It sounds like you may have a fuel supply problem in getting the proper amount of fuel to
the fuel injectors which may be caused by a bad fuel pump or potentially faulty fuel injectors.
The diesel versions of the Drive - E engines also pioneer a brand - new Denso fuel injection system, which uses intelligent
fuel injectors which measure the actual fuel pressure.
It also cleans
your fuel injector which helps you get better fuel efficiency.
Not exact matches
At opposite ends of the sphere, capacitors power larger
injectors which heat a plasma
fuel mix of deuterium and tritium to 1 million degrees Celsius.
Note that this multimeter lacks a frequency testing option,
which can come in handy when you're dealing with some types of sensors and signals, such as speed sensors and
fuel injector control signals.
The device produces an electric field near the
fuel injector and the field thins out the
fuel which means that the droplets of
fuel that get injected into the engine are smaller,
which appears to give more efficient and cleaner combustion.
A
fuel injector like those used in a car atomized the biofuels into tiny droplets that landed on a hot rhodium - cerium catalyst,
which converted the
fuel to syngas.
Over time, the vibrations could lead to cracks forming in the
injector line,
which could lead to a
fuel leak.
This leads me to believe that there is another issue present, something like unmetered air or partially - clogged
injectors which the
fuel management can not accommodate for due to the absence of lambda feedback.
The issue went away after several spirited full - throttle runs,
which tells me that a partially clogged
fuel injector was to blame.
If the
injectors are dropping too much
fuel, it could be fowling the pre-cat O2's,
which goes back to my thinking of there might be (an)
injector (s) stuck open.
Recent activities
which could have triggered the problem include checking the EGR value (clean), checking engine coolant sensor for cracks (none) and having the
fuel injectors pro-cleaned.
Many modern systems have a single
fuel pump
which supplies
fuel constantly at high pressure with a common rail (single
fuel line common) to each
injector.
But this will not be enough, you will have to increase the compression ratio to 11,
which means that you need to buy high compression pistons, lightweight connecting rods, a lightweight flywheel and H22A
fuel injectors.
Code P12a2 is related to the
fuel rail pressure sensor
which reads the
fuel pressure in the
fuel rail to ensure that the proper amount of
fuel is making it to the
fuel injectors.
This relates to a lean
fuel condition
which can be caused by many different things such as: Intake air leaks Faulty front heated oxygen sensor Ignition misfiring Faulty
fuel injectors Exhaust gas leaks Incorrect
fuel pressure Lack of
fuel...
Gas enters the
fuel injectors in a liquid form, and is converted into a mist,
which is then sprayed into the cylinder so that it can burn quickly and efficiently.
In January 1994, due to tightening emissions restrictions, Nissan switched to a lowport design, in
which the
injectors and
fuel rail switched places with the intake plenum.
In February 1994, the 1994 model year was given a new larger chrome - plated grille and door handles, a lowport engine (replacing the original highport SR20DE, in
which the intake plenum is below the
fuel injectors and
fuel rail), a change in the vehicle's self - diagnostic system to OBD - II, and larger 195 / 65R14 tires.
Gas mileage with the five - speed stick - shift was 26 city, 32 highway according to the EPA, limited by weight (2,644 lb for the four - door America model), aerodynamics, and the single
fuel injector; but it was a leap ahead for the Sundance,
which had been rated at 23 city, 30 highway in 1991.
The new engine also received special piston cavities,
which allow the initial combustion flames to propagate without interference, and new multi-hole
injectors,
which enhance
fuel spray characteristics.
The cylinder head incorporates mounting locations for the
fuel injectors —
which are typically mounted in the intake ports or intake manifold on port injection engines.
Piezoelectric
injectors are capable of operating up to five times per cycle,
which helps reduce engine noise,
fuel consumption and particulate emissions.
These include Toyota's Variable Valve Timing with intelligence (VVT - i) system; special lightweight pistons with resin - coated skirts to help reduce friction and noise; a two - stage, variable - length intake manifold,
which improves mid-range to high - speed performance; newly designed 12 - orifice
fuel injectors; Toyota's Direct Ignition System (DIS),
which eliminates the distributor and its associated wiring; and a lightweight electronic throttle.
The new central position of the
injector improves combustion,
which has direct effects on
fuel economy and emissions quality.
Its secret performance lays in a new
fuel supply system
which has faster
injectors that are able to execute many injections in a rapid succession.
Having said that even our petrol wrecks havoc with todays modern
injectors because it is down to the Euro 2
fuel... its just too high in sulfur content
which why you see a higher failure rate for
fuel injectors for modern cars especially performance cars....
It features what is claimed to be the first 2000 - bar Bosch common - rail system,
which makes use of 12 piezo
injectors to deliver the
fuel to the cylinders.
Essentially, SFI D - 4 integrates two types of
fuel injection: A direct - type high - pressure
fuel injection system,
which provides a cooling effect in the cylinders and enables the high compression ratio (11.8:1) employed to extract maximum energy from the
fuel; and a set of low - pressure port
fuel injectors that help produce a precise burn to optimize power and efficiency under light - and medium - load conditions.
Multiport
fuel injection: A system in
which individual
injectors meter and spray
fuel directly into each cylinder of the engine.
D - 4S integrates two types of
fuel injection: a direct - type high - pressure
fuel injection system,
which provides a cooling effect in the cylinders and enables the high compression ratio (11.8:1) employed to extract maximum energy from the
fuel; and a set of low - pressure port

Features
which enable this across a wide range of driving scenarios include multi-hole direct
fuel injectors, a continuously variable capacity oil pump, a variable cooling system and VVT - iE intelligent variable valve - timing on the intake side.
This engine keeps its two turbochargers within the «V» for a more compact layout, and also makes use of a a centrally mounted
fuel injector as well as a combustion method that achieves shorter compression phases and longer expansion phases,
which promotes powertrain efficiency.
Mansory got you covered, as they just released their project Huracan,
which got a hefty boost in performance, from 600HP, to 838HP, thanks to a new turbo - kit,
fuel injectors,
fuel pressure control.
Then you ask someone to analyze the data
which will tell them that the temps gone up and wiggled about and that the
injectors have been open longer (more load = more
fuel) so the physics tells them you have used more energy.
Millennium Industries — Removed robot / GTAW (TIG) weld process issues on Ford / Jaguar
