    Fiat has already entered the market with, may be the first automobile company who had introduced the small liter turbo petrol engines. Ford and VW which already have their turbo engines in stock and we can expect it at any time in coming years. 1.4 TSI is already there in Jetta. Now the discussion is on whether the Japanese auto giants Honda and Toyota can face the heat with their conventional bigger engines (non turbo). Are there any developments in that direction from auto giants. In india where petrol prices are already touching the roofs can they simply survive with bigger capacity engines? Right now from their failure in marketing their products the competition from Fiat is not there. But with the new policies from Fiat if they able to overcome the current problems Fiat will definitely urge the auto giants for moving towards turbo engines. Especially with their multiair engines. This is a discussion and let us see how our fellow members view on it.

    Very valid Sun. I think in a country like India where the petrol price is pretty high, a revolutionary engine like Multi air would be much welcomed by the manufacturers. In India manufacturers are doubtful whether to invest on Diesel technology or petrol technology as no one is sure whether Govt. will take off the subsidy on Diesel one fine morning which would be a disaster for Diesel market or there won't be a change in diesel price which would be not that good for petrol engines. So when smaller engines can bring out more power & mileage, manufacturers would definitely have to move to such options. Survival of the fittest. Hope multiair becomes our national petrol engine like our MJDs ;)

    How efficient is direct injection engines compared to MPI engines. Is it more efficient?

    - - - Merged Post - - -

    It has the power to become more popular than MJD if come with smaller capacity unit with a turbo.

    What we need is small unit engines for our daily commuting. Japanese cars with their low weights will have more advantage in terms of power to weight ratio.
  5. MPI is at least 20 year older technology DI in petrol ins new technology,new Sonata or Elanatra uses this technology.
    In layman terms MPI feeds air-fuel mix into cylinders DI will inject fuel alone with high pressure and depend on natural aspiration in low RPM to draw the air and forced induction using turbo as the RPM's climbs up. some what similar to what is used in CRDI diesel engines.

    The trend of small capacity Turbo petrol engine is catching up very fast in Europe, wherein VW and Renault had their small turbocharged Petrol engines. While, Renault has its TCE90 Motor, which is a 3 cylinder 900 cc engine whereas Volkswagen also displayed its 1.0L 3 cylinder turbocharged motor during the Sao Paulo Motor Show at Brazil, which was displayed at its Compact SUV Taigun. Ford too displayed its silent 1.0L EcoBoost engine which will deliver 120 bhp of power and will be equipped firstly in its upcoming Compact SUV for India and Chinese market. The Ford EcoSport will be launched in India in January 2013 and will followed by Chinese market. The compact SUV has already been launched in Brazil and Argentina.

    The South Koreans and Japanese have however been very quiet on development of small turbocharged motor, but recently South Korean manufacturer, Hyundai too displayed its small turbocharged 1.0L Petrol motor which will deliver 105 bhp of power and 137 N-m of torque.

    Hyundai also showcased a 1.1 litre diesel engine based on the U2 family (used on the Hyundai i20 in the UK) and a 2.0 litre R series diesel. The 1.1 litre diesel is important for India as it’ll be powering the next gen Hyundai i10 which had already started its testing phase in India.

  7. Japanese can come up with brilliant engine in short time as history proves it.I don't think it will take them a big time to plonk a turbo to 1.2 ltr engine and just take out 1 cylinder? They have mastered making small capacity petrol engines already.

    Another promising technology is homogeneous charge compression ignition (HCCI) which was in news years back and didn't get succeeded in coming out as successful. Now Bosh is going to work with a partial funding support from US Energy department in HCCI. They may be eying on a petrol counter part of CRDI for revenue. Bosch Hard At Work On Sparkless Ignition HCCI Engine

    If I am correct Ford Ecosport comes with DI turbo.

    Very true. City manages a 118BHP with their 1.5 Unit without a turbo. They are extremely smart.

    HCCI combustion is supposed to cut fuel consumption by 14 % and improve on emissions, using Bio-fuels this should cut short by 30%

    Not necessary.Japanese cars are very light.City goes gaga after 140kmph.Wobbles like hell, feels unstable.

    1497cc churns out 118bhp
    1368cc without turbo churns out 90ps

    Linea is clearly short of 129cc.If the cubic capacity is increased im sure it will beat the city hands down!

    Whos the winner??

    With even after so much weight the Linea manages 75bhp on wheels.Hats off!! I feel thats called technology and being smart with safety too :D
