Abstract: In an engine, an air cleaner and a muffler are located laterally opposite to each other with an engine body therebetween, the air cleaner and the muffler are located forward of the engine body in the longitudinal direction, a fuel tank is longer laterally than longitudinally when viewed from above and is located rearward of the engine body in the longitudinal direction, and an oil filler port which is sealed by a cap is provided to the fuel tank at a position laterally deviated leftward. A level gauge, which can be visually recognized when the cap is removed and the oil filler port is viewed from above and from the front side longitudinally, is provided inside the fuel tank.

Abstract: An oil level gauge guide apparatus including a body of an internal combustion engine, a case member attached to the body so as to cover a moving part disposed on a side of the body, a passage forming member forming a gauge passage through which an oil level gauge passes between the body and the case member, and a guide portion provided at a lower part of the passage forming member to guide the oil level gauge to the gauge passage. The body and the case member include a first and second facing surfaces facing each other so as to form a space to accommodate the moving part and the guide portion is extended along the gauge passage and protruded from one of the first facing surface and the second facing surface to the other of the first facing surface and the second facing surface.

Abstract: A dipstick assembly includes a handle and a dipstick contacting the handle and being supported thereby, where the handle includes a waist portion including a first material and a head portion including a second material, the first material including a thermoplastic elastomer.

Abstract: Instant Reading Oil Dipstick Improvements is a near universal design with most assembly done by the manufacturer. The customers can easily adapt such to match their existing dipstick geometry by pushing the adjustable parts to the correct location, where they will remain. The air valve is within a single, machined brass cone that adapts to the metal tube and seals in the engine vacuum. A new tubular plastic air seal around the wire handle increases reliability. And a cone shaped rubber squeegee will automatically remove oil from the outside of the tubing as the dipstick is withdrawn from the crankcase.

Abstract: The present instant reading oil dipstick automatically extracts a representative column of oil from the crankcase oil reservoir. Such is done inside of a translucent fluoroplastic tube. A machined brass slide valve, with sealing O-rings, fits inside of the metal dipstick tubing leading into the engine crankcase. When the dipstick is withdrawn for checking oil level, the slide valve automatically closes over an air vent in the plastic tubing, thus preventing the oil that is inside the bottom of the tubing from running out. The oil level can be ascertained, easily—even in low light levels—without have to wipe off the oil from the outside of the dipstick, and without having to reinsert the dipstick one or more times.

Abstract: A volume indicator for use with a container is provided. The indicator includes a body having a gradient opening defined therethrough at a predetermined angle. The gradient opening is associated with a predetermined volume or height of material in the container. The predetermined angle compensates for a line of sight angle of a user into the container.

Abstract: An oil level gauge includes a handle section, a shank section, and a measuring section. The measuring section includes an upper limit mark and a lower limit mark in an up and down direction. The measuring section has a curved shape in a direction perpendicular to a longitudinal direction of the measuring section.

Abstract: An oil level gauge including an ullage rod that is segmented and retained as a unit by a tensioned cable and having a fluted surface in the fluid measuring area to assure accurate nonwiping reading of the oil level.

Abstract: A dipstick wiper is provided for use in association with a dipstick of the type having an elongated blade which is proportioned to extend through an open end of an access passage of an access tube into a fluid reservoir for the purposes of determining the level of fluid in the reservoir. The dipstick wiper is in the form of a stopper for stopping the open end of the access passage of the access tube. A seat is formed in the lower end of the stopper for receiving the open end of the access tube in a close-fitting relationship to mount the stopper at the open end of the access tube in a position in which it stops the access passage. First and second through passages open through the stopper. The first through passage is proportioned to accommodate a blade of a dipstick in a close fitting sliding relationship so as to serve to wipe the blade clean when it passes therethrough.
