 55kW, Hatz say that this combination makes the 4H50TIC the most compact and lightweight engine in its class.

The Stage V-compliant engine features a shared high-pressure reservoir (common-rail technology) that supplies all the cylinders with fuel. With conventional diesel injection systems, the fuel pressure has to be generated individually for each injection.

With the common-rail system, however, pressure generation and injection are separate, meaning that fuel is constantly available at the required pressure for injection. The advantages of the common-rail system include: clean and efficient fuel injection; high engine power; and smooth running with reduced consumption and exhaust emissions.

Hatz are anticipating keen interest in the 4H50TIC from the construction equipment sector as future compliance with EU Stage V looms. The 4H50TIC engine has been designed to suit many applications, including powering hydraulic power packs, screeners, power generation and pumping.
