    摘要： An opposed-piston engine includes a ported cylinder and a pair of pistons disposed to reciprocate in the bore of the cylinder. A combustion chamber is defined by opposing shaped piston end surfaces as the pistons approach respective top dead center (TDC) locations in the bore. At the end of scavenging, the shaped end surfaces of the pistons interact with swirl to produce turbulence in the charge air motion in the combustion chamber; the additional bulk motions include tumble. Fuel is injected into the turbulent charge air motion along a major axis, of the combustion chamber.

    摘要： An EGR system compensates for differing EGR flows and/or exhaust temperatures and can maintain the cooler exit temperature above the critical temperature, thereby reducing the possibility of EGR cooler fouling. A plurality of exhaust gas recirculation cooler modules is disposed between an exhaust gas passage and an air passage. The cooler modules receive exhaust gas from the exhaust gas passage and supply the received exhaust gas to the air passage for recirculation into an intake manifold. Each of the cooler modules includes a cooler portion, a bypass portion, and a flow control device. The cooler portion and the bypass portion are arranged such that fluid flowing through the cooler portion and the bypass portion flows therethrough without flowing through the other of the cooler portion and the bypass portion. The cooler portion reduces a temperature of the fluid flowing through the cooler portion.

    摘要： A control system and method for improving vehicle fuel economy is provided. A base timing module generates a base timing signal. A trim module generates a timing trim signal based on a calibratable compensation factor. A vehicle speed trim module adjusts a calibration parameter (such as engine timing for example) based on the base timing signal and the timing trim signal. According to some implementations, the trim module includes a base trim module and a vehicle speed compensation module and a calibratable compensation factor module. The vehicle speed compensation module generates a vehicle speed compensation factor. The base trim module generates a base trim signal based on the vehicle speed compensation factor or the calibratable compensation factor. The base trim signal can be based on a speed of the engine. The base trim signal can further be based on a quantity of fuel delivered to the engine.
