HI my name is Siyuan Chen, This is my first time using Wikipedia

I chose the electric vehicle for my research optic. I strongly believe that it will become the main direction for future automobile companies. Traditional vehicles are the largest consumer of fossil fuels at present, if electric vehicles can be widely promoted and gradually replace traditional vehicle, they will contribute greatly to protecting the environment and saving energy.

Is each fact referenced with an appropriate, reliable reference? If there are unreliable sources, identify them and explain why they are unreliable. I think the source of the citation is very reliable. EX： According to Wikipedia，“In the 21st century, EVs saw a resurgence due to technological developments, and an increased focus on renewable energy. Government incentives to increase adoptions were introduced, including in the United States and the European Union.” The above citation is derived from https://www.energy.gov/articles/fact-sheet-obama-administration-announces-federal-and-private-sector-actions-accelerate （US Department of Energy）

Is everything in the article relevant to the article topic? Is there anything that distracted you? If so, identify it and explain why. All the articles I've been looking for are related to the topic，My article includes the following categories such as the definition of an electric car. The history of the development of electric vehicles. Why are many countries promoting electric cars? The technology of lithium battery. What is the advantage of electric cars?

Is the article neutral? Are there any claims, or frames, that appear heavily biased toward a particular position? I think the article mainly focuses on the promotion of electric vehicles, and tells readers that electric vehicles are environmentally friendly, but omissions the adverse environmental factors in the battery manufacturing process.

Is any information out of date? Is anything missing that could be added? I think electric vehicle is a hot topic, so it keeps updating information on Wikipedia. I looked at the history record and the latest update is in April 20, 2018.

Where does the information come from? Are these neutral sources? If biased, is that bias noted? I think its main literature comes from all kinds of books, University Libraries and the US Department of energy.

V8 engine

The V8 engine is a eight cylinder V configuration engine. The cylinder is mounted on the crankcase. It has eight pistons to drive a common crankshaft. Most engines have a cylinder angle of 90 degrees, but there are also narrow angles, such as 45 degrees and 60 degrees. Its form is very simple. V8 basically is two parallel 4 cylinder engines sharing a common crankshaft. This simple structure makes the engine more balanced and less vibrant. Many American muscle cars use the V8 engine.

Citation： According to Wikipedia “The most prevalent V angle for a V8 is 90°. This configuration features a wide, low engine with optimal firing and vibration characteristics.”

Cessna 162 Skycatcher

Cessna 162 Skycatcher is a light aircraft made in the US, and it has only two seats. It was designed and produced by Cessna between December 2009 and December 2013. This is the latest launch of the general aviation product line of the company. Its purpose is to fly training and personal use.
