The turbocharger...how it works

..it never compresses the exhaust gases back into the burning chamber, good way to understand how the turbo charger (turbo compressor) works...see the video

Stopping a car example with chart

In this post I want to give you an example of what hapens when we press the brake pedal, so I uploaded another chart...

      -the lowest curve (dark blue) expresses braking maneuvre with the ABS on, and on a good grip surface - from 230km/h to a full stop in @ 240 meters;

      -the second one (purple) - without ABS - 230km/h to a full stop in @ 300 meters;

      -third (yellow) - on wet tarmac - 230km/h to a full stop in @ 360 meters;

      - 4th (light blue) - on ice - 230km/h to a full stop in @ 750 meters;

       The braking distance is given by

                          

        V-speed;
        g-gravitational acceleration;(9.81 m/s^2)
        fi-grip coefficient. 0<fi<1 as next

And to think that in Germany you can drink a couple of beers and then run on highways with 300km/h legally...

Nm vs HP

Not everybody understands the difference between torque and horsepower, the most important thing to know is that the first makes the second like this...

Power[HP]=torque[Nm] x speed[rpm] x1/7021.55

this means that power is direct related to torque but they are not one and the same. 

all data available trough e-mail, leave a comment,and after that if you need translations or anything I am at your disposal,

thanks!

Dynamics...It's always the right way!

Everything moves, solid objects or fluids, sound or light, and every  move can be precisely described with the help of a mathematical expression. In the automotive industry like any other, using this science facts,  manufacturers design the experiments so that they don't have to physically test every choice they have in the process of developing  a product, wich would be very expensive in therms of time and money. Think about testing every type of fluid in the development process of shock absorbers!

I started this blog because cars are my passion, and I get  to read false articles about cars almost every day...

11 most important things when buying a second-hand vehicle

In many cases buying a second-hand car is the best option for many drivers for a lot of reasons:

• First of all, there are tons of second-hand cars alot cheaper (30-50% of their out of factory value) just 4-5 years old that behave and have the characteristics of the new car for the 3rd of a price;

• There are cars that aren't sold as new anymore but may have a better design than the cars that are at the time in the new car market;

• Of course some of them may be purchased as an investment since some specific models are suspected to become wanted models in the next decades, just like the 1962 Ferrari GTO250 did;

...and many more

...now the most important 11 things when buying a second-hand vehicle are:

When you go for a testdrive:

1.  when buying a second-hand vehicle you have to make sure that the steering wheel is not rotating just by himself  when driving 10-30 mph, this means that the wheels are not round anymore;
2. when braking  the vehicle must decelerate smoothly without frequent (oscilations) peaks of deceleration;
3. the oil shouldn't be fresh, this can happens when the seller wants to hide that he is selling a vehicle with an almost broken engine;
4. if the vehicle has rust is not always a problem, the problem is when the parts that you can't change are rusted, parts like chasis, luggage compartment, under the floor carpets, on the side skirts- these are places that you really don't want to have rust;
5. you should check every lock to make sure that they are all in a good state;
6. you have to estimate the mileage of the vehicle, for example a 50 000 mile vehicle should NOT have it's seat's material  broken, scratched  interior plastics...etc.
7. if the vehicle has a visible or known problem you can compare it with other vehicles and you can look for how much money you can replace the problematic part.
