Vacuum pump is driven by front side of intake camshaft and fuel supply pump by exhaust camshaft rear side. Chain tensioned by hydraulic tensioner with ratchet mechanism. The exhaust camshaft driven by roller chain (pitch 9.525 mm), inlet - by gear from the exhaust. Valve Mechanism - DOHC 16V: double camshafts in the head and four valves per cylinder. EGR channels are inside the head, the exhaust fuel injector is installed in exhaust port of cylinder 4 (with DPF). Each cylinder has four valves, there is the tip of vertically mounted injector in the center of the combustion chamber and glow plug between the intake ports.

The pistons are connected to the rods with fully floating pins.Ĭylinder head made of alloy. The groove for the upper compression ring have ni-resist insert, there are cooling channel inside the piston head and polymer coating is applied on the skirt. Pistons - aluminium, full-sized, with a combustion chamber in the head. Of course, no overhaul with reboring provided.Īlloy crankcase with fused iron bearing caps for crankshaft main journals attached (similar ZZ series).ĢAD engines have gear driven balancing mechanism. Thin-walled iron-cast liners are fused into a alloy block and their special rough outer surface promotes maximum connection and an improved heat dissipation. Application: Auris 150, Avensis 250.270, Corolla Verso 10, RAV4 30.40, Verso 20, Lexus IS 200dĪD series - the second Toyota's experience in manufacturing 'disposable' diesel - with aluminium 'open deck' cylinder block.

Engine weight with fluids filled - 180-200 kg.ĪD series satisfied the requirements of model range, however performance is not 'outstanding' - the main competitors from Hyundai have specific output by at least 10% higher, Koreans also offers more variants with automatic transmissions, and, oddly enough, the more proven reliability.ġAD-FTV (2.0 D-4D). AD series engines were used for C/D-class passenger cars and SUVs for the European market and emergency markets in 2005-2018.
