Automotive elitists really like to ridicule carburetors. "A barely controlled fuel leak," some of them like to say. Maybe so, but when fuel injection debuted on European cars back in the 1970s, carburetors seemed warm and familiar like Mom's apple pie in the face of three horrifying letters: CIS. CIS means Bosch Continuous Injection System, a fully mechanical.system that operates with high fuel pressure and which requires expensive special tools to set up. As the name implies, the fuel injectors spray continuously. Fuel pressure is regulated mechanically according to air flow into the intake manifold, which is also metered mechanically. Screw up the system and CIS will dump enough fuel into the engine to wash out the bearings in a matter of minutes.
