Climate change brought about by the emission of Greenhouse Gases (GHG) has shone a spotlight on role internal combustion engine. These engines are significant contributors to GHG emissions. However, there have been recent improvements in their design. Natural gas produces lower emissions during combustion, making it suitable as fuel engines. Aside from impact gasoline and diesel, collapse Niger...

This work focuses on the numerical and experimental analysis of turbocharger selection boost pressure effects a CNG-fueled spark-ignition engine. Because this, investigations are carried out influence downsized compression ratio 10.5:1 at different pressures compared with naturally aspirated 12.5:1. In order to perform experimentation, twin-cylinder, port fuel-injected, CNG engine 15.5 kW 3400 ...

Small diesel engines are widely used for commercial vehicle and passenger car applications due to their higher torque requirements, fuel economy, and better thermal efficiency. These engines are exposed to different operating and environmental conditions and hence emissions from these engines are erratic. Strategies are required to enhance performance and reduce engine-out emissions considering...

in the present work, the simultaneous effects of fuel injection rate and injection of air jet into the combustion chamber on exhaust emissions, combustion process and performance parameters in a direct injection diesel engine were investigated. in order to create an air jet, a design was presented in which a secondary chamber (air cell) was created inside the cylinder and was joined to the main...
