What causes diesel injector tips to break off?
What causes diesel injector tips to break off?
When there is a lack of fuel in the injector (or air in the system), the needle violently slams shut against its seat, which can quickly lead to the formation of cracks.
How many miles can a 7.3L fuel injector go?
The fuel side of the 7.3L fuel injector contains many more components, which are not normally considered ‘wear’ items. With proper fuel filtration, good, clean diesel fuel, and adequate fuel pressure, the fuel side of the injector can go well in excess of 400,000 miles without issue.
What is the poppet valve on a 7.3L fuel injector?
Each 7.3L fuel injector can be thought of as having an “oil side” and a “fuel side”. The oil sideof the injector has one main component, called the poppet valve. The poppet valve operates JUST like a valve in a cylinder head.
When to torque down diesel injector lines and purge air?
As soon as possible, torque down the remaining injectors. Any delay will result in diesel fuel spraying all over the engine bay. There may be a few minutes of a rough idle, because remaining bubbles might need to work their way through the injectors. At this point, the IDI should be idling.
How does the injector pump work in a diesel engine?
The Injector Pump (IP) creates hundreds of PSI of pressure in the injector lines. The injectors “pop” at a high pressure, which sprays diesel fuel into the cylinder head. If there is air in that injector line, the IP output pressure is padded by the bubbles and the requisite high operating pressure is never achieved.
What causes a fuel injector to stop delivering fuel?
Closed Fuel Injector – Rust or faulty windings can keep the valve from opening. A winding can short out, overheat or break. Rust can cause it to stick. If it can’t open, it can’t deliver fuel. Open Fuel Injector – A faulty spring or rust build up can cause a valve to stick in the open position. This will cause the injector to leak fuel.
