heat balance of a natural gas fueled spark ignition engine with a turbocharger
in this paper, the heat balance of an engine was investigated experimentally. the experimental work was conducted on the ef7 natural gas fueled and turbocharged engine. the main goal was to develop an empirical equation to be able to predict the heat balance of the engine at various loads and conditions. the data were collected at four different conditions, two different loads and two different...
متن کاملEffect of electrode erosion on the required ignition voltage of spark plug in CNG spark ignition engine
In this article, the electrode erosion and the gap growth of spark plugs were measured on of a CNG fueled engine after durability tests. Then, the required ignition voltage and the spark quality were investigated by a spark plug test rig. Considering results of measurements, the gap growth increased as the running time increased. Thus, the gap growth of spark plugs with 200 and 280 hours runnin...
متن کاملImproved Knock Detection Method Based on New Time-Frequency Analysis In Spark Ignition Turbocharged Engine
Premature combustion that affects outputs, thermal efficiencies and lifetimes of internal combustion engine is called “knock effect”. However knock signal detection based on acoustic sensor is a challenging task due to existing of noise in the same frequency spectrum. Experimental results revealed that vibration signals, generated from knock, has certain frequencies related to vibration resonan...
متن کاملThe Effect of Ignition Timing on Methanol Blended Spark Ignition Engine
The objective of the present work is to evaluate whether variable ignition timing can be effect on exhaust emission and engine performance of a spark ignition engine. The study describes some results of research in the area of spark ignition engine and is assessed by studying its performance and emission characteristics relative to that of conventional ignition engine using gasoline and methano...
