20090007641 | METHOD TO TEST FOR A LEAK IN A FUEL TANK SYSTEM - Method to test for a leak in a fuel tank system of a motor vehicle with the following steps:
| 01-08-2009 |
20090025458 | Rate-based monitoring for an engine system - Rate based monitoring includes performing test cycles on a monitored system when predetermined conditions are met. Completion of a test cycle is determined by timing a period that is at least as long as the longer of a time required to detect a correct operation of the monitored system and a time to detect a malfunction of the monitored system, the timing being reset if one or more of the predetermined conditions cease to be met. A count is kept of completed test cycles. | 01-29-2009 |
20090165535 | LEAK LOCALIZATION IN A CAVITATED BODY - The present invention includes a method and system using dynamic pressure measurements for determining a presence, location, and size of a leak in a chamber of a body. The method includes sealing a plurality of ports of the chamber, pressurizing the chamber with a fluid, measuring a dynamic pressure at each of the plurality of ports, and analyzing the dynamic pressure measured at each of the plurality of ports to determine a presence, location, and/or size of the leak. The location of the leak can be determined by analyzing magnitude and/or phase values from a generated frequency response function matrix, interpolating between two of the plurality of ports, triangulating between three of the plurality of ports, and/or analyzing a rate and profile at which the pressure decays at each of the plurality of ports to determine the location of the leak. | 07-02-2009 |
20090301174 | Cooling system pressure tester - An apparatus for checking pressure leaks in a vehicle's heating and cooling system, such system including a radiator, top and bottom hoses, a water pump, a heater, a thermostat and connecting hoses. The apparatus comprises a test head for engagement with a neck of a radiator in place of a radiator cap. There is a gauge member in fluid communication with the test head for measuring an actual pressure on such cooling system. An air control valve is in fluid communication with the test head and the gauge member for regulating how much air pressure is going to such cooling system. The apparatus, further, has a handle control member that is in fluid communication with the test head, the gauge member and the air control valve and further is in fluid communication with a shop air hose for controlling how much air pressure is going to the air control valve. There is also a hose and appropriate fittings for providing fluid communication with the test head, the gauge member, the air control valve, the handle control member and such shop air hose for providing pressurized air to such cooling system. | 12-10-2009 |
20120279282 | Device and method to provide a pressure/vacuum test of a vehicle cylinder's sealing ability without a head on the engine - A device for pressure testing an engine block may include a sealing device to mount on the engine block and to seal the engine block, a fastening device to fasten the sealing device to the engine block and a connecting rod to connect the sealing device to the fastening device. The sealing device may include a layer of adhesive on the bottom surface of the sealing device, and the sealing device includes a substantial cylinder. The sealing device may include a aperture, and the sealing device may include a threaded port. | 11-08-2012 |

20130192347 | OIL MIGRATION SYSTEM - An apparatus and a system is provided that may be utilized to determine oil migration and oil displacement from a pre-oiled air filter. The present invention may also be utilized to determine if oil is displaced from the air filter onto a portion of the apparatus for visualization to a user. The present invention utilizes a demonstration apparatus having a system for forcing air through the oil subjected air filter thereby attempting to force displacement of the oil from the air filter. The apparatus utilizes a blowing means whereby the oil infused air filter is subject to higher than normal air flow and whereby the apparatus has a deflection portion whereby if oil is displaced from the air filter, it is deflected onto the deflection portion where it would be physically viewable to an observer present in the vicinity of the apparatus. | 08-01-2013 |
20140290345 | Oil Migration System - An apparatus and a system is provided that may be utilized to determine oil migration and oil displacement from a pre-oiled air filter. The present invention may also be utilized to determine if oil is displaced from the air filter onto a portion of the apparatus for visualization to a user. The present invention utilizes a demonstration apparatus having a system for forcing air through the oil subjected air filter thereby attempting to force displacement of the oil from the air filter. The apparatus utilizes a blowing means whereby the oil infused air filter is subject to higher than normal air flow and whereby the apparatus has a deflection portion whereby if oil is displaced from the air filter, it is deflected onto the deflection portion where it would be physically viewable to an observer present in the vicinity of the apparatus. | 10-02-2014 |
20160084755 | EVAPORATIVE VEHICLE EMISSION LOSS DETECTION FROM A NON-OPERATING VEHICLE - An evaporative gas analysis system and method for detecting and measuring levels of hydrocarbons emitted from gasoline motor vehicles while stationary with the engine off includes a monochromatic source for producing and transmitting a beam of visible radiation through a portion of hydrocarbon gas surrounding the motor vehicle thereby causing the gas surrounding the vehicle to emit chromatic radiation based on the gas present. A receiver is positioned to receive the emitted chromatic radiation. The receiver including a plurality of chromatic sensors, each generating an electrical signal indicative of transmission of hydrocarbon gas surrounding the vehicle. A control is responsive to the chromatic sensors for computing the relative concentration of hydrocarbon gas surrounding the vehicle from the electrical signals. | 03-24-2016 |
