An improved roller for a dynamometer includes a plurality of equally spaced, congruent recesses parallel to the longitudinal axis of the roller and circumferentially positioned around the perimeter of the roller The recesses form a plurality of equally spaced, substantially planar, congruent surfaces parallel to the longitudinal axis of the roller and circumferentially positioned around the perimeter of the roller The surfaces engage the drive wheel of a vehicle and limit slippage and/or creepage between the drive wheel and the roller resulting in increased power transfer between the drive wheel and roller and increased dynamometer accuracy and repeatability.
A motorcycle engine cover bumper device ( ) includes a road engagement memberr ( ) joined to an outer wall ( ) of a motorcycle engine cover ( ) such that the road engagement member ( ) engages a road surface before the motorcycle engine cover ( ) thereby preventing damage to the cover when a motorcycle ( ) travels around a road bend or during a âcontrolled crashâ when a side portion of the motorcycle slides upon the road surface.
System And Method For Maximizing Power Output From An Internal Combustion Engine
A system and method for maximizing power output from an internal combustion engine includes a control module , a motor power output measuring member , a microprocessor based digital computer , connections between a control module input and the computer , and connections between a control module output and one or more existing motor power variable control members including, but not limited to, fuel injectors, ignition timing components and air flow control components.
Device And Method For Maximizing Internal Combustion Engine Horsepower For A Preselected Rpm Range
A device and method for maximizing internal combustion engine horsepower for a preselected RPM range includes a plurality of velocity stacks removably inserted via grommets into apertures in an air box portion of the internal combustion engine while the air box portion is secured to a throttle body portion of the internal combustion engine, and measuring power generated by the engine for the preselected RPM range with a selected velocity stack removably secured to the air box portion whereby a velocity stack is ultimately selected that promotes maximum internal combustion engine horsepower for the preselected RPM range.
Carburetor Device With Additional Air-Fuel Flow Apertures
A carburetor device (10) having a plurality of apertures (12) circumferentially positioned and equally spaced around an orifice (14) portion of the carburetor device (10). The apertures (12) have a cross sectional area dimensioned to allow an air-fuel mixture to flow therethrough when a throttle member requires maximum power and corresponding air-fuel flow rates. The apertures (12) direct the air-fuel flow (30) through a "puddle" (27) of fuel that has accumulated in the bottom portion (28) of an outer well (18) of the carburetor (10) during the normal operation of an internal combustion engine. When maximum power is required from the engine, the increased air-fuel flow through the apertures (12) causes the fuel puddle (27) to vaporize or "mist", allowing the fuel to become a part of the air-fuel flow stream supplying the engine's cylinders (25) thereby increasing the engine's power and response while decreasing the engine's hydrocarbon emissions.
An adjustable interlocking ignition rotor device 10 includes a first member 12 having a plurality of orifices 34 radially positioned around the axis of the first member 12, a second member 14 having a plurality of orifices 56 radially positioned around the axis of the second member 14, and an index screw 16 to secure the first member 12 to the second member 14. The first and second members 12 and 14 are secured to a base portion of a distributor assembly or one end of a crankshaft to adjust the timing of an internal combustion engine. The engine timing is easily adjusted to an advanced or retarded position in relation to a zero degree setting by counting from a zero degree orifice 78 and 80 in both the first and second members 12 and 14 in a corresponding advanced or retarded direction, a quantity of orifices corresponding in number to a predetermined degree of engine timing. The selected orifices in the first and second members 12 and 14 are aligned and an index screw 16 is inserted thereby securing the position of the first member 12 in relation to the second member 14.
