Like a lot of other questions, the answer is, "It depends."
Most fuel injection systems these days are "port fuel injection" in that the fuel injectors are located upstream of the intake valve. Different manufacturers use different pressures, but most are in the range of 2-4 atmospheres (200-400 kPa or 30-60 psi).
The newer Direct Injection engines have two fuel pumps. The one in the fuel tank pumps fuel forward to the engine at a pressure similar to the port fuel injection systems. Mounted on the engine is a high pressure pump that pressurizes the fuel to a very high pressure and that is then transported via metal pipes to the injectors that empty directly into the combustion chambers themselves.
Diesels usually have the higher pressure, engine-mounted fuel fuel pump, but may or may not have a lower pressure electric pump located in the fuel tank or in the fuel line between the tank and the enging.
It may vary on the type of engine usage for exammple it may be around 100 bar for heavy duty applications but for CRDI engines it may be as high as 1000bar.
What else can I help you with?
Fuel injection pump in ic engines?
If you are asking, "Is there a fuel injection pump in an internal combustion engine with fuel injection?". then the answer would be Yes, it is the fuel pump itself. If that is not your question then please rephrase your question and try again.
What force creates injection pressure values in a EUP-managed engine?
The injection pressure values in an Electronic Unit Pump (EUP)-managed engine are created by the high-pressure pump located in the fuel system. This pump pressurizes the fuel to a level required for efficient injection into the combustion chamber, enabling optimal engine performance.
What is the effect of advanced fuel injection timing on brake mean effective pressure?
The fuel injection timing in a gas engine will not affect the mean effective pressure. In a diesel engine is the principal factor managing the bmep. In a gas engine the fuel injection timing have to match the events of valve opening or tuned induction but have nothing to do with mean effective pressure.
What is difference between injection rate and injection pressure?
The injection rate is the number of injections. The injection pressure is the pressure the injection is under.
Operating principle of gasoline direct injection engine?
injection of fuel at high pressure is done directly into the cylinder where combustion occurs.
What does fuel injection do for your car?
Electronic Fuel Injection assures a steady pressurized flow of gasoline into the combustion chambers of the engine. A mechanical pump maintains the pressure instead of vacuum pressure as it was in normally asperated engines.

What is difference between ic engine and automobile engine?
Automobile engines are ic (internal combustion).
What is idling fule pressure for a 1995 s 10 with 4.3 vortec?
With key on engine not running pressure should be 9 to 13 psi Engine at idle pressure should decrease by 3 to 10 psi on a throttle body. On a multi port injection key on engine not running pressure should be 41 to 47 psi. Engine running at idle pressure should decrease 3 to 10 psi. Central multiport fuel injection key on not running should be 58 to 64 psi. Engine running at idle pressure should decrease 3 to 10 psi. Central sequential electronic fuel injection key on not running pressure should be 55 to 61 psi. Engine running at idle pressure should decrease 3 to 10 psi.
What is the difference between ic engine and ec engine?
IC & EC engines are heat engines and they convert heat into work. Example of an IC engine is a petrol engine and example of an EC engine is Steam Engine. The main differences between them are listed below: 1) Combustion: The main difference is where the combustion takes places. In IC engines fuel combustion takes place inside the cylinder, whereas in EC engines it takes place outside the engine cylinder. 2) The temperature and pressure in an IC engines is much higher than those of EC engines. 3) IC engines are made of materials that are better resistant to heat and pressure than in EC engines. 4) In IC engines the piston is directly connected to connecting rod, whereas in an EC engine there is a stuffing box. 5) Efficiency is higher for IC engines. 6) Boilers are required for EC engines to store water, which is to be converted to steam. But IC engines require only a much smaller tank to store fuel. 7) EC engines, unlike IC engines cannot be started or stopped quickly, because it takes time to initiate boiling of water and generate steam. 8) IC engines are lighter than EC engines. 9) IC engines are cheaper compared to EC engines.
What does HDIS mean?
HDI is High pressure Direct Injection engine that is found in diesel cars. Fuel is injected into the combustion changer under high pressure.
