Fuel consumption of diesel engines combined with producer gas

Abstract

The objectives of this research were to study the fuel consumption of 1-cylinder 4-stroke diesel engines that use diesel fuel in combination with gas producers from wood charcoal and the amount of black smoke from exhaust gas in both cases. The gas producer is made from a 60-litre updraft gasifier with water cooler. Experiments compared fuel consumption at engine speeds of 700 rpm, 800 rpm, 900 rpm, 1,000 rpm, 1,100 and 1,200 rpm. Experimental results show that the gas producers using charcoal as raw materials for gas production can be used as dual fuel well at all engine speeds in experiments. Diesel fuel savings of up to 178 ml/h (at 900 rpm) can reduce diesel consumption by up to 53%. Part of reducing the specific pollution of black smoke, it was found that dual fuel consumption significantly reduced black smoke from 45% to 38%.
