Mazda has a long history of building its own diesel engines, with the exception of a few units that were built under license.
The Perkins 200 series engines (GA/GB/GC in internal parlance) were manufactured by licensee Toyo Kogo (Mazda) for use in automotive and other applications. Perkins 4.135, 4.154, and 4.182 manufactured replacement engine parts are used interchangeably in the Mazda S2, XA, and HA engines, respectively.
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.
Applications:
The emission improved version used in the Mazda 323 from mid-1997 adopted 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.
Further engine features:
Engines were mounted in:
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:
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 mpg‑imp; 36 mpg‑US) 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):
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):
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 mpg‑imp; 42 mpg‑US), less than its predecessor. Engine was mounted in (in order of appearance):
A diesel variation of the 2.2 L (2,184 cc) F2 which shares its 86 mm × 94 mm (3.39 in × 3.70 in) bore and stroke. Displacement: 2,184 cc (2.2 L; 133.3 cu in) Power net:(Black Top) 51.5 kW (70 PS; 69 hp) (JIS net) at 4050 rpm Torque: 142 N⋅m (105 lb⋅ft) - at 2500 rpm Power net:(Silver Top) 58.1 kW (79 PS; 78 hp) (JIS net) at 4050 rpm Torque: 171 N⋅m (126 lb⋅ft) - at 2500 rpm
Applications:
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:

Engine features:
The Ford Duratorq engine, commonly referred to as Duratorq, is the marketing name of a range of Ford diesel engines first introduced in 2000 for the Ford Mondeo range of cars. The larger capacity 5-cylinder units use the Power Stroke branding when installed in North American-market vehicles.
The GM High Feature engine is a family of modern DOHC V6 engines produced by General Motors. The series was introduced in 2004 with the Cadillac CTS and the Holden Commodore (VZ).
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.
The Mitsubishi Astron or 4G5/4D5 engine, is a series of straight-four internal combustion engines first built by Mitsubishi Motors in 1972. Engine displacement ranged from 1.8 to 2.6 litres, making it one of the largest four-cylinder engines of its time.
Multijet is Stellantis's term for its current common rail direct injection turbodiesel engine range. Most of the Fiat, Alfa Romeo, and Lancia range, as well as certain Chrysler, RAM Trucks, Jeep, and Maserati vehicles, are equipped with Multijet engines. Ownership of some Fiat Multijet designs is shared with General Motors as part of a settlement of the failed merger between the two auto conglomerates. The GM Powertrain Torino group in Turin, Italy, manages its interest in these engines. Some PSA Peugeot Citroën diesel engines are also rebadged JTD units, and vice versa. Fiat's common-rail diesel engine is also known as JTD, an initialism of Jet Turbo Diesel.
The Suzuki G engine is a series of three- and four-cylinder internal combustion engines manufactured by Suzuki Motor Corporation for various automobiles, primarily based on the GM M platform, as well as many small trucks such as the Suzuki Samurai and Suzuki Vitara and their derivatives.
The Honda F-Series engine was considered Honda's "big block" SOHC inline four, though lower production DOHC versions of the F-series were built. It features a solid iron or aluminum open deck cast iron sleeved block and aluminum/magnesium cylinder head.
The Toyota KR engine family is a straight-3 piston engine, designed by Daihatsu, a subsidiary of Toyota. The 1KR series uses aluminium engine blocks and chain driven DOHC cylinder heads. It uses multi-point fuel injection, and has 4 valves per cylinder. Some versions have VVT-i variable valve timing. The engine is exceptionally light: 69 kg (152 lb) with all ancillaries. This is due to the nature of the applications and weight of city cars.
The Ford Duratec V6, is an aluminum DOHC V6 engine with a 60° bank angle introduced in 1993 with the Ford Mondeo. The primary engineering input came from Porsche, who was developing a similar V6 before selling the engineering to Ford, and Cosworth, who helped with cylinder head manufacturing. The Jaguar AJ-V6 engine is similar but adds variable valve timing.
The Honda R engine is an inline-four engine launched in 2006 for the Honda Civic (non-Si). It is fuel injected, has an aluminum-alloy cylinder block and cylinder head, is a SOHC 16-valve design and utilizes Honda's i-VTEC system. The R series engine has a compression ratio of 10.5:1, features a "drive by wire" throttle system which is computer controlled to reduce pumping losses and create a smooth torque curve.
The Toyota KD engine series is a diesel engine produced by Toyota which appeared in 2000.
The N series is Honda's first automotive diesel engine, an inline-four for medium-sized vehicles. It uses common rail direct injection, which Honda brands as i-CTDi. The most notable feature is the aluminium block, which uses proprietary technology in the manufacturing process to provide light weight and high rigidity. Roller chains drive two overhead camshafts. A variable-geometry turbocharger and intercooler are used.
The Toyota ND is an inline-four diesel engine used for Toyota models in various markets including Japanese, Indian and European ones.
The Toyota AD engine family is a series of 16 valve DOHC inline-4 turbo diesel engines with electronic common rail direct injection using an aluminium cylinder head and an aluminium cylinder block with cast iron liners derived from the petrol Toyota AZ engine. The AD engine is offered in 2.0 and 2.2 liter versions. These engines are produced mainly for Europe, but few are exported to other areas such as India or New Zealand.
The Hyundai U engine is a series of three or four-cylinder diesel engines made for automotive applications by the Hyundai Kia Automotive Group. The U series of engines includes the smallest automotive diesel engines produced by Hyundai.
The Mazda L-series is a mid-sized inline 4-cylinder gasoline piston engine designed by Mazda as part of their MZR family, ranging in displacement from 1.8 to 2.5 liters. Introduced in 2001, it is the evolution of the cast-iron block F-engine. The L-series is used by Ford as their 1.8L to 2.5L Duratec world engine.
The Toyota NR engine family is a series of small inline-four piston engines designed and manufactured by Toyota, with capacities between 1.2 and 1.5 litres.
Skyactiv is a brand name for a series of automobile technologies developed by Mazda that increase fuel efficiency and engine output. The initial announcement of the Skyactiv technologies included new engines, transmissions, body, and chassis, which appeared in Mazda products from 2011 onwards.
The Suzuki K engine family is a series of automobile engines from Suzuki, introduced in 1994. Displacements range from 0.7 L to 1.5 L. All engines have aluminium cylinder blocks with three or four cylinders in-line. Cylinder heads have two overhead camshafts, driven by chain, and four valves per cylinder. Fuel is gasoline/petrol, metered by multipoint fuel injection or direct injection. Some variants are turbocharged.
