Today we woke up with an idea: to talk about the comparison between 1.5 and 1.9 liters diesel engines. To be honest, we report the comparison from Diesel International’s May issue. An summary that starts with the following: In our comparison between 9 and 11 litres, Isuzu earned a special mention though being excluded from the ranking list due to missing Stage V data, and now another Japanese will be impacted by the same regulatory restrictions.

Comparison between 1.5 and 1.9 liters. Mitsubishi

Indeed, this comparison’s average is around 30 kilowatts, so we’re above 19 and the weight of Stage V is felt – it definitely is. So once again for reasons of compliance with emission standards, a Japanese contestant – namely Mitsubishi, currently a rarefied presence in mobile applications tradeshows – was supposed to be listed “in brackets” since we could not find info related to Stage V.  Instead, we made up our mind to make our matrix as flexible as possible and include their S4L2. A due tribute to the Japanese engineering heritage, which dominates this segment. The 4 cylinder diesel engine by Mitsubishi is available in both an aspirated version with 28.8 kW at 3000 rpm, and a turbocharged one, 36.8 kW at 3000 rpm, and 125 Nm at 2000 rpm. It’s the only turbo in the SL series, cylinder displacement is 440 cc.  

Hatz rules

It’s Hatz that breaks the Japanese soliloquy. Whatever the segment between 1 and 2.5 litres, their series H hits the spot on Diesel index. Their 4-cylinder was ruled out by a handful of cubic centimetres, since we decided to keep the comparison below 1.9 L. No harm done for Ruhstorf anyway. Hatz’s modular  – hence 1.5 L – 3-cylinder was unveiled at Bauma in 2016.



Powertrain 5/2021 introduced by the editorial staff

As usual, the editorial staff released a video to introduce Powertrain 5/2021, the fourth of six issues of the magazine to be released in the current year. The e-magazine is available at this link. In the editorial, we wonder if the EU will become a hub for hydrogen and biomethane. Did you know that...

The Brokk 900 is available both with a 71-kilowatt ABB electric motor and in the diesel version (with Kohler or Kubota engines), with emissions standards up to Tier 4 Final for the American market or Stage V for the European market. The power supplied is in any case around 55 kilowatts.
