AGCO Sisu Power (ASP) has
developed new medium-duty three-and four-cylinder engines, the ECO
engine range, with outputs less than
134 hp. The target of the project
has been to develop lower-cost tractor engines, which will replace current externally sourced engines in
AGCO’s various small tractors. The
engines will be available for all emissions requirements from unregulated
to Tier 4 interim, and the fuel injection system will be either mechanical
or common rail based on requested
The manufacturing locations for the
new engine range will be Brazil and
China, where AGCO is currently building
a new factory for engines and tractors.
The target cost reduction will be achieved
by new design and by utilizing best-cost
country sourcing. The start of the serial
production will be mid-2012.
EPA Tier 4 interim approval was granted in mid-December 2010 for AGCO
Sisu Power engines over 174 hp. The corresponding European Union (EU)
Stage 3b approval was granted earlier in 2010. The EPA approval was
granted for nonroad engines utilizing selective catalytic reduction (SCR)
AGCO Sisu Power is currently testing various options to meet Tier 4 final,
which in any case requires further developed SCR with high NOx conversion
efficiency. Most probably, cooled EGR is needed for NOx reduction, but ASP’s
target is to keep the share of exhaust to be circulated as low as possible in order
not to increase the need of cooling capacity too much.
ASP said it will avoid diesel particulate filters (DPFs) for its Tier 4 final engines.
The regeneration process and the risk of the DPF blocking can thus be avoided,
the company said. The narrow exhaust temperature window in NRTC-cycle
requires thermal management and for that reason intake air restriction has to be
arranged by using throttling, ASP said.

Completely redesigned for 2011, the new GX120, the
GX160 and the GX200 are single-cylinder, horizontal-shaft
engines with outputs from 3. 5 to 5. 5 hp that replace the
existing GX120, GX160 and GX200 models.
Honda said the new engines are applicable for an array of
commercial turf applications and equipment including gen-
