    Engine throttle/resistance question

    Crysta1c1ear, Yes, this is the way I have been modeling it thusfar, with OutputTorque = Accelerator*GrossTorque(RPM)-Losses(RPM) I assume then that the loss is also a function of the engine speed? I also assume that the losses increase with RPM value, although not by much? I have made the...

    Engine throttle/resistance question

    CrystalClear: First of all, thanx for your post. Yes, I do know about torque or power tables, and that is how I would prefer to model the car/engine. I also have some equations that would build you a torque table if you only have the max power and/or torque at specified rpm values, and no, they...

    Engine throttle/resistance question

    Just one more question: If you guys would recommend a good book on internal combustion engine dynamics, what would it be? The books I have don't really go into engines all that much, and mainly discusses tyres, suspensions, and aerodynamics. Thanx for all your help, you guys have been really...

    Transistors

    If you want a good book on transistors, check out CMOS Digital Intergrated Circuits - Analysis and Design 3rd ed.(Kang & Lebeblici or Lebleblici or something). There are many cross-sectional drawings of transistors inside, as well as descriptions on the entire manufacture process of transistors.

    Engine throttle/resistance question

    Define "torque available at the engine at idle": The torque finally delivered to the clutch, after all the internal losses have been accounted for. The final output delivered to the transmission. The car is in neutral (hence idling), thus the transmission isn't even connected to the engine. The...

    Engine throttle/resistance question

    Redline, I would like to have several C++ classes that, in the end, describe a car in terms of engine, suspension, wheels/tyres, and steering. Obviously it’s going to take a fairly large amount of work just to get all the information about a specific type of car read in. Eventually, you're...

    Engine throttle/resistance question

    Ok, thanks for all your replies. It has helped quite a bit. Just to make certain that I understand exactly what you are trying to say: First of all, there are too many factors to take into consideration than to just model an engine of a particular car from some information on a website giving...

    Engine throttle/resistance question

    I have been given the job of creating a dynamic car model in software at the company I work for. Being a computer engineer, it has been quite an effort for me to get to know cars and the dynamics thereof. As guidelines, I have the following three books to help me: Fundamentals of Vehicle...

    Hardware Interfacing thru C..

    Opening a serial port is done in a very illogical way: you have to make a call to CreateFile(), ReadFile(), and WriteFile() functions with the COM port specified as a string value, i.e. "COM1" or "COM2", etc. You can find good code examples on how to do this on www.codeproject.com. I think it...
