Due to special working conditions, diesel engines often need run stably for a long time at high power operating conditions. As the core of engine moving parts, piston needs be exposed temperature time. Based on problem excessive maximum point certain type engine, this paper discussed protective effect using different thicknesses Mullite thermal barrier coating top surface piston, by method hard...

The paper presents the effects of blend injection and dual strategies on mixture formation combustion syngas-biogas-hydrogen fueling engine working in solar-biomass hybrid renewable energy system. research was performed by simulation method a retrofitted Honda GX200 spark-ignition engine. results show that at end compression process, case 50% syngas-50% biogas, fuel-rich zone positioned top cha...

investigations are carried out to evaluate the performance of a low heat rejection (lhr) diesel engine consisting of air gap insulated piston with 3-mm air gap, with superni (an alloy of nickel) crown and air gap insulated liner with superni insert with different operating conditions of crude jatropha oil with varied injection timing and injection pressure.  performance parameters of brake ther...

Diesel engines being inferior in their emission characteristics are under greater scrutiny. Intensive research efforts are ongoing for improving fuel consumption and exhaust emissions from diesel engines. For improving performance of engine, Ceramic based Thermal barrier Coating plays a major role. Tests were performed on four stroke, single cylinder, DI diesel engine whose piston crown, cylind...

The engine piston is subjected to very high temperature during the combustion process, and it difficult control stability of geometry at elevated temperature. was analysed by finite element method with steady-state conditions for three different types approach it, where influence alloying aluminum piston, surface coating, its impact on thickness variation followed holes coating have been in det...
