    摘要： Engine lubrication systems and methods of manufacturing and implementing engine lubrication systems and methods. In particular embodiments, an engine system includes an internal combustion engine lubrication system that utilizes a stacked configuration of a through-bolted engine to pattern around through-bolts and utilizes substantially hollow bulkheads to define a central high-pressure lubrication reservoir that minimizes lube system pressure while maintaining pressure at the extremities of the lubrication circuit. Available space is utilized within the bulkheads to provide a lubrication drainage restriction for reducing lubrication losses at engine shut-down.

    摘要： According to one embodiment, an apparatus for controlling fuel consumption in an internal combustion engine of a vehicle having a driver-actuated accelerator pedal includes an economy mode activation module and a standard fueling module. The economy mode activation module is configured to compare throttle input data with defined limits. The throttle input data is controllable by a driver of the vehicle via positioning of the accelerator pedal. The economy mode activation module is configured to control the fuel consumption of the internal combustion engine via an economy fuel map if the throttle input data falls within the defined limits for a defined amount of time. The standard fueling mode activation module is configured to control the fuel consumption of the internal combustion engine via a standard fuel map if the throttle input data does not fall within the defined limits for the defined amount of time.

    摘要： An apparatus, system and method for reducing the emission of nitrogen oxides in an internal combustion engine system. Exhaust gas directly or indirectly downstream of the internal combustion engine is at least selectively stored in an exhaust gas storage region. Upon the occurrence of at least one enablement condition, indicative of a potential period where the emission of nitrogen oxides (NOx) will increase, the stored exhaust gas is inserted into the internal combustion engine to assist in reducing the emission of the nitrogen oxides. The exhaust gas storage volume regularly, or the exhaust gas storage volume may be filled during strategic periods when the emissions of nitrogen oxides are low and/or there is a low need for the recirculation of exhaust gas.

    摘要： A system to detect the presence of a catalyst includes an exhaust gas tube, a first temperature sensing device, a second temperature sensing device, a flow rate measurement device, and a processing device. The first temperature sensing device measures a first temperature of exhaust gas upstream of the exhaust gas tube. The second temperature sensing device measures a second temperature of the exhaust gas downstream of the exhaust gas tube. The processing device estimates an expected time delay between the measured inlet and outlet exhaust gas temperatures corresponding to a system with a catalyst present. The processing device may also determine the presence of a catalyst by comparing the measured second temperature to the measured first temperature and comparing the measured second temperature to an estimated delayed first temperature associated with the expected time delay.
