Engine Specifications
|
Primary Engine
|
Engine Variants:
|
The 1982 BX was initially launched with a range of petrol engines derived from Peugeot/Talbot units, including: 1.3L (1360cc) and 1.6L (1580cc) XU series inline-four engines. Diesel variants (1.9D) were introduced shortly after.
|
Performance
|
1.6L (1580Cc) Xu5 Petrol:
|
Approx. 90 PS (89 bhp; 66 kW) at 5,250 rpm, Torque: Approx. 137 Nm (101 lb-ft) at 3,250 rpm.
|
Fuel System
|
Fuel System:
|
Primarily carbureted (e.g., Solex, Weber) for petrol engines. Early models might have featured basic electronic fuel injection (EFI) in certain markets or later versions.
|
Fuel Type:
|
Unleaded gasoline (as it became mandatory in many markets) or leaded gasoline, depending on market regulations and engine tuning.
|
Engine Codes
|
Engine Codes:
|
XU5J (for 1.6L petrol), XU7J (for 1.3L petrol), XUD7 (for 1.9L Diesel - introduced later).
|
Engine Variants
|
1.3L (1360Cc) Xu7 Petrol:
|
Approx. 69 PS (68 bhp; 51 kW) at 5,500 rpm, Torque: Approx. 104 Nm (77 lb-ft) at 3,000 rpm.
|
1.9L Diesel (Xud7):
|
Approx. 60-67 PS (59-66 bhp; 44-49 kW), Torque: Approx. 110-120 Nm (81-89 lb-ft).
|
Maintenance
|
Service Intervals
|
Service Intervals:
