  • Patent number: 8720418
    Abstract: The invention relates to a fuel injection system of the common rail type having a rail body comprising a central bore and one or more outlet bores in fluid communication with the central bore for communicating with a respective fuel injector. The outer circumference of the rail body is substantially oval in cross-section and is thicker in cross-section in a direction substantially perpendicular to the outlet bore axis as compared to the thickness in cross-section substantially parallel to the outlet bore axis. By increasing the thickness of the rail body in this way, stresses at the intersection of the intersection of the central bore with the outlet holes may be reduced by up to 10% or more, thereby increasing the acceptable cycled running pressure of the system.

  • Patent number: 8706385
    Abstract: An exhaust gas recirculation device of an internal combustion engine (1) including a low-pressure EGR passage (20), a high-pressure EGR passage (21), a low-pressure EGR valve (23) and a high-pressure EGR valve (24) further includes an air-fuel ratio sensor (12) that is disposed in the exhaust passage (4) upstream of the position of its connection with the low-pressure EGR passage (20). In the case where a predetermined fuel-cut condition is satisfied, an ECU (30) estimates the flow amounts of exhaust gas flowing in the low-pressure EGR passage (20) and the high-pressure EGR passage (21), on the basis of the oxygen concentrations acquired by the air-fuel ratio sensor (12) at timings at which the exhaust gases recirculated into the intake passage (3) via the low-pressure EGR passage (20) and via the high-pressure EGR passage (21) reach the air-fuel ratio sensor (12), respectively.

  • Patent number: 8662058
    Abstract: An electronic ignition module for vintage automobiles that utilizes existing components and wiring to retain the look and operation of the original system but with superior performance. The ignition module replaces the original roller and contacts of a vintage automobile ignition timer with modern control electronics that actuate the original coils and original spark plugs using the original wiring in the original manor. Electronic ignition operation is user programmable to emulate the original roller/timer performance or provide automatic spark advance similar to modern automobile operation for optimum power and efficiency while freeing the operator from manual adjustment of spark timing. Ignition module programming is accomplished without any external switches, buttons, jumpers or modification to the vintage automobile by simply sensing the presence or absence of ignition coils connected to the system when power is applied.

  • Patent number: 8640676
    Abstract: An evaporated fuel treatment apparatus includes a control valve having a dead zone range in which an evaporated fuel is blocked even if the opening angle is increased from a close position in opening direction and a communicating range in which the evaporated fuel is allowed to flow therethrough when opening angle is increased from the dead zone range. A control unit determines whether the opening angle is switched between the dead zone range and the communicating range. The switching is determined on the basis of a pressure inside the fuel tank detected with a pressure sensor and an air-fuel ratio detected by an air-fuel ratio sensor. A control valve installed in a communication path between a fuel tank and a canister is prevented from being seized.

  • Patent number: 8635007
    Abstract: Embodiments for determining NH3 slip past a catalyst are provided. In one example, a filtering method for a NOx sensor of an exhaust gas system having an SCR catalytic converter comprises determining NOx concentration upstream of the catalytic converter, measuring NOx concentration downstream of the catalytic converter, modeling NOx conversion, modeling NH3 slip behavior, calculating a NOx error of the NOx modeling, calculating an NH3 error of the NH3 modeling, assigning data of the NOx sensor as NH3 measured values when a ratio of the NOx error to the NH3 error is greater than an upper threshold value, and assigning data of the NOx sensor as NOx measured values when the ratio of the NOx error to the NH3 error is smaller than a lower threshold value. In this way, NOx slip and NH3 slip may be determined from a common sensor.

  • Patent number: 8627798
    Abstract: A direct fuel-injection engine includes a piston, a cavity recessed in a central part of a top face of the piston, and a fuel injector. At a main injection collision point of a fuel-injection axis when main injection is performed while the piston is near top dead center, a main injection collision angle formed between its tangent and the fuel-injection axis is set at an obtuse angle. Fuel colliding with the main injection collision point is deflected towards a cavity open end side. At a secondary injection collision point of the fuel-injection axis when performing secondary injection with the piston is further from top dead center, a secondary injection collision angle formed between its tangent and the fuel-injection axis is set at one of a right angle and an acute angle. Fuel colliding with the secondary injection collision point is deflected primarily in the circumferential direction of the cavity.
