What is Toyota Adblue ? 

DENSO Introduced the common-rail diesel system primarily to bring down NOx levels and black diesel smoke with Adblue. The primary features of this system are

  • Improved Fuel economy
  • Noise Reduction
  • High Power output

The common-rail system meets the Step 3 (Euro3) stage of the European Emission regulations. With some minor improvements in DPF (Diesel Particulate Filter) , implementation of AdBlue.

 

Emission Components

All modern clean diesel engines have 3 major emission components

  • DPF (Diesel Particulate Filter)
  • NOX catalyst (with or without Adblue)
  • Oxidation catalytic converter

What is DPF?

A diesel particulate filter (DPF) is a filter that captures and stores exhaust soot. The primary function is to reduce emissions from diesel cars. But because they can choke easily due to soot formation. They need to be emptied or periodically cleaned. This is termed as regeneration of DPF. This was introduced as a Euro 5 exhaust emmission regulation and in some countries it is illegal to remove it permanently from the exhaust system. DPF have shown to cause drivers a lot of problems if the cleaning process in interrupted.

 

If DPF is blocked / clogged you may see this light turned on the Instruments Cluster.

 

Symptoms of a choked DPF

You may get following symptoms if the On-board system is cleaning DPF automatically

  • Change in Engine Sound
  • Running of cooling fans
  • Increase in Fuel consumption
  • Increase in idle speed
  • Exhaust Smell

What is AdBlue?

AdBlue is a colorless liquid that is made from a mixture of high-purity urea and deionized water. The solution is an essential component of selective catalytic reduction (SCR) technology, which is one of the most effective systems for reducing the nitrogen oxide (NOx) levels in the exhaust fumes that exit diesel engines. NOx is one of the most harmful pollutants emitted by engines, as it reacts with other gases in the atmosphere to form small particles and ozone, both of which can damage sensitive lung tissue in humans and animals.

 

When the fuel is burned by the engine, AdBlue is injected into the SCR catalyst in order to convert the NOx into a less harmful mixture of nitrogen and water vapor. The solution is stored in its own tank, separate from the diesel, before being added to outgoing exhaust gas by a dosing control system that supplies enough AdBlue to make up 2–6% of the total fuel consumption. In the SCR catalytic converter, the urea present becomes ammonia when heated, reacting with the NOx in the emissions to convert the pollutants into nitrogen, water, and a small amount of carbon dioxide.

SCR catalytic converter

To buy AdBlue you can call us @ 0303-2227989. Toyota Prado and Landcruiser diesel that are imported into Pakistan usually require Adblue.

Back to 1KD and 2KD overview

These engines are exceptionally quiet and provide a great torque at lower RPM,s as well, thanks to the on-board Computer controlled fuel pressure and injection timings through the ID matched injectors, the engines have shown up-to 20% better throttle response and fuel average. Popular models in Paksitan having 1KD and 2KD engines are Toyota Vigo Thailand and Invincible (UK), Vigo Champ Pakistan and Toyota Hiace vehicles. These engines mostly have an inter-cooler and all have a Turbo.

1KD and 2KD run smoother because of injection of a pilot charge in cylinders using the same injectors, A pilot charge is a spray of a diesel before the spray of the main fuel that assist in complete combustion of the diesel fuel.

 

Long life of 1KD and 2KD

These engines have a long life span if timely serviced using Genuine parts of Toyota. For service of Any 1KD or 2KD you can call us at
