Having spent a day stuffing around with the Victa recently, I wondered why 2 strokes aren't suitable for modern cars, although there used to be a little Suzuki or Daihatsu, maybe both, some years back that I think were 2 strokes. Why aren't they used?
My Dad used to have a Suzuki 4WD with the awesome bigblock 540cc 2-stroke! Top speed was only about 110km/h downhill with a tailwind. It wasn't a bad car, underpowered but went everywhere being the lightweight small thing it was. Use to use nearly as much oil as an LS1 though...
COuldn't tell you why you don't see 2-Strokes in cars these days, maybe they aren't torquey enough?
You know, somebody actually complimented me on my driving today. They left a little note on the windscreen. It said, 'Parking Fine.'So that was nice.
Orbital Engine Corporation still exists, though Ralph Sarich hasn't had any involvement for years. They no longer use an orbital engine as such but apply their injection technology (Orbital combustion process) to a piston engine.
2 Stroke engines in a car wouldn't be pratical it has less power is more noisier and gives out more pollution.
Besides a lot of people would have a hard time figuring out the Fuel/oil ratio unless the fuel companies have it premixed.
Less power? Don't think so, a two stroke will always make more power than an equivalent 4 stroke cause it has twice as many power strokes. Dont forget that the new 4 stroke GP bikes need 990cc to compete with 500cc 2strokes. The problem with twostrokes is that while they can be developed to give good torque, this occurs at the expense of power. When tuned to give good power, bottom end torque is non existent and the power is developed in a savage on-off rush. Also, they chew petrol and are filthy in terms of emsissions. Premix should be a problem, most two stroke bikes since the early 70s have a seperate oil resovoir which mixes itself with the incomming charge.
