Nurburgring 28/05/2012, First Contact

Finally, I tried the Nurburgring. It was only 3 Laps for my “dummy start”. I love this track.

Tube de 1 inch pour l’eau passant 2 fois dans le compartiment, admission de diametre 2 inches et d’une longueur de 12 inches par 5 et par 5 (pour 270 HP). Peut etre aussi interessant d’avoir le dessus et dessous creux afin de passer de l’eau et mieux refroidir. Intercooler de voiture de petite taille. On rajouter 2 inch de long tous les 90 HP et on change le diametre de l’entree/sortie en fonction.

Some ideas for low energy and efficient cars

What is a more efficient car ?

A car that has a low cost, is reliable, is light-weight, has good performance and high mpg.

More Lightweight and Secure Cars

  • F=m.a, the smaller the mass the higher the acceleration for a given power.
  • Avoid not needed stuff, there is lot…

More Efficient Motors

Mechanical Devices

  • Turbo charging: reuse energy from exhaust gas to compress inlet air, less pollution and more power. (http://en.wikipedia.org/wiki/Turbo-compound_engine). Difficult to apply on motor bikes, due to so called lag but should work. Water intercoolers help to limit turbo lag due to their size.
  • Multi-Stage turbo charging for diesel: small turbo followed by a bigger one. Given a small displacement motor it is possible to achieve very high power output, 200 BHP/liter is achievable. Water intercoolers are very helpful in such case to limit lag.
  • Compounding: takes kinetic energy from exhaust gas using a turbine and gears reduction to crank-shaft  (http://en.wikipedia.org/wiki/Turbo-compound_engine), about 20 to 25% more torque (and thus power). Can be use on motor bikes, there is no lag as for a turbo.
  • Kinetic Energy Recovery: takes energy when braking to spin quickly a disc, helps to have some amounts of torque for acceleration.  Better power/weight ratio than batteries, that why it is used in Formula 1. (http://en.wikipedia.org/wiki/Regenerative_braking). I think it is also very useful on motor bikes with a tiny hydraulic motor on the front wheel.
  • Variable Compression Ratio: more efficient motor on low and mid range. (http://en.wikipedia.org/wiki/Variable_compression_ratio). For gasoline engine, water injection can be used to  save precious gasoline while achieving more power.
  • Constant Variable Transmission: can replace a whole gearbox and is lighter (http://en.wikipedia.org/wiki/Continuously_variable_transmission)

Electricity

  • Electric water pump: low and mid-range needed coolant flow is bigger than high rpm. Most mechanical water pump are over designed. This is very useful for trucks and heavy duty motors.
  • Alternator/Starter Motor: limits weight and can be used to put additional power on low to mid range revs.
  • Higher voltage: cost saving for copper and save weight.(Power=Voltage.Intensity)
  • Compounding, Kinetic Energy Recovery: can be used to generates electricity, to refill batteries.
  • Thermal Energy from Motor: takes thermal energy and generates electricity, helps to refill batteries.
  • Supercapacitor: a reserve of electric power to smooth power demand on batteries. It allows faster acceleration. (http://en.wikipedia.org/wiki/Supercapacitor)

More efficient cars need more efficient traffic lights control !

Car construction project

I am a car construction enthousiast, and start in 2005 constructing a car.

My Car Specs:

  • hybrid space frame and back-bone chassis (steel RHS and tubes)
  • transversal motor rear wheel drive (1.6 16V Nissan – about 100 BHP)
  • dual wishbones (front)
  • fully adjustable geometry :
    • castor and slip angle.
    • quasi-constant wheel-base under load.
    • adjustable rocker factor.
    • variable height.
    • possibility to go to progressive suspension acting on the geometry (like ProLink, MonoCross, FullFloater…etc…).
    • possibility to modify to 4 directive wheels (such as car races on ice) or like Lotus Elise.

Photos now available:

Sleeping for one year….

  • strengthening (second stage) the main beam (planning done)
  • strengthening (second stage) passenger and driver part (in progress)
  • front suspension (planning done)
  • steering, arm, wheel hubs (planning done, parts to buy)
  • rear part with motor …etc… (done)
  • rear chassis (planning)

Turbo_calc

A small piece of software done after reading “Turbo Chargers” by Hugh MacInnes.The software depends on the FLTK ToolKit (small and easy to build and use).This software is released under the GNU GPL, tested on Linux and Win32 (mingw).

WIN32 Binary

Turbo_calc

Description: Given size of the motor, rpm, air temperature, pressure ratio, efficiency of the turbo and intercooler and pressure drop the software compute CFM, temperature, density …etc…
