The purpose of the experiment was to determine whether motorcycles or cars produce and contribute a larger portion to the environment. Based on the graphs plotted clearly it is shown that motorcycles have the larger contribution towards air pollution to the environment compared to cars. The difference between the two types of vehicles are also significant. But why? Logically motorcycles are generally more fuel efficient than cars, they burn less gas and thus they must be better for the environment.

The primary sole reason on why cars won this battle when competing with motorcycles are simple. This is because cars have a tighter and stricter regulation. This can be backed up by the fact that since the mid 1970’s the federal standards have been raised and closely monitored on the automobiles for reducing the hydrocarbons and smog causing tailpipes. The regulations were tightly monitored at a steady pace through out almost 50 years. Manufacturers have been putting catalytic converters and sensors to improve and enhance the ability to control their emission but sadly it is just for cars. Motorcycles however have not been equipped with those catalytic convertors up until 2000’s although they are often too big, too heavy or too hot. Therefore, it shows how far that they are bias on one side (cars) and making drastic improvements yearly and how difficult it is to do the same thing with motorcycles as it was just started to be taken to account plus with the tight room that if proceed that can cause incremental cost doubled the price of bikes.

Other than that, the reason for the results is that motorbikes have incomplete combustion of fuel therefore giving a sharp rise in emission. This is because the fuel does not get enough time to vaporize and mix with air, leading to carbon particles growing and aggregating to form soot as a result from smaller engines compared to cars and shorter contact time in the engine.

In conclusion, it can be said that cars have fewer harmful emission than motorcycles as all the required hoses, canisters and catalytic converters fit relatively easily and snugged underneath a car’s hood, despite on a motorcycle. It is also dangerous to install them as it will add cost and weight whereby also generates a lot of heat which is dangerous and uncomfortable to the riders. Thus, making the regulations for motorcycle more lenient and as a result motorcycles emitting more pollutants than cars.
