PSA (Peugeot-Citroën) DW10ATED4 diesel engines are widely used in a number of car models due to their reliability and efficient operation. These engines, with a displacement of 2.0 liters, have two versions: atmospheric and turbocharged. Both variants have similar characteristics, but differ in power and peculiarities of operation.
Atmospheric DW10ATED4
The atmospheric version of the DW10ATED4 engine is a four-cylinder inline unit with a displacement of 1997 cubic centimeters. This engine develops 107 horsepower at 4,000 rpm and a maximum torque of 250 N*m at 1,750 rpm. With such characteristics, the engine demonstrates excellent fuel efficiency with a consumption of 5.4 liters per 100 km, making it suitable for urban conditions and long trips.
Key specifications of the atmospheric DW10ATED4:
- Volume: 1997cc
- Power: 107 hp at 4,000 rpm
- Torque: 250 N*m at 1750 rpm
- Fuel consumption: 5.4 l/100 km
- CO2 emission: 142 g/km
- Engine type: In-line, 4-cylinder
- Number of valves per cylinder: 2
This engine is characterized by moderate CO2 emissions and is quite environmentally friendly for its time. Its simple twin-valve per cylinder design and lack of turbocharging make it a reliable and easily maintained unit.
Turbocharged DW10ATED4
The turbocharged version of the DW10ATED4 has the same basic features as the atmospheric version, but is augmented with turbocharging, which greatly increases its performance. This engine also has a displacement of 1997 cc, but power is increased to 109 horsepower at 4000 rpm, and maximum torque reaches 270 N*m at the same 1750 rpm.
The DW10ATED4 turbocharged engine has the following specifications:
- Volume: 1997cc
- Power: 109 hp at 4000 rpm
- Torque: 270 N*m at 1750 rpm
- Fuel consumption: 6,7 – 8 l/100 km
- Engine type: In-line, 4-cylinder
- Compression ratio: 18
- Cylinder bore: 85 mm
- Piston stroke: 88 mm
- Valve drive: DOHC
- Number of valves per cylinder: 4
Thanks to the turbine and DOHC valve train (twin-shaft arrangement), the turbocharged DW10ATED4 is characterized by higher dynamic performance and better output at low speeds. However, this engine requires more complex maintenance and has higher fuel consumption – from 6.7 to 8 liters per 100 km.
Both variants of DW10ATED4 engine deserve attention, but their choice depends on the driver’s needs. The atmospheric engine will suit those who appreciate economy and ease of operation, while the turbocharged version will appeal more to drivers who demand more power and dynamism from the car. Regardless of the choice, both engines demonstrate reliability and durability, which has made them popular with Peugeot and Citroën car owners.

Disadvantages, Breakdowns and Problems of DW10ATED4 Engine
Despite its popularity and reliability, the DW10ATED4 engine has had a number of problems that owners have encountered. Here are the main ones:
- Crankshaft pulley
In the early years, many owners experienced the problem of replacing the crankshaft pulley. This problem was so common that it became a known flaw with this engine model. - Electric swap pump
The electric priming pump, located in the fuel tank, often failed. This caused fuel delivery problems and required the pump to be replaced. - Fuel Pressure Regulator
One of the weak points of the engine was the fuel pressure regulator. It often clogged, resulting in unstable engine operation and the need to clean or replace it. - Soot Filter
The particulate filter also caused a lot of problems to the owners. Its clogging was a frequent phenomenon, which reduced engine power and increased fuel consumption. Many drivers simply removed this filter to avoid problems. - Frequency of fuel filter replacement
Almost all other DW10ATED4 engine failures were related in one way or another to the frequency of fuel filter replacement. Changing the filter regularly could have prevented many fuel supply and quality problems.
Overall, despite its shortcomings, the DW10ATED4 engine remains reliable and in demand, especially among owners of the vehicles it was installed on. Proper maintenance and timely replacement of problematic components can extend the life of this engine and ensure its stable operation.
