Renault 1.3 TCe H5Ht Engine Specs, Problems, Reliability

Renault 1.3 TCe H5Ht Engine Specs, Problems, Reliability. The 1.3 TCe H5Ht is a 1.3-liter four-cylinder turbocharged and direct-injected engine co-developed by Renault-Nissan-Mitsubishi Alliance and their partner Mercedes-Benz (Daimler). The H5Ht engine debuted in 2017. Renault offers 4 versions with various levels of efficiency, which are branded as TCe115, TCe140, tce160, and tce150. Mercedes-Benz also produces and sells this 1.3 L turbo-four motor under the M282 codename. Nissan’s name for these engines is HR13DDT. While the Alliance utilizes their own industrial centers (Valladolid in Spain, Sunderland in the UK, and the Nissan Motor United Kingdom factory (NMUK)), the Mercedes-Benz M282 engine is made in Germany at Daimler’s factory in Kolleda. Let’s take a thorough look at the 1.3 TCe H5Ht engine style, its common problems, reliability, and longevity.

Renault 1.3 TCe H5Ht Engine Specs

The 1.3 L TCe is an all-aluminum engine. It has an aluminum open-deck engine block with plasma-coated cylinder walls. Bore Spray Covering is really tough steel sprayed on the surface of the walls using a plasma torch. This technique improves heat conductivity, decreases unrestrained detonations, and gives significant savings in weight. The engine is equipped with a created crankshaft and lightweight aluminum pistons with an unique graphite finishing on skirts for optimized friction and use resistance. By the way, pistons are furthermore cooled with oil by oil jets. To even more enhance engine effectiveness, the H5Ht was equipped with a variable displacement oil pump.

While the cylinder block, engine, and crankshaft devices were developed by Renault, the cylinder head style is the result of Mercedes’s cooperation. The German engineers ended up with a very unusual triangular “Delta” cylinder head with four valves per cylinder and centrally located direct injectors. The delta shape makes it slightly higher, but much narrower and lighter than conventional rectangular shape design. The cylinder head comes with 2 chain-driven camshafts (consumption and exhaust). The 1.3 TCe functions twin independent variable camshaft timing for consumption and exhaust. The engine utilizes a single row timing chain, which has an engine’s life time warranty.

The intake and exhaust valves are actuated by cameras through finger follower-type rocker arms. The valvetrain consists of hydraulic guidance supports for rocker arms to make sure continuous valve clearance. Water-cooled exhaust ports inside the cylinder head type part of the exhaust manifold. In this case, the exhaust manifold is partially integrated into the design. Such a technical trick offers more efficient combustion keeping the engine temperature level in optimal variety by cooling exhaust gases, particularly at low engine speeds and/or in cold weather.

The crucial features responsible for the fantastic efficiency and performance of the 1.3 L TCe engine are direct fuel injection and turbocharger. The direct fuel injection system is fed by a high-pressure injection pump with a maximum output of 250 bar. A high-pressure pump provides fuel through a common rail to 6-hole injectors that spray straight into the combustion chambers. Compressed consumption air is provided by a fixed geometry turbocharger with a completely electronically controlled, motor-driven wastegate (e-wastegate). After turbocharger, exhaust gases go through a catalytic converter as basic and particulate filter on engines with WLTP evidence (Euro 6c).

1.3 TCe H5Ht Engine Problems and Reliability

Well, is the Renault 1.3 TCe a excellent and dependable engine? The manufacturer declares that this new 1.3-liter turbo engine, after more than 40,000 hours of simulations and tests, meets all the quality standards of the Renault-Nissan-Mitsubishi Alliance and Daimler. And it looks like the engineers at Mercedes and Renault managed to develop a genuinely reliable little turbo engine. No serious style defects are found on the 1.3 TCe motor. Obviously, you can find subjects about some problems that pop up on the Internet, but, in fact, the prevalence of such problems is exaggerated. Let’s highlight a few of the most noted issues and problems, even if it’s not fair to call them common problems that affect a lots of engines.

There are a few of the most common Renault 1.3 TCe engine problems:

  • Carbon build-up
  • Excessive oil usage

All engines with direct fuel injection basically experience carbon accumulation on the consumption valves and ports. With a port injection, gasoline is injected into the consumption ports and cleans a by-product of oil and fuel burn. Since they spray fuel directly into combustions, direct-injected engines do not have this side effect of the existence of air and fuel mixture inside intake ports. Over time, a build-up of gunk or sludge forms on the intake valves and walls inside intake ports. In some unusual cases, the carbon accumulation can have visible performance ramifications since it restricts the air flow so that the engine does not get enough oxygen to burn fuel effectively. Don’t stress too much, many of the engines will likely live their whole lives with excess carbon deposits.

Compared to its predecessor, the 1.2 TCe, the brand-new 1.3-liter engine does not have such an apparent excessive oil consumption issue. Some owners reported on the Web about progressive oil usage starting currently from the first thousand miles. More than likely, the reason for such cases is assembly engine obstructs with cylinder walls, pistons, or oil rings that do not fulfill specifications. Some engines likewise experience high oil intake as they age. Constantly keep in mind, this type of small-displacement turbo engines are susceptible to consume oil under heavy loads more than most of the naturally aspirated engines with a comparable level of efficiency. This is why 1.3 L TCe needs top-notch artificial motor oil that can withstand greater temperatures and pressure.

That stated, the Renault 1.3 TCe is a quite reliable engine. There are already plenty of examples of the 1.3 TCe H5Ht engine holding up to 100,000+ miles (150,000+ km) without any major issues. Nevertheless, keep your engine well and, we believe this amazing engine will last more than 160,000 miles (250,000 km).
