Re: Turbocharging and Fuel direct injection in Petrol Engines Yes, its correct that Mitsubishi has more patents for GDI, it was way ahead than what Europeans were, but unfortunately it was too early. And now Mitsubishi is in not so healthy form.
Regarding GDI there are two view of mine:
1) I agree with GTO that it has more to do with costs. But over and above costs which would increase, another reason is maintenance. If at all there is higher maintenance, it wont go down well with car owners. Cost remains a tough constraint. An Alto with GDI + turbo would be a great deal, but the FE ( due to performance available ) might decrease, more maintenance, and over and above that expensive spares. This wont be digestible to lower spectrum of market.
2) Ignorance. Its not that GDI + Turbo is not available to Toyota or Suzuki. Suzuki is selling Turbo 660cc engines since long. Given the Suzuki's expertise in small car tech, they can have a small GDI+turbo combo, but what about parameters like fuel quality, etc. Still people go to local mechanics who are not well versed with complex mechanics of modern cars in many cases. What would happen then ?
The fuel quality, maintenance cost are two major hurdles IMO. Quote:

Agreed, but Japanese have proven to be quite competitive, I mean they are not stagnant. A 1.2 without turbo in Europe can produce around 90 bhp., which means that specific outputs have gone up. Without turbo the Japs have managed to meet the tough emission norms in EU. So, IMO, they are working in a positive direction.
But as far innovation is concerned, IIRC, Honda openly admitted that they were left behind in turbo petrol tech. Suzuki and Toyota via Daihatsu can bring this technology to India in small cars IMO, but it will take time. |
