  • High pressure direct fuel injection as a solution for performance enhancement in two-stroke spark-ignition engine
    Gopal Kumar Deshmukh, Ameenur Rehman, Rajesh Gupta
    Energy Sources Part A Recovery Utilization and Environmental Effects, 2025
    Two-stroke spark-ignition engines mainly suffer from the poor fuel economy and high exhaust emission. However, the methodology presented here has adequate potential that can salvage these engines from becoming extinct as the compactness and their power to weight ratio are the two favorable characteristics that provide sufficient leverage for their salvation. The present paper makes an attempt to investigate the influence of the direct fuel injection at moderately high pressure on two-stroke spark-ignition engine performance as well as emission. In this paper, the conventional carbureted two-stroke spark-ignition engine has been modified with a high pressure fuel injection system installed on the cylinder head. The injection of fuel is timed with the closure of exhaust port shut by the piston, which helps in saving fresh fuel from getting short-circuited through the exhaust port. The experimental investigation has been carried out on the engine at various throttle positions of both carburetor as well as fuel injector for different speeds. The experimental measurements revealed that results of direct fuel injection mode compared well as opposed to the carburetor mode. It was observed that brake power exhibited significant improvement approximately 20.1% as compared to the conventional engine. The brake thermal efficiency is found to be 16.3% higher than that of the conventional engine. Above all, fuel loss through short-circuiting noted to have reduced brake specific fuel consumption by 17%. The direct injection system has shown 27.5 and 88.5% reduction in carbon monoxide and unburned hydrocarbons emission, respectively, as compared to the conventional engine.

  • Impact of temperature on the spray characteristics of Jatropha curcas biodiesel and diesel fuel blends
    Gopal Kumar Deshmukh, Ameenur Rehman, Rajesh Gupta
    Journal of Testing and Evaluation, 2021
    There is an increasing demand of energy because of an increase in the number of vehicles with internal combustion engines, because of which industrial and automotive fields are concerned about fossil fuel depletion, environmental issues, and energy conservation. These challenges force the world to explore other alternative sources of energy. The extensive use of biodiesel as compression ignition engine fuel has further compelled the researchers to regulate the emission and improve the engine performance. Fuel spray behavior affects mixture formation, and this affects engine combustion and performance. This research work involves the evaluation of the relationship between spray parameters of used Jatropha curcas biodiesel fuel, including spray penetration, cone angle, and preheating temperature, compared with diesel fuel, conducted at ambient condition. In addition to this, the high-speed spray pattern photography is undertaken by using single-hole and multi-hole injectors. The spray behavior is analyzed through spray parameters such as spray cone angle and spray penetration for all test fuels. The fuel temperature has a strong relationship with spray behavior at high temperatures; as the fuel temperature increases, the spray tip penetration decreases due to the evaporation of the fuel having a low boiling point and good fuel atomization, which leads to smaller droplets and an increase in spray cone angle with the increase in temperature.
