Don’t be caught with frozen DEF GOSS OFFERS A RANGE OF AFTERMARKET EQUIPMENT FOR MODERN HIGH-PERFORMANCE DIESELS, INCLUDING HEATERS WHICH PREVENT FROZEN DIESEL EXHAUST FLUID

eeting each new emission standard brings new challenges and often new technologies for technicians to master. These systems ensure clean running but often come with new control modules, sensors, and mechanical components. To ensure compliance with emission standards, components with these systems will often put a vehicle into limp mode, or at a minimum set the malfunction indicator when not working correctly. As more vehicles are being built to Euro 6 emissions standards, Diesel Exhaust Fluid (DEF) solutions like Adblue are now more commonplace. The urea-based diesel exhaust fluid is typically made up of 67.5 per cent water and 32.5 per cent urea. It can freeze. Enter the DEF Heater, a component of the Selected Catalyst Reduction (SCR) control environment. A DEF control module is responsible for driving the DEF heater, reading a number of sensor inputs that can include the DEF tank temperature sensor, DEF supply pump temperature sensor, and outside air temperature sensor, usually provided by the MAF sensor. Based on this data, the heater is instructed to defrost the urea-based fluid within the tank itself. This can be achieved by a heating element, or a valve allowing engine coolant to circulate through a water jacket in the tank. The DEF heater is only one component of a proper SCR solution. It has multiple temperature inputs, running conditions, and multiple modes of operation, from basic heating, to thermal control, and start-up modes. While we don’t get down to the temperatures seen in northern hemisphere population centres, it certainly gets cold enough in New Zealand to freeze DEF, making DEF heaters a valuable preventive measure.

Delkor’s AGM and EFB target stop/start reliability KOREAN-MADE DELKOR QUALITY MEETS THE CHALLENGE OF HIGH DEMAND STOP/START SYSTEMS
D
elkor Absorbent Glass Mat (AGM) batteries are ideal for high-end and advanced fuel-efficient vehicles with high electrical demands, such as those with start/stop technology and regenerative braking. These vehicles start approximately 16,000 times more per annum (based on average CBD travel of 15,000km) than an average car. They require batteries capable of handling frequent cycling and high charging loads. Delkor Batteries says its patented ‘PowerFrame’ grid technology provides superior and consistent starting performance, with up to 70 per cent better electrical flow than other grid technologies in the market. Delkor Enhanced Flooded Batteries (EFB) are suitable for applications that operate at a partial state of charge, as required by stop/start vehicles, but which don’t require the deep-cycling capabilities of AGM batteries. Vehicles fitted with stop/start technology require batteries that can support the repeated demand for engine cranking power. That means either an EFB or AGM battery must be used and, as vehicles’ electrical systems are designed for specific battery types, it is always advisable to replace batteries with the relevant type.

Many vehicles are now set up to ‘register’ new batteries with the car’s battery management system (BMS). It must know which type of battery is installed in the vehicle to make full use of its potential. Installing the incorrect battery will lead to premature battery aging and failure. However, not all batteries are equal. Delkor’s EFB batteries feature a polyfleece scrim material added to the positive plate surface which helps to stabilise the active material of the plates, increasing their endurance. Delkor EFB batteries also benefit from PowerFrame grid technology, which delivers increased dynamic charge acceptance — critical for the regenerative braking systems used in ISS vehicles. Similar to AGM batteries, EFB batteries are also built to resist corrosion, which is the number one cause of car battery failure. The award-winning Delkor brand by Clarios has a reputation for quality and reliability. Delkor
has been awarded the Korean Standard-Quality Excellence Index (KS-QEI) award for 16 consecutive years from 2006 to 2021, which measures product quality and customer satisfaction. The manufacturing process of Delkor batteries strictly adheres to global product and process standards, from the production of raw materials through to shipment. Delkor AGM and EFB batteries are designed specifically to meet the evolving power requirements of modern day vehicles. Delkor AGM and EFB batteries are available exclusively at R&J Batteries, one of the fastest growing battery distributors in Australasia. R&J Batteries has branches in Wiri, Christchurch, Hamilton, and Albany in New Zealand, and 23 other branches in Australia. R&J Batteries has a comprehensive range of Delkor automotive, commercial, marine, leisure, and deep cycle batteries.
