Toyota KD engine

From Wikipedia, the free encyclopedia

The Toyota KD engine series is a diesel engine, produced by Toyota, which appeared in 2006.

[edit] 1KD-FTV

First appeared in the 2000, the 1KD-FTV is one of the newest engines build by Toyota. 1KD-FTV a 3.0L (2982cc) straight-4 common rail variable nozzle turbo coupled with a 32-bit ECU and Multi Pilot Injection System, diesel engine Turbo diesel engine with an Intercooler. It has 16 valves and a DOHC (double overhead camshaft). Bore is 96 mm and stroke is 103 mm. It powers 170 hp(125 kW) at 3400 rpm, and 253 ft·lbf (343 Nm) of torque at 1800-3400 rpm. Redline of this engine is at 4200 RPM. Compression ratio is 17.9:1. This engine uses D-4D electronic Common Rail (Common rail direct fuel injection ) technology, produces ultra high pressure, which is about 8 times more than the pressure of the normal fuel injection system. This combined with the 32-bit ECU which controls fuel quantity, valve-timing, and accurate pressure at different engine revolutions result in the most fuel economy and also in the full utilization of power, whether it is during taking off or during taking over, without having to drag the engine revolution to the maximum. Making the achievement with the fuel consumption 11% more effective compared to its predecessor 1KZ-TE engine thus 17% more powerful. Fuel consumption is also 12% more effective than the all new Toyota Hybrid engines. The Pilot Injection System helps smooth engine running like sitting in saloon cars. The noise level is only 49 decibels at the idle speed. The Pilot Injection System produces fuel injection in advance before the main injection starts working, reducing Ignition Lag Time and resulting in continuous and complete combustion. Noise from ignition is also reduced.

This engine was first used in Toyota Land Cruiser Prado and now used in the Toyota Fortuner and Toyota Hilux.

[edit] 2KD-FTV

The 2KD-FTV is the 2nd generation of the KD engine with a smaller 2.5L (2494 cc) straight-4 common rail variable nozzle turbo coupled with a 32-bit ECU and Multi Pilot Injection System, diesel engine. Like 1KD-FTV, it has 16 valves and is a DOHC engine. Bore is 92 mm and stroke is 93.8 mm. It powers 102 hp (75 kW) at 3600 rpm and 191.7 ft·lbf (267 Nm) of torque at 1600-2400 rpm. Redline of this engine is 4400 RPM. This engine also uses D-4D Common Rail (Common rail direct fuel injection ) technology. An intercooler will be introduced next year into this engine.
