Prince is the codename for a family of

PSA Peugeot Citroën. It is a compact engine family of 1.4–1.6 L in displacement and includes most modern features such as gasoline direct injection and turbocharger
.

The

F20
and F21 114i, 116i and 118i . This was the first longitudinal engine mount option for Prince engine.

PSA started to use the Prince family in 2006 to replace a part of their TU family (the other part being replaced by the EB engine) — the Peugeot 207 being the first car to receive it.

The engine's components are produced by PSA at their Douvrin, France, facility, with MINI and BMW engine assembly at Hams Hall in Warwickshire, UK.[citation needed] The co-operation was announced on 23 July 2002 with the first engines produced in 2006. The Prince engine project is not related to the Prince Motor Company.

In late 2006, an extension of the cooperation between the two groups was announced,[2] promising new four-cylinder engines, without further details.

On 29 September 2010, it was announced by BMW[3][4] that the 1.6Turbo version of the Prince engine would be supplied from 2012 to Saab for use in forthcoming models, primarily the 9-3. However with the closure of SAAB supply never started.

At the Geneva Auto Show 2011, Saab unveiled their last concept vehicle: the Saab PhoeniX was fitted with the 1.6-litre, turbocharged BMW Prince engine with 147 kW (200 PS).[5][6]

On 25 June 2014 1.6-litre turbo Prince engine won its eighth consecutive

B38 engine which is replacing the Prince engine in the Mini and BMW lineups.[7][8]

Design

The Prince family shares its basic block dimensions with the previous

twin-scroll turbocharger will be used on the higher power versions.[9][10]

All Prince engines will share 84 mm (3.31 in) cylinder bore spacing, with 77 mm (3.03 in) bore. The 1.6 litre engine has a stroke of 85.8 mm (3.38 in). The engine features a two-piece "bedplate" aluminum crankcase for extra stiffness.[10]

1.4-litre EP3/EP3C (PSA)

The 1.4 L PSA EP3 and EP3C[11] is the smallest member of the Prince family with a stroke measuring 75 mm (2.95 in) and total capacity of 1,397 cc (1.4 L). Depending on application, power output varies from 66 to 70 kW (90 to 95 PS) while torque varies from 136 to 140 N⋅m (100 to 103 lb⋅ft).

Applications:

1.6-litre EP6/EP6C naturally aspirated (PSA)

The 1.6 L engine is used in the second-generation

MINI and various Peugeot 207
models. It has an 85.8 mm (3.38 in) stroke for a total of 1,598 cc (1.6 L) of displacement.

The

naturally aspirated variant (EP6, EP6C[11]) has conventional fuel injection and lost-foam cast cylinder heads. Its 11:1 compression ratio creates an output of 88 kW (120 PS) at 6000 rpm with a redline of 6500 rpm. Torque is 160 N⋅m (118 lb⋅ft) at 4250 rpm.[12]

Applications:

1.6-litre turbocharged (PSA)

The

turbocharged 1.6 L unit adds gasoline direct injection
and has special low-pressure die-cast heads. It has an 85.8 mm (3.38 in) stroke for a total of 1,598 cc (1.6 L) of displacement.

At first, there were two versions on offer – the THP150 and THP175, also known as the EP6DT and EP6DTS respectively within Peugeot. The first was later updated as EP6CDT and also as THP163, EP6CDTM.[11] There is also EP6CDT MD – with lowered compression ratio.

For the THP150 maximum torque is 240 N⋅m (177 lb⋅ft) at 1400 rpm. Power output is 110 kW (150 PS) at 5500 rpm.

Applications:

For the THP163 maximum torque is 240 N⋅m (177 lb⋅ft) at 1400 rpm. Power output is 121 kW (165 PS) at 5500 rpm.

Applications:

For the THP175 (EP6DTS, later EP6CDTS) maximum torque is 247 N⋅m (182 lb⋅ft) at 1600 rpm, remaining flat to 5000 rpm. Power output is 129 kW (175 PS) at 5500 rpm. An overboost function is available which temporarily increases torque to 260 N⋅m (192 lb⋅ft) between 1700 rpm and 4500 rpm in gears 3 to 5.

Applications:

In 2010 Peugeot released the 1.6 THP engine (EP6CDTX

twin-scroll turbocharger and Valvetronic variable valve lift. It was first introduced in the Peugeot RCZ sport compact for the 2010 model year
, where it generates 150 kW (204 PS).

Applications:

The 2012–2014 Mini John Cooper Works GP featured additional performance, with 160 kW (218 PS) at 6000 rpm and 280 N⋅m (207 lb⋅ft) of torque at 2000–5100 rpm from a larger turbo and engine internals.[13]

PSA has now released a new Euro 6 engine based on the THP in the following Engine codes:

BMW N13 version

The turbocharged 1.6 litre version used by BMW

BMW 2002
Turbo ceased production in 1974.

BMW sold the N13 alongside the larger displacement

Issues

There have been several cases of recalls and/or extended warranty due to failing HPFP (high pressure fuel pumps) in the Prince engine [17]

There was a service bulletin issued in 2013 due to failing timing chains and timing chain tensioner, both designed by BMW, in the Prince engine [18]

Production

The production of MINI version of 'Prince' family of engines is set to end by 2016, and be replaced by its very latest 3 and 4 cylinder Engine family –

BMW B38 and BMW B48.[19]

In 2015 it was announced, on the Hong Kong Stock exchange, that BMW had signed an IPR deal with XCE. They will make the N18 TVDI engine in China for use in various Brilliance Automotive vehicles (JV Partner of BMW in China) and also for other China OEM's.

PSA will continue to develop the higher power models of the engine family, with future production planned for China with its JV partners DONFENG (DPCA) and Changan (CAPSA).[20]
