A system and method are provided that enables windshield wiper blades to be replaced without the complexity of removing and reattaching adapters to the wiper arms with every wiper blade replacement cycle. The wiper blade adapter is reusable and stays connected to the windshield wiper arm while providing a simple connecting system that enables the attachment of the wiper blade to the base of the adapters. The adapters are made of engineered plastic that does not wear as quickly as the rubber squeegee and does not need to be replaced as often as the wiper blade. The reusable wiper blade adapter employs a simple mating connector on the wiper blade that provides for an intuitive motion to attach and detach from the base of the adapter thus providing for a simpler blade replacement process.

Disclosed herein is a wiper blade assembly including: a contact member; an elastic member for supporting the contact member; a cover member for covering the elastic member; and a coupling cover to be fastened to the elastic member. The cover member includes: a spoiler; an extended plate extended from one end of the spoiler; a first coupling protrusion located in a first predetermined position of the extended plate; and a first coupling hole located in a second predetermined position of the extended plate adjacent to the first coupling protrusion. The coupling cover includes: a second coupling hole located in an inner space thereunder and receiving the first coupling protrusion of the cover member; and a second coupling protrusion located adjacent to the second coupling hole and inserted into the first coupling hole of the cover member. The cover member can be reliably fixed to the wiper blade assembly.

A method is provided for evaluating the delivery and effectiveness of engine performance chemicals and products for reducing intake valve deposits for gasoline direct injection and port fuel injection engines. The engine evaluation tool provides the ability to repeatedly quantify the relative improvements between engine performance and maintenance products through a series of tests in a controlled environment with parameters that simulate intake valve and combustion chamber conditions of an engine. Non-limiting examples of test engine parameters illustratively include air fuel ratio, intake air flow, temperature of sample, oscillation frequency, presentation angle of replaceable sample, and product delivery method that includes throttle body upstream, port vacuum in plenum, and by fuel injector.
