Superb levels of power, economy and refinement for Land Rover LR4.
The LR4 engine provides outstanding power, torque and refinement and harnesses
the latest technology to deliver outstanding drivability and performance. With a
torque activated dual independent variable camshaft phasing system, it offers an
immediate driver-focused reaction to throttle inputs and driving circumstances.
The LR4 engine’s camshaft torque actuated, dual independent Variable Camshaft Timing system
continuously controls camshaft timing to deliver an optimum balance of power, efficiency and
emissions. The chain driven camshaft timing units are mounted on the end of each camshaft to
advance or retard camshaft timing and alter the camshaft to crankshaft phasing. Camshaft Profile
Switching features two completely different intake camshaft profiles machined into the same
camshaft. The engine management system chooses the camshaft profile depending on running
conditions and torque demands: one profile for low-speed/low-load driving; the other, with longer
valve lift, for higher-speed/higher-loads.
The fueL injecTion sysTem achieves high standards of durability, combustion performance and
refinement. The ultra-precise machining of high-pressure injectors ensures a fine-quality spray of
fuel into the combustion chambers and optimizes combustion conditions both at cruising speed and
during acceleration. The engine uses a high-pressure, steel fuel rail. Fuel in the rail is detected by a
high-pressure sensor which controls flow into the rail by adjusting an electromagnetic valve in the
high-pressure fuel pumps’ outlet.
