متن کاملImproved efficiency of CNG using hydrogen in spark ignition engine
Experimental investigations carried out on a single-cylinder four-stroke motorcycle spark ignition engine operating on gasoline and natural gas are reported in the present paper when compressed natural gas (CNG) and hydrogen were used as fuel. The investigations were carried out by mixing a small percentage of hydrogen (5 to 30%) with CNG and supplied to the engine. Hydrogen and CNG were mixed ...
متن کاملAir Charge Estimation in Turbocharged Spark Ignition Engines
Turbocharged (TC) spark-ignited (SI) engines are popular as they combine high power output with good fuel economy. Furthermore, their emissions can be successfully reduced using a three way catalyst (TWC) provided that the airfuel ratio is precisely controlled. As the air-fuel ratio depends on the precision of the air charge estimate, this thesis is devoted to the systematic improvement of the ...
متن کاملThe Effect of Turbulent Mixing on Compression Ignition of a Lean Hydrogen/Air Mixture
The influence of a turbulent spectrum of the temperature field on compression ignition at constant volume under homogeneous charge compression ignition engine conditions is studied by direct numerical simulation with complex chemistry. In particular the dependence of overall ignition progress on initial mixture conditions and turbulence parameters is determined. The propagation speed of ignitio...
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...
