Toyota 1GD-FTV 2.8D Engine Specs, Problems, Reliability. The new engine series named as GD came out in 2015 replacing the KD engine series – the most widespread 4-cylinder diesel engines produced by Toyota. The 1GD-FTV engine became a replacement for its predecessor – the 3.0 L 1KD-FTV engine. The new 2.8-liter diesel initially was used in Toyota LandCruiser Prado and later on in other Toyota’s SUVs like Toyota Fortuner and Toyota Hilux.
The 1GD-FTV has a conventional cast iron cylinder block without liners. Like the 1KD, the new engine also geared up with 2 counter-rotating balance shafts. The balancing system is located in a different housing under the engine block and driven by a chain from the crankshaft. Some engine versions (for instance, in Toyota Hilux) do not have stabilizing unit for a cost decrease.
The cylinder head is made from aluminum alloy. There are 4 valves per cylinder (two consumption and 2 exhaust valves) or 16 valves total. The brand-new head has better intake air flow and enhanced shape of combustion chambers. On top of the head, there are two chain-driven camshafts (consumption and exhaust camshafts). The crankshaft doesn’t have a direct connection with camshafts. The 8.0 mm pitch timing chain is driven by a sprocket on a high-pressure fuel pump. The crankshaft drives the high-pressure pump by a single-row roller chain with pitch 9.525 mm. The valves are activated by roller rocker arms geared up with hydraulic tappets.
The GD engines are equipped with Common Rail direct fuel injection system. The pressure in the system is 35-220 MPa (5000-32000 psi). That excellent numbers are reached thanks to the HP5S type high-pressure pump. All components of the fuel system are made by Denso. The 1GD engines were geared up with variable nozzle turbines (VNT) also called variable-geometry turbochargers (VGT) and air-to-air intercoolers. The intake manifold also has valves opening and closing one of two consumption ports for each cylinder to enhance the combustion procedure. The throttle body is electronically controlled; the throttle valve is driven by an electrical motor.
Depending on the market area and emission standard, the engine has a different quantity systems for emission decrease. The complete list includes the EGR, SCR, dpf, and doc. The brand-new engine in comparison with its predecessor (1KD) ended up being 15% more fuel efficient and 25% more torque. According to Toyota quotes, the thermal efficiency of the brand-new engine is 44%.
Toyota 1GD-FTV 2.8D Engine Problems and Reliability
The Toyota’s 2.8 L diesel has a short report history yet. Numerous owners have actually already come across some problems with the diesel particle filter or DPF and high oil intake from the first miles. After that, the new engine software upgrade was launched to remove these problems. Just time will inform how it will affect reliability.
The previous diesel series has already become obsolete in a number of parameters – fuel consumption, sound, power, emissions. The 1GD-FTV is a contemporary and technological advanced engine compared to the 1KD-FTV, but the performance specifications are modest and all the advantages are smooth peaceful operation and much better emission standards.
