ok... i'm certain there is going to be a flaw somewhere in this idea, and i want someone to tell me what it is so i can stop thinking about how it might work. What i was contemplating was taking a 4agze, and converting it to what you might call a 4agmze
what's the m stand for? miller cycle.
i'm sure plenty of you will know what miller cycle engines are, but for those who don't i'll try and fill you in with what little i know about them. (and if i get anything wrong, feel free to correct me)
it's basically a regular 4 stroke engine (otto cycle) with a supercharger, and with the valve timing set up to leave the valves open for part of the compression stroke, so rather than compressing against the cylinder walls, it's compressing against the supercharger. I don't fully understand how it works beyond that (i never claimed to be an automotive engineer of any description) so i'm very open to being shut down on this idea.
mazda have used a v6 miller cycle engine on one of the eunos' and word has it it's a very effective setup. miller cycle engines are supposed to (according to mazda) provide about an ~ 15% increase in efficiency over a similar otto cycle engine, and a reasonable increase in torque too... now i'm not certain of the truth of this, (mazda might just be blowing their own horns so to speak) but i'd be very interested to see how this could work with a 4agze... at the very least you'd need an aftermarket ecu and at least one new cam (and someone mad enough to grind an inlet cam to suit an application like this). You'd also probably need an extended amount of time fiddling to get it running at all, much less in any sort of efficient configuration...
so... what's the word? Any ideas on why this wouldn't work?
EDIT: this idea is brought to you by the brain that tried to work out a way of setting up a 'ground effect' style undercarriage for a friend's track car, the 'you're fucked' dashboard indicator (to let you know when you're upside down) and other such fabulous brain-farts. your abuse is welcome.
