Embodiment Construction

[0018] An opposed-piston engine is an internal combustion engine characterized by the arrangement of two pistons disposed in the bore of a cylinder for reciprocating movement in opposite directions along the cylinder's longitudinal axis. An opposed-piston internal combustion engine differs in many respects from a conventional internal combustion engine with a single piston in the cylinder. In an opposed-piston engine, the combustion chamber is formed in the cylinder between the end faces of two opposed pistons moving in the cylinder; in a conventional engine, the combustion chamber is formed between the cylinder head and the end face of a single piston moving in the cylinder . In an opposed-piston engine, air enters the cylinder through a piston-controlled intake port that opens to the cylinder near one of its ends, and exhaust gas exits the cylinder through a piston-controlled exhaust port, which An exhaust port opens to the cylinder near the other of the two ends of the cyl...

Abstract

A hybrid drive system includes: an opposed piston internal combustion engine (52) including at least one cylinder (56) and a pair of pistons (57a, 57b) disposed in a bore of the cylinder for reverse sliding movement therein; a power transducer arrangement (53) coupled to be driven by the opposed piston internal combustion engine (52); and a hybrid powertrain system (55) configured to receive power from the power transducer arrangement (53).

Description

technical field [0001] The present invention relates to hybrid drive systems. In particular, the present invention relates to a hybrid drive system for a vehicle in which a non-combustion drive means provides mechanical torque and rotation to a drive shaft and an opposed-piston internal combustion engine means provides energy for the non-combustion drive system. Background technique [0002] Various international considerations are driving the need to improve energy efficiency and reduce undesired emissions from vehicles powered by internal combustion engines. These goals have led to the development of electric vehicles and hybrid electric trains for vehicles. Conventional internal combustion engines offer a low-cost platform with high power and energy density that meets consumer expectations for vehicle range, but still exhibits low fuel efficiency. Electric vehicles produce a low carbon profile with good driving characteristics (assumed low CO 2 grid). However, the ene...
