- Abstract
Diesel engine is efficient and economical, but it is large in size and non-friendly environmental. Liquefied petroleum gas (LPG) is available at a lower price than other fuels and environmental-friendly. One of the important research topics that have been updated is the use of LPG in diesel engines. The LPG has a high heat value, and its gaseous state makes mixing with air simple and has perfect redound of combustion to increase the power output; LPG also helps to fully consume the fuel and thus reduces emission and helps to harvest the total energy found in the fuel. It is designed in a new electronic control unit (ECU) and is used of the LPG injection timing and duration while opening the air intake valve into the combustion chamber and a magnetic sensor is installed on top of a single cylinder diesel engine with air-cooled. The test engine is run in four fuel modes and during the start, D-100, the fuel is used as LPG-25, LPG-50 and LPG-100. The test was under loads of 0%, 25%, 50%, 75% and 100% at different speeds of 1000, 1500 and 2000 rpm. At the engine speeds of 1000, 1500, 2000 rpm compared to D-100 fuel, the thermal efficiency proved better at time of using LPG-50. The fuel is increased about by (0.99%, 0.92%, 1.29%)þ and the brake specific fuel consumption (bsfc) is decreased at 9.81%, 9.4% and 9.68% respectively. A decrease in emissions, NOx, HC, CO and CO2 are observed in all operating modes with LPG and the best emission reduction situation is LPG-50.
