6.8 Post-Lab Analysis Now we're going to design another "equalizer". Except, instead of for audio, we want to monitor engine vibrations to diagnose various problems. Suppose we have a four-cylinder engine with a single camshaft. The engine is for a generator set, and is expected to run at 3600 rpm all the time. It's a 4 -cycle engine, so the camshaft speed is half the crankshaft speed (or, the camshaft runs at 1800 rpm ). Each cylinder produces one exhaust pulse per camshaft revolution. We want to measure the following things... - Vibrations caused by crankshaft imbalance. - Vibrations caused by camshaft imbalance. - Vibrations caused by the exhaust wave. The exhaust wave pulses whenever an exhaust valve opens. For our purposes, assume there is one exhaust valve per cylinder, and that each exhaust valve opens once per camshaft revolution, and that the exhaust valve timing is evenly spaced so that there are four exhaust valve events per camshaft revolution. 1. Figure out the frequency, in Hz , of each of the vibrations you're trying to measure. 2. Set the cutoff frequencies for each of your handpass filters. 3. For one of the three vibrations, determine R and C for your bandpass filter, and draw the bandpass filter using a generic op-amp. You don't need to show the power supplies.
