  what r the contend present in the fuel

  Fuel mainly contains water which burns 👀 . I just invented inflammable water 😨 Want to know more?
  
  P.S: We cannot read your mind. Please post your query in detail. ☕

  Depends on the type of fuel but you haven't mentioned any.😕

  liquid fuel

  In case of liquid fuel rockets it can be a single component like liquid Hydrogen or can be a mixture of hydrocarbons like in petrol.
  This power point presentation from IIT Delhi may help:

  sir ,what are the content we want for a good burn ,and what are the content we eject from fuel
• 

  Ramani Aswath

  Deppends on the fuel. If hydrocarbons the emissions are carbon dioxide and water. There can be some nitrogen compounds as air is used for oxidation.
  If hydrogen only water is the exhaust gas.
  Almost all petroleum products will have a fuel value about 11000KCal/Kg

  sir , what mean fuel value?.
  if hydrogen will increase the efficiency of the fuel mean why we are seprate the hydrogen from water and mix the fuel.
  what are the cotent have ability to increase the fuel combustion at which percentage

  My mistake. I meant calorific value, that is the amount of heat liberated wheen 1 kg of the fuel is completely burnt.
  Hydrogen has one of the highest calorific values at 34000K Cals/Kg. It is not possible to mix hydrogen into other fuels unless they are gaseous fuels.

  Visit the mechanical and automobile engineering thread. There are many posts about the ICE there. You can visit here as well: #-Link-Snipped-#

  what is
  NANO IC ENGINE ,and its principle and how it is work
• 

  Ramani Aswath

  The only miniature IC engine that I have seen was a tiny engine used to power propeller model air planes almost 55 years back. They were essentially the same kind of engines now used on regular vehicles.

  sir, it is possiple to use DC series motor in elctrical vehicle,because the main disadvantage in
  electrical vehicle is speed,but DC series motor have high starting torque so we easily attain high speed

  Speed and torque are not necessarily related. However, for a given power the two are inversely proportional, which means that if you are using a high torque, the RPM will be necessarily low.

  judging from your posts you need to make a vehicle for a obstacle race or something. am i right??
• 

  Jayakumar.j

  yes

  prashpan

  when is the competition??
  keep it simple. use motors and batteries.

  Talk to guys who have participated in last years competition and find out the optimum motor which give you both speed and torque , all the best.
