  • Publication number: 20030115944
    Abstract: It is becoming more common for diesel engine cylinders to include an engine compression release brake that can utilize energy built up in the cylinder to provide additional braking for the vehicle. The present invention utilizes a software diagnostic test that is stored in an electronic control module to detect defects in the engine compression release brakes. In particular, the present invention operates a first portion of the engine cylinders in a power mode and a second portion of the engine cylinders in a braking mode and compares a resulting fuel injector response or engine response to an expected value to determine if one or more of the engine compression release brakes are performing as expected.

  • Patent number: 6474620
    Abstract: The present invention finds application in hydraulically actuated valves, such as gas exchange valves, having a valve member that moves within a valve body between an open position and a closed position. In valves such as these, the valve member typically includes a valve surface that contacts a valve seat included on the valve body when moving to its closed position. However, the impact velocity when the valve surface contacts the valve seat can be quite high. This can lead to fatigue of the valve stem and can wear out the valve seat, both of which can shorten the effective life of the valve. Therefore, the present invention includes a hydraulic pulse generator for slowing movement of the valve member which includes the direction of a hydraulic pulse toward the valve member as the valve member moves from its open position to its closed position.

  • Patent number: 6418906
    Abstract: A method of engine compression release braking includes an initial step of compressing gas in an engine cylinder. A compression release brake valve is then opened at least in part by fluidly connecting a brake actuator to a source of high pressure actuation fluid. Next, a valve closing timing that results a valve seating velocity that is less than a pre-determined velocity is determined. The compression release brake valve is then closed at the valve closing timing at least in part by fluidly connecting the brake actuator to a low pressure actuation fluid reservoir.

  • Patent number: 6354266
    Abstract: An enhanced warm-up operation mode operates a first portion of engine cylinders in a power mode and a second portion of engine cylinders in a braking mode. More fuel is injected into the powered cylinders in order to maintain engine speed and overcome the retarding force of the engine compression release brakes on the braking cylinders. The engine cycles through which cylinders are powered and which are braking during the warm-up procedure. The process reduces emissions, such as white smoke, that are common during cold start conditions.

  • Patent number: 6349920
    Abstract: A spool slides in a bore to open and close a valve. The spool moves in a first direction until the spool forcibly engages a seat in the bore, closing the valve. The spool moves in a second direction opposite the first direction so that the spool disengages with the seat, opening the valve. Proper configuration of the spool and bore geometries in the vicinity of the seat keeps static pressure from developing that could otherwise retard spool valve opening.

  • Patent number: 6330547
    Abstract: A method and apparatus for deciding whether to make a loan using an intangible asset, such as intellectual property, as collateral and for making such a loan more attractive to a lender. The method requires that an assessment of the transferability and viability of the asset be made to determine if the asset and loan applicant meet minimum qualifying criteria. If they do, a more detailed analysis is undertaken in which judgments are reached concerning various factors related to historical, comparative and prospective market behavior in market sectors identical with, as well as parallel and corollary to the primary market sector for the asset sought to be used as loan collateral. The analysis leads to calculation of an asset liquidation value and production of a correlated depreciation schedule which are both presented to the prospective lender.
