Effects of laser parameters on laser ignition in an internal combustion engine
Recent research in laser-induced ignition (LI) of air-fuel mixtures in internal combustion (IC) engines has shown there to be many potential advantages over conventional electrical spark ignition (SI). Spark plugs offer only limited possibilities for optimising engine efficiency, due to their fixed position within a cylinder and the protrusion of electrodes which disturb the cylinder geometry a...
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...
متن کاملFormaldehyde for the Premixed Compression-ignition Engine - an Additive for Ignition-timing Control -
Lean fuel/air mixtures with various fuel/fuel ratios between methane and n-butane were supplied to a premixed compression-ignition engine (i.e. homogeneous charge compression ignition engine, HCCI) with or without supplementary gaseous formaldehyde induction as an ignition controlling additive. In the no additive case the methane and butane function as the two fuels in the high/low-octane two-f...
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 کاملLaser Plasma-initiated Ignition of Engines
Laser ignition is considered to be one of the most promising future ignition concepts for internal combustion engines. It combines the legally required reduction of pollutant emissions and higher engine efficiencies. The igniting plasma is generated by a focussed pulsed laser beam. Having pulse durations of a few nanoseconds, the pulse energy Ep for reliable ignition amounts to the order of 10 ...
