| Abstract: | This study presents effect of
engine performance, exhaust emissions and combustion characteristics of a
single cylinder
laboratory based four stroke cycle
direct injection (DI) diesel engine fueled by neat coconut oil methyl ester
(COME) injected
through conventional nozzle
(injection pressure 200 bar) and a separate electronic injector is used as
retrofit to inject methanol
(injection pressure 3 bar) at an
appropriate time at suction end after complete opening of suction valve. Tests
were conducted at
five different loads at rated
speed of 1500 rpm. With increase in methanol%, pressure variation increases per
degree of crank
revolution with progressively
increasing delay periods. Biodiesel with 5% methanol injection produced better
diffused combustion
and a good share of heat release
was observed in premixed and diffused combustion zones, besides HC and NO
emissions are
lower and consistent with minimum
change in its value as load is increasing. Smoke emission decreased at
individual loading of
engine with more methanol (up to
7%) and there is a rise in smoke at 10% methanol injection. Thus a mixture of
5% methanol
injection with biodiesel operation
is the most economical fuel combination in improving engine performance and
decreasing
emissions. |
