Police said on Saturday that they believe "a faulty flue and exhaust pipe on a gas heating system" led to a carbon monoxide leak, according to CBS News. A 76-year-old man — later identified as ...
The agency had found that Volkswagen had intentionally programmed turbocharged direct injection (TDI) diesel engines to activate their emissions controls only during laboratory emissions testing, which caused the vehicles' NO x output to meet US standards during regulatory testing.
Carbon monoxide poisoning in pregnant women may cause severe adverse fetal effects. Poisoning causes fetal tissue hypoxia by decreasing the release of maternal oxygen to the fetus. Carbon monoxide also crosses the placenta and combines with fetal hemoglobin, causing more direct fetal tissue hypoxia.
Prior to Volkswagen Group's first TDI engine, the first turbocharged diesel engine used in a passenger car was an indirect injection five-cylinder engine fitted to the 1978 Mercedes-Benz 300SD (W116) 300 SD sedan. [13] The first turbodiesel engine with direct injection was the 1986 Fiat Croma 2.0 TD i.d. liftback sedan. [14]
Carbon build-up in the intake manifold will occur when blow-by gases are allowed to permanently contaminate the intake air because of a failing PCV system. [12] Carbon build-up or oil sludge from blow-by gases on intake valves are usually not a problem in port injected engines. This is due to the fact that the fuel hits the intake valves on the ...
Since fuel is directly injected inside the combustion chamber, it never gets a chance to wash any contaminants behind the valves. This results in excessive carbon build up over time, hindering performance. Some engines (like Toyota's Dynamic Force engines) combine direct injection with traditional multi port fuel injection to ameliorate this ...
