As you would have known by now, the outgoing Toyota Hilux will soon be replaced with the new, eight generation Hilux. With it, two brand new diesel engines will debut, possibly replacing the current 2.5-litre (2KD-FTV VNT) and 3.0-litre (1KD-FTV) diesel mills.
In place of the ageing engines are the 2.4-litre and 2.8-litre turbocharged oil burners, codename 2GD-FTV and 1GD-FTV. Both engines will be making its UK debut in the new Land Cruiser, and Toyota claims that the engines represent the company’s first fruits of achieving much better fuel efficiency, lower emissions and quieter operation through advanced new design and technology.
|Displacement (cc)||2,754 (2.8-litre)||2,393 (2.4-litre)|
|Bore x Stroke (mm)||92.0 x 103.6||92.0 x 90.0|
|Max Power (bhp @ rpm)||174 hp @ 3,400 rpm||148 hp @ 3,400 rpm|
|Max Torque (Nm @ rpm)||450 Nm @ 1,600 – 2,400 rpm||330 Nm @ 1,600 – 2,000 rpm|
|Low-Speed Torque (Nm @ rpm)||370 Nm @ 1,200 rpm||330 Nm @ 1,200 rpm|
Although the 2.8-litre is smaller in size compared to the current 3.0-litre lump, it offers 25 percent more torque and 11 percent more low-rev torque. Fuel efficiency is also said to improve by as much as 15 percent.
One of the major leaps in designing this engine is its new exhaust layout. Instead of having 18 layouts, the new engines have just three, simplifying its deployment worldwide, therefore reducing environmental burden. They also feature Thermo Swing Wall Insulation Technology with SiRPA (a silica-reinforced porous, anodised aluminium coating) on the pistons that reduce cooling loss during combustion by about 30 percent. The said feature is a world’s first application, and gives the engines a thermal efficiency rating of 44 percent.
Next, the air intake port is specifically shaped to significantly increase airflow into the cylinders. Also revised are the piston combustion chamber and common rail fuel injection system. This lean-burning combination increases power output as well as making the engines more fuel efficient. The GD engines have a new turbocharger that’s 30 percent smaller than the KD engines, and is produced in-house by Toyota. It gets a new turbine and impeller, giving it instant throttle response and allows maximum torque to be obtained over a wider rev range.
Despite being more powerful, both the engines comply to Euro6 emissions standard, thanks to the use of Toyota’s proprietary, compact, high-dispersion urea selective catalyst reduction system that eliminates up to 99 percent of NOx (mono-nitrogen oxides made of nitric oxide and nitrogen dioxide) emissions. NOx is the byproduct of high temperature combustion.
By 2016, Toyota claims that they will reach a production capacity of 700,000 engines a year and will be available in 90 world markets – Malaysia included. The company plans to increase this availability to over 150 world markets by 2020, and will gradually phase out the current KD engines.
