The L-series engine commenced production on 28 November 1994 and was the first Rover designed and manufactured direct injection Diesel for use in Rover Cars applications and derived from the established Rover MDi / Perkins Prima engine (Perkins BA / Perkins 4.20 naturally aspirated and Perkins BB / Perkins T4.20 turbocharged) used in the Austin Montego, Austin Maestro, and Leyland Sherpa van sold by 'Freight Rover' in the '80s, later by LDV.
The engine started production in low volume at Longbridge for Rover 600 only at first with later higher volume production at Solihull for all other applications.
A development of the L-series engine (G series) featuring a modern common railfuel injection system was underway when MG-Rover ceased production, but the company's closure prevented it from being fully developed and released.
The last and most recent engine is intercooled and also has an electronically controlled injection system which is slightly more advanced and produces more torque but the same power output as earlier intercooled models. This is the version that is used in the Rover 25, Rover 45, MG ZR, and MG ZS.
All versions use Bosch fuel-injection equipment of various designs. An unusual feature is that the injector pump is driven by a toothed belt from the 'rear' end of the overhead camshaft, itself driven at the 'front' end by another toothed belt connected to the crankshaft.
The engine is extremely environmentally friendly in terms of its emissions.[according to whom?] It is quiet in operation owing to its two-stage fuel injection & ECU controlling fuel for most models and timing for them all. [according to whom?] The engine currently satisfies ECD III derogated Diesel emissions legislation when installed with an appropriate specified oxidation catalyst.
Sensors around the engine constantly give feedback to the ECU regarding injection timing, engine speed, load, fuel and coolant temperature, boost pressure etc. to ensure that optimum running conditions are maintained.
The Land Rover Td5 engine, a 2.5-litre, 5-cylinderturbodiesel used in the Discovery and the Defender had the same bore/stroke dimensions as the L series and used the same pistons, connecting rods and crankshaft dimensions. However, the Td5 was not simply a 5-cylinder L series. It used Lucaselectronic unit injection, instead of the L series' direct-injection system, as well as a through-flow cylinder head and a very different ancillary equipment layout. The Td5 had been developed by the Rover Group under the codename 'Project Storm', which was originally to develop a replacement range of turbodiesels to replace the L series, with 4-, 5-, and 6-cylinder engines of 2, 2.5, and 3 litres respectively. When the Rover Group was taken over by BMW, they brought their own range of diesels which rendered the 2-litre and 3-litre Storm engines unnecessary. Only the Td5 entered production as this was the only diesel engine of BMW or Rover that would fit lengthwise in the Discovery and Defender with sufficient power output and had the then up-to-date direct-injection system.

The Austin Maestro is a five-door hatchback small family car that was produced from November 1982 to 1986 by British Leyland, and from 1986 until December 1994 by Rover Group, as a replacement for the Austin Maxi and Austin Allegro, with the van version replacing the corresponding van derivative of the Morris Ital. The car was produced at Morris' former Oxford plant, also known as Cowley, with 605,000 units sold. Today, the redeveloped factory builds the BMW Mini. An MG-branded performance version was sold as the MG Maestro from 1983 until 1991.
The Ford Duratorq engine, commonly referred to as Duratorq, is the marketing name of a range of Ford diesel engines introduced in 2000-2020. The larger capacity 5-cylinder units use the Power Stroke branding when installed in North American-market vehicles. The first design, codenamed "Puma" during its development, replaced the older Endura-D unit which had been around since 1984. Commercial versions of the Puma unit replaced Ford's older "2.5Di" type unit used in the Transit, and many other manufacturers' vehicles - most notably the London Taxi and in the Land Rover Defender. Other unrelated units in this range have been developed by Ford and PSA. The TDCi Duratorq engines are available in vehicles from Ford, Jaguar, Land Rover, Volvo and Mazda. A new EcoBlue diesel engine range, originally codenamed "Panther" and planned to be available in 2.0- and 1.5-litre variants, will progressively replace the Duratorq engines from 2016.
The Austin Montego is a British family car that was produced by British Leyland from 1984 until 1988, and then by Rover Group from 1988 until 1995. The Montego was the replacement for both the rear-wheel drive Morris Ital and the front-wheel drive Austin Ambassador ranges to give British Leyland an all-new competitor for the Ford Sierra and Vauxhall Cavalier.

The Volkswagen LT is the largest light commercial panel van produced by Volkswagen from 1975 to 2006, before being replaced by the Crafter. Two generations were produced.
The Land Rover Defender is a series of British off-road cars and pickup trucks. They consistently have four-wheel drive, and were developed in the 1980s from the original Land Rover series which was launched at the Amsterdam Motor Show in April 1948. Following the 1989 introduction of the Land Rover Discovery, the term 'Land Rover' became the name of a broader marque, and thus no longer worked as the name of a specific model; thus in 1990 Land Rover renamed the 90 and 110 as Defender 90 and Defender 110 respectively. The 127 became the Defender 130.
Mazda has a long history of building its own diesel engines, with the exception of a few units that were built under license.
The Rover 400 Series, and later the Rover 45, are a series of small family cars that were produced by the British manufacturer Rover from 1990 to 2005. The cars were co-developed as part of Rover's collaboration with Honda. The first-generation 400 was based on the Honda Concerto, and the Mark II 400 was based on the Honda Domani/Civic.
The Austin Motor Company A-series is a British small straight-4 automobile engine. Launched in 1951 with the Austin A30, production lasted until 2000 in the Mini. It used a cast-iron block and cylinder head, and a steel crankshaft with three main bearings. The camshaft ran in the cylinder block, driven by a single-row chain for most applications, and with tappets sliding in the block, accessible through pressed steel side covers for most applications, and with overhead valves operated through rockers. The cylinder blocks are not interchangeable between versions intended for conventional end-on mounted gearboxes and the 'in-sump' transaxle used on British Motor Corporation/British Leyland front wheel drive models such as the Mini. The cylinder head for the overhead-valve version of the A-series engine was designed by Harry Weslake – a cylinder head specialist famed for his involvement in SS (Jaguar) engines and several Formula One-title winning engines. Although a "clean sheet" design, the A-series owed much to established Austin engine design practise, resembling in general design and overall appearance a scaled-down version of the 1200cc overhead-valve engine first seen in the Austin A40 Devon which would form the basis of the later B-series engine.
The AJD is a family of V6 and V8 turbodiesel engines with a clean-sheet architecture and variable valve timing developed by Ford of Europe for its then-subsidiaries Jaguar and Land Rover, as well as for its partner PSA Group working under the Gemini joint development and production agreement. It is called the AJD-V6 in the Jaguar and Land Rover vehicles and the DT17/DT20 by Citroën and Peugeot. The engines share the same bore/stroke ratio, with the V6 version displacing 2.7 L (2,720 cc) and the V8 version displacing 3.6 L (3,630 cc). The V6 and the V8 were launched in 2004 and 2006 respectively. The V6 engine meets the Euro IV emissions standards. A DT20 3.0 L (2,993 cc) was added in 2009 and is based on the DT17 2.7 L (2,720 cc). The V6 is used across many vehicles, from the Citroën C5 and C6, to the Land Rover Discovery, Range Rover, multiple cars in the Jaguar range, and also the Ford Territory and next gen Ford Ranger.
The Volvo B21 is a slanted straight-four engine first used in the Volvo 200 series, meant to replace the B20. The B21 and all derived engines are often referred to as red block engines for the red paint applied to the block. The primary differences when compared to the B20 was the switch to a SOHC in place of the older pushrod configuration, and an aluminum crossflow cylinder head versus the iron head of the B20.
The BL O-series engine is an automobile straight-four engine family that was produced by the Austin-Morris division of British Leyland (BL) as a development of the BMC B-series engine family.
F Renault engine is an automotive internal combustion engine, four-stroke, inline-four engine bored directly into the iron block, water cooled, with overhead camshaft driven by a timing belt, and with an aluminum cylinder head, developed and produced by Renault in the early '80s, making its appearance on the Renault 9 and 11. This engine is available in petrol and diesel versions, with 8 or 16 valves.
The S series is a straight-4 SOHC internal combustion engine developed by the Austin Rover Group, and produced from 1984 until 1993. The engine was used in the Austin Montego, Mark 1 Rover 200-series and the MG Maestro. The engine was used in the Austin Maestro from 1985 onwards.
