    en.wikipedia.org/wiki/OBD-II_PIDs

    OBD-II PIDs ARSALI (On-board diagn ameter IDs) are codes ut 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.

  3. Onboard refueling vapor recovery - Wikipedia

    en.wikipedia.org/wiki/Onboard_refueling_vapor...

    The vapors which are displaced from the fuel tank by the incoming fuel are routed via the vapor vent line to the canister and are absorbed by activated carbon. These canisters are made of either steel or plastic. The size of this canister is tailored to accommodate expected evaporative emissions.

  4. Secondary air injection - Wikipedia

    en.wikipedia.org/wiki/Secondary_air_injection

    The pump's air intake is filtered by a rotating screen or the vehicle air filter to exclude dirt particles large enough to damage the system. Air is delivered under light pressure to the injection point(s). A check valve prevents exhaust forcing its way back through the air injection system, which would damage the pump and other components.

    EDC injection inline pump. The mechanical fly-weight governors of inline and distributor diesel fuel injection pumps used to control fuel delivery in diesel engines under a variety of engine loads and conditions could no longer deal with the ever-increasing demands for efficiency, emission control, power and fuel consumption.

    It was founded in 1939 as Diesel Kiki Co., Ltd., under a Bosch license, for domestic production of fuel-injection pumps for diesel engines. [1] Originally established with an investment from Isuzu (a major Japanese manufacturer of engines for heavy-duty vehicles), this company was renamed ZEXEL Corp. in 1990. Diesel-Kiki entered into a joint ...

  7. MAP sensor - Wikipedia

    en.wikipedia.org/wiki/MAP_sensor

    Thus, a MAP sensor will always read 100 kPa more than a boost sensor measuring the same conditions. A MAP sensor will never display a negative reading because it is measuring absolute pressure, where zero is the total absence of pressure. Vacuum is measured as a negative pressure relative to normal atmospheric pressure. Vacuum-Boost sensors can ...

    en.wikipedia.org/wiki/Injection_pump

    Injection pump for a 12-cylinder diesel engine An injection pump is the device that pumps fuel into the cylinders of a diesel engine . Traditionally, the injection pump was driven indirectly from the crankshaft by gears, chains or a toothed belt (often the timing belt ) that also drives the camshaft .

  9. Nissan TD engine - Wikipedia

    en.wikipedia.org/wiki/Nissan_TD_engine

    The Nissan TD series is a series of diesel engines manufactured by Nissan. All TD-series engines are inline engines ; most versions are four-cylinders aside from the six-cylinder TD42. They have cast iron blocks and crossflow heads ; the combustion chamber design is a swirl-chamber design with indirect injection and a gear driven cam. [ 1 ]
