Exhaust Leak Part
The problems associated with exhaust leaks vary by the amount of the leak, its speck and what type of fuel injection step your van has. Although most commonality envisage that exhaust leaks are dwarf extra than a source of irritating babel, the actuality is that they can perturb performance, fuel economy, emissions and exhibit a danger to the motorcar's occupants.
If your car was produced after 1995 and has an exhaust leak upstream from the catalytic converter, then the exhaust leak will almost certainly cause a reduction in performance. This can occur because the engine's oxygen sensors are not receiving correct information about the engine's air-fuel ratio, which will cause the engine to inject more or less fuel to compensate. This decreases engine performance, particularly in the low-RPM band.
Carbon Monoxide Poisoning
The unmarried most fatal attribute of an exhaust leak is carbon monoxide poisoning. This colourless and odourless Gauze is a byproduct of combustion and, when inhaled, replaces oxygen-carrying haemoglobin in the blood. The prompt item of carbon monoxide poisoning are nausea, Migraine and vomiting, followed by lethargy, unconsciousness and after all death. The EPA has concluded that one out of five vehicles involved in an accident may have elevated levels of carbon monoxide in the cabin, which ultimately caused the driver to become inattentive. Carbon monoxide poisoning can be recognized by a flushed complexion, and blood that is a bright red (almost orange) in color.
Performance
Noise
The flat of blast associated with an exhaust leak varies with its objective. In regular, the blare emitted by a leaking exhaust Testament dispose louder and sharper with proximity to the engine. A leaking muffler Testament probably one generate a low grumble, a leaking mid-pipe in the catalytic converter Testament fabricate a blustering Bumble-bee at highway speeds, and an exhaust manifold leak Testament eject a pronounced rap that rises with RPM.Fuel Economy
The performance decrease caused by an overly-rich fuel condition will require the driver to use a heavier foot while driving, which will inevitably lead to a decrease in fuel economy.
Catalytic Converter Meltdown
Catalytic converters use a matrix of metal to convert un-burned fuel into less harmful compounds but can only cope with so much. Too much fuel in the exhaust stream will cause the converter's internal temperatures to rise over 500 degrees, melting and cracking its internal matrix. This condition is called "converter melt-down" and can be extremely dangerous. An overheated converter can easily flash-ignite any surrounding combustibles, such as oil, transmission fluid and grease.
