TecD Performance Diesel Additives

Cleaning Agent

ActiveTecD and PowerTecD Performance Diesel both contain a special cleaning agent to attack deposits that form on intake valves as well as outside and inside fuel injectors. These hardened layers of carbon obstruct the flow of fuel, causing an uneven fuel spray pattern into the combustion chamber, compromising the combustion efficiency and ultimately leading to a loss of performance such as higher fuel consumption and loss of engine power.

The cleaning agent in ActiveTecD and PowerTecD Performance Diesel breaks deposits away from valves as well as the inside and outside of fuel injectors then leaves a protective layer to prevent build-up of power robbing deposits. With an enhanced combustion efficiency achieved, the engine will subsequently benefit from improved fuel efficiency, power restoration and a reduction in environmental emissions such as Hydrocarbon (HC) and Particulate Matter (PM2.5) emissions.  

Filtration

Tighter worldwide emissions regulations require ever-more efficient and technologically advanced engines. High-pressure common-rail (HPCR) diesel injection systems require injectors with very small clearances (down to 2-6 micronmeters) to minimise leakage and uphold performance, making them more susceptible to deposit formation and wear from abrasive particulates.

PowerTecD is clean filtered using high performance systems at the terminal, to a Caltex guaranteed ISO cleanliness of 16/14/11 to meet the needs of modern, heavy duty diesel engines.

This removes the fine particulates plus one-way breathers on the tankers prevent airborne contaminants being introduced during loading and discharge, and our engineering team can assist with on-site filtration solutions to further maintain the cleanliness of the fuel. 

PowerTecD is available from Gladstone, Mackay and Newcastle.

Rust Inhibitor

Water and other fine particles in fuel can lead to formation of rust and corrosion of fuel system components over time. This can lead to corrosion particles entering the fuel stream and potentially restricting the fuel flowing through the injectors. At its worst, the rust and corrosion could cause the fuel system to fail. 

ActiveTecD and PowerTecD Performance Diesels contain a corrosion inhibitor that coats the internal surfaces of the fuel system and prevents the formation of rust and corrosion. 

Foam Inhibitor

Regular diesel produces foam during filling which can prevent fully filling the tank without stopping. The foam builds up inside the fuel tank and in the filler neck then triggers the fuel nozzle stop before the tank is filled. To fill the tank to capacity, you have to wait for the foam level to collapse and then restart filling. The process is repeated, often many times over.

This foam can also cause diesel to splash back during refuelling resulting in a messy fill experience. 

ActiveTecD and PowerTecD Performance Diesel eliminates most of the foam so you can fill up faster and without mess.

 

*Disclaimers:

The Fuel Efficiency Improvement result of up to 2.1% (at confidence level of approx 90%) was based on a fuel trial performed on three site-based diesel gensets whereby comparisons of results were done against unadditised XLSD, with specific trial and data analysis methodologies applied. It was found that higher fuel efficiency gains are obtained at the less engine efficient loads.

Caltex engaged an independent party to perform a fuel trial at its testing facility in Western Australia where the test engine was coupled to a dynamometer, and comparison of emissions reduction results were done against unadditised XLSD. Both Hydrocarbon (HC) emissions and Particulate Matter (PM2.5) emissions reduction results represent the overall trial change and was based on an industry standard test cycle with average engine duty of approximately 55%. HC emissions reduction result was with at least 90% confidence level and PM2.5 emissions reduction result was with at least 95% confidence level. HC emissions reduction at selected part load (at rated speed and 75% engine load) was up to 10.2%. 

The Power Restoration result of up to 100% was obtained by applying the CEC-F-98-A-08 (DW-10) industry standard test using a reference fuel.  

Note that all results may vary depending on the engine itself, environmental conditions, other factors such as variability in engine load factor and driver behaviours.
