The current study investigates the fuel properties, performance
and emission characteristics in a variable compression ratio (VCR) diesel of
the biodiesel produced from the waste cooking oil (WCO). The WCO samples were
collected from the university and converted to biodiesel fuel with a two-step
transesterification reaction. The fuel property tests showed that the
properties of the WCO biodiesel were within the biodiesel standards. Diesel,
WCO biodiesel and diesel-WCO biodiesel blend (B20) was used as fuel in a VCR
engine. The performance and emission characteristics of the engine were
measured at two different compression ratios (14:1 and 16:1) under partial load
conditions. The experimental results showed that WCO biodiesel slightly
decreased the brake thermal efficiency and thus increased specific fuel consumption.
Biodiesel usage improved CO emissions up to 21,75% compared to diesel fuel.
But, biodiesel usage increased CO2 and NOx emission due
to higher combustion temperature and extra oxygen content of the biodiesel.
