Upto to which point this air can be reduced. (I mean in the AFR ratio like 10: 1 , 8: 1) ? Realize, if you were to open the butterflies and nothing else were to occur (no additional fuel), you'd be going lean (higher air to fuel ratio ... 16:1, 18:1, and much higher). The computer or carburetor in most vehicles will control the amount of fuel ...

Let me see if I can clear some of this up for you. The stoichiometric ratio (AFR) for the petrol is 14.7 : 1 right? This is correct, and it's important to understand the concept of stoichiometric ratio. It means that when the fuel and air are burned, they must be in this ratio if you want them to combine completely, with nothing left over (well, none of ...

Physics suggests that its easier to pull vs push, but based on specific conditions and assumptions. Depends on the vector of the external force of the push / pull and where and how it acts on an object. I believe in a motorized wheeled vehicle, its not nearly as significant, especially since the rotational torques are being transferred to the ground at ...

Engine Position does play a part but its not what you think, RWD cars have the power transmitted to the rear wheels and has to make a 90 degree turn in the differential, resulting some power loss (fuel efficiency). FWD cars beat this by turning the engine sideways, now the axles turn parallel to the engine, no redirection of power is needed. The net result ...
