What is better common rail or direct injection?

A common rail is one of the most important components in a diesel and gasoline direct injection system. The main advantages of the common rail direct fuel injection can be summarized in reduction of exhaust and noise emissions, better fuel efficiency and improved overall engine performance.

How do you release pressure on common rail?

You don’t need to disconnect the fuel rail to pull the motor, just unbolt it from the manifold and set it to the side. You can bleed it by slowly releasing pressure via the Schrader valve under the green cap on the fuel line. Wrap a rag around it as you will get fuel spray until the pressure is released.

What pressure do fuel injectors run?

43.5 psi
The Effect of Fuel Pressure on Injector Flow Rate Most injectors are flow rated at 43.5 psi. (Motorcraft rates their injectors at 39.15 psi.)

What are the principles of tuning a common rail engine?

The general principles of tuning a Common Rail engine are similar to a PD – get more fuel and air into the engine at the right time and you’ll be making more power. There are however a few other things that need to be considered.

What are the tuning steps for a drum set?

Summary of Tuning Steps 1) Choose the fundamental notes for every drum using Table 1. 2) Decide on the amount of Resonance1: low, medium, high or maximum and if top or bottom head is higher in lug-frequency. 3) Calculate the top and bottom head lug-frequency for every drum head.

How is the fundamental pitch of a drum tuned?

With a two-headed drum, the fundamental pitch of the drum can be varied by adjusting either top or bottom heads so there are an infinite number of top and bottom lug-pitch combinations for any specific fundamental pitch. The resonance (or sustain) of the drum depends on the lug-frequency relationship between the top and bottom heads.

How much pressure does a common rail engine have?

Through the years injection pressures have been steadily increasing. Early fuel systems were rated to 1350 BAR, and the latest systems in engines developing well over 100bhp per litre use 2500 BAR of fuel rail pressure with 3000 BAR systems on the horizon.
