With VMs under pressure to conform with governmental emissions legislation, smaller capacity, forced induction combustion engines, both petrol and diesel, have gained a strong foothold in the passenger car and LCV sectors. As a result, turbocharger replacement is increasingly common in the independent service sector, according to Nissens, but it believes only the correct installation of a premium quality component will ensure a professional repair.
Nissens first introduced turbos into its aftermarket programme in 2018, as part of a dedicated plan to expand its engine efficiency and emissions range, to offer the independent sector a “premium replacement proposition that reflects the high genuine Nissens quality standards” of its existing product groups, particularly concerning thermal management.
As a result, Nissens built a specific team and invested in the design and production facilities required to deliver on its commitment and develop a turbo offering that is underpinned by comprehensive internal and external validation and test procedures, independently verified by bodies, such as TÜV; therefore, the range is designed and manufactured to match the OE unit and replicate engine performance, fuel economy, emissions standards and durability stipulated by the VMs.
Alongside its objective to develop a range of quality, Nissens has added convenience for both the motor factor and workshop, as all its turbos are brand new units that do not require the return of the old unit or are subject to any surcharge.
In addition, they are easy to install, as any necessary ancillary items – gaskets, stretch bolts and clips, prime oil – are included in the box, which makes fitting them a straightforward process, particularly as fitting instructions in both printed and online formats are also provided.
Depth of range
The growing offer, which consists of more than 270 part numbers, is also increasing in its coverage of the vehicle parc, presently standing at 3,200 OE references that, in addition to passenger and LCV applications, also includes trucks. This is already 51% of the UK market but will rise to 68% during the next year.
This range expansion includes the newest models and latest technology, so besides wastegate and variable turbos with pneumatic actuation, the company has recently developed a line of 23 turbos with electronic actuation, dedicated to the newest Euro 5 and 6 engines.
Advanced engine designs for premium segment vehicles are often equipped with electrically actuated turbos and to ensure engine performance, smooth and reliable control of the flow of the exhaust gases within the turbo is a necessity. In addition, higher diagnostics capabilities and excellent control stability requires them to have high-quality electronics, so the internal DC motor design and motorised elements also need to be of high precision and durable to enable long and trouble-free operation.
There are several benefits to electronically actuated turbos, not least because the voltage can provide a precise signalling control, as their electric actuation provides an accurate, smooth and fast control of the vane mechanism of a variable turbo, which means it can quickly react to fully match the given engine needs. It also doesn’t depend on the vehicle’s pressure/vacuum system, so has a simpler architecture.
Collaboration with HELLA
With the cooperation with experts within the field of electrification, several e-actuator turbos in the Nissens range for the latest Euro 5 and 6 engines are equipped with OE-manufactured electric units from HELLA. This actuator solution ensures the precise and reliable control of company’s variable geometry turbos.
Turbo assembly ends with the precise calibration of the electrical unit to allow the electrical actuator to deliver the necessary fine-tuned turbo flow control, which is needed for modern engines operating in various working parameters and specific applications.
In addition to products and range depth, Nissens also supports factors with comprehensive technical solutions that are essential for professional turbo installation, maintenance and troubleshooting.
