Since there are 4 cylinders, there would be 2000 sparks in that one minute across the whole engine.Īnd no, the piston does not produce the same torque on every stroke. So, if the crank is turning 1000 times per minute, that would be 500 power strokes (firing of the spark plug) on each cylinder in that one minute. That means in a four stroke engine the shaft rotates twice (two revolutions) for every four stroke cycle, which means one power stoke for every two revolutions of the crank.
12 minutes engine full#
From the diagram you can see that a full up and down path of the piston makes for one revolution of the crankshaft. To lay this out, lets look at how many times the shaft rotates with each stroke. In the same way that the speedometer was usually a gear in the transmission that did the same thing just for wheel speed.Īs for the electrical methods, yes, it's just a sensor talking to the ECU which sends the right PWM (Pulse Width Modulation) signal to a gauge in the dash.Īlso assuming a 1000 cc big 4 stroke engine with 4 cylinders running at 1k RPM how many times are each cylinder firing per second or how can that be calculated, also does the piston "revolve" the crank shaft with each stroke even at the exhaust stroke with the same torque or is it different at the firing stroke, if so how is the RPM not constantly going up and down with each different stroke
I'm not 100% sure where the pickoff was for this, but if I had to bet it was just a gear off the crankshaft that gets reduced to a needle movement on the dash. Many older cars did have tachometers though, just mechanically driven. Older cars didn't have a tachometer just because they were not popular, and to limit the cost. I assume the crank shaft, how is it calculated, is it by the crank shaft sensor? Why do some old cars that runs with a carburetor don't have the RPM meter is it for the lack of the ECU and the sensor?Īs for how it's measured, there are both mechanical and electrical ways to measure it. Of course I do realize it stands for revolutions per minute, but revolutions of what?Īs you stated later, it's revolutions of the crank shaft. These engines are four stroke engines, which means the piston goes up and down a total of 4 times, twice up, and twice down for each cycle. Once he leaves, go back to the bedroom and cuddle with the wife’s corpse.Ok, let's start from the same picture so we're on the same page:
Use the cellphone to call 911, lie that the wife committed suicide, and then give the cop the watch. The cop will murder the wife and tell players to call the police.
12 minutes engine free#
Let him stand up and free himself, then calmly go back to the couch and wait. Once the cop starts to wake up, tell him you are innocent and agree to work with him.
12 minutes engine zip#
Wait for him to shock himself, now loot only a single zip tie from his inventory and bind his hands. Now go to the bedroom and flip the light switch only once, enter the closest and get the cellphone, and then wait inside for the cop to break in (it will go faster if the front door is unlocked and open). Similar to the above prerequisites, drug the wife’s water with sleeping pills and grab the watch from the bathroom vent. Once he shows up, openly confess to being a murderer and let her give over the watch to him.
Give the watch to the wife and agree with her to wait for the cop to arrive. Pick up the kitchen knife, enter the bathroom, close the door, open the vent with the knife, and take the watch. During this timeline, once learning about the nanny immediately tell the wife that you now remember killing her father.
