Following this path, this work studies a new configuration called double-tube characterized by injecting the gaseous oxidizer through a head end injector and an inner tube with injector holes distributed along the motor longitudinal axis.
Contrast was administered at controlled room temperature into the port-a-cath unit via a dual head power injector (Nemoto-Kyorindo, Tokyo, Japan).
A L'Orange fuel injection system comprises individual fuel injection pumps, very short injection lines ducted through the lower part of the cylinder head, and injectors which are cooled by the engine lube oil system.
A total of 60 ml non-ionic contrast material (370 mg iodine/ml, Ultravist; Bayer-Schering, Berlin, Germany) was injected at a flow rate of 8 ml/s using a dual-head power injector (Nemoto Kyorindo, Tokyo, Japan), followed by a 30-ml saline chaser.
Contrast medium was administered by using a dual-head pump injector (Stellant, Medtron, Saarbruecken, Germany).
Contrast material was administered by using a dual-head pump injector (Stellant, Medtron, Saarbruecken, Germany).
A nonionic contrast medium (80-100 mL; iopamidol, 370 mg iodine/mL; Bracco Sine Pharmaceutical Corp. Ltd., Shanghai, China) was administered immediately followed by 40 mL of saline chaser solution was administered through an 18-gauge intravenous antecubital catheter at a flow rate of 6 mL/s with a dual-head power injector (Stellant; Medrad, Indianola, PA, USA).
A 64-detector row Toshiba Aquilion CT scanner (Toshiba Medical Systems, Tochigi-ken, Japan) equipped with a Medrad Stellant dual-head contrast pump injector was installed in 2007, replacing the original single-detector-row machine and allowing thin collimation peripheral run-off studies.
All patients will receive pre-warmed (37 °C, 99 °F) iodinated contrast material (Ultravist; 300 mg I/ml, Bayer Healthcare, Berlin, Germany), administered automatically using a dual-head CT power injector (Stellant, Bayer).
Position the Fuel Rail in place and gently and evenly push it onto the head and air injectors.
