   en.wikipedia.org/wiki/Rochester_Ramjet

   Rochester Ramjet system installed on a 1957 Chevrolet 210. The Rochester Ramjet is an automotive fuel injection system developed by the Rochester Products Division of General Motors and first offered as a high-performance option on the Corvette and GM passenger cars in 1957.

3. Idle air control actuator - Wikipedia

   en.wikipedia.org/wiki/Idle_air_control_actuator

   An idle air control actuator or idle air control valve (IAC actuator/valve) is a device commonly used in fuel-injected vehicles to control the engine's idling rotational speed . [1] In carburetted vehicles a similar device known as an idle speed control actuator is used.

4. Engine control unit - Wikipedia

   Fuel pressure regulator; Rev limiter; Wastegate control and anti-lag; Theft prevention by blocking ignition, in response to input from an immobiliser; In a camless piston engine (an experimental design not currently used in any production vehicles), the ECU has continuous control of when each of the intake and exhaust valves are opened and by ...

5. MAP sensor - Wikipedia

   en.wikipedia.org/wiki/MAP_sensor

   Thus, a MAP sensor will always read 100 kPa more than a boost sensor measuring the same conditions. A MAP sensor will never display a negative reading because it is measuring absolute pressure, where zero is the total absence of pressure. Vacuum is measured as a negative pressure relative to normal atmospheric pressure. Vacuum-Boost sensors can ...

6. Vapor lock - Wikipedia

   en.wikipedia.org/wiki/Vapor_lock

   Vapor lock is a problem caused by liquid fuel changing state to vapor while still in the fuel delivery system of gasoline-fueled internal combustion engines.This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling.

7. Pressure regulator - Wikipedia

   en.wikipedia.org/wiki/Pressure_regulator

   A typical nominal regulated gauge pressure from a medical oxygen regulator is 3.4 bars (50 psi), for an absolute pressure of approximately 4.4 bar and a pressure ratio of about 4.4 without back pressure, so they will have choked flow in the metering orifices for a downstream (outlet) pressure of up to about 2.3 bar absolute.
