Fuel pressure gauge - Indicates the supply pressure of fuel to the carburetor (or in the case of a fuel-injected engine, to the fuel controller.) Fuel boost pump switch - Controls the operation of the auxiliary electric fuel pump to provide fuel to the engine before it starts or in case of failure of the engine-powered fuel pump. Some large ...
The oil system used three pumps with a separate 35-litre oil tank. The supercharger was advanced for the era in that it used a barometrically controlled hydraulic clutch (fluid coupling) which allowed the system automatically to compensate for changes in altitude. The DB 605 was supercharged. Pictured, a DB 605A.
A 3-port solenoid-type boost controller A 4-port solenoid-type boost controller (used for a dual-port wastegate). The purpose of a boost controller is to reduce the boost pressure seen by the wastegate's reference port, in order to trick the wastegate into allowing higher boost pressures than it was designed for.
The supercharger is taken from an R-3350 used on the Lockheed EC-121 and the engine is fitted with nitrous oxide injection. Normal rated power of the original stock R-3350 was 2,800 hp (2,100 kW) at 2,600 rpm and 45 inHg (150 kPa) of manifold pressure.
An Eaton M62 Roots-type supercharger is visible at the front of this Ecotec LSJ engine in a 2006 Saturn Ion Red Line.. The Roots-type blower is simple and widely used. It can be more effective than alternative superchargers at developing positive intake manifold pressure (i.e., above atmospheric pressure) at low engine speeds, making it a popular choice for passenger automobile applications.
Positive displacement superchargers deliver an almost constant level of boost pressure increase at all engine speeds, while dynamic superchargers cause the boost pressure to rise exponentially with engine speed (above a certain threshold). [4] Another family of supercharger, albeit rarely used, is the pressure wave supercharger.
Turbochargers and superchargers are both engine-driven air compressors (exhaust-driven or mechanically driven, respectively) and provide varying levels of boost according to engine rpm, load etc. [4] Quite often there is a power band within a given range of available boost pressure and it is an aid to performance driving to be aware of when ...
The British measured boost pressure as lbf/in 2 (psi). The normal atmospheric pressure at sea level is 14.7 psi, so a reading of +6 means that the air/fuel mix is being compressed by a supercharger blower to 20.7 psi before entering the engine; +25 means that the air/fuel mix is now being compressed to 39.7 psi.
