    Abstract: Methods and systems are provided for operating a pre-chamber to provide ignition to a cylinder during catalyst heating. In one example, a method may include injecting fuel and air into a pre-chamber of an engine cylinder during an expansion stroke of the engine cylinder responsive to a temperature of a catalyst being less than a threshold temperature, and injecting the fuel and the air into the pre-chamber during a compression stroke of the engine cylinder responsive to the temperature of the catalyst being greater than or equal to the threshold temperature. In this way, the pre-chamber may provide robust ignition to the cylinder during a variety of operating conditions.

  • Patent number: 11236706
    Abstract: An intake passage of an engine includes a throttle valve, a supercharger, and a bypass passage connecting an upstream side with a downstream side of the supercharger and opening when the supercharger is not acting. When the supercharger is not acting, the intake passage generates forward flows in which intake air flows from the throttle valve toward the supercharger and bypass-directed flows in which the intake air is reversed due to blockage of forward movement by the supercharger and flows from the supercharger side toward a connection port, of the bypass passage, opening in the intake passage. An evaporated fuel introduction opening leading evaporated fuel produced in a fuel tank to the intake passage opens in a wall surface, on which the bypass-directed flow is generated, in the intake passage.

  • Patent number: 10294879
    Abstract: A control apparatus for an internal combustion engine with a supercharger includes a boost-pressure detector. When first boost pressure control to control the supercharger such that a boost pressure reaches a target pressure starts, starts, the target pressure is set to an initial target pressure, gradually at a first rate, and then gradually increased to a steady-state target boost pressure at a second rate smaller than the first rate if the boost pressure is equal to or higher than a threshold pressure. Second boost pressure control is performed such that the boost pressure reaches a steady-state target boost pressure. Inhibiting/allowing circuitry is configured to inhibit execution of the first boost pressure control and allow execution of the second boost pressure control if the boost pressure is lower than the steady-state target boost pressure and if the steady-state target boost pressure is lower than the threshold pressure.

  • Patent number: 10233756
    Abstract: A two-sided turbocharger compressor wheel and a housing forming a diffuser for the compressor. A first side and a second side of the compressor wheel are characterized by different values of a trim and of an annulus area. A first side of the diffuser surrounds the first side of the compressor wheel, and a second side of the diffuser surrounds the second side of the compressor wheel. The first and second sides of the diffuser are characterized by different annulus area ratios. The blades of the first and second sides of the compressor wheel are angularly offset from one another. The compressor wheel is configured for greater flow through the side of the compressor wheel that faces away from a related turbine wheel.

  • Patent number: 10174719
    Abstract: In a non-EGR region that is a light load operating region, an EGR control valve (21) is opened at a predetermined infinitesimal opening degree M that corresponds to such infinitesimal EGR ratio as not to affect an ignition timing. With this control, since an EGR passage (20) is basically in a state in which the EGR passage (20) is filled with EGR gas, when an operating condition is changed from the non-EGR region to an EGR region and the EGR control valve (21) is opened so as to gain a target EGR ratio, a desired quantity of the EGR gas is introduced into an intake passage (2) substantially at the same time as the opening of the EGR control valve (21). An actual EGR ratio can thus follow the target EGR ratio with a good response.

  • Patent number: 10174672
    Abstract: An electric waste gate valve control device controls a waste gate valve provided in a waste gate passage that bypasses a portion between an upstream and a downstream of a turbine driven by exhaust of an engine and opening/closing the waste gate passage by an electric actuator. The electric waste gate valve control device includes: a position sensor that detects a position of the waste gate valve; an actuator controller that controls the electric actuator such that an opening degree of the waste gate valve becomes a target opening degree; and a fully closed position learning unit that performs fully closed position learning to acquire the position of the waste gate valve at a time when the electric actuator is driven to bring the waste gate valve into a fully closed state.

  • Patent number: 10125698
    Abstract: A variable speed hybrid electric supercharger assembly is controlled to regulate an adaptive state of charge of an energy storage device and/or to boost an engine based on a performance mode selected by a driver. In one example, a reference state of charge is determined based upon driving characteristics of a vehicle and compared to an actual state of charge of the energy storage device. If the difference indicates a deficit, an operation mode is selected to regenerate the energy storage device. In another example, a planetary gearing arrangement between an engine and an electric motor is configured to increase or decrease power transferred to the supercharger by the engine based upon the performance mode selected by the driver.

  • Patent number: 10119480
    Abstract: An object is to supply fresh air and EGR gas into a cylinder in good balance according to the required load in a naturally aspirated gasoline engine. When the operation state of the engine falls in a low load range, a control apparatus adjusts the degree of opening of the second throttle while keeping the first throttle fully open and controls EGR gas quantity by adjusting the degree of opening of the EGR valve. When the operation state falls in a middle load range, the apparatus controls EGR gas quantity by adjusting the degree of opening of the first throttle while keeping the EGR valve fully open. When the operation state falls in a high load range, the apparatus adjusts the degree of opening of the first throttle while keeping the second throttle fully open and controls EGR gas quantity by adjusting the degree of opening of the EGR valve.
