⚙️ Engine Specifications

Engine Options Overview:

The Vauxhall Omega (V700) was offered with a range of gasoline and diesel engines. Gasoline engines typically included 4-cylinder (2.0L, 2.2L) and V6 (2.5L, 2.6L, 3.0L, 3.2L) units. Diesel options included 2.0L and 2.2L turbo-diesel engines.

Engine Performance Notes:

Performance varied significantly by engine. The 2.0L engines provided adequate performance for daily driving, while the V6 engines offered strong acceleration and high-speed cruising capabilities. Diesel engines focused on economy and torque.

Fuel Delivery:

Multi-point fuel injection (MPI) for gasoline engines; Common Rail Direct Injection (CRDI) or Rotary Pump injection for diesel engines.

ECU Type:

Various ECUs depending on engine and year, likely Bosch Motronic or similar, with diagnostic capabilities accessible via OBD (On-Board Diagnostics) or specific Vauxhall diagnostic interfaces.

Emission Control:

Covers diagnosis and servicing of emission control systems, including catalytic converters, EGR valves, and EVAP systems, as required by regulations of the time.

🔧 Transmission

Standard Transmission Type:

Manual transmission (e.g., 5-speed)

Optional Transmission Type:

Automatic transmission (e.g., 4-speed or 5-speed, depending on engine)

Transmission Features:

The manual likely covers clutch operation, gearbox overhaul, synchromesh checks, and driveshaft maintenance for both manual and automatic units, including torque converter and valve body procedures for automatics.
