Mazda has a long history of building its own Diesel engines, with the exception of a few units that were built under license.




These three engines (GA/GB/GC in Perkins' internal parlance) were developed especially for Mazda and were never offered by Perkins themselves.

All of these engines have cast iron blocks and heads, two overhead valves per cylinder driven by maintenance-free timing gears, crossflow heads, are indirect injection. US-market B2200 and Ford Ranger trucks - and possibly the others as well - had rotary Bosch VE-style injection pumps, built by Diesel Kiki under license from Bosch.


A diesel variation of the 2.0 L (1,998 cc) FE engine which shares its square internal dimensions of 86 mm × 86 mm (3.39 in × 3.39 in) bore and stroke - it is virtually the same block, with identical bell housing pattern and block dimensions. This could be a testament to the F-block's strength as it was over-built for naturally aspirated duty. Its alloy head is entirely different though, with valves directly actuated rather than the rockers of the FE. The glow plugs are located in remote combustion chambers, with fuel delivered by a mechanical pump. The RF is light, with the original naturally aspirated version weighing in at 146 kg (322 lb), 10 kg (22 lb); more than the FE. [2] The RF The RF and R2 continue production to this day[ needs update ] as the MZR-CD, with counter-rotating balance-shafts mounted between the engine block and oil pan as well as much evolved head and direct-injection technology. The RF is a SOHC, two valves-per-cylinder engine. One of Mazda's more popular diesel engines, it was also available with a pressure wave supercharger called Comprex.


  • 61 PS (45 kW; 60 hp) at 4000 rpm, 12.3 kg⋅m (121 N⋅m; 89 lb⋅ft) at 2750 rpm (DIN, naturally aspirated EU version) [3]

RF 1998

Latest emission improved version used in Mazda 323 adopts a new swirl chamber with an enlarged volume, revised swirl-chamber-to-main-chamber ratio and a narrower throat area. Engine produces 52 kW (71 PS; 70 hp) at 4500 rpm on a raised 21.7:1 compression ratio, and has an exceptionally wide spread of torque throughout its range, peaking with 128 N⋅m (94 lb⋅ft) at 3000 rpm.

RF-T DI 1998 (2.0 DiTD)

A direct-injection turbo version 101 bhp (75 kW; 102 PS) with four valves per cylinder, called the DiTD was introduced in the June 1998 Mazda 626 Wagon 2.0 DiTD. Engine has SOHC valve train with rocker arms and mechanically adjusted screws (no hydraulic valve lifters), with Denso V5 rotary injection pump and Denso PCM.

There were three power versions:

Engines were mounted in:

RF 2002 (2.0 MZR-CD)

Next evolution of RF engine with common rail direct-injection was introduced in June 2002 European version Mazda 6 with output power 89 kW (121 PS; 119 hp) or 100 kW (136 PS; 134 hp) (both at 3500 rpm), depending on engine version (only difference between the two diesel drivetrains is the shape of their respective torque curves, the larger of the two engines being flatter). 2002 RF Mazda diesel engine includes new dual-mass flywheel and common rail Denso injection with max. pressure of 1800 bar, pilot and post-injection for operating smoothness and soft and acoustically unobtrusive combustion. Both versions have same compression ratio 18.3:1. Torque output (both versions have same maximum 310 N⋅m (229 lb⋅ft) at 2000 rpm), fuel efficiency and NOx emissions were improved by using:

Combined fuel economy is achieving 6.5 L/100 km (43 mpgimp; 36 mpgUS) and emission rating Euro Stage III (D4) with on a regular basis mounted catalytic converter with Lambda probe and exhaust-gas recirculation system (EGR). Engines were mounted in (in order of appearance):

RF 2005 (2.0 MZR-CD)

Production of improved, cleaner and more powerful common rail direct-injection turbocharged version of Mazda RF engine was started with July 2005 Mazda 6 facelift. This drivetrain still has most of typical features of its predecessor including belt-driven SOHC valve train with rocker arms and mechanically adjusted screws (in contrast to frequently mismatched, absolutely different ZSD or PSA DW10 Ford Duratorq engines). Mazda applied several technologies to this MZR-CD engine to achieve Euro Stage IV:

There were two power versions of this engine: Standard Power 89 kW (121 PS; 119 hp) at 3500 rpm and a maximum torque of 320 N⋅m (236 lb⋅ft) at 2000 rpm, High Power 105 kW (143 PS; 141 hp) at 3500 rpm and a maximum torque of 360 N⋅m (266 lb⋅ft) at 2000 rpm. Both versions come with a DPF system standard, which traps soot in a coated ceramic filter. As soon as the filter's storage capacity is exhausted, exhaust gas temperature is raised for a short period (using only diesel pre and post-injection techniques, not any fuel burner additive) and the particles burn off. As a result, the RF 2005 engines emit 80 percent less particulate matter than required by Euro Stage IV standards. Engines were mounted in (in order of appearance):

RF 2007 (2.0 MZR-CD)

Slightly detuned 103 kW (140 PS; 138 hp) at 3500 rpm and 330 N⋅m (243 lb⋅ft) at 2000 rpm) version of RF 2005 engine was introduced in November 2007's second generation Mazda 6. Newly calibrated powertrain control module mapping resulted in better drivability, fuel efficiency and emission performance. This engine has changed layout of the intake/exhaust, with more efficient EGR cooler, better DPF and combined fuel consumption 5.6 L/100 km (50 mpgimp; 42 mpgUS), less than its predecessor. Engine was mounted in (in order of appearance):

R2 2008 (2.2 MZR-CD)

New generation RF-based MZR-CD 2.2-litre turbo diesel engine (stroke was lengthened by 8 mm (0.31 in) in comparison to the MZR-CD 2.0 RF engine) was introduced in November 2002 and this powertrain is planned to totally replace RF 2007 and RF 2005 in the future with three (or more, see below) power versions:

Mazda F engine Motor vehicle engine

The F engine family from Mazda is a mid-sized inline-four piston engine with iron block, alloy head and belt-driven SOHC and DOHC configurations. Introduced in 1983 as the 1.6-litre F6, this engine was found in the Mazda B-Series truck and Mazda G platform models such as Mazda 626/Capella as well as many other models internationally including Mazda Bongo and Ford Freda clone, Mazda B-series based Ford Courier, Mazda 929 HC and the GD platform-based Ford Probe

The Mazda B-series engine - not to be confused with the Mazda B-Series truck - is a small-sized, iron-block, inline four-cylinder with belt-driven SOHC and DOHC valvetrain ranging in displacement from 1.1 to 1.8 litres. It was used from front-wheel drive economy applications to the turbocharged full-time 4WD 323 GTX and rear-wheel drive Miata as well as numerous other models. The Mazda B-series is a "non-interference" design, meaning that breakage of its timing belt does not result in damage to valves or pistons, because the opening of the valves, the depth of the combustion chamber and the shaping of the piston crown allow sufficient clearance for the open valves in any possible piston position.
