Toyota has introduced a new line of turbocharged diesel engines with more torque, greater efficiency and lower emissions.

The company said the new GD engines feature next-generation advanced thermal insulation diesel combustion to reduce cooling loss significantly.

In-house trials showed the use of Thermo Swing Wall Insulation Technology (TSWIN) helps make the 2.8-litre 1GD-FTV engine one of the most thermally efficient, with a maximum thermal efficiency of 44 percent, Toyota said in a statement.

Despite smaller engine displacement in comparison to the current KD engine, maximum torque is improved by 25 percent and low speed torque improved by 11 percent, while fuel efficiency has received a 15 percent boost.

Toyota will gradually phase out the current globally deployed KD diesel engines and replace them with GD engines.

By 2016, production will reach approximately 700,000 units a year with introduction in approximately 90 markets, set to expand to at least 150 markets by 2020.

The newly developed 1GD-FTV is available in the Hilux pickup truck, and Land Cruiser Prado (aka. Lexus GX, GX470).

The same engine lineup includes the 2GD-FTV 2.4-litre direct-injection turbo diesel engine.

Toyota’s new compact high-efficiency variable geometry turbocharger used by the GD engines is 30 percent smaller than its current equivalent, and features a newly developed turbine that improves efficiency, and a newly developed impeller that provides instantaneous acceleration response and produces maximum torque over a wide range of RPM.

By reducing size and increasing efficiency, the newly developed turbocharger with the GD engine delivers approximately a 50 percent faster response in the rate of boost pressure increase.
