RF:
A diesel variation of the 1998 cm3 FE engine which shares its square internal dimensions of 86 mm (3.4 in) bore and 86 mm (3.4 in) 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. The RF and R2 continue production to this day 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.
Applications:
-1987–1992 Mazda Capella/626: 60 HP @ 4000 rpm, 12.3 kg·m (121 NM; 89 lb·ft) @ 2750 rpm (DIN, naturally aspirated EU version)

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 70 HP @ 4500 rpm on a raised 21.7:1 compression ratio, and has an exceptionally wide spread of torque throughout its range, peaking with 128 NM (94 lb·ft) at 3000 rpm.

-electrically controlled distributor type fuel injection pump
-electronically controlled EGR valve

RF-T DI 1998 (2.0 DiTD):
A direct-injection turbo version (102 HP) 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:
-89 HP @ 4000 rpm with maximum torque 220 NM (160 lb·ft) @ 1800 rpm
-99 HP @ 4000 rpm with maximum torque 220 NM (160 lb·ft) @ 1800–2200 rpm
-109 HP @ 4000 rpm with maximum torque 230 NM (170 lb·ft) @ 2000–2600 rpm
Engines were mounted in:
-Mazda 323 5D hatchback and 4D sedan since August 1998
-Mazda 323 5D hatchback and 4D sedan since January 2001
-Mazda 626 Capella since June 1998
-Mazda Premacy as DE 2.0L (DIREC-D) Euro 3
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 119 HP or 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 NM (230 lb·ft) at 2000 rpm), fuel efficiency and NOx emissions were improved by using:
-expansive vertical vortex combustion (EVVC), which combines a special piston surface design, with -ingenious fuel distribution, to produce a vertical swirl in the combustion chamber
-variable turbine geometry (VNT) turbocharger
Combined fuel economy is achieving 6.5 litres per 100 km and emission rating Euro Stage 3 (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):
-1st generation Mazda 6 Atenza (both versions) since June 2002
-2nd generation Mazda MPV (only High Power version) since June 2002
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 Ford Duratorq ZSD or PSA DW10 engines). Mazda applied several technologies to this MZR-CD engine to achieve Euro Stage 4:
-new variable geometry turbocharger has 14 percent less inertial moment and is more compact in -design (achieved, for instance, by a shorter distance between the exhaust gas inlet and the turbine shaft)
-Denso's 1800 bar second generation common rail system that, depending on driving conditions, uses multi-stage injection of up to nine times per cycle with six-hole injectors
-relatively low compression ratio of 16.7:1 improves power output and torque(???), while at the same time helping to lower combustion noise and emissions
-NOx emissions were reduced by lowering the engine's combustion temperature
-O2 sensor constantly measures residual oxygen in the exhaust gases and this information is sent to -32-bit powertrain control module (PCM), which continuously optimizes the air/fuel mix
There were two power versions of this engine: Standard Power 119 HP @ 3500 rpm and a maximum torque of 320 NM (240 lb·ft) @ 2000 rpm, High Power 141 HP @ 3500 rpm and a maximum torque of 360 NM (270 lb·ft) @ 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 4 standards. Engines were mounted in (in order of appearance):
-1st generation Mazda 6 Atenza (both versions) since July 2005
-Mazda 5 Premacy (both versions) since January 2006
-1st generation Mazda 3 Axela (only High Power version) since March 2007
RF 2007 (2.0 MZR-CD):
Slightly detuned 140 HP at 3500 rpm and 330 NM (240 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 mpg-imp; 42 mpg-US), less than its predecessor. Engine was mounted in (in order of appearance):
-2nd generation Mazda 6 Atenza since November 2007
