Post #2: Fuel Efficiency

       As a part of my goal, I wanted to learn more about fuel efficiency, what factors contribute to good fuel economy, and why does it happen? And I have done research and found, there are multiple key factors involved with fuel efficiency.
     
      The first factor is displacement, Displacement is the volume of air your engine consumes in a single revolution. It is usually measured in litres. The more air your engine moves, the more fuel it consumes. So less Displacement is more fuel efficient. For example, a Yaris has a 4 cylinder 1.5L engine. The 1.5L is the amount of air the engine intakes for each revolution.
      Another key factor is an obvious one, weight makes your engine work harder than usual, and more work for your engine won't be better for your wallet. A smaller sized vehicle won't move the scales that much, but some SUV's and trucks weigh a good 5,000lbs. Basically the heavier a vehicle is, the more power it needs, which means a bigger engine. If the engine doesn't work well with the weight of the vehicle, then it won't save gas as well.
      Those are just 2 of the factors, but there are much more such as: Gearing, Aerodynamics, and etc. But the other factors could be posted up sometime later. Just to keep this post short. I hope you keep reading these blog posts.
