Engine Duratec HE 2.0/MZR LF

The design of the Duratec HE / MZR LF 2.0L engine is largely the same as the 1.8-liter version, but the cylinder diameter in them is already 87.5 mm. The MZR series engine was developed by Mazda engineers for the LF models and used by Ford in a collaboration. If we compare the 2.0-liter version with the 1.8-liter, then the larger engine is better in all respects. It works more powerful, but quiet and smooth, no floating speed. The timing chain drive increases the reliability of the unit, the resource of which is designed for 350,000 kilometers.

Engine SkyActiv-G 1.5

The Mazda SkyActiv 1.5 engine is a relatively new engine from the Skyactive series, which replaced the MZR in general, and 1.5 liters. in particular replaces the outdated 1.6 Z6. SkyActiv 1.5 l. is presented in two versions, with a Compression ratio of 13 and a power of 100 hp. and with a degree of 14, and a power of 120 hp. In both versions, the engine has direct fuel injection and a variable valve timing system on the intake and outlet shafts Dual S-VT. This is an engine with a lightweight SHPG, pistons with a special shape for maximum optimization of the combustion process and reducing the possibility of detonation.

Engine SkyActiv-G 2.0

The Mazda SkyActiv-G 2.0 engine is designed for installation on Mazda 3, Mazda 6 and Mazda CX-5 cars. The engine has been produced since 2011. The engine was intended to replace the 2.0-liter Ford engine (index MZR LF). The SkyActiv 2.0 engine has the same range of innovative technologies as the SkyActiv 1.5 engine. There is a system of variable valve timing Dual S-VT on two camshafts, an outlet manifold that provides the effect of dynamic purging of outlet gases in the combustion chambers due to the optimal length and configuration 4-2-1.

Engine Mazda 3 MZR Z6

The Mazda 3 (MZR Z6) engine is assembled according to the classical scheme with an in-line arrangement of 4 cylinders. It is a further development of the B6D powertrain, which was manufactured at the Hiroshima Plant. Now this plant produces all engines for the Mazda 3 car. The cylinder block of the MZR Z6 engine is made of durable aluminum alloy. The timing is driven by a lamellar steel chain, which does not need to be replaced for a long time (mileage of at least 250 thousand km). It is stretched using an automatic tensioner.
