Transcript of Motorcycle Movement System

Motorcycle engines are generally classified
by one of three characteristics:
the number of cylinders they possess,
the capacity of their combustion chambers or the
number of strokes in their power cycles. The movement cycle of a motorbike The cycle of a motorbike engine Motorcycle engines In an engine these things occur as part of a cycle. That cycle is basically this -SUCK, SQUEEZE, BURN, and BLOW. The fuel mixture must be brought into the cylinder -SUCK, compressed -SQUEEZE, ignited -BURN, and then expelled from the cylinder -BLOW. All reciprocating engines must go through these steps no matter what the design of the engine (two-stroke, four-stroke, and so on). The consistent trend of
a four stroke engine This is all done in four strokes of the piston.

Four-Strokes. Motorcycle engines work the same way that car engines do. They consist of pistons, a cylinder block and a head, which contains the valve train. The pistons move up and down in the cylinder block, driven by explosions of a fuel-air mixture that has been ignited by a spark. Valves open and close to allow the fuel-air mixture to enter the combustion chamber. As the pistons move up and down, they turn a crankshaft, which transforms the energy from the pistons into rotary motion. The rotational force of the crankshaft is transmitted, via the transmission, to the rear wheel of the motorcycle. What’s the most fuel-efficient mode of
personal powered transport?
Which mode pollutes the least? If you actually look at the size, build, the amount of
fuel used and the distances it usually travels, a motorcycle
easily overlaps a car in fuel-efficiency. Once again, it is all
because of the engine. A Suzuki Across 4 cylinder 250cc motorcycle has around
about 0.125L of displacement, 4,000rpm and around about
1,000rpm/L.Compared to a car, this is much more energy and
fuel-efficient. So how does this all fit in? Fuel > Engine > Pressure from Piston + Spark >Fuel Combusts > Heat + chemical Energy
is Syphoned > CO2 Released + Some Energy
not Gathered + ENERGY MOVES TO GEARS >
Gears Move + Wheels Move >
Motorcycle Moves In summary... Overall, the way the engine is built utilizes the majority of the energy, but there is yet one that can use all of the energy that is emitted. As the chemical energy is harnessed, heat is made and is exerted from the engine with the CO2. This can be quite a waste as the said energy could be harnessed to give more power to the engine, also, some kinetic energy is exerted with the other bi-products.Overall, this mechanism can be improved, but as it is now, is very useful. A motorcycle is more fuel conservative than any non-electric car on the market and also is very versatile in where you can travel on said vehicle. The cycle of a motorcycle
