In other words, the engine control device prevents excessive heating or insufficient heating by changing the oil temperature to the high side in a condition wherein the fuel being used does not easily vaporize, and changing the oil temperature to the low side in a condition wherein the fuel being used easily vaporizes. This engine control device includes an oil temperature controller that controls the temperature of oil lubricating the interior of the engine; a fuel supply device that supplies fuel to the engine; and a detector for detecting the property of the fuel. The temperature of the oil is controlled on the basis of a signal from the detector.

  • Patent number: 9628006
    Abstract: An apparatus includes a motor driver configured to drive a motor across a pair of input terminals to the motor and a current sense unit configured to sense the motor's electrical current amplitude. Further, an angular frequency extractor is operatively coupled to the motor driver and the current sense unit and configured to detect discontinuities in the motor's electrical current amplitude. The angular frequency extractor also is configured to determine a time period for one complete revolution of a rotor of the motor and to generate a feedback signal based on the determined period to control an angular frequency of the motor. The feedback signal may be used to adjust how the motor is being driven (e.g., to slow the motor down or speed it up).

  • Patent number: 9476367
    Abstract: A method that protects a direct injection fuel injector in a multi-fuel engine comprises selectively operating the engine with at least one of a directly injected fuel introduced through the direct injection fuel injector and a second fuel. When fuelling the multi-fuel engine with the second fuel, a fuel system protection technique is selectively commanded when one or more adverse conditions, such as the direct injection fuel injector requiring cooling, is determined to exist. The fuel system protection technique comprises (a) suspending fuelling with the second fuel and injecting the directly injected fuel for a first predetermined number of engine cycles, and (b) switching back to fuelling the multi-fuel engine with the second fuel for a second predetermined number of engine cycles. The first and second predetermined number of engine cycles are selected to keep torque disturbances below a predetermined threshold value.

  • Patent number: 9429096
    Abstract: Methods and systems are provided for controlling a vehicle engine to reduce cycle-to-cycle combustion variation. A predictive model is applied to predict cycle-to-cycle combustion behavior of an engine based on observed engine performance variables. Conditions are identified, based on the predicted cycle-to-cycle combustion behavior, that indicate high cycle-to-cycle combustion variation. Corrective measures are then applied to prevent the predicted high cycle-to-cycle combustion variation.

  • Patent number: 9371795
    Abstract: During high-load operation of an engine, fuel for initial slow-burning combustion and premixed combustion is injected into a combustion chamber by continuous fuel injection, then fuel injection is paused, and fuel for diffusion combustion is injected after a predetermined interval has elapsed. Also, the fuel injection amount in the continuous fuel injection is set higher than the fuel injection amount for diffusion combustion. A spray autointerference cooling effect is achieved by the continuous fuel injection, thus promoting ignition delay so as to increase the proportion of premixed combustion, thereby suppressing the production of smoke. This enables high-volume EGR to be performed, thus enabling reducing the amount of NOx produced.

  • Patent number: 9334799
    Abstract: A method of real-time estimation of the intensity of the knocking of an internal combustion engine utilizing a vibratory sensor is disclosed which is useful for control of internal combustion. A vibratory signal representing vibrations of the engine is continuously acquired as a function of the crankshaft angle. A model of a wave equation propagating through the cylinder-head is constructed. The coefficients of a Fourier decomposition of the vibratory signal are determined in real time by inverting the dynamics of the wave equation model using an estimator. The energy contained in the signal is computed by summing the squares of the coefficients of the Fourier decomposition. A parameter correlated with the intensity of knocking equal to the square root of the maximum of the energy is determined in real time.
