1-KD FTV D-4D Engine in Toyota Hilux Vigo

By Jack Kates

d-4d-engine-1 KD FTV engine for Toyota HiluxFirst appearing in 2000, the 1KD-FTV is comparitively one of the newest engines built by Toyota.

The 1KD-FTV is a 3.0L (2982cc) straight-4 common rail diesel engine with a variable geometry turbocharger and Intercooler. It has 16 valves and a DOHC (double overhead camshaft) design. Bore is 96 mm and stroke is 103 mm. This diesel D-4D DOHC engine generates 170 hp (127 kW) at 3400 rpm, and 260 lbf·ft (352 N·m) of torque at 1800-3400 rpm. Redline of this engine is at 4200 RPM. Compression ratio is 17.9:1.

 

This engine uses Toyota's D-4D Common Rail fuel injection technology operating at ultra high pressures of up to 135 mpa (1350 bar or about 19,580psig) which is about 8 times more than the pressure of conventional fuel injection systems within a "common rail" that feeds the injectors on all four cylinders (older diesel engines have a separate line leading from the injection pump to each injector). This is combined with a 32-bit ECU which controls fuel quantity, valve-timing, and boost pressure at different engine parameters resulting in best fuel economy and also full utilization of power during acceleration. Pilot injection is also utilized by the common rail fuel system to smooth engine operation. Small amounts of fuel are introduced into the combustion chamber prior to the main injection event, reducing lag time and promoting more continuous and complete combustion. Exterior and interior engine noise is also reduced.

The 1KD engine produces 17% more power with 11% less fuel consumption than its predecessor, the 1KZ engine.

This engine was first used in Toyota Land Cruiser Prado, 3rd Generation Hilux Surf and now used in the Toyota Fortuner, Hiace and Toyota Hilux.
