In the case of the gasoline engines we're discussing now, that is through spark ignition, which means exactly that: a spark ignites the air-fuel mixture, getting the pistons going (in diesel ...

Swapping spark plugs for nanopulses could boost engine efficiency by 20% More precise ignition events mean better fuel efficiency and fewer pollutants. Jonathan M. Gitlin – Jun 26, 2019 7:50 AM ...

Gasoline Spark Ignition Engines: Trends and Emerging Technologies - The World's Largest Suppliers are Reacting - Research and Markets June 07, 2016 06:09 AM Eastern Daylight Time ...

Known as Spark Controlled Compression Ignition, it is Mazda’s version of a homogeneous charge compression ignition (HCCI) engine, which can burn gasoline without a sparkplug firing, the way a ...

Spark plugs can only ignite the fuel at one end of the chamber. A laser ignites the fuel in the middle of the chamber instead, burning more of the fuel and improving combustion efficiency by 27 per ...

Diesel engines don’t have spark plugs; instead, they use the super-heated air created by their high compression ratios to ignite the diesel fuel as it’s injected into the cylinder.

Unlike spark-ignition gas engines or compression-ignition diesel engines that have a combustion process characterized by growth of a flame front from a single point in the combustion chamber, HCCI ...

Spark plugs have a pretty predictable life cycle, but ignition coils can be harder to track. Here's how to tell if an ...

In 2019 it will release the first commercial compression-ignition gasoline engine, dubbed SkyActiv-X. At the core of Mazda's upcoming range of engines is technology called Spark Controlled ...

The Skyactiv-X engine has been designed to have a very high compression ratio—16:1 in fact—and to use a very lean air:fuel ratio, but both of these are just below the threshold needed for HCCI ...

This isn’t as high as the most recent diesel engines, at up to 2,200 bar or 32,000 psi, but it allows the fuel to be precisely injected into the right place below the spark plug despite the high ...

Mazda's design will still use spark plugs to achieve ignition under certain conditions such as low temperatures, but it has indicated that all other issues pertaining to this design have been ...
