The automaker confirmed development work on a new range of straight-six engines that will be mounted longitudinally for RWD vehicles, essentially adding two more cylinders to the company's SkyActiv-X four-cylinder petrol engine featuring compression-ignition technology.
Their topics include compression-ignition and spark-ignition engines, on-board diagnostics and vehicle control modules, diagnosing with an oscilloscope, electronic fuel-injection output devices, and supercharging and turbocharging.

The CX-30 will come with Mazda's latest Skyactiv-X compression-ignition petrol engines - which are claimed to be as economical as diesels - with an electric-motor powered mild hybrid system also on offer.
A CFD-guided combustion system optimization was conducted using a gasoline-like fuel (AKI=58, denoted as "naphtha") for a heavy-duty mixing-controlled compression-ignition engine.
However, maintaining combustion temperature throughout the operating envelope has been problematic other than for compression-ignition diesels.
For the transportation sector, we assumed that all gasoline and ethanol would be consumed in spark-ignition engines, whereas diesel and biodiesel would be con sumed in compression-ignition engines.
Thus, simultaneous chemical oxidation of HC and CO in an HCCI engine is much easier than simultaneous chemical reduction of N[O.sub.x] and oxidation of PM in a Compression-Ignition Direct-Injection (CIDI) engine.
In Austria's case it concerned Commission Directive 2008/74/EC amending Directive 2005/55/EC of the European Parliament and Council on the approximation of member states' legislation on measures to limit the emission of gaseous and particulate pollutants from compression-ignition engines for use in vehicles and gaseous pollutants from positive-ignition engines fuelled with natural gas or liquefied petroleum gas for use in vehicles.
The application of ethanol as a supplementary compression-ignition fuel may reduce environmental pollution, strengthen agricultural economy, create job opportunities, reduce diesel fuel requirements and thus contribute in conserving a major commercial energy source.
In March, the EPA finalized more stringent emissions standards for locomotives and marine compression-ignition engines.
