Fiat has decided that it will be building its new small SGE engine at its Bielsko Biala plant in southwest Poland. The SGE (Small Gasoline Engine) is Fiat’s smallest engine with only two cylinders and a 900cc displacement. It will be going into the upcoming Fiat Topolino and other small Fiat cars like the Fiat 500, Fiat Panda and possibly the Fiat Grande Punto as an economical baseline engine.
The engine will be equipped with Fiat’s Multiair electronic variable valve timing system and will have a few tune levels available ranging from a normally aspirated 65hp output to a turbocharged 110hp output. The engine design reduces the weight of a conventional 4-cylinder by 20% and installed volume by 25%.

900cc that can produce 110hp..interesting!
but output from most of superbike engines is greater (without force induction of coz) ..this is due to racing tech ehh?? anyone know?
one can’t compared car engine & superbike engine per se, even though the cc is almost similar. 1 thing for sure, superbike engine thrives on high rpm but the torque isn’t that outstanding. Typically road going car engine rev hardly exceed 5 figures rpm.
Good! the fuel consumption would be great in this. Small car small engine and big saving in fuel definitely
110 bhp …super light super supermini
suddenly the concept of a two cylinder econobox like the Tata Nano is not an isolated one. Foresight on Ratan Tata’s part perhaps?
Anyway is that an engine with a boxer layout? what seems weird is the engine is half the size but weight is only reduced by 20% and worst volume only 25%. That means the combusted volume of fuel, which has been reduced by half (from 4 cyl) effectively HAS to deal with more weight. Doesnt seem like a logical approach. There should have been more reductions in weight and space.
i have a feeling they are comparing to a 4 cylinder engine of equal displacement
test
WILL THIS BE ON THE FIAT 500 ARIA?
Wah…Macam motosikal.
Oh no, car companies are introducing lesser cylinders? that means more noise and vibration! I personally consider 4 cylinders low and anything lower is just brute and uncivilized.
Nah, I don’t like this.
This is an important and worthy engine development. Technology advance increases the power-per-cylinder year after year. Economy is crucial. Fuel costs will rise greatly as supplies run low and the two cylinder engine offers less fuel consumption and less total engine friction than an equal displacement four cylinder engine.. Acceptable ngine refinement can be had by using two sets of counter-rotating counterbalance shafts; one at engine speed and one at twice engine speed. Less complex balancing is available at slightly less refinement. Either approach will be coupled with elastic engine mounts. Computer controlled mounts are another option for higher-end vehicles. As engine sizes shrink, combustion chamber space for direct fuel injection, four valves, and a spark plug or two becomes very precious. Two cylinders give more space per cylinder for a given engine displacement and eases the engineering challenge. Durability is more a matter of materials, precision, and design than of how many cylinders are used. Fiat and Tata are going with parallel twins, but a V-twin is another very feasible approach, using counter-rotating counterweights at twice engine speed to quell the secondary imbalance forces. Not to be ignored is the important engine compartment space savings allowed by having only two cylinders to find room for.
