    摘要: An opposed-piston engine includes an inline cylinder block with an open exhaust chamber that contains all of the engine's exhaust ports. Exhaust outlets open from the exhaust chamber through opposing sides of the cylinder block. A turbocharger is positioned on each side of the cylinder block and has an inlet closely coupled with a respective exhaust outlet. The exhaust chamber is divided into separate collector sections, each collector section containing the exhaust ports of one or more cylinders, and each turbocharger has a first inlet closely coupled with a first collector section and a second inlet closely coupled with a second collector section. The engine has a cylinder firing sequence which alternates between the cylinders in the first and second collector sections.

    摘要: A mechanism for varying crankshaft timing on a belt/chain driven, dual crankshaft opposed-piston engine includes sprockets on corresponding ends of the two crankshafts, connected by a belt or chain which is tensioned by two or more tensioners. By changing the position of the tensioners the length of the two spans of the belt/chain are varied and thus the phase between the crankshafts is varied.

    摘要: A combustion chamber for an opposed-piston engine is defined between a pair of pistons disposed for opposing reciprocal movement in a cylinder. The combustion chamber is formed between crowns of the pistons and has a radius that decreases from the longitudinal axis of the cylinder. Each crown includes a periphery, a bow! within the periphery defining a concave surface with a first portion curving inwardly toward the interior of the piston and a second portion curving outwardly from the interior, and a convex surface within the periphery curving outwardly and meeting the second portion of the concave surface to form a ridge. Each ridge has a height thai decreases with the distance from a longitudinal axis.
