If a 1989 Jaguar XJ6 will not start but you have a have spark and fuel and pressure is delivered to the injector pipe however no fuel enters any cylinder what could be wrong?

Answer

Fuel injectors are not opening. They open by electrical pulse from the ecu. You could have a short, a broken wire, perhaps a bad fuse or the ecu could be defective.


You also might have a bad crack sensor on the front of the engine. ECU doesn't know the position of the cylinders therefore no activity to fuel injectors etc...

Pressure washers use an attachment called a chemical injector to siphon soap into the water stream. The chemical injector works based on the the physics principle known as the Venturi Effect. The Venturi Effect occurs when there is a restriction in a medium through which water or air is flowing. This restriction causes an increase of speed in the flow, but a drop in pressure. A chemical injector uses this drop in pressure to siphon chemicals or soap into the water stream. With a chemical injector, this drop in pressure is achieved by using a nozzle with a large opening. There are two main types of chemical injectors:Downstream injector- This type of chemical injector is placed on the outlet side of the pump. A special nozzle is used (as mentioned above) to decrease the pressure to that the chemical can be siphoned.Upstream injector- This type of chemical injector is placed on the inlet side of the pump to inject the chemical into the water before it enters the pump. This type of injector is also known as a "high pressure" injector because the chemical is pumped through the pressure washer, and is thus released at the high pressures with the water. This is the only type of chemical injector that you can use different nozzles with. Since the chemical is injected using the low pressure inlet hose (garden hose), you do not need a special nozzle to decrease the pressure on the outlet side. This type of chemical injector is usually not recommended, however, due to the fact that the chemical is circulated through the pump. This can cause seals, such as the pump's o-rings, to wear out faster.

the 1998 ford escort does not have a fuel pressure regulator. It does however, have a fuel pressure sensor located on the fuel injector rail. It has a connector attached to it and can be removed by taking out the attaching screws and twisting and tugging on it.

Fluid power comes in two forms: hydraulic and pneumatic. The pump in an hydraulic system is a flow source, delivering a set amount of fluid every revolution. Pressure is an effect due to restriction on flow in the circuit. If the oil delivered by the pump is used to operate a cylinder, the pressure that develops is due to load on the piston. If the pressure required to move the load on the cylinder is greater than the setting of the relief valve, the piston will not move and all the oil will pass through the relief valve. Also, when the piston has moved to the end of the stroke, it cannot move any further, however the oil delivered by the pump goes over the relief valve. If there wasn't a relief valve, the pressure will build up until the oil from the pump can flow somewhere: by bursting a hose or breaking the pump or cylinder.

There is no fuel injection pump the fuel pressure going to the injectors should be about 60 PSI then the injector does the rest. There is a high pressure oil pump which provides high pressure oil to the injectors however a switch monitors that and if it is low the engine will not crank or run.

Hydraulic systems work because liquids are, for all practical purposes, incompressible. When you apply pressure to the master cylinder in a hydraulic system, that pressure is transmitted equally throughout the system.Gases, however, are extremely compressible. When you put pressure on the master cylinder in a hydraulic system in which there is air in the lines, all that happens is that you compress the air in the lines; the pressure is NOT transmitted to the working cylinders.

Modern fuels have a fuel injector injector cleaner built into them. However I do recommend you use a good fuel injector cleaner such as Seafoam or Chevron Techron once a year.

Your question makes little sense. If a cylinder holds 6 cubic meters of nitrogen at one atmosphere pressure the volume of the cylinder is 6 cubic meters. However as 150 newtons per squsre meter = 150 Pascals = 0.001480384754 atmospheres, if you took 6 cubic meters of nitrogen at this pressure and then increased the pressure to 1 atmosphere the volue would shrink (because the volume of a gas is inversely proportional to the pressure) from 6 cubic meters to 0.008882308524 cubic meters.

Buy a rear brake cylinder re-winder $60. However, you can also struggle with a C-clamp and needle nose pliers, pressure - turn, pressure-turn, pressure - turn. The rear pistons rotate as brake pressure is applied which allow them to lock with the parking brake.

Depends on the car. If it is naturally aspirated (no turbo or supercharger), then it's easy. Cylinder pressure = 14.5 (1 bar) * Compression Ratio. If however, it's forced induction: Cylinder pressure = ( 14.5 (1 bar) + Boost psi ) * Compression Ratio. For instance, in a naturally aspirated car with a 10.0:1 Compression Ratio : 145 psi = 14.5 * 10 Or in a turbo car with the unreasonably high 10.0 compression ratio with 10 psi boost : 245 psi= ( 14.5 + 10 ) * 10

Fuel injectors are very precise, very fragile pieces of equipment.If one is faulty, you can attempt to clean it with fuel injector cleaner. However, replacement may be your best bet.

If the gas is compressed into the cylinder, yes. However if the gas is already pre-compressed (to the point of liquefaction) and simply decanted into the cylinder, there will be little to no heating of the receptacle cylinder.

The fuel pressure regulator is located under the upper manifold plenum behind the injector (or spider assembly), because it is inside the manifold no vacuum line is necessary. You should note,however that none of the "popit type" injectors have fuel around them as this is the most common failure of this fuel system.

If the flow is subsonic the pressure will increase, if however it is supersonic the pressure will decrease.

Generally, NM (Newton Meter) is a force times the length of the arm. Bar is Pressure (force per unit of area). The conversion is not possible to calculate because of the difference in extensions (NM or N/mยฒ). However, in engine design the load of the engine can be given in bar (cylinder pressure) but converted into torque (N-m) by the following conversion: Cylinder Pressure (bar) = Torque (N-m) * nrev * 2 * pi / Cylinder displacement (cubic meters) / 100,000 where: nrev = number of revolutions per cycle (2 for a 4-stroke engine, 1 for a 2-stroke)

The pressure of gas has nothing to with ATP. However, the pressure of gas at STP, or Standard Temperature Pressure is 0 degrees Celsius and pressure is 1 ATM.
