Abstract

In this study, change in brake
power (BP) of a variable compression spark ignited engine was investigated with
different spark plugs and hydrogen enrichment. The tests were carried out with
a four stroke, single cylinder, naturally aspirated, variable compression ratio
(VCR) engine. Two different compression ratios (CR) of 8.5:1 and 10:1 under %50
part throttle condition were implemented throughout the experiments. Moreover,
engine loads of 8 Nm, 13 Nm and 17 Nm were applied to evaluate effects of
different spark plugs and hydrogen usage at different engine loads. Copper,
iridium and platinum spark plugs were tested for each experiment condition. In
addition, hydrogen was added through the intake manifold with flow rates of 0,
2 and 4 lit/min to enhance combustion of VCR engine. According to test results,
iridium and platinum spark plug usage, hydrogen addition and higher compression
ratio improved BP significantly. This variance occurred more obvious with
platinum spark plug usage comparing to iridium spark plug. In addition, effects
of spark plug alteration, hydrogen addition and higher CR on enhancement of BP
were comparatively lower at higher engine loads.
