Hybrid Diesels

[SwamiSalami]

I know many of us fantasize about owning one, but has anyone done a swap to see this through?

Any relevant information is greatly appreciated.

Peugeot did the first OEM available unit.

As far as someone doing a homemade unit, I have a feeling it's been done, just have to dig it up.

Isn't it ridiculous that it had to be a "crossover"? Why couldn't they make a golf or a fiat or something? They always get it wrong.

I think the implications have been discussed in another thread concerning this particular car, but I'll put a link to a homemade hybrid that can be dieselized.

This was in one the other forum sections.

Electric Car Conversion: The Amazing 75-MPG Hybrid Car

I'm noodling this myself, using a small, low power electric motor, mounted between the diesel engine and transmission.

The idea is to disable idling on the injection pump, and run a controller on a micro switch at the fuel pedal, so that the first inch of pedal travel would activate the electric motor at full power, which would start the car moving. At the top speed of the e motor, engage a clutch between the e motor and banger, effectively "bump starting" the diesel.

The setup would allow one to use either motor. Haven't worked out charging or the like, or any type of adopted deactivation of the e motor circuit, etc.

I'm thinking some sensor to determine if the banger is running could cut the circuit to the e motor drive side, and a circuit to determine state of charge and throttle position could be used to engage regenerative engine braking.

Most gov't subsidizing schemes in the EU are based on CO2 output.
Making more cars with lower CO2 output and have them subsidized by the gov't = more profit.

Fiat especially is playing that game to its advantage.
The 500 models that get our 15% gov't bonus are prized higher accordingly ...

That happened alot with cash for clunkers here... Dealers would keep the incentive via some tricky salesmanship.

Ya know, with that cheap killer controller, I can see a plug in / diesel hybrid being built. Maybe Ecomodder will do what the OEMs refuse to do.

But CO2 output = mpg, no?

On my hybrid idea: I start the engine with the clutch engaged at times, in first gear. The starter has a life time warranty, so I'm not worried about damaging it.

Point is, the starter had no trouble starting my 2500lb (car, me, crap inside, full fuel tank, etc) moving at all. Within one full crank, the pedal is functional, and I can let off the key and start accelerating.

Because this, I believe a 3-5hp motor would actually be overkill for my intended application, but it could also work as a failsafe device, I.e. if the banger don't bang anymore, it could stol get you somewhere off the road, or home, within reason.

5hp is enough to get a small car going pretty quick, too... I could see something like this used for in town trips with a plug in option.
