  • Diesel engine diagnostic system
    Patent number: 4518268
    Abstract: A system for analyzing a diesel engine and transmitting data regarding faults within the diesel engine. Many diesel engines include glow plugs. The electrical characteristics of glow plugs are related to temperatures within the diesel engine which, in turn, are related to the operational characteristics of the diesel engine. The system measures the electrical characteristics of a glow plug, or other sensors, to determine attributes of the diesel engine and responsively provide a display representative of the operational characteristics.
    Type: Grant
    Filed: March 18, 1983
    Date of Patent: May 21, 1985
    Assignee: Sun Electric Corporation
    Inventors: Philip E. Swis, Anthony E. DiFonzo
  • System for hot testing engines
    Patent number: 4285233
    Abstract: A preferred embodiment of the system for hot testing automobile engines includes a hot test station and an indexing mechanism, or conveyor, for advancing engines to the hot test station. The engines are operated during advancement such that normalization is achieved prior to reaching the hot test station.

  • Test stand for an internal combustion engine testing system
    Patent number: 4174627
    Abstract: A test stand for an internal combustion engine testing system is disclosed. The test stand permits the engine to substantially freely vibrate such that engine imbalance can be measured. The test stand includes a cradle and a support assembly, having a housing and an inflatable bladder member. The bladder member supports the cradle during the testing operation.

  • Drive-dynamometer system
    Patent number: 3942363
    Abstract: A drive-dynamometer system particularly adapted for automated testing of parts such as vehicle engines. The dynamometer is a hydrostatic system having a fixed displacement motor connected to, and a variable displacement pump spaced from the part being tested, the pump having motor means for driving it. The system has a closed hydraulic loop connecting the motor and the pump whereby the engine may be selectively cold-tested or hot-tested, the motor during hot-testing acting as a pump and the pump acting as a motor which therefore drives its motor means. Preferably, this comprises a synchronous electric motor, which, when acting as a generator, creates useful electric power for the plant in which the unit is installed. Means are provided for adjusting the displacement of the pump, and a control loop system is provided for the pump adjusting means to simulate different load or inertia conditions.
