Configurable fuel injection system in an opposed piston engine

This disclosure describes a fully configurable injection system which can accomplish additional application cases than what is mentioned in US 2013/0104848, specifically the case where an injector is fired less than 2 times per engine rev Read the rest of this entry »

Coupling Crankshafts On An Opposed-Piston Engine With A Geartrain On Both Sides

Coupling Crankshafts On An Opposed-Piston Engine With A Geartrain On Both Sides

The subject matter relates to an opposed-piston engine that incorporates a pair of gear trains, or other coupling mechanisms, located on both ends of the pair of crankshafts driven by reciprocating pistons within the cylinders of the engine.

OIL SYSTEM WITH TWO PUMPS AND MEANS FOR CONTROLLING CONNECTING PASSAGES IN A TWO-STROKE, OPPOSED-PISTON ENGINE

OIL SYSTEM WITH TWO PUMPS AND MEANS FOR CONTROLLING CONNECTING PASSAGES IN A TWO-STOKE, OPPOSED-PISTON ENGINE

The subject matter relates to an opposed-piston engine that incorporates a pair of oil pumps, a piston thermal management (PMT) pump and a pump for lubricating all engine bearings and a means for controlling their respective outputs according to engine load demands by sharing the PTM pump output with the second pump output to ensure adequate lubrication of all bearings during low load engine condition such as engine idle mode.

DUAL CRANKSHAFT OPPOSED PISTON ENGINE WITH VARIABLE PORT TIMING

DUAL CRANKSHAFT, OPPOSED-PISTON ENGINE WITH VARIABLE PORT TIMING

A dual-crankshaft, opposed-piston, internal combustion engine includes one or more ported cylinders. Each cylinder has exhaust and intake ports, and the cylinders are juxtaposed and oriented with exhaust and intake ports mutually aligned. The crankshafts are rotatably mounted at respective exhaust and intake ends of the cylinders. A pair of pistons is disposed for opposed sliding movement in the bore of each cylinder. All of the pistons controlling the exhaust ports are coupled by connecting rods to the crankshaft mounted near at the exhaust ends of the cylinders, and all of the pistons controlling the intake ports are coupled by connecting rods to the crankshaft mounted near at the intake ends of the cylinders. The crankshafts are connected by a timing adjustment mechanism operative to change the rotational timing between the crankshafts, thereby to change the timing of exhaust and/or intake port timing.
