The
information in this article was adapted from a press release from the BMW group
explaining their concept of Efficiency Dynamics. This concept, created by BMW, addresses
my argument that I am trying to make directly. BMW has always been about
creating the ultimate driving machine, which simply put is creating a car that
is exhilarating to drive all while giving the consumer many benefits. These
benefits include better fuel economy and fewer amounts of carbon emissions
being produced by the engines aiding to a greener planet. In recent years what
has allowed BMW to achieve their goal, which is creating “The Ultimate Driving
Machine,” is by creating a large fleet of cars utilizing high performance
derived engines paired with single or dual turbochargers. The utilization of
turbo chargers has allowed for BMW to decrease displacement size of the engine,
making it less thirsty, which in turn allows the car to be lighter. This is
achieved by using more magnesium and aluminum components, which are stronger
and lighter than conventional steel, for construction. This ultimately leads to
the car being lighter and stronger and cleaner running.

This
article gives a good, yet fairly basic, description of turbochargers and how
they work in the car. The article states some key advantages and disadvantages
of this type of forced induction; however, it does mention something that is
very crucial to the argument that I am trying to make. This concept, as
mentioned by the author, is what is known as “free power.” Free power does not
mean that the car be powered for no cost to the consumer; however, the car can
be aided by a source of power that would have simply had just been expelled completely
in a naturally aspirated car. The turbocharger takes exhaust fumes and recycles
them to cooler, more condensed air as it is pushed through the turbine of the turbo
and into the cylinder heads to create the explosion to power the car. This
cooler, more condensed air provides a better punch than normal atmospheric
pressure air, which is employed by naturally aspirated engines. This extra
punch provided by the turbo allows for the engine to be lighter, which by a
series of engineering chain of events, allows for the entire car to be lighter.
This means the car can have a better focus on improved fuel economy and reliability
to cost less to the environment and consumer respectively.
James,
ReplyDeleteYour annotations show why you are using the sources and not just summarizing, which is good. My only comment is that you can revise the annotations for language. In your annotation, there is a lot of passive voice that leads to awkward constructions.
Example, last sentence of the first annotation: "This ultimately leads to the car being lighter, and stronger, and clean running"
You can rewrite this as "This ultimately leads to a lighter, stronger, and cleaner car."
There are many sentences like this one, where you use "being" as a verb, which makes your sentences hard to read.
