CI engine performance during cold weather condition using preheated air and engine by waste energy

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.
