Toyota Turbodiesel engines engineered cleaner and more efficient

The engine (1GD-FTV) is the first in the world to benefit from Thermo Swing Wall Insulation Technology, making it one of the most thermally efficient on the market; its thermal efficiency rating is 44 per cent.

Although it is smaller than the 3.0-litre engine it is replacing, it offers 25 per cent more torque. Usefully, there is 11 per cent more torque available at low revs, and customers will appreciate a 15 per cent improvement in fuel economy.

As well as appearing in Land Cruiser, the engine is powering new Far Eastern market versions of Hilux. The same engine group will also feature a new 2.4-litre direct injection turbodiesel (2GD-FTV).

New engine features

In testing, the new engines have proven their high thermal efficiency, quiet operation and powerful performance in worldwide locations, including extremely cold environments, where temperatures can fall to -40°C, and at high altitudes above 4,500 metres.

Toyota has also been able to make the engine catalyst 30 per cent smaller and has reduced the number of exhaust layouts from 18 to just three, simplifying the engines’ deployment worldwide and reducing the environmental burden.

Next generation advanced thermal insulation diesel combustion

Key to the performance of the new engines is the world-first application of Thermo Swing Wall Insulation Technology, together with a SiRPA (a silica-reinforced porous, anodised aluminium coating) on the pistons – reducing the cooling loss during combustion by about 30 per cent. SiRPA’s high insulation and dissipation qualities make it easy to heat and to cool.

The air intake port has been shaped to allow a significant increase in the amount of airflow into the cylinders; the piston combustion chamber shape has been revised; and the common rail fuel injection system allows for more advanced pressure control and injection optimisation. Air consumption is maximised, which enables high thermal efficiency and low emissions to be achieved.

Precise pilot injection, matching the state of the ambient air, takes place ahead of the main injection to shorten ignition delay. This means stable combustion is achieved, even in harsh environments, together with quiet running and high thermal efficiency.

Compact, high-efficiency variable geometry turbocharger

The GD engines use a new turbocharger that is 30 per cent smaller than its predecessor. Produced in-house by Toyota, it has a new turbine that improves efficiency and a new impeller that gives instantaneous throttle response and allows maximum torque to be obtained over wide engine rev range.

Toyota-first urea selective catalyst reduction system

Using Toyota’s proprietary, compact, high-dispersion urea selective catalyst reduction system eliminates up to 99 per cent of NOx emissions, one of the principal causes of air pollution. This helps the engine conform to Euro 6 and other international emissions standards.

Production and markets

The current KD family of engines will be phased out gradually and replaced with the new GD units, By 2016, production will reach about 700,000 units a year, available in around 90 world markets. Toyota aims to increase this number to at least 150 by 2020.

Toyota will continue to position diesel engines as a key component in its engine line-up, true to the philosophy of providing the right vehicles for the right places, at the right time. The entire Toyota group, including Toyota Industries Corporation, will combine its energies to develop cleaner and more competitive diesel engines for a wide range of vehicle types, taking into account the varying needs of people around the world.

    1. Hi Jim,
      We’d need to take your VIN or registration number to check this. Please could you provide us with one of these and we’ll look into it.

      1. Hi Jim,
        We’ve checked with our technical team and they have advised us that your vehicle will still have DPF.

      2. Thanks

        I’m now having and issue a loud constant beep that come on whenever I put the Hilux in reserve, sson as the lever is moved out of reverse it stops? any ideas?

        It was intermittent now is every time



      3. Hi James,
        We’d advise taking your Hilux to your Toyota Centre. They’ll be able to inspect your vehicle and advise.

  1. Hi Ella

    I need some advice on the DPF, the sales at Vertu said they are covered by the 5 year warranty but only if we follow the regeneration process, I cant seem to find out what this is?

    Can you help

    1. Hi James,
      Toyota sell/market a ‘Genuine Toyota High Quality Diesel Injector Cleaner PZ46300PC004’ via the Centre network and the eBay ‘Toyota Official Store’. You could make regular use of such a product, this could help reduce soot levels and improve diesel engine emissions. The product is listed at around £12 an (as at July 2016) on the Official Toyota eBay store.

      1. Thanks but this does not answer my question, can you please let me have an answer to my question.



      2. Hi James,
        We’re sorry this does not answer your question. Your dealer should be able to advise what the best method to do this is. Have you spoken to one of our technicians about this?

      3. Hi, thanks.

        They have referred us to you, for your technical team, we assume as Toyota you will be able to give us the correct information

        So to summarize the the DPF is covered by the warranty, if it is regularly regenerated, is this correct



      4. Hi James,
        We’ve passed this query on to customer relations as it is a DPF query. We have taken note of your email address and someone will be in touch via email soon. Many thanks and sorry again for your inconvenience.
