Effect of Low Thermal Conductivity Materials on Performance of Internal Combustion Engine- A Review And Experimentation
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 1
Abstract
The combustion chamber of diesel engine is maintained hot with the provision of low thermal conductivity materials, so as to burn high viscous vegetable oils, biodiesel and low cetane alcohols. Experiments were conducted on different combustion chambers of diesel engine like low insulated engine (LIE), medium insulated engine (MIE) and high insulated engine (HIE).with pongamia biodiesel. LIE contained ceramic coated cylinder head, while MIE consisted of an air gap insulated piston with superni (an alloy of nickel) crown and air gap insulated liner with superni insert. HIE had the combination of LIE and MIE. The provision of low thermal conductivity materials like air, partially stabilized zirconium (PSZ) and superni resulted in semi adiabatic diesel engine which prevented heat loss to the coolant thereby increased thermal efficiency and reduced particulate emissions. Comparative studies were made with different combustion chambers and also with conventional engine (CE) at recommended injection timing. The performance of the insulated engine improved with an an increase of degree of insulation.
