R9M engine

The Energy dCi 130 engine is an engine that was developed by the consolidated work between Renault, Nissan, and Mercedes, on a 1.6 dCi version in 2011 as a result of the need for improvements on the predecessor 1.9 dCi engine.

With a variable geometry turbocharger or a high-pressure EGR valve, this engine, known as ‘R9M’, rapidly found its way into a wide range of applications, becoming the new popular engine thanks to its 130 HP and innovative technology.

Later, and after its good performance, were launched on new versions as 160 and 145HP.

The main improvement of this engine versus its predecessor, the 1.9 Dci, was the reduction on consumption and emissions.

Proof of this are the following examples:

• On the Renault Scenic the engine consumption is 4,5 l/100km whereas its predecessor on the 1.9 DCI was 5.4L.
• Regarding CO₂ emissions, the R9M data is 117g/km de CO₂ compared to 149g/km for 1.9 Dci.

How they manage to do so?

These improvements in fuel economy and emissions savings over other engines are achieved through four key factors in the configuration and design of this engine:

1. The concept of variable vane oil pump able to adjust the oil flow and pressure according to the engine needs.
2. Variable spiral air inlet admission that helps the engine to optimize the air/fuel mixture.
3. Optimized thermal management with an internal valve capable of managing the coolant through the engine just when is needed.
4. An EGR exhaust gas recirculation system. A low-pressure EGR valve directs exhaust gases through a filter before entering them back into the intake.

What can go wrong then? R9M engine issues

Previous Renault engines are known to have struggled on timing belt system, putting too much stress on the tensioner and even on the water pump bearing. The idea to use a timing chain kit was the best option, but this design presents a challenge.

The inlet an exhaust cams are connected through a cog gear mechanism, the teeth are no helicoidal as we can see in most recent Mercedes engines. Through the usage and on some occasions an incorrect maintenance, a clearance is generated between the gears.

This clearance generated noise and since the cam timing chain sprocket is mounted directly on top of one of the gears, the vibrations are transmitted to the timing chain kit mechanism. As result a premature wear between the sprocket and chain happens.

What are the trends in aftermarket spare parts?

Aftermarket car and truck parts did not have the same reputation as they had now a decade ago relative to original parts, but an industry-wide focus on quality has begun to change that, reversing that trend, for high quality products at competitive prices. Sales of vehicle components in general, and aftermarket spare parts in particular, have increased dramatically as individuals seek to save money on repairs. maintaining the quality of the vehicle component and the workmanship.

Another major paradigm shift is that the car parts business will sell over 7.4 billion online this year, with eCommerce auto parts sales expected to rise at a rate of 15% over the next several years, exceeding brick-and-mortar retailers.

Most demanded aftermarket truck parts

In this article, we will see which are the most demanded spare parts for trucks on the aftermarket and the importance of these in your vehicle:

1. Transmission and clutch
2. Tires and breke
3. Water pump

Transmission and clutch parts 

When the clutch pedal is depressed, the clutch works as a mechanical link between the engine and gearbox, quickly disconnecting or separating the engine from the transmission system, and therefore the drive wheels, allowing the driver to smoothly change gears. The manual transmission system is made up of various components. Each one is necessary for the gearing changing and clutch releasing functions to work. You won’t be able to drive smoothly if one of these components fails. These are extremely important and popular aftermarket vehicle parts.

Tires and brake parts

The most important safety features of a vehicle are the brakes and tires. According to surveys, they are the most common vehicle problem cited in highway accidents, second only to tires. Any condition necessitates a good set of tires, which work hand in hand with a suspension kit. To fill the gaps created by lifting your truck, you’ll need larger tires. If you lower your truck, you’ll need a tire with a lower profile to avoid the truck hitting the tires. To be safe, even if your truck has no extra modifications, make sure you have strong all-around traction.

Truck water pump

The water pump makes sure that enough coolant liquid flows around the cooling system and engine to remove enough heat and keep the engine from overheating. Because a good water pump circulates coolant to cool the engine, a defective water pump will allow engine heat to build up to dangerous levels. The most popular aftermarket truck part is a truck water pump, which is required for engine health and safety.

However, the growing life expectancy of vehicles and its resulting increase in miles travelled makes chain-driven timing systems subject to wear. 

The timing system of an engine determines how the engine runs, power it delivers, the fuel consumption and emissions of the vehicle. If any part is worn or damaged, this will directly affect car performance and potentially cause serious damage. Thus, it is vitally important to respond immediately to the warning signals of our vehicles.

Dolz’s Timing Chain Components

Industrias Dolz has expanded its range of products with the recent launch of timing chain kits. Dolz offers a complete range of Timing Chain Kits, including all components required for a professional repair, the highest quality to guarantee final users an effective replacement and an efficient and durable chain transmission.

The following are the timing chain components included in Dolz Chain Kits:

Timing chain

The timing chain is considered the heart of the engine, as it connects the crankshaft to the camshaft, controlling the opening and closing of the engine’s valves so that these happen at exactly the right time to inject fuel and remove exhaust gases in a balanced way. Some chains, to help installation, maintenance or replacement operations, have signaling links that offer visual aid for the correct positioning.

Camshaft/Crankshaft Sprockets

Sprockets are the mechanical components capable of transforming a circular force and motion into linear motion and force (and vice versa). In this way, the crankshaft, the driving part, transforms its circular movement into a linear one so that it is transported through the chain to the different driven elements (camshafts, oil pump or others). Once the chain reaches each of these elements, another sprocket located in the driven part is in charge of transforming the linear movement of the chain into the circular movement necessary for it to run.

Sprockets, unlike pulleys where slippage can occur, always have a synchronous movement. That is, that for each chain link, the sprocket advances only one tooth and, for each tooth that turns a driving sprocket, the chain will displace only one link. Therefore, if the crankshaft rotates one tooth, all the driven sprockets of the timing will advance the same.

To break this highly static timing between a crankshaft and driven components, some engines use VVT (variable valve timing) sprockets on the valve shafts. These have the ability to move the relative position itself with the teeth of its corresponding pinion. In this way the camshaft is positioned before or after the point where it should be if it is a normal sprocket.

Sprockets can also have positioning marks.

Guides

Chain guides are necessary to prevent timing chains from vibrating, serving as a track to the timing chain. By addressing the positioning of the chains, they ensure the right arrangement of the chain along all of the engine components.

Guides can either be fixed or tilting:

• Fixed ones have two or more anchors.
• Tilting ones have one anchor point at most and, its final position, is achieved by using a tensioner that exercises pressure against the chain.

Tensioners

A tensioner is provided in order to control the timing chain properly surrounding the crankshaft sprocket and the camshaft sprocket. Combined with a chain guide, tensioners ensure that the timing chain is kept under proper tension. This way they prevent the chain from vibrating and slipping off the sprockets.

All Dolz kits have tensioners. These can be with a simple pusher, which require the tilting guide, or they can have the guide itself already incorporated into the piston plunger.

Gasket and Seal

It is necessary to properly seal the oil bath where the timing chains are located to maintain lubrication and prevent leaking outside. Dolz gaskets and seals isolate the chain kit operating compartment from the components and from outside.

Seals are placed between the dynamic elements, such as the crankshaft, to create a seal between the oil bath where the chain operates, and the external elements. The gaskets, on the other hand, are placed between static elements, such as the oil bath cover and the engine block itself.

However, the entire automotive industry has been recently amongst the most exposed verticals to the ongoing COVID-19 outbreak and is currently still amidst unprecedented uncertainty. 

This post addresses the effects of the COVID-19 crisis in the aftermarket, together with the opportunities posed for players in the industry.

Initial impacts of the Covid-19 crisis on the automotive aftermarket sector

Prior to the outbreak of the COVID-19 pandemic, the €226 billion European aftermarket auto parts business enjoyed a decade of high margins and steady growth in a stable environment, according to a report published by the Boston Consulting Group. Now the industry must prepare to recover from multiple fronts.

Disruption in the global supply chain

COVID-19 has had a significant impact on the supply chain and product demand in the automotive aftermarket sector. This has been triggered by lack of supplies and the breakdown of its own supply model.

For a long time, the automotive industry has been weaving complex global-scale supply chains based on maximum efficiency, rigorous punctuality and the supply of just-in-time parts. This just-in-time model, which had generated a competitive advantage for aftermarket providers, has caused problems in the distribution side of this sector.

Slump in demand for aftermarket products

The demand for commercial vehicle parts initially plummeted with the shutdown of all non-essential services. Uncertainty and the decrease of the activity in practically all sectors caused the automotive aftermarket in Europe to invoice -17% less than expected in 2020, according to a study by Mckinsey.

The pandemic has resulted in lower car density, fewer collisions and vehicle users with low incomes delaying avoidable repairs. The consequences of these factors have meant a decrease in traffic for the retail and workshop business, meaning fewer crash-repair jobs and many delays in inspections or discretionary repairs.

Emergence of growth opportunities for the automotive aftermarket sector

Changes in consumer buying behavior in favour of private vehicles

As a result of the pandemic, customers preference has switched from public transport to private transport. A report published by Greenpeace alerts about the tendency in favour of private car use in 2021.

On the other side, financial struggles will hinder the purchase of new vehicles due to budget constraints. Therefore, vehicle buyers are expected to opt for used cars. The increasing sales of used cars is already starting to boost the demand for automotive aftermarket parts.

The domestic economy contraction causing the purchase of new vehicles to suffer a slowdown also increases automobile fleet aging. The higher the average age of the vehicles, the higher the percentage of cars that will need reparation and revisions. 

This will also favour especially independent aftermarket players, allowing them to gain market share from original equipment manufacturers (OEM).

Positive forecast for the automotive aftermarket subsector

The automotive aftermarket landscape is gradually and constantly recovering this 2021. Although there is still a long way for the recession to back away and the GDP to settle back to normal, there are positive signs that support the recovery of this sector.

Now that restrictions have been easing, consumers have returned to their previous levels of car usage, even though many are still hesitant to use public transit. Service garages are also reporting that many clients who have been delaying maintenance in the last few months are now back and demanding more services than previously. 

Significant increase in digital channels and e-commerce volumes

The lack of stock on the side of automotive aftermarket suppliers and the boost of e-commerce and online purchase volumes has resulted in more end-consumers shopping for vehicle parts online. 

E-commerce players have therefore gained market share as end customers limited human contact, but must use their gains to build sufficient scale to compete long-term in the market.

This should not be only about offering an online channel from which to sell car parts. Digital players should ensure a frictionless experience with a responsive process that poses confidence on customers regarding the online shopping experience and the quality of the final products. Only in this way will these buying channels be able to survive.

Future trends of the automotive aftermarket

The automobile industry is observing an increase in the demand for hybrid electric cars in response to the increased prices of petrol and petrol engine-based automobiles, as well as new regulatory restrictions.

At Industrias Dolz we are aware of all the advances in the market to be at the forefront and offer the best products and services to our clients.
