How does your car engine work?

    Nice graphic and chart.

    Specifically, an internal-combustion engine is a heat engine in that it converts energy from the heat of burning gasoline into mechanical work, or torque. That torque is applied to the wheels to make the car move. And unless you are driving an ancient two-stroke Saab (which sounds like an old chain saw and belches oily smoke out its exhaust), your engine works on the same basic principles whether you're wheeling a Ford or a
    Ferrari.

    Fascinating article, the technical Induction, Compression, Ignition (power), Exhaust is often colloquially expressed as suck, squeeze, bang, blow.

    What happens unbeknown to many is, the article refers to little explosions which are the power stroke. If you are cruising along the motorway/freeway the engine will be doing around 2500 rpm, in one hour of driving it will rev about 150,000 times. As the article points out every second stroke is ignition (the explosion) so that will be 75,000 per hour but per cylinder. Most cars have four cylinders so 300,000 little explosions per hour.

    Three hour drive and you are looking at around a million little explosions occurring under the bonnet/hood.

    All this while elegantly driving in reasonable silence. Amazing really.

Geffers Still laughing at this.....is often colloquially expressed as suck, squeeze, bang, blow. Your math is interesting on the number of explosions per hour while driving. It is amazing how advanced engineering has made the inside of the car pretty quiet. Makes for a nicer long drive if you have the opportunity to drive out in the country away from major highways to enjoy the experience.

In UK we have some very quaint country roads and lovely villages. Some roads so narrow there are passing points or someone has to back up. I enjoy driving in California, although your STOP signs are so frustrating. Most junctions in UK are Give Way (Yield) or traffic lights. There is one rode I drive often when in CA. Pacific Ocean and beach to my right, footway leading to road to my left, perfect vision in both directions, in UK we wouldn't even slow for this (provided no people about) but there, mandatory stop sign Geffers

It can be a real predicament if there are two cars on the road coming towards each other. Nice that the UK has passing points for those issues. I live in the US and our traffic system annoys me too, lol. I like your give way/yield solution. OMG, there's a mandatory stop sign in Ca for that roadway set up?
