What's the difference between these cooler type? Pro and cons?

Both are the same thing...the only difference is the position. If the engine has only a single turbocharger then it's always only one intercooler.
Tsi engines uses their radiator as their intercooler too. Correct me if I'm wrong. -------------------- 2003: Dad's Ford Laser 1.6 2004: Dad's Toyota Vios 1.5 2005: Suzuki Swift 1.5 2008: Mitsubishi Colt Version R 1.5 |

In the industry, it means alot in terms of energy used and heat transfer.
For simple single stage turbo charged engine, it's almost the same as cooling down heated compressed air before entering engine for combustion. |

Before or after entering engine for combustion.

Simple Diagram with layman explanation of intercooler function
- When air is compressed by the compressor of the turbo, it get real hot! Don't ask me why, it's physics! - If Hot air goes directly into the engine it's not optimum, Bcos hot air expand and the amount of air into the engine will not be optimum - To get the most out of compressed air, the hot air is cooled by the intercooler to normal temperature, the compress air contracts when cooler. - So more air can be pushed and compress before it reaches the engine...obtaining optimum compressed air into the engine for combustion.  - After conbustion, exhaust release, spins the turbine fins, which in turn spins the compressor to suck in more air. - Spinning controlled by wastegate..which controls the pressure (boost) - The cycle continues......The marvels of force induction...

QUOTE (5936 @ Aug 12 2012, 11:09 PM)  Before or after entering engine for combustion. hmmm. never heard of after cooler before. if the point is to cool air leaving the engine i.e. after, then it really is pointless right?

Aftercooler was used for multi-stage supercharging. Not common anymore. All cooling of air are before entering engine, otherwise it does not make sense.

Ok my mistake.
Gd you that you single out. Thank you. After cooler is to cool the heated compressed air AFTER leaving Turbo Charger but BEFORE entering engine. |

Anyone got a similar schematic like the above for a VW 1.4 TSI engine?
Really interest to know the mechanics behind the super/turbo chargers -------------------- 2003: Dad's Ford Laser 1.6 2004: Dad's Toyota Vios 1.5 2005: Suzuki Swift 1.5 2008: Mitsubishi Colt Version R 1.5 |

Really interest to know the mechanics behind the super/turbo chargers Friend, you may want to visit http://www.youtube.com/watch?v=20qqavckWdw to see a video on this. Very well illustrated. Supercharging is at lower rev provides max torque which at higher speed power demand, the electronics switches a sort of valve such that the turbocharging kicks in and takes over. No feeling of turbo lags. This way provides very smooth acceleration. Sorry cannot find any schematics, only understand the concept. |
