2. Vapor lock - Wikipedia

   en.wikipedia.org/wiki/Vapor_lock

   Vapor lock was far more common in older gasoline-fuel systems incorporating a low-pressure mechanical fuel pump driven by the engine, located in the engine compartment and feeding a carburetor. Such pumps were typically located higher than the fuel tank, were directly heated by the engine and fed fuel directly to the float bowl inside the ...

3. Dieseling - Wikipedia

   en.wikipedia.org/wiki/Dieseling

   Some carbureted engines have low-pressure fuel pumps: they are typically designed only to overcome a loss of suction in the fuel line near the engine due to fuel evaporation in hot weather, to supply sufficient fuel to maintain stoichiometric combustion under heavy load with wide-open throttle, or a combination of the two. Fuel demand is low at ...

4. Fuel pump - Wikipedia

   en.wikipedia.org/wiki/Fuel_pump

   Some engines do not use any fuel pump at all. A low-pressure fuel supply used by a carbureted engine can be achieved through a gravity feed system, i.e. by simply mounting the tank higher than the carburetor. This method is commonly used in carbureted motorcycles, where the tank is usually directly above the engine.

5. Fuel starvation - Wikipedia

   en.wikipedia.org/wiki/Fuel_starvation

   British Airways Flight 38 crash-landed at London Heathrow in 2008 after its fuel lines became clogged with ice crystals.. In an internal combustion engine, fuel starvation is the failure of the fuel system to supply sufficient fuel to allow the engine to run properly, for example due to blockage, vapor lock, contamination by water, malfunction of the fuel pump or incorrect operation, leading ...

6. Oil pump (internal combustion engine) - Wikipedia

   en.wikipedia.org/wiki/Oil_pump_(internal...

   Indications of low oil pressure may be that the warning light is on, a low pressure reading on the gauge, or clattering/clinking noises from the engine. Low oil pressure is a problem that must be addressed immediately to prevent serious damage. The leading cause of low oil pressure in an engine is wear on the engine's vital parts.

7. Hydrolock - Wikipedia

   en.wikipedia.org/wiki/Hydrolock

   During a rollover, or when a wave washes over the craft, its engine can hydrolock, though severe damage is rare due to the special air intakes and low rotating inertia of small marine engines. Inboard marine engines have a different vulnerability as these often have their cooling water mixed with the exhaust gases in the header to quiet the engine.

8. Diesel engine - Wikipedia

   en.wikipedia.org/wiki/Diesel_engine

   1952 Shell Oil film showing the development of the diesel engine from 1877. The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine).

9. Unit injector - Wikipedia

   en.wikipedia.org/wiki/Unit_injector

   Also Cummins PT (pressure-time) is a form of unit injection where the fuel injectors are on a common rail fed by a low-pressure pump and the injectors are actuated by a third lobe on the camshaft. The pressure determines how much fuel the injectors get and the time is determined by the cam.
