摘要： An EGR control apparatus for an internal combustion engine, which is capable of properly controlling an inert gas amount of two types of EGR gas supplied to cylinders of the engine via two paths different from each other, thereby making it possible to ensure a stable combustion state, reduced exhaust emissions, and improve operability. The EGR control apparatus includes low-pressure and high-pressure EGR devices, and an ECU. The ECU controls the low-pressure and high-pressure EGR gas amounts according to engine speed and demanded torque, and when a combination of engine speed and demanded torque is in a predetermined region, the low-pressure and high-pressure EGR gas amounts are controlled such that inert gas in low-pressure EGR gas exceeds in amount inert gas in high-pressure EGR gas, and the former more exceeds the latter as engine speed is higher or demanded torque is larger.

摘要： A piston construction for an opposed-piston engine accommodates contoured end surfaces of the piston crowns and articulation of the pistons with piston rods. The shape of each piston crown includes a bowl with an adjoining ridge that protrudes axially of the piston. A cooling construction for the piston includes an outer gallery running around the inner surface of the piston sidewall in the vicinity of the crown. The outer gallery girds and is in fluid communication with a central gallery that abuts the deepest part of the bowl. The outer gallery has an asymmetric profile that rises under the ridge and that slants upwardly under a peripheral portion of the bowl. A mechanism for coupling the piston to a piston rod includes a biaxial slipper bearing.

摘要： An engine has a LPL-EGR mechanism that recirculates low-pressure EGR gas from the downstream of a NSR catalyst in an exhaust gas emission system to an intake air system via a EGR cooler. A NOx-storage level is calculated for a low-temperature NOx-storing material and a high-temperature NOx-storing material carried on the NSR catalyst (step ST6). When the temperature of the NSR catalyst has risen quickly, a NOx-reducing process is carried out if it is predicted that most of the NOx released by the low-temperature NOx-storing material is not stored by the high-temperature NOx-storing material, hence escaping from the NSR catalyst (step ST9). The NOx-reducing process reduces the amount of NOx flowing into the LPL-EGR mechanism and restrains an aqueous acid solution from being produced from NOx, thereby preventing corrosion of the EGR cooler.

摘要： It is possible to suppress fluctuations of an air intake amount when the open degree of an air intake control valve is unknown. An engine (200) includes an impulse valve (224) common to all the cylinders arranged in the engine (200). The impulse valve (224) is arranged in a communicating tube (206) provided at the downstream side of a serge tank (205). An ECU (100) executes impulse valve drive control. In the control, the ECU (100) judges whether a rotation angle sensor (225) which detects the open degree of the impulse valve (224) has failed. If it is judged that the rotation angle sensor (225) has failed, the ECU (100) controls a drive motor (224C) and a drive circuit (224D) for driving a valve body so that a valve body (224A) of the impulse valve (224) rotates inside the communicating tube (206). Here, the rotor of the drive motor (224C) which defines the rotation speed of the valve body (224A) has an rpm which is set in accordance with the mechanical rpm NE of the engine (200).

摘要： This anomaly determination system is provided with an inlet pressure sensor (31) which detects the inlet pressure of a pressure loss unit (26) provided in the fluid passage (25) in a vehicle, an outlet pressure sensor (32) which detects the outlet pressure of the pressure loss unit (26), an atmospheric pressure sensor (33) which detects the atmospheric pressure, which is the pressure outside of the fluid passage (25), and an anomaly determination unit (35) which determines anomalies in the pressure loss unit (26). The anomaly determination unit (35) determines that there is an anomaly in the pressure loss unit (26) if the difference between the inlet and outlet pressure, the difference between the outlet and atmospheric pressure, and the difference between the outside and inlet pressure, detected when the flow rate in the fluid passage (25) is less than the minimum flow rate at which anomalies in the pressure loss unit (26) are detectable, are within an allowable range, and the pressure difference between the inlet pressure and outlet pressure when the flow rate is greater than or equal to the minimum flow rate is within a first pressure loss range.

摘要： A GDCI engine (12) has a piston (16) arranged within a cylinder (14) to provide a combustion chamber (18). According to one embodiment, the GDCI engine (12) operates using a method that includes the steps of supplying a hydrocarbon fuel to the combustion chamber (18) with a research octane number in the range of about 30-65. The hydrocarbon fuel is injected in completely stratified, multiple fuel injections before a start of combustion and supplying a naturally aspirated air charge to the combustion chamber (18).

摘要： A system for cooling charge air and excess fuel for a turbocharged diesel engine includes a charge air cooler having an inlet body, a heat exchanger that is disposed downstream from the inlet body and an outlet body that is disposed downstream from the heat exchanger. The outlet body defines a flow passage in fluid communication with the heat exchanger. The system further includes a fuel passage that is in thermal communication with the flow passage of the outlet body. A method for cooling excess fuel from the turbocharge diesel engine is also disclosed herein.
