Performance and economy were compared between the fuel injected and carbureted versions. Emission measurements of CO, CO2, and hydrocarbon were made in road tests by proportional sampling and through the California Cycle by continuous nondispersive infra red instrumentation. 展开 ...
The DISI engine has some key future development potential vs. PFI alternatives. As the fuel is injected directly into the piston chamber just prior to spark (charge cooling effect) the DISI has reduced knock tendency, an enabler for compression ratio increase with associated increase in cycle effi...
as quite a few casual riders and even professional racers still prefer the old-school feel and sound of these engines. This is especially evident in enduro racing, where KTM’s own Manuel Lettenbichler won theon a fuel-injected two-stroke. At the end of the day, the Austrian manufacturer ...
(2005) conducted experiments in a single cylinder carbureted two-wheeler engine, in which methanol (M20) was injected using port fuel injection (PFI) technique and they compared its performance with electronic fuel injection (EFI) system. They reported that engine hardware of the EFI system ...

The engine was controlled by an ECU featuring a closed-loop feedback to adjust the injected fuel amount to keep the air/fuel ratio constant. In addition to the neat fuels, gasoline–alcohol blends were prepared with either isobutanol or 1-butanol in concentrations of 30, 50, and 85 vol.%...
STA-BIL® brand is safe to use in both fuel injected and carbureted engines, and will not damage catalytic converters or oxygen sensors. STA-BIL® Fuel Stabilizer prevents the formation of gums and varnish that can clog fuel injectors, and actually contains a fuel injector cleaner to further...
[24] emphasized the need to consider validation under non-premixed flames for GDI engines as the fuel is directly injected into the combustion chamber. Along with this view, Bieleveld et al. [70] experimented and modelled the combustion characteristics of gasoline surrogates and commercial fuels ...
