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.
Since the electric pump does not require mechanical power from the engine, it is feasible to locate the pump anywhere between the engine and the fuel tank. The reasons that the fuel pump is typically located in the fuel tank are: By submerging the pump in fuel at the bottom of the tank, the pump is cooled by the surrounding fuel
A gasoline pump or fuel dispenser is a machine at a filling station that is used to pump gasoline (petrol), diesel, or other types of liquid fuel into vehicles. Gasoline pumps are also known as bowsers or petrol bowsers (in Australia and South Africa ), [ 2 ] [ 3 ] petrol pumps (in Commonwealth countries), or gas pumps (in North America ).
The air and fuel are mixed only inside the combustion chamber. Therefore, only air is sucked into the engine during the intake stroke. The injection scheme is always intermittent (either sequential or cylinder-individual). This can be done either with a blast of air [4] or hydraulically, with the latter method being more common in automotive ...
The system uses tubes with poppet valves from a central injector to spray fuel at each intake port rather than the central throttle body [citation needed]. Fuel pressure is similar to a single-point injection system. CPFI (used from 1992 to 1995) is a batch-fire system, while CSFI (from 1996) is a sequential system. [9]
When the throttle is opened (in a car, the accelerator pedal is depressed), ambient air is free to fill the intake manifold, increasing the pressure (filling the vacuum). A carburetor or fuel injection system adds fuel to the airflow in the correct proportion, providing energy to the engine. When the throttle is opened all the way, the engine's ...
Fuel-management systems are used to maintain, control and monitor fuel consumption and stock in any type of industry that uses transport, including rail, road, water and air, as a means of business. Fuel-management systems are designed to effectively measure and manage the use of fuel within the transportation and construction industries.
Intermittent faults are notoriously difficult to identify and repair ("troubleshoot") because each individual factor does not create the problem alone, so the factors can only be identified while the malfunction is actually occurring. The person capable of identifying and solving the problem is seldom the usual operator.
