Additionally, intercoolers play a vital role in helping meet fuel economy standards by supplying the engine with adequate oxygen to maintain
air to fuel ratio ensuring proper combustion.
Turbochargers utilize the exhaust gases from the engine to compress the air and feed it back to the engine to create a better
air to fuel ratio. This generates a better combustion and provides a boost for the vehicle.
1976), the lower heating value of the blends ([LHV.sub.b]), the stoichiometric air to fuel ratio (AFR) (Heywood 1988), the Saponification Number (SN) and the IV (Kalayasiri et al.
The engine brake power, brake specific fuel consumption, brake thermal efficiency and air to fuel ratio were calculated.
While the equivalence air to fuel ratio and the brake thermal efficiency are lower by about of 5.2% and 1.8%, respectively (Table 4).
The air to fuel ratio is around 1.2 at no load condition and at peak load it is 1.5.
It can be seen that the air to fuel ratio is around 1.2 at no load condition and at the peak load it is maintained at around 1.5.
Charge air temperatures and volume, together with
air to fuel ratio and compression ratio, are constantly monitored.
By reducing the throat and the diameter of the air entry region, the combustion volume may be made smaller thus causing the
air to fuel ratio to tend towards the stoichiometric ratio and the temperature of the combustion zone to rise.
