A working model of a typical 4-cylinder inline engine. Demonstrates a concept I had for moving pistons I wanted to share with others. Has moving parts to show the basic powertrain operation. No controls, sorry; Not much to do but turn it on/off :)

    you could make it more realistic by having it slightly bigger and making some oxygrn coming in from a carbrator

    Seriously genius. No small amount of effort here and a spectacular application of knowledge.

    wow the real one is much faster than this one. It's such a bad save. Nonono just kidding :) it's WONDERFUL :D

    3rd comment but maybe someone will learn something: Firing order is designed that way to minimise stress on components and maximise power to the crank. In a 4-cylinder engine, having 2 cylinders firing at once would mean there's a downstroke with absolutly no power being applied. With all 4 firing as they do, every time a piston moves down, it does so under the power of another piston.

    There are others besides 1-3-4-2, but none fire two at once TIKO. :)

    @jammy: No, that's not a real firing order. I'm not aware of any straight 4's that fire 2 cylinders at a time. 1, 3, 4, 2 is the most common order.

    you coud make 1 and 3 go off at the same time then 2 and 4 to make it more realistic

    I like machines. I think a lot of other people like machines, too. I'd like to see more excellent machines on FP. Engine makers and engineers I encourage you to take your time! I've seen lots of otherwise awesome-looking machines that are let down because they don't operate like their real-life counterparts. Make awesome stuff and make it awesome!
