Combustion analysis equipment showing the air/fuel ratio and/or carbon monoxide production assists in correctly tuning an engine. Excessively lean mixtures can cause engine problems, although fuel economy is improved with a lean mixture. To ensure all cylinders obtain sufficient fuel to produce maximum power, the mixture must be rich.
Why would a gasoline engine be set rich? The distribution of a liquid fuel, such as gasoline delivered through a carburetor, is not uniform. Other causes of high CO production include a cold engine, misfiring, incorrect engine timing, defective or worn parts, exhaust system leaks, and defective catalytic converters. A gasoline engine producing 10,000 ppm CO at the ideal air-fuel ratio will produce over 60,000 ppm when the fuel is increased. Two major causes are a rich fuel mixture (more fuel than is needed), or restricted air supply (dirty or plugged air filter). Anything that leads to incomplete combustion increases CO production. Why does the concentration of CO produced vary? Carbon monoxide is produced during incomplete combustion. Recent regulations affect small engines such as those used on lawn mowers, chain saws, weed eaters, electric generators, water pumps, and boats, although the regulations for small engines will continue to allow considerably higher CO concentrations than the tighter regulations for on-road motor vehicles. Engines used indoors were not originally regulated. In 1968 the EPA regulated CO emissions from on-road motor vehicles. Carbon monoxide is a cumulative poison which can rise to harmful levels in the body in minutes.ĭoes the concentration of carbon monoxide produced by engines vary? Yes, CO emitted from the tailpipe of engines burning gasoline, diesel, or LPG (propane) varies from over 100,000 parts per million (ppm) to less than 15 ppm. High concentrations of CO interfere with thought processes complicating the diagnosis. The effects of carbon monoxide at low concentrations mimic common influenza and often are not recognized. Carbon monoxide (CO) is colorless, odorless, tasteless, and non-irritating.
Several of these combustion products are linked to health problems.ĭuring incomplete combustion, carbon monoxide, a deadly toxin, is produced. During complete combustion, the typical combustion products from engines are carbon dioxide, nitrous oxides, particulates, water vapor, and numerous other contaminants. Overall if you want to play it, don’t expect much, and prepare to stare.The use of internal combustion engines operating on gasoline, LPG, diesel fuel, or natural gas inside buildings presents a serious risk of carbon monoxide poisoning. The whole final quarter of the game is utterly pointless and adds nothing to the story except making it harder for the player.
That's fun till it all crumbles and becomes meaningless. The plot starts interesting and leaves you with some tools on the table and lets you figure things out. The game is repetitive, mind-numbing, and boring. Over and over and over again for hours until you do some small thing differently then you get some info then it’s the same dialogue, same janky animation, same scenes repeating. It’s fun for the first hour or so until you sit there moving around the same small apartment, going through the same dialogue, and getting the same results. This by far was an utter disappointment and a waste of time in the end. This by far was an utter disappointment and a waste of I waited a solid year for this title and feel bad for those who had to wait longer.
