The new TOYOTA LandCruiser J7 with V8-D4D-Turbodiesel – now available!
The new V8-diesel-engine is replacing the 1HZ, 1FZ-FE und 1HD-FTE-engines in Australia and is a sensation quite honestly: A V8-D4D-Turbodiesel for the Heavy-Duty-LandCruiser! Although intended for the australian market only, you can buy the J7 with the husky commonrail-diesel-engine direct from us! Originally beeing a right-hand-drive vehicle (Australia!), we modify it to a left-hand-drive vehicle on request!
The J7-V8-versions are identifiable by the characteristic flat air-scoop at the hood:
This engine complies to EURO4-standard serially. Technical specifications are as follows:
Internal Identifier: 1VD-FTV
Engine: V8 DOHC D4D-Commonrail Diesel (4 valves/cylinder) turbocharged, with intercooler.
Cubic capacity: 4461 cm3
Bore / Stroke: 86,0 / 96,0 mm
Compression ratio: 16,8 : 1
Max. Power: 151 kW (205 PS) at 3400 Umin
Max. Torque: 430 Nm (from 1200 to 3200 Umin!)
If you relate this engine to other top-notch-high-power diesel engines of other brand, even ones build by Toyota themselve, the power provided by the 1VD-FTV seems not to be too impressive. But intentions and aim by designing this engine have been different from “normal” high-power diesel-engine to be used in modern common passenger car. Which Toyota is able to build as well! One should keep clearly in mind, under which conditions these engines will be used. Its normally working environment is the australian outback and the deserts and wilderness of africa: These are environments, which are different as chalk from cheese to european autobahn and american highways in particular. Most of the time beeing far, far away from the next service center providing computers and high-speed-connection to the world-wide-web to read out error-messages and re-elevate the causation of minor faults, these engines have only one duty: To function by all means – because “Mobility Warranty” is effectless in the outback…
The 1VD-FTV consists of a graphite-iron-engineblock with aluminium-alloy cylinder heads. Combustion air is lead through a intercooler, accelerated by a watercooled turbocharger and is fed to the intakes by two electronical controlled throttle-bodies (one for each cylinder bank).
Cylinders are arranged 90-degree-V-shape. The crankshaft is equipped with seven counterweights and supported by 5 bearings. The engineblock has been provided with forceful stiffener to reduce mechanical vibrations. Pistons are also made from aluminium-alloy and with cooling duct, piston crowns providing combustion chamber. Piston skirts are coated to reduce friction-loss. Injectors at the cylinder bottom are spraying engine-oil direct to the bottom of the piston to improve cooling and lubrication. Piston rods are forged from high-strength steel. Design features of the cobustion chamber are 4 valves and pivotal-located magnet-high pressure-injection nozzle to provide high power output and low emissions. The fuel-injection-system uses pilot injection to optimize power output and fuel-consumption. Glow plug is located between the intake-valves to optimize the start performance of the V8-engine.
Valve operating transmission is done by four chaindriven overhead camshafts to ensure exact valve timing at any speed (DOHC for each cylinder bank). Valves are maintenance-free and valve activation is done by roller rocker arm with needle bearings.
A special interference-tube connects exhaust-gas-routing of both cylinder-banks therefore providing indentically exhaust-gas-pressure which leads to optimized efficancy of turbocharging, resulting into a extremly flat and wide torque curve with highranged, useful torque between 1200 and 3200 rpm!
In other words: From slightly raised “idling” up to short before cutback speed, the engine provides a consistant high amount of torque!
Power transmisson ist done by a modified H150F 5-speed-manual transmission with a specially reinforced single-disc dry-clutch.
Further characteristics of this engine are continous temperature-controlled fan, fuel-radiator, special fuel-filter with alarm-function and oxidation-catalytic-converter for exhaust-detoxification.
