urfsin Posted April 27, 2011 Share Posted April 27, 2011 Why not? The Internal Combustion Engine is lagging bad in some technological ways. I think camshafts are the next thing to go.....with computer technology you could activate the valves based on an electronic signal rather than some chunk of metal spinning around. It would eliminate a fair amount of drag on the engine and increase HP / efficiency. Slide It Sideways Link to comment Share on other sites More sharing options...

I think camshafts are the next thing to go.....with computer technology you could activate the valves based on an electronic signal rather than some chunk of metal spinning around. It would eliminate a fair amount of drag on the engine and increase HP / efficiency. F1 engines have been using pneumatic valve control systems for some 20 years now. Read more here. Claims of much improved efficiency are a bit preposterous. Modern engines are already igniting and burning the entire fuel mixture. If anything it would allow more control over timing and give a little wiggle room with leaner mixtures. That being said, if spark plugs were the drawback in terms of modern engine efficiency, one would think every car maker would have copied Alfa Romeo / FIAT Twin Spark engines. As for me, I use Pulstar or Nology spark plugs and the Tornado Air Supercharger to improve my efficiency and burn more than 100% of the mixture.

I think camshafts are the next thing to go.....with computer technology you could activate the valves based on an electronic signal rather than some chunk of metal spinning around. It would eliminate a fair amount of drag on the engine and increase HP / efficiency. Camshafts are there because they are cheap and reliable. Of course - if the engine makers could they would build 2-stroke engines because they are even cheaper to build and you can get a lot of top power for the cost but they suck when it comes to drivability and fuel economy so... But don't forget that other valve technologies will also require power to operate, so maybe the camshafts aren't such bad idea after all. The variable timing camshafts are one solution and using a CVT gearbox another. And for those that thinks that CVT gearboxes sucks - it's because they are tuned for fuel economy, not power. Just look at the FW15C which got banned from ever racing in F1. However you can also look at what Ducati does - their desmodromic (desdemonic ) valve technology. They are doing really well, but they require a bit more maintenance than ordinary valve tech. Link to comment Share on other sites More sharing options...
BAC5.2 Posted April 28, 2011 Share Posted April 28, 2011 No one thinks CVT's suck. Just that they aren't as fun to drive.

MasAyinde Posted May 20, 2011 Share Posted May 20, 2011 I think we've all seen the inside of a combustion chamber. Wouldn't it take just a few seconds of running rich to cover up and block the laser light? Link to comment Share on other sites More sharing options...
