MEE Dubai 2019: some important absences and gas engines and Stage V as the main themes

MEE Dubai (Middle East Electricity) is still one of if not the most important event for power generation, yet this year it suffered the absence of some important names in the industry. We are talking about names such as Mtu, Caterpillar and Himoinsa and also Indian builders, such as Mahindra Powerol and Kirloskar. There were also some OEMs missing like Bruno Generators to make another European example.


Nonetheless, the MEE Dubai saw the presence of important protagonists under the two main trajectories of the event: the promotion of gas and the top segmentation of displacements.

The first signal came from Cummins, with a 78-liter engine, capable of delivering up to 2 megawatts and a thermal efficiency of 47.1 percent. The name is HSK78G, a supercharged 12-cylinder engine, with a compression ratio of 13:1 and an electrical efficiency of 44.2% for 50Hz and 43.5% for the 60Hz models.

Present at MEE Dubai: Baudouin and Perkins

Baudouin was present, having played a leading role in the sector over a two-year period. The big bang of the 16M55 research and development dates back to four years ago, a 16-cylinder engine with a 5.5-liter barrel that for 50 Hz applications is able to deliver from 3,000 to 3,750 kVA. Among the new faces, also the 4M11, with variable revolutions.

At Perkins booth the 1706A improved its power density by over 22 percent. A result due to an overall recalibration of suction, combustion, piston bowl geometry and injection. The starting point is good: the 9.3 liters is in fact best in class in its category for mobile applications, according to the Diesel Index. The real news, however, concern the officialization of the Stage V approval for the entire EP (Electric Power) range. Jaz Gill, Vice President of global sales, marketing, service and parts, said: «We have made a significant investment across our Stage V engine range to provide power dense and efficient engines, ensuring low consumption of diesel exhaust fluid».

Scania and Doosan

Scania is also focusing on gas, continuing on the “road” of the truck sector, where it shares the scene of LNG with Iveco. The protagonist is the V8, presented as a world premiere for biogas engines, clearly weakened compared to its diesel parent, with a redesigned software mapping and a different compression ratio: from 364 to 455 kVA at 50 Hz in PRP and 360 in COP (respectively 409 – 477 kVA and 383 kVA at 60 Hz). The common denominator is the commitment to Stage V regulations.

Doosan was also present and unveiled the pioneers of electronically controlled G-drives. Bosch injection, DOC, DPF and SCR for the highly regulated emission versions, from October they will be available in two sizes. The DX12 is a 6-cylinder in-line engine, 11.1 liters, 414 kW at 1,500 rpm, 448 kW at 1,800 rpm, while the DX22 is a 21.9-liter 12-cylinder V-engine, with 875 kW at 1,500 rpm, 995 kW at 1,800 rpm. The compact engines of the G2 Stage V family (D18, D24 and D34) were also on display.

John Deere, FPT and Kohler

John Deere has exhibited, among others, the EWS, made in Saran, the 4.5-liter G-Drive complete with after-treatment system but without EGR, to promote a better thermal balance. It also brought along the whole Stage V family.

FPT came with the 55 kVA F34, which recovers the recirculation system, here named ecEGR, which had been banned from the NEF and Cursor series. The exhibition also included the ‘revival’ of the protagonists of the last two editions, the 600 kVA Cursor 16, the S8000 and the N67.

Recorded presence also for KDI engines at the Kohler SDMO booth.


FPT Industrial: let’s go, XC13

The XC13 surely sounds agnostic in FPT Industrial’s unofficial nomenclature; it comes, indeed, with a tripartite certification: Euro 6E (winking an eye at the upcoming Euro 7), methane gas and also biofuel, with a link to hydrogen. Andrea Abbà, FPT’s product marketing manager, told us about dialogui...
