The first use of the all-new SKYACTIV-G 2.0-liter inline 4-cylinder gasoline engine was in the 2012 Mazda3 and the 2013 Mazda CX-5. Designed as an integral part of the entire range of SKYACTIV technologies, the SKYACTIV-G engine provides the stirring performance of a race-bred gasoline engine with the fuel efficiency of a diesel. As a result, in the Mazda3 and CX-5 - with more joining in the future - the SKYACTIV-G engine simultaneously acheives up to a 15% increase in torque and 15% less fuel consumption compared to Mazda's MZR 2.0-liter gasoline engine.

Breakthrough SKYACTIV-G technologies:

Direct Fuel Injection

The SKYACTIV-G 2.0-liter engine uses an advanced firect-fuel injection system with multi-hole injectors that spray fuel directly into the cylinders at high pressure. The result is a cooler and denser fuel charge, which provides maximum power and fuel efficiency while helping to eliminate pre-ignition.

High Compression Ratio

A higher compression ratio leads to higher power output. The SKYACTIV-G is the first gasoline engine in mass production with a high 13.0:1 compression ratio, which maximizes torque, fuel efficiency and overall drivability - all with lower emissions.

Volcano-Top Pistons

An ingenious volcano-like pocket at the top of each piston allows the combustion process to begin in the high-compression environment without excessive heating of the piston. The result is improved combustion, reduced energy loss and the reduced possibility for pre-ignition.

Electrical Sequential Valve Timing

The SKYACTIV-G engine's Electric Sequential Valve Timing opens the valves at precisely the right instant for maximum power and fuel economy, with minimal emissions. This precise valve control reduces energy losses (also known as "pumping" losses) that can occur when air unnecessarily moves back and forth within the intake system.

4-2-1 Exhaust Manifold

Besides removing waste gases from the engine, the exhaust system must also remove combustion heat, which can otherwise raise the temperature of the next air/fuel charge, leading to unwanted pre-ignition, or knock. To do this, the SKYACTIV-G engine in the 2013 CX-5 has a long 4-into-2-into-1 manifold that extracts exhaust-gas pulses from each cylinder with great efficiency.
