Description of the DW10TD engine

DW10TD is characterized by a reliable design and easy maintenance. Here are the main features of its device:

1. Cylinder block: Cast iron, in-line, four-cylinder block without liners. This design provides durability and resistance to high loads.
2. Cylinder Head (Cylinder Block Head): Aluminum 8-valve cylinder head with a single camshaft. This simplifies construction and reduces engine weight.
3. Fuel system: Common Rail Bosch CP1 or Siemens SDI 801 is used, providing precise fuel metering and improved combustion efficiency.
4. Turbocharger: Turbocharger without controlled geometry and intercooler. This configuration ensures stable performance with moderate power.
5. Gas Timing Drive (GTD): Toothed belt. The timing belt is durable and quiet, but requires regular replacement.
6. Hydrocompensators: Present, eliminating the need for manual valve adjustment, simplifying engine maintenance.
7. No FAP Filter: This engine does not utilize a particulate filter (FAP), which reduces operating costs and simplifies maintenance.
8. Flywheel: Single mass flywheel for simplicity of construction and reduced chance of breakage.

Disadvantages:

• Power: For this engine displacement, power may not be enough, especially in heavier vehicles.
• Transmission belt: If the timing belt breaks, the rockers can break, requiring immediate repair.
• Damper pulley: Frequent problems with the damper pulley, its life often does not exceed 30-50 thousand kilometers of mileage.
• Pressure regulator: A clogged pressure regulator filter can cause thrust failures; cleaning or removing the filter is common.

Peugeot DW10TD engine maintenance schedule

Typical faults

1. Crankshaft damper pulley: Problems with this component were common, especially in the early years of production.
2. Pressure regulator filter clogging: May cause draft failures and require regular cleaning or removal of the filter.
3. Pump: The electric pump in the tank can fail, especially if driven frequently with little fuel.
4. CR system tandem pump: Tandem pump failure requires disassembly of the fuel pump and specialized repair.

The DW10TD engine generally shows good reliability and performance, but requires regular maintenance and attention to detail to keep it in good condition. Proper maintenance can significantly extend the life of this engine and keep its efficiency at a high level.
