A cutaway view of the intake of the original Fordson tractor (including the intake manifold, vaporizer, carburetor, and fuel lines).. A petrol-paraffin engine differs from a single-fuel petrol engine in that two independent fuel tanks containing petrol and paraffin (respectively) are required, but both fuels may be supplied through the same carburetor or fuel injection system.
A petrol engine (gasoline engine in American and Canadian English) is an internal combustion engine designed to run on petrol (gasoline). Petrol engines can often be adapted to also run on fuels such as liquefied petroleum gas and ethanol blends (such as E10 and E85). They may be designed to run on petrol with a higher octane rating, as sold at ...
These may involve the choice of major engine components or systems, such as the use of dry sump lubrication system over a wet sump system. Alternately, this can be effected through substitution of minor components available as aftermarket modifications, such as exchanging a directly engine-driven fan for one equipped with a fan clutch or an ...
The ignition system of an internal combustion engines depends on the type of engine and the fuel used. Petrol engines are typically ignited by a precisely timed spark, and diesel engines by compression heating. Historically, outside flame and hot-tube systems were used, see hot bulb engine.
Its high specific power, high fuel efficiency and low exhaust pollution have made it a promising technology. As a compression-ignition engine, the fuel mixture ignites due to the increase in temperature that occurs with compression rather than a spark from a spark plug. [5] A PPC engine injects and premixes a charge during the compression stroke.
Although direct injection has only become commonly used in gasoline engines since 2000, diesel engines have used fuel directly injected into the combustion chamber (or a pre-combustion chamber) since the first successful prototype in 1894. An early prototype of a GDI engine was built in Germany in 1916 for the Junkers airplane. The engine was ...
Also in 1957, General Motors introduced the Rochester Ramjet option, consisting of a fuel injection system for the V8 engine in the Chevrolet Corvette. During the 1960s, fuel injection systems were also produced by Hilborn, [46] SPICA [47] and Kugelfischer. Up until this time, the fuel injection systems had used a mechanical control system.
With the help of geometrically variable turbo-charging system (albeit more maintenance) this also increases the engines' torque at low engine speeds (1,200–1,800 rpm). Low speed diesel engines like the MAN S80ME-C7 have achieved an overall energy conversion efficiency of 54.4%, which is the highest conversion of fuel into power by any single ...
