Absorption of the medicine is slower than that of intramuscular injection. Induction heating improves energy efficiency for injection and extrusion processes. Biopharmaceuticals have to be given by injection or infusion. Sequential fuel injection and knock control. Fuel was delivered via Multiport Fuel Injection. This engine used the TBI throttle-body fuel injection. She did administer the fatal insulin injection. Engine output was up an additional from sequential multi-port fuel injection. However, there are a number of problems inherent in the use of syringes for injection. Common side effects include pain in the area of injection and allergic reactions. It later gained popularity for making short run injection molding dies. Both engines were equipped with electronic fuel injection. On many OM602 engines fuel injection is indirect. It indicates it has a direct fuel injection. Common side effects include pain at the site of injection and allergic reactions.
