Opis:
Jatropha oil was blended with kerosene in ratios; JOK0, JOK20, JOK30, JOK40 and JOK50 and benchmarked against conventional diesel fuel. The blended fuel samples was test-run on a TD110-TD115 TQ small CI engine test rig, and emission levels for the fuel samples were examined using an SQV automobile exhaust gas analyser. The JOK20 fuel sample offered a better performance in terms of higher BP, BTE, and EGT followed by; JOK30, JOK40 and JOK50 blends; and also exhibited lower SFC, BSEC and AFR, hence less fuel consuming than diesel fuel. A reduction in CO emission was recorded for JOK20, and a significant cut was also observed for JOK30, JOK40 blends with load increase.; while, JOK30, JOK40 and JOK50 samples exhibited higher CO2 and lower UHC emission levels than diesel. No traceable level of NOx emission was recorded for JOK20 fuel sample.

Opis:
The article presents experimental test results of a DI single-cylinder, air-cooled diesel engine FL 511 operating with the normal (class 2) diesel fuel (DF), rapeseed oil (RO) and its 10%, 20% and 30% (v/v) blends with aviation-turbine fuel JP-8 (NATO code F-34). The purpose of the research was to analyse the effects of using various rapeseed oil and jet fuel RO90, RO80 and RO70 blends on brake specific fuel consumption, brake thermal efficiency, emissions and smoke of the exhaust. The test results of engine operation with various rapeseed oil and jet fuel blends compared with the respective parameters obtained when operating with neat rapeseed oil and those a straight diesel develops at full (100%) engine load and maximum brake torque speed of 2000 rpm. The research results showed that jet fuel added to rapeseed oil allows to decrease the value of kinematic viscosity making such blends suitable for the diesel engines. Using of rapeseed oil and jet fuel blends proved themselves as an effective measure to maintain fuel-efficient performance of a Didiesel engine. The brake specific fuel consumption decreased by about 6.1% (313.4 g/kW·h) and brake thermal efficiency increase by nearly 1.0% (0.296) compared with the respective values a fully (100%) loaded engine fuelled with pure RO at the same test conditions. The maximum NOx emission was up to 13.7% higher, but the CO emissions and smoke opacity of the exhaust 50.0% and 3.4% lower, respectively, for the engine powered with biofuel blend RO70 compared with those values produced by the combustion of neat rapeseed oil at full (100%) engine load and speed of 2000 rpm.
