The lowest compression ratio of a compression-ignition engine that allows a specific fuel to be ignited by compression ignition.
It wouldn't necessarily run better at all - it all depends on your ignition and timing setup and compression ratio.
You have an ignition Control Module that you can check that controls ignition timing Throttle Position Sensor that tells the computer where the throttle is so it can regulate and give the correct air fuel ratio.
It can refer to the fuel to air ratio, in the piston of an engine, prior to ignition.
23:1 compression ratio
The compression ratio is 8.5:1 supercharged motor and 9.4:1 for the non-supercharged motor.
For a Briggs and Stratton motor 3.5 motor used straight gas and oil in the crank-case, there is no ratio.
S.I Engine lower compression Ratio is 6 to 11
Mixing ratio should be 50:1
ratio of energy output to energy input.
my 43 cc scooter has a 1/25 ratio
