4th gen 2.0EB + PowerSplit eCVT transmission

[jacytbe]

Anyone have any information about the 4th gen 2.0EB used in the 24 nautilus hybrid? I'm guessing if its used with the hybrid only then the non hybrid gets the 3rd gen.

I can’t find anything official or unofficial yet.  Common speculation is its running some variation of an Atkinson cycle for better mpg.

Is there an interpreter available to put this chart into English?

I Suspect the Chinese market doesn't get the same powertrain as the US market. According to that sheet the combined HP of the hybrid is 270 (207 KW). That is with a 140KW electric motor....

That makes no sense-Car and driver is reporting 310HP with the hybrid (or 231 KW) for the US version and a 140KW electric motor (C&D is reporting 100KW for the US) is 187HP. the Non hybrid is supposed to make 250HP or 186 KW.

Yes the US spec sheet doesn't match the Chinese at all.  According to the numbers on the spec sheet they have a total output of 277hp vs 310 in the US. They claim a 140KW electric motor is used so that leaves just about 90hp for the gas engine vs 176 for the US gas engine. Honestly I wouldn't be surprised if this is true.

Just an FYI, you can't add the EM power to the ICE power to get total system power.  The EM produces its torque and power and the low end of the RPM band.  They phase the power output of the EM to decline as the ICE hits its peak power.  EM's are constant torque until they hit there maximum power output, then can either hold that power or start to decline as RPM is increased.  Most motor controllers only allow maximum power for a short band until the total power is reduced to preserve the motor health.  Also depends on the maximum battery output and how long the battery can sustain that power output.

For torque I considered that but for horsepower it does make sense seeing how peak ICE HP can develop higher in RPM than the motor generator might assist. Those combined numbers might be any combination of assist from the drive motors.
