The world’s first production petrol unit to exploit the benefits of diesel-like compression ignition, new 2.0-litre Skyactiv-X M Hybrid is the next step in Mazda’s multi-solution approach to reducing emissions.
Skyactiv-X is characterised by Mazda’s revolutionary Spark Controlled Compression Ignition (SPCCI). This new engineering concept allows the engine to switch seamlessly between conventional spark ignition and compression ignition combustion by using a spark to trigger both types of combustion in different ways.
In SPCCI mode, a split injection process creates separate zones of fuel-air mixture inside the combustion chamber. First, a very lean fuel to air mixture is injected into the chamber during the intake stroke. Then a zone of atomised fuel is precisely injected directly around the spark plug during the compression stroke.
Skyactiv-X also features the Mazda M Hybrid system. This has a belt-driven integrated starter generator (ISG) and a 24V lithium-ion battery. It uses energy recovered during deceleration, functioning as an electric motor, to assist the engine.
We will borrow vehicles from Mazda to carry out our normal road tests and give our opinions immediately afterwards.
