- Rover L-Series engine
engineis an automotive diesel enginebuilt by Powertrain Ltd, a sister company of MG Rover.
The L-Series engine commenced production in January 1995 and was the first in-house designed and manufactured "direct injection" diesel for use in Rover Cars applications and derived from the established Perkins MDi Prima engine used in the
Austin Montego, Austin Maestro, and LDV Sherpa van. The L series is extremely versatile and has been fitted in the Land Rover Freelander, Rover 200 Mk3, Rover 400 Mk2, Rover 600, and European versions of the Honda Accordand Honda Civic. A development of the L series engine (The G-Series) featuring a modern common-rail fuel injection system was underway when MG-Rover ceased production, but the company's closure prevented it from being fully developed and released.
There are several forms of this engine.
The first is a non intercooled, mechanically controlled fuel injection system. This version is available in
Rover 200and Rover 400models and the model designation ends in "D", i.e. SD, SLD etc., etc.
The second is
intercooledand has an electronically controlled fuel injection system. This version is available in Rover 200, Rover 400and Rover 600models. The model designation ends in "Di", i.e. SDi, SLDi etc., etc.
The last and most recent engine is
intercooledand 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.
The engine is extremely environmentally friendly in terms of its emissions. It is quiet in operation owing to its two stage fuel injection & ECU controlling fuel for most models and timing for them all. The engine currently satisfies ECD IIl derogated Diesel emissions legislation when installed with an appropriate specified oxidation catalyst.
around the engine consistently 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 basic engine is a conventional
4 cylinderwith 2 valves per cylinder operated by a single overhead camshaftand hydraulic tappets.
The block is made of
cast ironwith aluminum alloy head and sump. An Allied SignalGT15 turbo chargersupplies boosted air. A fully modulated, either air or water cooled exhaust gas recirculation(EGR) system is incorporated into the intake/ exhaust system.
All accessories (PAS,
aircon, water pump, vacuum pump, alternator) are all driven off a single poly-vee-belt drive with autotensioner. Camshaftand injection pumpdrives are via two multi-toothed belts with either automatic or manual tensioners.
Land RoverTd5 engine, a 2.5-litre, 5-cylinder turbodieselused 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 Lucas Electronic 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 Groupunder 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.
The L-series engine has been availbable in 3 specifications.
