Study the consumption and cost of using LPG in diesel engines

Abstract

Diesel fuel used in diesel engines is more expensive than other fuels used in internal combustion engines and causes emissions that affect the environment and health. The researchers have established the possibility of providing fuel that operates in diesel engines and that is less expensive and pollution than diesel fuel. Iraq is one of the oil and natural gas producing countries, the choice of LPG makes the choice available because of the positives it possesses, which are low price, high thermal value and the possibility of mixing with air easily and low emissions, it is considered environmentally friendly and also maintains the engine as it does not contain high sulfur compared to diesel fuel. The Electronic Control Unit (ECU) designed a new and used to adjust the injection of LPG 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 was operated with as D-100 and LPG-50. The diesel quantity was changed by is flow rates of injectors 100% and 50% and replaced by LPG .The test was for each condition load 0%, 25%, 50%, 75% and 100% at different speeds 1000,1500 and 2000 RPM.The best case for BSFC is when the engine is running in dual fuel mode and at 1000 RPM, where the fuel improves by 9.81%. decreased that per hour running cost per liter of dual fuel compared to pure diesel fuel at speeds 1000, 1500 and 2000 RPM by 14.45%, 15% and 15.31% respectively.
