E85, a mixture of 85% ethanol and ~15% gasoline, is generally the highest ethanol fuel mixture found in the United States and several European countries, particularly in Sweden, as this blend is the standard fuel for flexible-fuel vehicles. This mixture has an octane rating of 108, however, the Ethanol molecule also carries with it an oxygen ...
A fuel gas-powered scooter is a scooter powered by fuel gas. Fuel gases include such fuels such as liquefied petroleum gas (LPG), compressed natural gas (CNG), biogas and hydrogen ( HICE ). Hydrogen ( hydrogen internal combustion ) use in two-wheelers has only recently being started to be looked into, mainly by developing countries, to decrease ...
In motorcycles and cars, the fuel reserve setting indicates that the level of fuel in the tank is low. In cars and most modern motorcycles this quantity (the reserve) is automatically available. Older motorcycles have a manual fuel tap or petcock. When the main fuel is exhausted, the motor will start sputtering, prompting the rider to change ...
A high-octane-rated fuel, such as liquefied petroleum gas (LPG), has an overall lower power output at the typical 10:1 compression ratio of an engine design optimized for gasoline fuel. An engine tuned for LPG fuel via higher compression ratios (typically 12:1) improves the power output.
The higher the octane rating, the more resistant the fuel is to autoignition under high pressures, which allows for a higher compression ratio. Engines with a higher compression ratio, commonly used in race cars and high-performance regular-production automobiles, can produce more power; however, such engines require a higher octane fuel.
Lean-burn gas engines are almost always turbocharged, resulting in high power and torque figures not achievable with stoichiometric engines due to high combustion temperatures. Heavy duty gas engines may employ precombustion chambers in the cylinder head. A lean gas and air mixture is first highly compressed in the main chamber by the piston.
Sport bikes are road bikes that emphasize top speed, acceleration, braking, handling and grip, [3] [5] [25] [26] typically at the expense of comfort and fuel economy in comparison to other motorcycle types. [6] [9] Sport bikes have comparatively high performance engines supported within a lightweight frame.
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 petrol stations. Most petrol engines use spark ignition, unlike diesel engines which run on diesel fuel and
