Effect Of Compression Ratio On Partially Premixed Charge Compression Ignition Engine Fuelled With Methanol Diesel Blends–An Experimental Investigation
Abstract
The effects of compression ratio on premixed charge compression ignition engine fuelled with methanol diesel
blends were investigated. The test was carried out with different compression ratio. The compression ratio (r) was obtained
using different piston heads (r). The premixed charge compression ignition engine was modified by using four-stroke, air
cooled, single-cylinder diesel engine and also the performance, combustion and emission Characteristics were studied. The
experimental results of PCCI engine indicated that an overall brake thermal efficiency was increased to 2% using methanol
diesel blends at compression ratio of 19.5 than neat diesel. The reduction of overall Oxides of Nitrogen was observed at
compression ratio of 19.5 by 56%. The methanol diesel blends results with different compression ratios indicated that
Carbon monoxide and unburned hydrocarbon emissions were increased 10% in 19.5 compression ratios. An overall
experimental results indicated that compression ratio of 19.5 was suitable for alternate fuel operations in PCCI engine and
had good combustion and emission characteristics. The exhaust emissions, heat release rate were analysed using AVL
software systems, AVL five-gas analyzer and AVL smoke meter. And wefocuses on the trends of coupling effects on noise
in delay estimation.
