HCCI

  • 2017 Mazda MAZDA6

    Mazda on Tuesday laid out a company-wide strategy that looks ahead to the year 2030. Chief among the plans is the introduction of the world’s first production Homogeneous Charge Compression Ignition (HCCI) engine. Mazda says the technology will appear in 2019 in a next-generation Skyactiv-X engine, though no particular models were mentioned. The redesigned Mazda 3 is rumored to be the first recipient, however. HCCI engines run on gasoline but rely on sparkless ignition via compression, like in diesel engines. Their efficiency comes from burning the mix of and air and fuel at lower...

    2019 Mazda 3 coming with world-first HCCI tech?

    Fuel-saving Homogeneous Charge Compression Ignition (HCCI) technology has been in development for decades but could soon make an appearance in a production car. Early this year, it was reported that Mazda was looking to introduce an HCCI engine in 2018. Now, Motoring is reporting that the first...

    Report: Mazda to launch HCCI engine in 2018

    Not all gasoline engines need spark plugs to ignite their fuel. A process called homogeneous-charge compression ignition (HCCI) uses compression to ignite the fuel, just like in a diesel engine. Several automakers have experimented with HCCI engines over the years, but Mazda may be the first to...

  • Could HCCI be the future of the internal combustion engine?
    Could HCCI be the future of the internal combustion engine?

    The internal-combustion engine is something with which you're no doubt very familiar. Air, spark, and fuel come together over the course of four strokes to create power and move your vehicle forward. That's for a gasoline engine; in a diesel engine, fuel is compressed until it explodes, after it's...

    A few years ago sparkless ignition or homogeneous charge compression ignition (HCCI) in gasoline engines was all the rage, with a number of major automakers including General Motors, Daimler and Volkswagen all investigating its benefits. Since then, not much has been heard of the technology whereas...

    Dirty Fuels In U.S. Hampering Next-Generation Engines, Says Mercedes-Benz

    According to Mercedes-Benz, America’s dirty fuels, namely its high sulfur content in gasoline, is the main reason why we won’t be seeing a new generation of ‘lean-burn’ engine technology anytime soon. Already on sale in Europe, these lean-burn engines run at a much leaner...

  • BMW says no to HCCI, for now

    BMW is renowned for having some of the greatest and most modern engines in the business but when it comes to one of the latest innovations in powertrain technologies BMW says it will take a "wait and see" stance. The technology we’re talking about is homogeneous charge compression ignition (HCCI), a process that works by achieving combustion of petrol with only compression of the air-fuel mix rather than using a spark plug. Both GM and Mercedes have already started testing the engine in prototypes with plans to eventually introduce it into their production cars but BMW is still sitting...

    GM trials new HCCI gasoline engines

    GM engineers are doing road-tests of a new internal combustion engine design, which the carmaker claims uses 15% less fuel than conventional petrol engines. A Saturn Aura and Opel Vectra have been fitted with new homogeneous charge compression ignition (HCCI) powerplants, and also feature direct...

    Sparkless ignition petrol engines reduce fuel usage

    Researchers at MIT have been testing a prototype of a new internal combustion engine design that’s said to improve fuel-efficiency by up to 25% and runs on regular petrol. Labeled homogeneous charge compression ignition (HCCI), the new technology works by achieving combustion with only...
