1981 Volvo DL, GL and GLT pg. 55 Servicing II Engine Fuel System CI system The B21F engine is provided with a fuel injection system called the CI system (Continuous Injection). Fuel injectors are open and inject fuel as long as the engine is operating. This system has few moving parts, is reliable and meets the exhaust emission standards at maximum efficiency. Air supplied to the engine is continuously measured and determines the amount of fuel injected. The air flow is regulated by the throttle valve. The air flow sensor and the fuel distributor are integrally built as a single unit. A lever is actuated by the air flow to produce continuous fuel distribution. pg. 56 Servicing Special instructions for work on the fuel injection system Extreme cleanliness is essential when working on the injection system.
