Reducing pressure in the fuel line allows for a controlled flow of propane, ensuring that the engine can continue to run even when the cylinder valve is turned off. This is because the residual pressure in the fuel line can still supply enough propane to maintain combustion for a short period. By managing the pressure, the engine can operate smoothly without sudden interruptions, providing a buffer until the propane is fully depleted. However, this is typically a temporary solution, and the engine will eventually stop once the fuel in the line is consumed.
The issue here sounds like it's the master cylinder failing. It is not retaining pressure when the engine is running. The reason they feel fine when the engine is not running is because the failing master cylinder is not getting power, and in essence is being bypassed.
It is the same as it is when you check the compression when the engine is not running. It does not change. It will only get worse as engine wears with time and as miles start adding up on the engine.
No, heat does not reduce the pressure in a cylinder of an engine. In fact, heat typically increases pressure by causing gases to expand. The pressure in an engine cylinder is primarily determined by the combustion process and the movement of the piston.
Cylinder pressure refers to the pressure of the fuel-air mixture inside the combustion chamber of an engine. It is a critical parameter that influences engine performance and efficiency, with higher cylinder pressure generally leading to more power output. Monitoring and optimizing cylinder pressure is key to maintaining engine health and performance.
any gasoline engine will run on either natural gas or propane ( LPG )
a strong engine should read between 150 and 180 pounds of pressure in each cylinder.
If the engine is not running the pressure should be 35 to 40 psi. If the engine is running the pressure should be 30 to 45 psi.
1. Engine compression perform engine compression and cylinder difference test. 2. Fuel filter and fuel pump pressure verify the in tank booster pump is running and producing the correct pressure. Replace all fuel filters.
For an engine to work efficiently, the pressure inside the cylinder must be equal to the pressure outside to allow for proper combustion and expansion of gases. This ensures that the engine can generate the necessary power to move and operate effectively. Any difference in pressure between the inside and outside of the cylinder can lead to issues such as poor performance, engine knock, or even damage to the engine.
Key on Engine not running 55 - 61 psi. Engine running pressure should decrease 3-10 psi.
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.
Yes. I have a 1995 4.6 litre crown Victoria that was originally fuel injected. It is now a propane only car and seems to be running fine.
