Hello Marco, greetings, I am also from Chile (Rio Bueno) it is very likely that this machine comes with a motorization similar to that of the Mitsubishi Colt with a 1.3 engine of 12valv. The 4G13 mitsu but with a lower piston diameter to leave that 1 liter engine. This data is only because of mechanical intuition, almost all Chinese engines are clones of large house engines; Yueyin Motoriza with Sofin (Iveco) etc.
If you have the self -tank reference with that engine if you want, it is the most similar, the Chinese may have invented the double cam but nothing more,
