context_page_description: The MR is a family of straight-four all-aluminium automobile engines with variable valve timing co-developed by Renault and Nissan. Renault calls it the M engine. Other noteworthy features of this engine family include acoustically equal runner lengths and a tumble control valve for the intake manifold, a "silent" timing chain, mirror finished crankshaft and camshaft journals, and offset cylinder placement in an attempt for increased efficiency.
  The MR engine family features 'under stress' manufacture, meaning while the block is being bored, a torque plate puts the block under stress. The block becomes temporarily distorted until the head is torqued onto it, at which point the block is pulled into the correct shape.
context_section_description: The M9R is available in the 150 PS (110 kW; 148 hp) tune in Nissan Qashqai, Nissan X-Trail, Renault Mégane, Renault Koleos and Renault Laguna models. In this trim the engine achieves maximum power at 4000 rpm and maximum torque of 340 N⋅m (251 lb⋅ft) at 2000 rpm. A 175 PS (129 kW; 173 hp) form with particulate filter is available in Renault Laguna and Nissan X-Trail models. A 180 PS (132 kW; 178 hp) variant is also available on the Laguna GT. In both engines maximum power is achieved at 3750 rpm and maximum torque is available from 1750 rpm.
  In order to reduce vibrations, balance shafts are included in some versions of the engine.
  The 2.0 dCi engine in all its versions complies with the Euro 4 and 5 standards for exhaust emissions. The 150 PS (110 kW; 148 hp) New Mégane and New Laguna respectively emitted 144 g (5.1 oz)/km and 154 g (5.4 oz)/km of CO₂ and the 129 kW (175 PS; 173 hp) version of New Laguna 2.0 dCi emits 159 g (5.6 oz)/km of CO₂; they all comply with the Euro 5 standards for exhaust emissions.
  In 2011 the 96 and 110 kW (131 and 150 PS; 129 and 148 hp) M9R engines has been updated with an optional package to lower exhaust emissions (Euro5) and fuel consumption. These engines are tagged "2.0 Energy dCi 130" resp. "2.0 Energy dCi 150", typically maximum power is available at 3750 rpm and maximum torque at a minimum of 1750 rpm. The package comprises:
  Stop & Start
  Active thermal management
  Smart electrical management
  Variable capacity oil pump
  The CO₂ values were thus reduced to 118 g (4.2 oz)/km for the Laguna both the 2.0 Energy dCi 130 and 2.0 Energy dCi 150.
  The engine is fitted to the following vehicles:
  2007–2011 Nissan Qashqai
  2007–2012 Nissan X-Trail
  2005–2015 Renault Laguna
  2006–2015 Renault Mégane
  2007–present Renault Koleos
  2006–2014 Renault Espace
  2007–2010 Renault Vel Satis
  2015 Nissan Teana
  2006-2014 Vauxhall Vivaro Renault Trafic Nissan Primastar
  2010–present Renault Latitude
  2015–present Renault Espace V
