Based on the proposed mechanism, an engine test was developed that reproduces the deposits and injector sticking observed in the field and OEM test stands. This test was used to identify alternate ...

The inlet pressure is 0.25 to 0.50 pounds per square inch gauge (PSIG) while the outlet pressure is 3,600 PSIG (compensated to 70 degrees Fahrenheit).

But unlike fuel-injected gas engines that inject fuel at 10-60 psi, diesel fuel-injection systems run in the 10,000-30,000-psi range.

High-pressure common rail fuel (HPCR) systems are standard on nearly every diesel engine today, from heavy equipment to over-the-road trucks, light-duty trucks, large generators and more.
