Technical features

The TD4 engine has the following key features:

• 16-valve, DOHC layout, 4 valves per cylinder.
• The fuel injectors are located centrally relative to the combustion chamber.
• Roller valve levers with hydraulic clearance compensators.
• Garrett variable nozzle turbocharger with rotating electronic actuator (REA).
• Pierburg electronically controlled EGR valve with Visteon EGR heat exchanger.
• Bosch 3rd generation fuel system with common rail fuel injection technology.
• Piezoelectric injectors with 7 holes (provide 5 injections per working stroke).
• Improved Bosch EDC 16 engine management system.
• The intake manifold features adjustable vortex formation and port shut-off technology.
• Electronic intake throttle valve for controlled engine shutdown.
• Balancing system.
• Aluminum alloy cylinder head and double-walled cast iron cylinder block.
• The design of the cylinder head ensures optimal air swirl formation across the entire range of engine crankshaft speeds.
