Dit is wellicht interessant: http://www.facebook....314274645361492 Another advantage of the TSI engine is better performance in high altitude areas. It’s a common known fact that a naturally aspirated engine (no turbo) loses between 10% - 17% of its quoted power in high altitude conditions. This is especially applicable to vehicles sold in the Highveld area (e.g. Gauteng) where altitudes range from 1,500m to 2,100m above sea level. The air is thinner at high altitudes than at low altitudes, therefore the airflow into the engine is also less dense than usual, and less effective at burning fuel. This means less power and torque. Volkswagen’s more compact TSI engines will always outperform its naturally aspirated competitors by pumping compressed air into the engine making more air available to burn up the fuel. En nog specialer, de TSI motor heeft zelfs een omgevingsdruk sensor aan boord! http://www.volkspage.net/technik/ssp/ssp/SSP_359.pdf zie blz. 32 + 33. It measures the pressure and the temperature in the intake manifold Signal use The engine control unit calculates the air mass drawn in from the signals and engine speed
