Abstract: This invention mainly focused on improvement in thermal efficiency, reduction in specific fuel consumption, and harmful exhaust gas emissions in IC engines. It is achieved by providing proper thermal insulation of combustion chamber parts which helps to reduce heat energy dissipated to coolant fluid effectively. The combustion chamber components of the piston head and cylinder liner are coated with an equivalent proportion of YSZ and Al2O3. The piston head was given a coating of 100micron (0.1mm) thickness and the cylinder liner was given a coating of 200micron (0.2mm) thickness. This invention is not only effective for fossil fuels of petrol and diesel but also useful for the usage of biodiesel without any modification in internal combustion engine.
Description:In recent decades, a wide number of research programs are conducted in automotive industries specifically for decreased engine fuel utilization and environmental pollution. The extent of energy derived from diesel is not at an expected level due to the different unresolved parameters in the existing combustion chamber design. The configuration of the CC itself, a lack of appropriate agitation, depleted oxygen at the intermediate level, lower combustion temperature, CR, and the advancement of the injection period are all key inhibitory characteristics. The combustion temperature is probably considered to be one of the most significant factors among the above-mentioned parameters. The complete interaction of the hydrocarbons with the Oxygen is not realizable during the combustion time. As a result, covering CC parts with lower heat conduction substances has been a significant focus of research to address this shortcoming. Based on all these facts mentioned, the present invention is exclusively concentrated on the coating of the combustion chamber components with ceramic materials of Yttria stabilized Zirconia (YSZ) and Alumina (Al2O3). , C , C , C , C , Claims:Thermal barrier coated combustion chamber in Internal Combustion Engine
