Spark Plug with Integrated Chamber

MATEC Web of Conferences, 2018
Spark plug with integrated chamber increases the quality of ignition of homogenous mixture in the engine cylinder. Very small amount of burning mixture bursts (outflows) from chamber (so-called flame jet ignition) which heads into faster initial phase of

Optical multi-spark ammonia combustion engine: numerical analysis and validation

Frontiers in Mechanical Engineering
Ammonia (NH3) stands out as a promising candidate for fueling internal combustion engines, owing to its high hydrogen content and well-established production and transport infrastructure. Nevertheless, its inherently low flame speed and reactivity pose a

Performance, emission and combustion characteristics of a branched higher mass, C3 alcohol (isopropanol) blends fuelled medium duty MPFI SI engine

Engineering Science and Technology, an International Journal, 2017
With growing concerns about environmental pollution caused by automobiles, biofuels containing oxygen – also known as oxygenates – are being researched very rigorously. In this article, we have inspected the use of isopropanol/gasoline blends, as fuel in

Generation of entropy in spark ignition engines

, 2007
Recent engine development has focused mainly on the improvement of engine efficiency and output emissions. The improvements in efficiency are being made by friction reduction, combustion improvement and thermodynamic cycle modification. New technologies such as Variable Valve Timing (VVT) or Variable Compression Ratio (VCR) are important for the latter.
