"The technically advanced Toyota D-4D is a common rail four-stroke diesel engine with direct injection."
How does it work?
The secret of the Toyota D-4D’s outstanding performance is an electronic control unit that accurately balances fuel injection pressure, timing and volume according to how the car is driven and the demands being made on the engine.
Using Piezo-electric injectors, common rail technology injects finely atomised fuel at high pressure directly into the combustion chamber, including a small amount of fuel just before the main fuel load ignites. This ‘pilot burn’ lowers the explosive force of the main combustion process and goes a long way to reduce the noise and vibration formerly associated with diesel engines.
- The engine always works at maximum efficiency
- Power and torque optimised
- Excellent fuel economy
D-4D provides much quieter diesel power, virtually indistinguishable from a petrol engine when driving almost closing the NVH gap with petrol engines
More power, torque and flexibility make a D-4D powered car superior to older diesel technology
New lower emissions 2.0 D-4D engine available in new 2012 Avensis
The revised 2.0 D-4D diesel engine in the new 2012 Avensis features lower CO2 emissions and greater fuel efficiency – yet delivers smoother torque across the range. Fuel consumption has improved by 13% to 61.4mpg (combined cycle) and CO2 emission have been reduced by 19g to 120g/km while not compromising on performance by delivering 124bhp. The revised engine allows Avensis to be subject to annual road tax of just €160.
Hilux is available with 2.5l and 3.0l engines.
Choose form two capable and efficient turbodiesel D-4D engines. Both the 2.5 litre version and the 3.0 litre version are full 4WD. 2.5 litre grades have a 5-speed manual transmission while 3.0 litre grades have a choice of 5-speed manual or 5-speed automatic transmissions. Both deliver excellent low speed torque and high speed power, and are equipped with a Diesel Particulate Filter (DPF) to minimise emissions.
Diesel Particulate Filter (DPF)
"The Diesel Particulate Filter (DPF) catalyst oxidises hydrocarbons and carbon monoxide into harmless substances, like a conventional catalyst, but also simultaneously reduces Particulate Matter"
How does it work?
The exhaust gases flow through the filter’s substrate walls where the Particulate Matter is trapped and collected. A regeneration process, triggered by the engine management system, then burns off the soot.
The DPF is self-cleaning and requires no long-term maintenance. Particulate Matter is easily inhaled due to its small size, and can be very harmful.
