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.
