In automotive engineering, an exhaust manifold collects the exhaust gases from multiple cylinders into one pipe. The word manifold comes from the Old English word manigfeald (from the Anglo-Saxon manig [many] and feald [fold]) [ 1 ] and refers to the folding together of multiple inputs and outputs (in contrast, an inlet or intake manifold ...
This is a list of auto parts, which are manufactured components of automobiles.This list reflects both fossil-fueled cars (using internal combustion engines) and electric vehicles; the list is not exhaustive.
The way they do this is during a deceleration of the vehicle when there is low absolute pressure in the intake manifold (i.e., a high vacuum present in the intake manifold relative to the outside air) the powertrain control module (PCM) will open the EGR valve and then monitor the MAP sensor's values. If the EGR is functioning properly, the ...
The inlet manifold of a reverse-flow cylinder head may be connected to the exhaust by a heat riser to transfer further heat, improving low rpm response and emissions as a result. Costs can be reduced in production engines by casting the inlet and exhaust manifolds as one unit. This also transfers further heat to the inlet eliminating the need ...
An exhaust gas temperature gauge (EGT gauge or EGT sensor) is a meter used to monitor the exhaust gas temperature of an internal combustion engine in conjunction with a thermocouple-type pyrometer. EGT gauges are found in certain cars and aeroplanes. By monitoring EGT, the driver or pilot can get an idea of the vehicle's air-fuel ratio (AFR).
The dump valve for the loop and also functions as a drain for water. The counterlung is in the exhalation side of the loop. Water from condensate and leakage is trapped in the bellows before it can reach the scrubber, and can be discharged through the exhaust valve for the loop, which is mounted on the lower plate of the bellows.

OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.
A 4-2-1 exhaust system is a type of exhaust manifold for an engine with four cylinders per bank, such as an inline-four engine or a V8 engine. The layout of a 4-2-1 system is as follows: four pipes (primary) come off the cylinder head , and merge into two pipes (secondary), which in turn finally link up to form one collector pipe.
