From the obtained results and various comparisons, the following conclusions can be drawn: 1)
In the case of using LPG in SI engines, the burning rate of fuel is increased, and thus, the combustion duration
is decreased. As a consequence of this, the cylinder pr
essures and temperatures predicted for LPG are higher
than those obtained for gasoline. This may cause some damages on engine structural elements.
2)
LPG reduces the engine volumetric effi
ciency and, thus, engine effective
power. Furthermore, the decrease in
volumetric efficiency also reduces th
e engine effective efficiency and co
nsequently increases specific fuel
consumption.
3)
LPG decreases the mole fractions of CO
and NO included in the exhaust gases.
4)
In summary, LPG has negative effects on engine perfor
mance, fuel economy and en
gine structural elements
when it is used at the same fuel–air equivalence ratios
as gasoline, however, it has positive effects on obnoxious
exhaust emissions such as CO and NO.
