Over boosting an engine fitted with a turbo-charger is prevented by the installation of:

• A. An automatic boost control unit.
• B. A manifold pressure gauge.
• C. A waste gate pressure controller.
• D. A suck in flap.

Answer: (B)

The installation of a manifold pressure gauge plays a crucial role in monitoring the pressure within the intake manifold of a turbocharged engine. By providing real-time data on the boost pressure, the gauge helps the operator or the engine management system to assess whether the engine is operating within safe limits. If the pressure exceeds a certain threshold indicative of overboosting, corrective measures can be implemented to prevent potential engine damage. Utilizing this gauge enables a clearer understanding of how the engine's boost levels correspond to its operational conditions, allowing for better performance tuning and safety measures. Although other devices can control or regulate boost pressure, such as an automatic boost control unit or wastegate pressure controller, the manifold pressure gauge primarily serves as the observational tool that alerts users to any potentially hazardous conditions due to excessive boost.
