Toyota 1CD-FTV engine
Content
Toyota Corporation marked the beginning of the third millennium with the release of the first mass-produced diesel engine manufactured using Common Rail technology. Replacing the AD series, the 1CD-FTV engine is a 2,0 liter power unit designed exclusively for use in the European automotive market. Hence the complaints about the reliability of stability. But don't get ahead of yourself. About everything - in order.
Structural features
The 1CD-FTV is an in-line four-cylinder internal combustion engine with a direct fuel injection system into the cylinders. The sixteen-valve timing is assembled according to the DOHC scheme, with two camshafts. Timing belt drive, with automatic hydraulic tensioner. The cylinder head is made of aluminum alloy, the cylinder block itself is traditionally cast iron.
Significant changes also affected the design of the piston. A combustion chamber was placed in it, a wear-resistant niresist insert appeared, a branded anti-friction coating was applied to the skirt.
Another component of the toyota 1CD-FTV engine that has undergone deep processing is the turbocharger. The main changes relate to the installation of movable guide vanes in the turbine. At idle, when the exhaust gas flow rate is low, the blades are in the “closed” position. With an increase in the load on the engine, and consequently, the speed of the outflow of gases, the blades change their position to "fully open". Thus, the optimal speed of rotation of the compressor of the turbocharging system is ensured.
Fuel injection system
Unlike the previously used multiport injection system, fuel is supplied to a common fuel rail, and then, through piezoelectric injectors, it enters directly into the engine cylinders. The high pressure fuel pump or injection pump provides a much higher fuel pressure, 1350 atmospheres versus 200 for systems with distributed injection.
The need for such an innovation becomes clear from a detailed analysis of the operation of piezoelectric injectors. The system works with a preliminary injection of a small amount of fuel, about 5 mg, which significantly reduces the amount of harmful inclusions in the exhaust gases. But at the time of the main injection, the pressure in the cylinders is already so high that the standard injection pump simply will not “push” the fuel into the nozzle.

Disadvantages of 1CD-FTV
Oddly enough, 1CD-FTV d4d does not contain technical blunders worthy of special mention in its design. The traditional lack of repair dimensions makes the engine almost disposable, but this is more of a Toyota brand name.
What is the reason for the stories of some owners about "getting into expensive repairs"? Everything is very simple. The engine is intended for use in Europe. The quality of domestic diesel fuel is very unstable, it may contain water and mechanical inclusions. Once in the injection pump, the smallest foreign bodies turn into an excellent abrasive material. The result is a gradual loss of pressure in the fuel system, and then, as a systematic result, a pump failure. Water, in the form of a finely dispersed mixture, "with a bang" takes out nozzles.
Also, the unstable operation of the sensor responsible for the oil pressure in the system causes criticism. With standard indicators determined by the test pressure gauge, the sensor often signals an emergency.
What cars is installed
Despite the apparent unreliability, 1CD-FTV is successfully used on Toyota models:

Bullshit!
First, the most powerful version is not 114 horses, but 116
Second - the nozzles are piezoelectric and electromagnetic
Third - it says above that the engine is reliable, then suddenly it turns out to be unreliable, the nozzles in all diesel cars are a weak point, this does not make the unit bad!!!!
