  • Publication number: 20170234246
    Abstract: A method for a vehicle engine is presented, wherein during a first condition, a vehicle controller is placed in a sleep mode following a vehicle-off event and then awoken following a duration, at which time contents of an air intake system hydrocarbon trap are purged to a fuel vapor canister by operating an electric motor to rotate the vehicle engine in a reverse direction. Rotating the vehicle engine in a reverse direction causes atmospheric air to enter an intake of the engine via an exhaust of the engine, desorbing hydrocarbons bound to the air intake system hydrocarbon trap. By porting the desorbed hydrocarbons to the fuel vapor canister, bleed emissions from the air intake system hydrocarbon trap may be reduced.

    Abstract: A control system includes a processor for controlling an internal combustion engine having a temperature region, wherein a change of ignition delay time accompanying a rise in a cylinder temperature when the cylinder temperature is in the temperature region is smaller than when the cylinder temperature is out of the temperature region. When a self ignition timing of secondary fuel is earlier than a self ignition timing of primary fuel due to the secondary fuel being injected at a crank angle at which the cylinder temperature is higher than the temperature region, the processor controls a ratio of the secondary fuel to be lower than when the self ignition timing of the secondary fuel is later than the self ignition timing of the primary fuel due to the secondary fuel being injected at a crank angle at which the cylinder temperature is within the temperature region.

  • Publication number: 20170234253
    Abstract: Methods and arrangements for transitioning an engine between a deceleration cylinder cutoff (DCCO) state and an operational state are described. In one aspect, transitions from DCCO begin with reactivating cylinders to pump air to reduce the pressure in the intake manifold prior to firing any cylinders. In another aspect, transitions from DCCO, involve the use of an air pumping skip fire operational mode. After the manifold pressure has been reduced, the engine may transition to either a cylinder deactivation skip fire operational mode or other appropriate operational mode. In yet another aspect a method of transitioning into DCCO using a skip fire approach is described. In this aspect, the fraction of the working cycles that are fired is gradually reduced to a threshold firing fraction. All of the working chambers are then deactivated after reaching the threshold firing fraction.

    Abstract: A GDCI engine recirculates exhaust gases to a combustion chamber using desired early injection parameters for a steady state engine operation from a controller. An engine control system detects a load increase relative to the steady state engine operation, and insufficient recirculated exhaust gases to the combustion chamber are delivered in response to the detected load increase as a result of transport delays. A last fuel injection into the combustion chamber during an engine cycle with multiple fuel injections is delayed as compared to the steady state engine operation. Combustion phasing within the combustion chamber is retarded in response to the delayed injection.

Fuel moves in a circuit from the supply to the inlet port, thence through the filter element in the chamber, thence out the outlet port to the engine where a portion of the fuel is consumed and a portion of it is heated and flowed back to the return-fuel inlet, and thence through the passage and out the return-fuel outlet to the supply.

    Abstract: Methods and systems are provided for cooling a high pressure fuel pump. One method includes, when a spill valve is in a pass-through state, circulating fuel from a compression chamber of the high pressure fuel pump to a step room of the high pressure fuel pump. The fuel circulation through the step room may provide for a reduction in fuel temperature in the step room, and thus, the high pressure fuel pump.

    Abstract: An internal combustion engine includes a spark plug which protrudes into a combustion chamber. The spark plug has a central electrode and a ground electrode, and is configured such that a spark is generated between the central electrode and the ground electrode by electrical discharge. The spark plug has a vortex generator that separates an air flow near the ground electrode from the ground electrode and generates a vortex at a downstream side. The central electrode and the ground electrode are placed in a manner such that a spark or a flame deformed by an air flow flowing between the central electrode and the ground electrode enters the trailing vortex, or the spark penetrates through the inside of the trailing vortex.
