Angle choke valve - Relief valve orifice sizes - Water heater relief valve Angle Choke Valve
1963 VW (old Corvair engine) Old engine before the Honda was installed. That's a Corvair that's been modified a tad. Note the 750 double-pumper, T04 turbo (H3 compressor) and injectors. Injectors were used to handle idle fuel flow so the engine would idle consistently and not puddle fuel in the manifold. Had about 9 inHg manifold vacuum at idle (1500 rpm). Did sound real nasty though. Cam was 248 deg at 0.050 tappet lift and 318 deg at lash (slow ramps to avoid valve train breakage). Had roller rockers, stud girdles, 1.450 OD springs and 3/8 inch pushrods. Also used VW rabbit connecting rods (beefy) and 90.5 mm Cima pistons and cylinders. A dry sump oil system was used to allow the headers to be routed under the oil pan (ground clearance) and provide good oil control during hard cornering. Water/alcohol injection with lead added to the fuel was necessary to avoid detonation. Power was 195 hp net at wheels using 16 psi boost (about 244 hp on a typical chassis dyno). Problem is the heads don't flow air worth beans (only 128 CFM at 0.5 in lift and 28 inWa). No flow, no power. Power drops like a rock as rpm increases past point of peak power (port choke). Valve sizes were 38.5 mm x 35.5 mm. BTW, a stock 110 hp head flows only 80 CFM with the intake valve removed. I designed billet heads for the engine (that's originally why I bought the vertical mill) with NICE ports, but I came to the realization that the bottom-end would scatter if the heads did work. That's when I went to Honda power. Like it or not, the Honda has tremendous potential and is lot lighter than a DSM 4G63. This all fit under the stock hood. Key to accomplishing that was the water cooled heads and cylinders. Trouble was the water cooling didn't work very well which is one reason the water/alcohol injection was necessary. I would have been better off figuring out a way to repackage the air cooled design to fit under the hood. Too late now ... I have moved on. CFIA inspector/vet turning valve to release CO2 gas to suffocate turkeys
Mass depopulation of the Manitoba turkey breeder barn that tested positive for Avian Influenza was carried out on Sunday, November 28, 2010. CETFA inspectors were on-site in an attempt to audit and document the depopulation. Similar to the Avian Influenza outbreak in BC in 2004 where ultimately 17 million birds were killed by the CFIA, no animal welfare organizations were invited to oversee the process. After the 2004 outbreak, farmers testified at a Parliamentary Standing Committee on Agriculture that the CFIA failed miserably in ensuring a speedy, pain-free demise for their birds. One producer shared the experience of his 100,000 ducks. The CFIA chose to use "in-barn" gassing - the same process chosen for this outbreak as well - whereby vents are covered and carbon dioxide gas is pumped into the barns to suffocate the birds. The ducks revived three to four times, taking hours to finally suffocate to death. Another producer told of how the same "in-barn" gassing left 60% of his chickens alive and suffering. Carbon dioxide is aversive and causes profound respiratory distress in birds. It converts to carbonic acid, burning the birds' mucous membranes. I witnessed the killing of chickens with carbon dioxide at a large slaughterhouse in The Netherlands and was disconcerted with what I saw - the chickens gasped, shook their heads, stretched their necks in an attempt to breathe and convulsed severely enough to fracture wings and legs. Inhalation of CO2 by birds has been described by Dr. Mohan Raj, Senior Research Fellow at the University of Bristol as "distressing and inevitably painful." It has been 6 years since the CFIA's botched euthanasia of 17 million birds in BC. Can this really be what years of studies have determined - to use the same inhumane method? - Twyla Related topics: motorcycle air valve quiet silent check valve gate valve pictures check valve price 3 way ball valve flanged ball valves pool skimmer float valve |
