This is truly interesting. The CK2610 Engine (3A165) has been in production since 2006. Been a great engine for the KIOTI Brand, and uses all the same technology that everyone loved for years. EPA Tier IV was implemented on Off Road vehicles in 2014, forcing the engine manufacturers to develop the Common Rail DI Engines. For years, we had people begging us for anything that still had the Tier III engine with the Mechanical Indirect Injection Engine. Now that the Tier IV technology has made it's way through the market, it appears from the discussion here that Tier IV stuff might not be all that bad???
You can please some of the people some of the time, but.......
From our experience here, they have both proven themselves to be good reliable engines...
I知 pretty sure That either AVL in Plymouth or FEV in Auburn Hills did she design and emission development for Kioti in the early to mid 2000 time frame, probably AVL, but I can稚 remember for sure.
I know that their engineers were spending a lot of time in Korea around that timeframe.
I don稚 know much about Kioti痴 engine history, but the basic layout and design attention for NVH attenuation , ie crankcase structure, etc looks pretty modern on my 4010. It would be typical of a manufacturer with a heavy investment in an engine transfer line to design a new, emission compliant engine that salvages as much existing tooling as possible, ie bore spacing, camshaft location, ets.
Itç—´ a pretty big job to upgrade an IDI engine, though, as firing pressures on a DI, especially a turbo DI, are much higher, requiring upgrades to the entire structure and rotating mechanism.
If indeed the 2510 engine is an IDI ( Kioti doesn稚 speak to that in their brochures, but the short oil drain intervals certainly point that way), I wonder at which point maintaining a separate IDI configuration becomes unsustainable.
Fuel system costs for example are volume sensitive, and the entire developed world, with a few exceptions, has moved to common rail.
As to TierIII /Tier IV fears dissipating with time, nobody wanted automatic transmissions, power steering, or power brakes when I was a kid. Mi remember the debates. Later it was electronic ignitions and catalytic converters. All those are commonplace and accepted by all but the fringe now.
Not at first, though.
