What is the model of Mazda 3 engine?

There are two kinds of Mazda engines: one is 1.6 liter naturally aspirated engine, and the other is 2.0 liter naturally aspirated engine. Both engines are equipped with multi-point injection technology and use aluminum alloy cylinder heads and cylinders. From the engine structure, 1.6 and 2.0 engines are all in-line four-cylinder naturally aspirated double overhead convex shafts, with a compression ratio of 10, which tends to show high speed. Compared with 2.0 engine, 1.6 engine cancels VIS variable intake manifold and electronic throttle, and only VVT variable valve and VICS can be changed into vortex system, which is obviously different from 2.0 engine in power and fuel economy.
