Systems manual or description

[Sailover]

I bought my Fusion completely on impulse, knowing nothing about them. It looked good, is in great condition and drove well. The more I drive it, the more I like it..I would like to have a detailed systems description with diagrams and explanations to learn more about it. Does anyone have access to such? Thank you.

Owner's manual?

 

I have a 2010 Fusion as well, so welcome to the club! In some ways, I like it better than our 2013!

What I want to find is a technical description of the system such as where components are, how they operate and the parameters. Ford has teased me with the information available on the panel and now I want to know more.

Here's some info: https://www.greenhybrid.com/forums/f13/introduction-ford-hybrids-20777/

 

I assume you have the Owners Guide and Hybrid Quick Reference guide. If not they can be obtained on-line. A block diagram of the FFH would look the same as a Prius but the architecture is different. Prius transmission motors are on the same axis but the larger Ford transmission has the larger traction motor MG2 mounted parallel to the planetary gear. The Ford is an eCVT that uses a planetary gear train instead of variable cones and belts. eCVTs have hardly anything to wear. They are just gears meshing with gears turning in bearings. No valves, solenoids, bands, torque converters. The power transfer and mixing between the ICE and motors is controlled electronically by software that varies the torque on "MG1" which is connected to the "Sun Gear" of the planetary gear. The carriage for the "Planet Gears" is connected to the ICE and the "Ring" gear is connected to "MG2", the traction motor, and through a differential to the wheels. There are no clutches or shifts. MG1 can operate in either direction as a motor or a generator. It also starts the ICE. There is no alternator or separate starter. There is a DC to DC converter to charge the 12 vdc battery from the HVB. The 12 vdc battery does not start the ICE, the HVB does. The HVB is protected by software and relays from ever being completely discharged in which case it would probably be "toast".

 

Maintenance on a 2010 might be O2 sensors, dirty throttle body and noisy/failed electric vacuum pump.

Fantastic lolder, this is exactly what I am looking for. I will register with Greenhybrid. Thank you!

Lolder, a few questions. The power steering, air conditioning and alternator are all hv systems, so what does the ice drive belt do? Is there any way to inhibit ice start if I am just repositioning the car? The idle seems rough but smooths out when engaged, just normal at 200,000 miles? Thanks again.
