Engine Information of Honda Accord Plug in Hybrid

[matt]

The new Accord Hybrid will be based on Honda's Accord midsize sedan updated for the 2013 model year. Honda released details about the Accord Plug-in Hybrid, and is reserving further information on the Accord Hybrid until later. However, the differences are likely to be a smaller battery pack and less pure electric range for the Accord Hybrid as opposed to the Accord Plug-in Hybrid.

The new hybrid system in the Accord Plug-in Hybrid consists of a 2-liter Atkinson cycle four-cylinder engine under the hood making 137 horsepower, and a continuously variable transmission with an integrated 124-kilowatt electric motor. Rather than assist the engine, this motor will be the primary driver of the front wheels. Honda rates the total system output at 196 horsepower.

I think having a battery option is really handy if it can take the car upto 15 miles. I heard there is a portable charger which makes charging the battery really easy and it doesnt take much time to do so. Great features if you ask me.

Unlike a full-electric car such as the Ford Focus Electric, Nissan Leaf or Tesla S, there’s no range anxiety because of the Accord PHEV’s gasoline engine. Once that kicks in, you can go another 500 miles, Honda estimates, on a tank of fuel. Honda believes it will get more than 100 mpge while the 2013 Volt has eked up to 98 mpge (and 37 mpg under gasoline power). The mpge rating (miles per gallon of gasoline equivalent) equates driving using utility-company-supplied energy vs. driving the same vehicle with a combustion engine. Electricity is at least twice as efficient as gasoline, thus a car rated at 30-40 mpg will get an mpge around 90-100.

The new Accord Plug-in Hybrid’s powertrain combines a 2.0-liter 4-cylinder Atkinson-cycle gasoline engine that delivers a total of 137 HP at 6200 rpm with a two-motor hybrid drive system which includes a 124-kW electric motor powered by a 6.7-kWh Li-Ion battery pack. The car’s final output is taken up to an impressive 196 HP.

The Accord PHEV can drive in pure electric mode for 10 to 15 miles and delivers a total driving range of over 500 miles.

The new Accord PHEV will offer three driving modes: full-electric, "HV," and "HV Charge." In HV mode, the car acts as a conventional hybrid, blending motor power between gasoline and electric, while in HV Charge, the Accord PHEV blends gasoline and electric power while also augmenting the battery charge level.

I don't think weltonsee4 is correct.

There is no continuously variable transmission in the Accord plug-in... it's a clutch that may engage the motor to the electric drive (1:1) at speeds above 45 mph. Under 45 mph, and when accelerating, the electric motor is doing the additional work.

Since everyone seems to refer to the Accord Plug-in having a CVT (or an e-CVT), there needs to be more definition. Here, to get a bit more specific...

http://www.greencarreports.com/news/108 ... w-it-works

To quote:

"The 2014 Honda Accord Hybrid has no transmission.

To be more precise, there's nothing in a form we'd normally recognize as a transmission—no conventional automatic transmission, no automated dual-clutch system, no belt-and-pulley continuously variable transmission (CVT) either. There's no torque converter, either—not even a drive clutch to slip the engine from a standing start.

Enough about what the Accord Hybrid doesn't have; here's what it does have: In addition to a lean four-cylinder engine, there are twin electric motors (each purposed and configured differently), a compact 1.3-kWh battery pack, and an electronically controlled clutch pack. "

...

"Core to the system is that couplet of electric motors (we call it that because of how neatly they're packaged and nested together), of which one is always connected to the wheels. One of them drives the vehicle—the propulsion motor—while the other stays connected to the engine and functions primarily as a generator.
The gasoline engine in the 2014 Honda Accord Hybrid is a 2.0-liter in-line four, with i-VTEC intelligent valve timing and lift and an Atkinson-cycle. It makes a peak 141 horsepower and 122 pound-feet of torque, and it's not mechanically connected to the drive wheels under most driving conditions.

But in steady-speed highway cruising a multi-plate wet clutch and controller system connect it—essentially in a direct-drive configuration that's about equivalent to the top gear in conventional transmissions.

This unique arrangement essentially creates four different drive modes: Electric Vehicle (EV). Hybrid Vehicle (HV), Engine mode, and Regeneration mode."

So, no. No CVT.

To over-simplify, what you described is what Honda calls an e-CVT.

Please see:

Electronic Continuously Variable Transmission (E-CVT)
Gear Ratio: 2.450, Final Drive: 3.421

Not arguing with you at all... I read that too, and all of the incorrect press that the Accord Plug-in has a CVT!

That being said, the e-CVT is not a transmission, in the true definition of a mechanical CVT. And by suggesting that the Accord Plug-in has a CVT, it kind of mis-leads folks from the truly awesome tech that it does have!

So, shame on Honda for saying "e-CVT". What Honda is labeling as "e-CVT" is, in fact, just a set of modes for its motor/generator + engine & wet clutch system. I personally see the Honda system as superior to the e-CVT system such as the Hybrid Synergy Drive (HSD) in Toyota products, because it's simpler.

"An HSD transaxle contains a planetary gear set that adjusts and blends the amount of torque from the engine and motor(s) as it’s needed by the front wheels. It is a sophisticated and complicated combination of gearing, electrical motor-generators, and computer-controlled electronic controls."

As I mentioned in the post above, the Honda system does not have the mechanical transmission that the HSD "e-CVT" does. It just clutches the motor in when the conditions are right. The gear ratio you mention is FIXED. MUCH simpler.

So, again, not arguing, but there IS a difference, and "CVT" is not right. E-CVT is right, but... not really the whole story...

Yeah, I think they just made e-CVT a marketing name for something completely different than conventional CVTs.
