Engine Family Bentley:
Typically the Bentley L-Series V8 (pushrod overhead valve V8), often turbocharged (e.g., Turbo R).
Displacement Range:
Commonly 6.75 Liters (6750cc).
Horsepower Torque Range:
Varies significantly by model and aspiration (NA/Turbo). Turbocharged models typically offered 200-300+ hp and significantly higher torque figures, reflecting their luxury grand touring purpose. Exact figures specific to each model are detailed within the manual.
Engine Aspirations:
Naturally Aspirated and Turbocharged variants are covered, with specific details for each depending on the model.
Fuel System Type:
Electronic Fuel Injection (EFI) systems, likely Bosch Motronic or similar advanced systems for the period, managing fuel delivery and ignition timing.
Fuel Pressure Specifications:
Specific fuel pressure values for the system will be detailed, critical for correct injector operation.
Throttle Linkage Description:
Mechanical throttle linkage with potential for electronic throttle control elements in some later EMS implementations of this era, or simple cable actuation.
Ignition Timing Specifications:
Factory-specified ignition timing advance curves and base timing settings for various engine conditions.
Transmission Type Rollsr:
Automatic transmission, typically a GM Turbo-Hydramatic 400 (TH400) or ZF 4-speed automatic, heavily adapted and tuned for Rolls-Royce applications.
Transmission Type Bentley:
Automatic transmission, often a ZF 4-speed automatic, with specific tuning for performance Bentley models.
Transmission Control Integration:
Engine management system interfaces with transmission control unit (TCU) for optimized shift points and drivability.
Infotainment Integration Ems:
Limited integration; infotainment systems of this era were basic and separate from engine management functions.
Driver Assistance Features:
No advanced driver-assistance systems (ADAS) were present on these models. Engine management focused on core powertrain control.
Connectivity Features:
N/A for these model years and focus of the manual.
General Service Intervals:
Typically 6,000-10,000 miles or 12 months for routine servicing. Specific intervals for ignition system checks, fuel filter replacement, and emission system diagnostics would be detailed in the manual.
Engine Oil Specification:
API SG or higher, viscosity grades like 10W-40 or 20W-50 depending on climate and specific engine recommendations. Exact specifications will be in the manual.
Coolant Specification:
Ethylene glycol based coolant, typically a 50/50 mix with distilled water. Specific OAT (Organic Acid Technology) or HOAT (Hybrid Organic Acid Technology) types may be recommended depending on factory fill.
Fuel Type:
Unleaded gasoline, typically 95 RON (Research Octane Number) or higher, depending on the compression ratio and tuning of the specific engine.
Brake Fluid Specification:
DOT 3 or DOT 4 hydraulic fluid. (Not directly EMS, but common maintenance)
Power Steering Fluid Specification:
Dexron II or equivalent automatic transmission fluid. (Not directly EMS, but common maintenance)
Common Issues Engine Management:
Potential issues include failure of engine control unit (ECU), faulty mass air flow (MAF) sensors, idle air control (IAC) valves, oxygen sensors, and fuel pressure regulators. Turbocharger systems may have issues with wastegate actuators or boost leaks. The manual provides diagnosis for these.
Ignition System Considerations:
Spark plug wear, distributor cap and rotor condition (if applicable), ignition coil performance are critical for smooth operation.
Brand Heritage:
Rolls-Royce and Bentley represent the pinnacle of British automotive luxury and engineering. The models covered are from a period where both brands were under the same ownership group (Vickers plc for Rolls-Royce, Bentley was part of the same entity).
Model Evolution Context:
These models represent the evolution of the Silver Shadow/T-Series platform, incorporating modern electronic engine management to improve performance, efficiency, and emissions compared to earlier carbureted or mechanical injection systems.
Production Period:
The 1987-1989 period falls within the latter half of the production run for many of these models, which often spanned well into the 1990s.
