The manual choke pull handle in a 1989 Hyundai Excel. The term "choke" is applied to the carburetor's enrichment device even when it works by a totally different method. Commonly, SU carburettors have "chokes" that work by lowering the fuel jet to a narrower part of the needle. Some others work by introducing an additional fuel route to the ...
A stroke is the action of a piston travelling the full length of its cylinder.In a two-stroke engine, one of the two strokes combines primarily the intake stroke and the combustion stroke, while the other stroke primarily combines the compression stroke and the exhaust stroke, though technically since both ports are exposed during both the combustion and compression strokes, some reversion ...
Animation of a two-stroke engine. A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston (one up and one down movement) in one revolution of the crankshaft in contrast to a four-stroke engine which requires four strokes of the piston in two crankshaft revolutions to complete a power cycle.
(The data below does not seem to include shale oil and other unconventional sources of oil such as tar sands. For instance, North America has over 3 trillion barrels of shale oil reserves, [ citation needed ] and the majority of oil produced in the US is from shale, leading to the paradoxical data below that the US will finish all its oil at ...

Zenith Carburetor Company, American subsidiary of Société du carburateur Zénith. Zenith Carburettor Company (British), used on Austin cars. Also produced the Zenith-Stromberg carburetors.
In a two-stroke engine, the carburetor power valve operates in the opposite manner: in most circumstances the valve allows extra fuel into the engine, then at a certain engine RPM it closes to reduce the fuel entering the engine. This is done in order to extend the engine's maximum RPM, since many two-stroke engines can temporarily achieve ...
The 2.6 RS was a special high-performance fuel-injected 2.6 L; 160.9 cu in (2,637 cc) version. It had a 90 mm × 69 mm (3.54 in × 2.72 in) bore and stroke, and produced 150 PS (110 kW; 148 hp) and 219.5 N⋅m (162 lb⋅ft). The only fuel injected first-generation engine, its sole application was the 1970-1973 Ford Capri RS 2600.
Too much oil pressure can create unnecessary work for the engine and even add air into the system. To ensure that the oil pressure does not exceed the rated maximum, once pressure exceeds a preset limit a spring-loaded pressure relief valve dumps excess pressure either to the suction side of the pump, or directly back to the oil pan or tank.
