Getting Around Green: Consider A Motorcycle

Our vehicles emit a lot of pollutants that are damaging for the environment, and the extent of pollution depends upon the type of vehicle.Cars are our everyday vehicles, but when it comes to a combination of fun and efficiency a motorcycle is the way to go! If you think you can handle a bike then you should go for it and if you just want to be a little greener here are some benefits of this vehicle:

Green advantages of motorcycles

1. They emit less carbon dioxide

Motorcycles consume less fuel than cars, which means their production of carbon dioxide is also less. As the importance given to fuel efficiency and carbon dioxide emissions increases with time, motorcycles provide a greener option. They also take less space on the road, reducing the congestion and overall automobile emissions.

2. Leaner manufacturing and lower embodied energy

Motorcycles require fewer infrastructures to be manufactured compared to cars. The embodied energy of a motorcycle, just from its much smaller mass, is much lower than a car, all else being equal. In addition, if you consider the contribution of building separate lanes for motorcycles and cars, there’s a huge difference in production of greenhouse gases. If separate lanes are constructed for motorcycles as we have roads for cars, they would emit four times less greenhouse gases to maintain and build.

3. Consume less rare earths

Rare earths are being consumed at a fast pace, and the demand is increasing from different industries, including automotive. The average Prius is carrying around about 10 pounds of lanthanum as part of the battery. A motorcycle uses little to none in manufacturing because battery powered bikes are not widely produced and gas powered bikes are so efficient.

4. Manufacturers are using catalytic converters

Motorcycle manufacturers have realized the role they have to play for attaining a greener environment and are putting catalytic converters in the vehicle, which does a great job at reducing the pollution emitted. They prevent harmful elements from the motorcycle’s exhaust from being released into the air, and converts nitrogen oxide into nitrogen and oxygen before the release.Although these converters does not operate at 100% reduction they are pretty close and factor that into the already low-emission engines of motorcycles and you have a very green ride.

5. They’ve smaller engines

The engine of any vehicle is its more prized asset, and as motorcycles have a smaller engine than other vehicles, it uses less energy and fuel. Engine parts on motorcycles are designed to be incredibly efficient because there is no space for wasted parts. From the carburetor to the o-ring a motorcycle engine can be viewed as the pinnacle of individual transportation efficiency.

6. They are awesome! 

A main reason why people own motorcycles is because they are awesome! Not only are they incredibly fun, but its hard not to look cool on a motorcycle too! The future of motorcycles could become even more green thanks to solar technology on bikes! Right now you can get a super fun and efficient bike but imagine having a solar powered personal transportation vehicle, the future is bright!

Apart from all the environmental benefits of considering a motorcycle, there are other advantages as well. They are more affordable in terms of traveling while spending less on fuel. Even existing car owners can take advantage of a motorcycle, keeping their cars for when they need more space, but using the bike for getting around, which will lead to increased savings and fun.

    1. Changing the design of the existing cylinder head engine.
    Result – 2x magnification power.
    Reducing the number of parts, weight and size of the cylinder head and the engine.
    2. Manufacturing of the new engine.
    Torque 6100 Nm at 100 r / min.
    Power 5000 kwt 10000 r / min.
    Engine weight – 57 kg.
    Maximum speed – 20 000 rev / min

    Deficiencies and disadvantages of piston engines

    1. A full cycle of a four-stroke piston engine consists of two full turns of the crankshaft, of which only one half of one turn comprises the power stroke (the only part of the whole cycle that produces any useful work). The other one and a half turns of the crankshaft the piston engine functions as a compressor.

    2. More than half of the thermal energy released in the combustion process inside the cylinder is wasted in the beginning of the power stroke. Maximum pressure (Pmax) in the combustion chamber is achieved at the beginning of the power stroke when the combustion takes place (which is right after spark ignition in the gasoline engine, or right after fuel injection in a diesel engine).

    At this point, the piston is located at the upper dead center (UDC, see the drawing), with the lever (R) responsible for the creation of the moment of rotation (M) being equal to zero. And since R = 0, it also follows that the moment, M = Pmax x R, is also equal to 0.

    Half a power stroke later (after 90° turn of the crankshaft), the cylinder pressure drops from its maximal value down to its intermediate point (Pmid, somewhere b/w Pmax and atmospheric pressure). At this point, lever R is at its maximum, (Rmax) and, therefore, M = Pmid x Rmax.

    90° to 180° is what remains of the power stroke, during which both the pressure (P) and the lever (R) drop, providing little, if any, useful work. Much of the released thermal energy is lost on heating the piston and cylinder walls.

    3. Piston engines achieve their maximal rotational moment (M) only at midrange of the RPM ranges. Reasons for this are many-fold:

    (a) Insufficient filling up of the cylinder with air at low RPM;
    (b) Insufficient filling up of the cylinder with air at high RPM;
    (c) Inertial loading of valve mechanisms and resultant loss of kinematic linkage due to the inability of valve springs to close valves fast enough at higher RPM.

    As a result of the above, fuel consumption is high, engines run hot, air pollution is high, and much power is lost.

    Above-mentioned peculiarities of piston engines require the use of gearbox/transmission, starter, etc. The Roots Rotary Engine (RRE) design being offered should have none of the above disadvantages or deficiencies. It requires neither a crankshaft nor a camshaft, nor pistons, valves, intake manifold, transmission/gearbox, etc. Read our patent application at US PTO: Internal combustion engine with direct air injection, or see it at any other patent search.
