ABSTRACT
This study investigates the characteristics of combustion, power, torque, effi ciency, diesel fuel consumption when using Biodiesel from catfish and basa fish fat. Along with emissions such as NOx, HC, CO and CO2, smoke opacity will be studied experimentally in an EMEI Model 185N diesel engine, designed capacity: 5.88 kW.
The applicability of the use of Biodiesel from catfish oil and tra fish is checked. The research results show that this biofuel corresponding to the 20% blend ratio has a maximum CO reduction of 50% at 1700 rpm, NOx decreases most at the maximum reduction rate surveyed. at 1000 rpm it is 10%, the smoke level increases at low speed then gradually decreases the maximum decrease of 6% at 1900 rpm, HC decreases 28% at 1700 rpm, Average CO2 reduction for diesel Bio is 9.03% at all engine speeds. The average reduction of B2 0, B40 and B60 fuel mixes is 3.8%, 8.2%, 15.1%. In terms of power and torque, which is 2 to 3% lower than that of diesel fuel, the difference is not much. Empirical research results show that it is entirely possible to apply biofuel from fish fat used for internal combustion engines without changing engine structure. During operation, the engine is stable as well as the emissions are different from the traditional fuel in the direction of reduction.
