Hello!
yeah.....660CC alto...on CNG...
i have'nt yet seen 660cc alto on CNG.......Alto local PS assembled runs fine with 1000cc engine without taking anyload.......with A/C on CNG.....i am not confirmed about 660cc alto......it should be fine as engine was MPFI but be check it power output before letting it installed.....engine should be min above 48hps in order to get fine acceleration and torque range should be 75+Nm in order to get load free drive......
a/c to my info....its K6A 658cc engine outputs are......
PS Alto 1000cc(LOcal)
Displacement:- 970cc
Cylinder Layout:- In-line 4 Cyl
Max. Output (PS / rpm):- 55PS/5,500RPM
Max. Torque (kg-m / rpm):- 8.5kg-m/2,500RPM
Fuel System:- Carby Type
Alto Japanese 660CC
Displacement:- 658cc
Cylinder Layout:- In-line 3 Cyl
Max. Output (PS / rpm):- 54PS/6500RPM
Max. Torque (kg-m / rpm):- 6.2kg-m/4000RPM
Fuel System:- EPI(Electrically controlled Gasoline Injection)
So 660cc aceleration is almost same...difference comes in redline as it 6500Rpm Max barrier.......it lacks torque as it maytake some load with loaded car....on CNG....but it runs fine on normal drive......so i think it can run on CNG but have to get EFI kit installed with some expert ot they will ruin its EPI System which will become quiet difficult to control.....
Thanxxx
