Isuzu P9X V6 DMAX engine

The Isuzu V6 DMAX engine is a 3 litre four-stroke diesel internal combustion automotive engine with six V-cylinders used by Renault ,Saab and Opel.

History

This P9X engine is mounted on high-end models of various brands under engine names D308L ,Y30DT ,Z30DT.This uses high-pressure common rail direct injection with four valve per cylinder, cylinder heads engine bored directly into the cast iron block, open at 65 °, water cooled, with a 4-bearing crankshaft, with 4 shafts overhead cam, driven by a belt distribution notched with two yokes aluminum 24 OHV. This engine is produced by the Japanese manufacturer Isuzu , but the design rights for this engine are now owned by General Motors.

The characteristics of this engine are:

• 6-cylinder V-shaped architecture
• Displacement 2958  cm ³
• Bore and stroke 87.5 × 82 mm
• Square motor
• 65 ° angle between rows of cylinders
• Direct injection with common rail direct injection technology
• Supercharged by variable geometry turbocharger and intercooler
• Compression ratio equal to 18.5: 1

The DMAX V6 engine initially developed an output of 177 hp at 4,400  rpm , with torque of 350 Nm at 1,800  rpm . Subsequently, from 2006, this engine was slightly revised, developing 180 hp of maximum power at 4,000  rpm and 400 Nm of torque at 1,800  rpm with  turbocharger and intercooler . This engine was fitted to models of different brands, but somehow linked together. These models are:

• Renault Vel Satis
• Renault Espace IV
• Saab 9-5
• Opel Vauxhall Vectra
• Opel Vauxhall Signum

The link between these brands is quite simply that Opel belonged to General Motors at the time , Saab also belonged to this American giant, as for Renault, they manufacture utility vehicles for Opel. The Fiat group was also interested in this V6 Diesel project, for the Lancia Thesis , but the project fell through.

At Renault, it bears the name: P9X , at Saab: 6de1 and at Opel: Y30DT .

Renault R9M engine

The R9M Renault engine is a 1.6L automotive internal combustion Turbo diesel four-stroke, with 4 cylinders in line bored directly in the block, water-cooled, with a 5-step crankshaft, 2 camshafts head driven by a chain distribution, with a cylinder head in aluminium, valve head, manufactured by Renault, making its appearance on the Scenic III.

History

These 4 cylinders is completely new designed specifically for diesel applications. Renault started from a blank page to design this block. Engineer Philippe Coblence is head of the R engine design office, which looked after F1 engines at the start of the 2000s. Three meeting points between F1 technology and this new R engine: square engine, circulation transverse water, reduction of internal friction.

Appeared in 2011 on the Scénic III, this first 1.6 dCi version of the R9M type is equipped with technologies usually reserved for more high-end engines, it is intended to replace the “F engine” which appeared in the early 1980s on the Renault 9 and Renault 11, therefore the 1.6 dCi type R9M replaces the 1.9 dCi type F9Q of equal power, with increased torque or 130 and reduced consumption and emissions along with a more powerful 160 twin-turbocharged version. 

With a smaller displacement, this engine consumes less than the one it is intended to replace, while maintaining performance thanks to improved supercharging. This block and its mobile coupling have been designed to withstand the strong constraints inherent in diesel engines.

The pistons in this engine feature U-shaped segments, a technology inspired by F1. It is equipped with a variable-flow oil pump which therefore uses less energy because the pumped oil is entirely used to lubricate the engine and not delivered. Its cooling circuit is in 2 parts, when cold the water does not circulate around the cylinders in order to accelerate the warm-up of the engine.

Renault-Nissan H engine

The H engine at Renault, is an internal combustion automobile four-stroke gasoline engine with 3 or 4 cylinders since 2004

History

The H engine also known as the HR engine at Nissan has in line bored directly into the aluminium block, cooled by water, with a crankshaft 4 on bearings versions cylinders 3 and 5 levels in the 4-cylinder, 2 camshafts head driven by a timing chain, with a cylinder head made of aluminium, OHV, manufactured by Renault and Nissan, making its appearance on the Mégane III. In 2009, the H engine appeared on the Mégane III, in a 4-cylinder version of the H4Jt type. (1.4 TCe 130). This new engine is intended to replace the K engine which appeared on the Mégane I in 1995, which was a final evolution of the legendary Cléon-Fonte engine.

At the end of 2012, when the Clio IV was launched, the 3-cylinder version of the H4Bt type (0.9 TCe 90) made its appearance, with the aim of gradually replacing the D engine manufactured by the French mechanical company and which had appeared on the Twingo I and the Clio I phase 3, in 1996. This engine was also fitted to Smart vehicles in a 0.9 turbo and 1.0 atom version. Renault is also offering 1.5L petrol in India from 2017.Also from 2017 the 1330 cm ³ displacement (H5Ht) arrives in the Renault range, including the new Scénic 4. Called to replace the old H5Ft, it offers power ratings from 115 to 160hp. It was designed in collaboration with Daimler.

Engine failures for the 1.2l H5Ft and HRA2DDT. In march 2016 on confidential manufacturer technical notes which noted problems of excess oil consumption on Renault 1.2 TCe engines from 2012 until, 2016 also 6confirming that Nissan and its 1.2 DIG-T engine was also affected .The manufacturers have since developed a reprogramming of the engine control unit and have also improved the chrome coating of the piston rings on the new 1.2 TCe and DIG-T models, without however recalling engines previously produced and potentially affected by however, this defect can cause premature engine wear .But also highlights a hidden defect in the H5Ft produced between 2012 and 2016. A pressure defect in the intake duct would prevent the natural filling of the engine. which would consequently lead to excess oil consumption and premature wear. The warning signs for this failure which appears apparently from 60,000 km and would be amplified if the engine is mainly used in city driving. Later reveal another cause of failure mentioned in Renault's internal documents: a fault in the knock sensor causing the appearance of a self-ignition phenomenon (known as "LSPI": Low Speed ​​Pre-Ignition), which would cause the gradual degradation of these engines.

Models with Defects

• Renault (1.2 TCe 100 *, 115, 120 and 130 hp)
• Captur, Clio IV, Kadjar, Kangoo II, Megane III, Scénic and Grand Scénic III
• Dacia (1.2 TCe 115 and 125 hp)
• Duster, Dokker and Lodgy
• Mercedes-Benz (1.2 115 hp)
• Citan
• Nissan (1.2 DIG-T 115 hp)
• Qashqai II, Pulsar and Juke

Also following the DieselGate scandal, the Vehicle Market Surveillance Unit in Great Britain went further than the Royal Commission in France in 2016; they also decided to test gasoline vehicles in real driving conditions in order to check whether they respected the NOx emission thresholds for which they were approved. The result was overwhelming in real driving conditions, the Nissan Qashqai tested in this way had emissions nearly 10 times higher than in NEDC tests. The report also states that because the Nissan Qashqai did not have a sequence to activate "dynamic" mode, a vehicle-specific wiring harness was required in order to drive the vehicle on the NEDC test dynamometer chassis.

PSA ESL L7X V6 engine (1997 to 2010)

The Petrol 2.9 L (2,946 cc) PSA V6 60° V-angle engine also known under the code "engine ES" ES9 PSA and "L" L7X engine is used by among others Citroën, Peugeot and Renault from the late 90s to the early 10s.

History

Introduced in 1997 with the Peugeot 406 Coupé, its design was most modern for the time. It provides a power of 140 kW (190 hp) for 2 946 cm ³ of displacement. It is also equipped with a catalyst, which has become essential for the respect of European emission standards.

 The Petrol PSA V6 ESL engine also known under the code "engine ES" PSA and "motor L7X" is an automobile internal combustion gasoline four-stroke, six-cylinder V with dry cast iron liners in the aluminium block, cooled by water, with 4 camshafts head, driven by a belt distribution notched with two yokes constructed entirely in aluminium, and DOHC 24-valve type. 

ESL is the acronym for ES (PSA) and L (the Renault). This replaced the old “V6 PRV engine “used in Peugeot, Renault and Volvo. It is the result of a collaboration between the two French car manufacturers PSA and Renault, and its costs were shared. For Renault, it is part of a motor investment campaign of about 2 billion Euros. The "V6 ESL engine" is machined and assembled at Douvrin, in the plant of the Société Française de Mécanique created in 1969 by Renault and Peugeot, each of which owned 50% of the company.

It was later updated in 2000 for the release of the Peugeot 607 and the Citroën C5, and continued on the Peugeot 406 and 406 Coupé with help from Porsche introducing variable valve timing its power is increased to 155 kW (211 hp EEC) as the ES9 J4S version.

Renault with its engine SOLUTION pushes the power even more for its Clio V6, its power is raised to 230hp (169 kW). For its Clio V6 phase 2, the injection ramp is split and the injectors are 50% bigger. The preparation, once again at Porsche Engineering, allows the engine to develop 255 hp (188 kW), making it one of the best V6 of the time.
The Renault-Nissan Alliance led Renault to use the " V6 VQ “Nissan of 3.5 litres so this engine is no longer available in any form since it was removed from the Citroën C5 II in January 2, 2010. It had been used up to in 2009 on the Peugeot 607, 407 Coupé and the Citroën C6.
