    Internal combustion engine, front PTO

    Internal engines got a flywheel connected to the crankshaft on one side, and on the other there is a wheel that drive all the engine accessories with a belt. If the main power output would be taken from the "belt" wheel and not the flywheel, would I receive the same power output? And if no, is...

    Internal combustion engine backpressure

    Thanks all for taking part in this disscution. The answer has been found. Here what I've found: Cycle with backpressure may look like this : There are two loops in there, the top one is the indicated work that we get from the cycle (W_ind) and the bottom one is called pumping work (W_pump)...

    Internal combustion engine backpressure

    Hello everyone I got diesel engine, and there is a backpressure applied in the exhaust. I know that when the exhaust pressure reaches approximately 6 atm. the engine stalls. The question is, how I'm able to calculate this precisely, especially when the backpressure didn't reach it's maximum...

    Choosing an efficient compressor

    Billy, thanks for advice. Today I've talked with engineering department in a compressor supplier company. Term of "isentropic efficiency" sound to him like a curse. He didn't really know what is it efficiency, may be he used to work with catalogues and efficiency never mentioned there. He said...

    Choosing an efficient compressor

    Interesting idea regarding the small compressor, but anyways, it suppose to work continiously without any time limits. Regarding the price, it doesn't really matter, I'm not going to buy it, it just have to efficient.

    Choosing an efficient compressor

    The diesel have to be linked directly. The flow rate is about 1300 liters per seconds. It's a big flow rate, compressors that I've found on the net, supplying such a volume per minut and not second. one of the most important factors for me is high efficiency. in order to supple this flow the...

    Choosing an efficient compressor

    Hello everyone. I'm working those days on my graduation project, and I need a little assistance. I have to choose a compressor that would be driven by diesel engine. The compressor should supply about 1.7 kg air and compress it to 2 atmospheres. It seems that centrifugal compressor or axial may...
