Effect of Spark Timing and Load on Combustion and Emission Characteristics in Jet Controlled Compression Ignition 2015-01-1793

A novel combustion system called Jet Controlled Compression Ignition (JCCI) is investigated to directly control the combustion phasing of premixed diesel compression ignition. Experiments were conducted on a single-cylinder naturally aspirated diesel engine at 3000r/min without EGR. The experimental results showed a good linear relationship between spark timing in the ignition chamber and CA10 and CA50, which indicated the ability for direct combustion phasing control in premixed diesel combustion. The NOx and soot emissions gradually changed with the spark advance angle. Then, load sweep experiments were performed with fixed spark timing. The results showed the onset of combustion was almost unchanged over a wide load range. Additionally, NOx emission was greatly reduced at all test loads compared with the original engine. Soot emission was reduced at a comparatively high load while similar with that of the original engine at low loads. The maximum reduction of NOx and Soot were both over 90%.
