Hatz Diesel develops bolt-on DPF for L and M series engines

Hatz has revised its three and four cylinder L and M series air-cooled engine packages to comply with emissions regulations by including a cooled EGR system, DOC and DPF with active regeneration. The exhaust after-treatment package can be remote-mounted, said Hatz, and brings a 2dB(A) reduction in exhaust noise to the air-cooled engine.

Hatz’s Diesel’s 1D81 Hydro concept has been developed to offer a low noise level solution for applications using single-cylinder diesel engines. Still at prototype stage, the 667cc and 772cc capacity single-cylinder engine is a new variant of an existing Hatz engine design. As such, it uses common components from the Hatz range, but it differs with an all-new cylinder block and cylinder head design that includes a water jacket, allowing liquid cooling to be introduced.
