ABSTRACT
The aim of the current research is to experimentally investigate the performance, combustion and emission parameters of a compression ignition engine in the discharging and air preheating mode during the cold weather condition. For preheating the engine, a thermal energy storage device using phase-change material (PCM) and for preheating the inlet air an air preheater is used. From the results, it is observed that the engine temperature increases with time from 15°C to 27°C in 840 s. PCM temperature rises from 15°C to 60°C in 3000 s. during charging and while in discharging it decreases from 45°C to 30°C within the same time period. Brake thermal efficiency increases and brake-specific fuel consumption decreases with increase in load. Air-preheated diesel gives maximum cylinder pressure as compared to normal diesel. Carbon monoxide and hydrocarbon emissions are reduced during discharging and air preheating as compared to cold weather emission.
