It provides information about track in-use performance for catalyst banks, oxygen sensor banks, evaporative leak detection systems, EGR systems and secondary air system. The numerator for each component or system tracks the number of times that all conditions necessary for a specific monitor to detect a malfunction have been encountered.
Along with the screen and UI, some tests were available to run, including an EVAP leak test and O2 monitor tests. There's also a print function via Micro-USB that could come in handy.
Vehicle emissions control is the study of reducing the emissions produced by motor vehicles, especially internal combustion engines.The primary emissions studied include hydrocarbons, volatile organic compounds, carbon monoxide, carbon dioxide, nitrogen oxides, particulate matter, and sulfur oxides.
Gaskets and shaft seals were intended to limit the leakage of oil, but they were usually not expected to entirely prevent it. The blow-by gases would diffuse through the oil and then leak through the seals and gaskets into the atmosphere, causing air pollution and odors. The first refinement in crankcase ventilation was the road draught tube.
OBDII + catalytic converter tamper check + fuel cap leak test for 1996 or later vehicles. Tailpipe/tampering testing for 1995 and older vehicles. Any diesel vehicle with a model year of 1975 and newer and a GVWR of 10,500 lbs or less. Annual testing. OBDII + catalytic converter tamper check + fuel cap leak test for 2002 or later vehicles.
However, uncooled EGR designs do exist; these are often referred to as hot-gas recirculation (HGR). Cooled EGR components are exposed to repeated, rapid changes in temperatures, which can cause coolant leak and catastrophic engine failure. [9] [10] Unlike spark-ignition engines, diesel engines are not limited by the need for a contiguous ...
A car cooler is an automobile evaporative cooler, sometimes referred to as a swamp cooler. [ 32 ] [ 33 ] Most are aftermarket relatively inexpensive accessories consisting of an external window-mounted metal cylinder without moving parts, but internal under the dashboard or center floor units with an electric fan are available.
A leak appearing within an analytic region (a rule added to the camera) is immediately analyzed for its attributes, including thermal temperature, size, and behaviour (e.g. spraying, pooling, spilling). When a leak is determined to be valid based on set parameters, an alarm notification with leak video is generated and sent to a monitoring station.
