Re: [Biofuel] Crower six-stroke engine
is there any way to contact this person? does he have a website? if he can tweak mileage out of a 350 then lets try it with a 2.5L four cylinder, i need to call this guy. - Original Message - From: robert luis rabello [EMAIL PROTECTED] To: Biofuel@sustainablelists.org Sent: Friday, March 24, 2006 11:22 PM Subject: Re: [Biofuel] Crower six-stroke engine Michael Redler wrote: News: Hot rod engineer makes six-stroke engine 17 Mar 06 15:14 Bruce Crower is one of those guys who just isn't content within the box.

Re: [Biofuel] Crower six-stroke engine
This sounds like the combustion cycle used in the Toyota Prius engine. I remember it being called something else regards Doug On Saturday 25 March 2006 4:22, robert luis rabello wrote: Michael Redler wrote: News: Hot rod engineer makes six-stroke engine 17 Mar 06 15:14 Bruce Crower is one of those guys who just isn't content within the box.

[Biofuel] Crower six-stroke engine
News: Hot rod engineer makes six-stroke engine 17 Mar 06 15:14Hot rod builder and former drag racer Bruce Crower has developed an engine that captures the energy usually lost in waste heat. The veteran engineer has been studying this problem for around 30 years, and has now come up with a solution. Crower's six-stroke engine works on the principle of water injection: after the exhaust stroke, as in a conventional four-stroke combustion cycle, water is injected into the cylinders. Both intake and exhaust valves are closed, the water quickly turns to steam and an additional - fifth - stroke adds to the cycle. The steam is then vented from the exhaust valve as a sixth stroke. Efficiency of the engine is said to have been improved by up to 40% and the engine is said to be only warm to the touch after running for an hour. As the water has a cooling effect, increased combustion ratios are possible, leading to improved efficiency and reduced carbon deposits in the combustion chamber. However, fuel vapourisation is a potential drawback and emissions may be increased. The power output in the conventional four strokes of the combustion cycle is also reduced by around a third, and the added weight of the containers for the water - it would need another tank alongside the petrol tank - also affects performance and consumption. Water could also have a detrimental effect on engine life and on catalytic converters. It's unlikely that such an engine would reach production in the near future - water injection has been tried before and the concept discarded - but Crower is to continue with his experimentation. http://www.channel4.com/4car/news/news-story.jsp?news_id=14227___ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
